Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1.
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	NATURE OF OPERATIONS
	Domtar designs, manufactures, markets and distributes a wide variety of fiber-based products including communication papers, specialty and packaging papers and absorbent hygiene products. The foundation of its business is the efficient operation of pulp mills, converting fiber into paper grade, fluff and specialty pulps. The majority of this pulp production is consumed internally to make communication papers, specialty and packaging papers and personal care products with the balance sold as a market pulp. Domtar is the largest integrated marketer and manufacturer of uncoated freesheet paper in North America, serving a variety of customers, including merchants, retail outlets, stationers, printers, publishers, converters and end-users. In addition, Domtar is also a leading marketer and producer of a broad line of incontinence care products, marketed primarily under the Attends®, IncoPack® and Indasec® brand names, as well as baby diapers. The Company also owns and operates Ariva®, a network of strategically located paper distribution facilities in Canada.
	ACCOUNTING PRINCIPLES
	The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of Domtar Corporation and its controlled subsidiaries. Intercompany transactions have been eliminated on consolidation. Investment in an affiliated company, where the Company has joint control over their operations, is accounted for by the equity method.
	USE OF ESTIMATES
	The consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the year, the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. On an ongoing basis, management reviews the estimates and assumptions, including but not limited to those related to closure and restructuring costs, income taxes, useful lives, asset impairment charges, goodwill and intangible asset impairment assessment, environmental matters and other asset retirement obligations, pension and other post-retirement benefit plans and, commitments and contingencies, based on currently available information. Actual results could differ from those estimates.
	TRANSLATION OF FOREIGN CURRENCIES
	The Company determines its international subsidiaries’ functional currency by reviewing the currencies in which their respective operating activities occur. The Company translates assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using the rate in effect at the balance sheet date and revenues and expenses are translated at the average exchange rates during the year. Foreign currency translation gains and losses are included in Shareholders’ equity as a component of Accumulated other comprehensive loss in the accompanying Consolidated Balance Sheets.
	Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is recognized in the Consolidated Statements of Earnings and Comprehensive Income and is partially offset by our hedging program (refer to Note 23 “Derivatives and hedging activities and fair value measurement”).
	At December 31, 2014, the accumulated translation adjustment accounts amounted to $(48) million (2013 – $152 million).
	REVENUE RECOGNITION
	Domtar Corporation recognizes revenue when pervasive evidence of an arrangement exists, the customer takes title and assumes the risks and rewards of ownership, the sales price charged is fixed or determinable and when collection is reasonably assured. Revenue is recorded at the time of shipment for terms designated free on board (“f.o.b.”) shipping point. For sales transactions designated f.o.b. destination, revenue is recorded when the product is delivered to the customer’s delivery site, when the title and risk of loss are transferred.
	SHIPPING AND HANDLING COSTS
	The Company classifies shipping and handling costs as a component of Cost of sales in the Consolidated Statements of Earnings and Comprehensive Income.
	CLOSURE AND RESTRUCTURING COSTS
	Closure and restructuring costs are recognized as liabilities in the period when they are incurred and are measured at their fair value. For such recognition to occur, management, with the appropriate level of authority, must have approved and committed to a firm plan and appropriate communication to those affected must have occurred. These provisions may require an estimation of costs such as severance and termination benefits, pension and related curtailments, environmental remediation and may also include expenses related to demolition and outplacement. Actions taken may also require an evaluation of any remaining assets to determine required write-downs, if any, and a review of estimated remaining useful lives which may lead to accelerated depreciation expense.
	Estimates of cash flows and fair value relating to closures and restructurings require judgment. Closure and restructuring liabilities are based on management’s best estimates of future events at December 31, 2014. Closure and restructuring cost estimates are dependent on future events. Although the Company does not anticipate significant changes, the actual costs may differ from these estimates due to subsequent developments such as the results of environmental studies, the ability to find a buyer for assets set to be dismantled and demolished and other business developments. As such, additional costs and further working capital adjustments may be required in future periods.
	INCOME TAXES
	Domtar Corporation uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined according to differences between the carrying amounts and tax bases of the assets and liabilities. The Company records its worldwide tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. The change in the net deferred tax asset or liability is included in Income tax (benefit) expense or in Other comprehensive (loss) income in the Consolidated Statements of Earnings and Comprehensive Income. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to apply in the years in which the assets and liabilities are expected to be recovered or settled. Uncertain tax positions are recorded based upon the Company’s evaluation of whether it is “more likely than not” (a probability level of more than 50 percent) that, based upon its technical merits, the tax position will be sustained upon examination by the taxing authorities. The Company establishes a valuation allowance for deferred tax assets when it is more likely than not that they will not be realized. In general, “realization” refers to the incremental benefit achieved through the reduction in future taxes payable or an increase in future taxes refundable from the deferred tax assets.
	The Company recognizes interest and penalties related to income tax matters as a component of Income tax (benefit) expense in the Consolidated Statements of Earnings and Comprehensive Income.
	CASH AND CASH EQUIVALENTS
	Cash and cash equivalents include cash and short-term investments with original maturities of less than three months and are presented at cost which approximates fair value.
	RECEIVABLES
	Receivables are recorded net of a provision for doubtful accounts that is based on expected collectability. The securitization of receivables is accounted for as secured borrowings. Accordingly, financing expenses related to the securitization of receivables are recognized in earnings as a component of Interest expense in the Consolidated Statements of Earnings and Comprehensive Income.
	INVENTORIES
	Inventories are stated at the lower of cost or market. Cost includes labor, materials and production overhead. The last-in, first-out (“LIFO”) method is used to cost certain U.S. raw materials, in process and finished goods inventories. LIFO inventories were $229 million and $215 million at December 31, 2014 and 2013, respectively. The balance of U.S. raw material inventories, all materials and supplies inventories and all foreign inventories are costed at either the first-in, first-out (“FIFO”) or average cost methods. Had the inventories for which the LIFO method is used been valued under the FIFO method, the amounts at which product inventories are stated would have been $66 million and $72 million greater at December 31, 2014 and 2013, respectively.
	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment are stated at cost less accumulated depreciation including asset impairment write-downs. Interest costs are capitalized for significant capital projects. For timberlands, the amortization is calculated using the unit of production method. For all other assets, amortization is calculated using the straight-line method over the estimated useful lives of the assets. Buildings and improvements are amortized over periods of 10 to 40 years and machinery and equipment over periods of 3 to 20 years. No depreciation is recorded on assets under construction.
	IMPAIRMENT OF LONG-LIVED ASSETS
	Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances indicating that the carrying value of the assets may not be recoverable, as measured by comparing the net book value of the asset group to their estimated undiscounted future cash flows. Impaired assets are recorded at estimated fair value, determined principally by using discounted future cash flows expected from their use and eventual disposition (refer to Note 4 “Impairment and write-down of property, plant and equipment and intangible assets”).
	GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill is not amortized and is evaluated at the beginning of the fourth quarter of every year, or more frequently, whenever indicators of potential impairment exist. The Company performs the impairment test of goodwill at its reporting unit’s level.
	The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount including goodwill. In performing the qualitative assessment, the Company identifies the relevant drivers of fair value of a reporting unit and the relevant events and circumstances that may have an impact on those drivers of fair value. This process involves significant judgement and assumptions including the assessment of the results of the most recent fair value calculations, the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, specific events affecting the Company and the business, and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill, then it performs Step I of the two-step impairment test. The Company can also elect to bypass the qualitative assessment and proceed directly to the Step I of the impairment test.
	The first step is to compare the fair value of a reporting unit to its carrying amount, including goodwill. Significant judgement is required to estimate the fair value of a reporting unit.
	The Company typically uses an income method to determine the fair value of a reporting unit. Under the income approach, the Company estimates the fair value of a reporting unit based on the present value of estimated future cash flows. The assumptions used in the model requires estimating future sales volumes, selling prices and costs, changes in working capital, investments in property, plant and equipment and the selection of the appropriate discount rate. Sensitivities of these fair value estimates to change in assumptions are also performed. Assumptions used in our impairment evaluations are consistent with internal projections and operating plans. Unanticipated market and macroeconomic events and circumstances may occur and could affect the exactitude and validity of management assumptions and estimates.
	In the event that the net carrying amount exceeds the fair value of the business, the second step of the impairment test must be performed in order to determine the amount of the impairment charge. Fair value of goodwill in Step II of the impairment test is estimated in the same way as goodwill was determined at the date of the acquisition in a business combination, that is, the excess of the fair value of the reporting unit over the fair value of the identifiable net assets of the business.
	All goodwill as of December 31, 2014 resides in the Personal Care reporting segment, and originates from the acquisitions of Attends Healthcare Inc. on September 1, 2011, Attends Healthcare Limited on March 1, 2012, EAM Corporation on May 10, 2012, AHP on July 1, 2013 and Laboratorios Indas on January 2, 2014. Please refer to Note 3 “Acquisition of businesses” for additional information regarding the most recent acquisition.
	Indefinite-lived intangible assets are not amortized and are evaluated at the beginning of the fourth quarter of every year, or more frequently whenever indicators of potential impairment exist. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of indefinite-lived intangible assets are less than their carrying amounts. The qualitative assessment follows the same process as the one performed for goodwill, as described above. If, after assessing the qualitative factors, the Company determines that it is more likely than not that the indefinite-lived intangible assets are less than their carrying amounts, then a quantitative impairment test is required. The Company can also elect to proceed directly to the quantitative test. The quantitative impairment test consists of comparing the fair value of the indefinite-lived intangible assets determined using a variety of methodologies to their carrying amount. If the carrying amounts of the indefinite-lived intangible assets exceed their fair value, an impairment loss is recognized in an amount equal to that excess. Indefinite-lived intangible assets include trade names related to Attends®, IncoPack®, Indasec®, catalog rights related to Laboratorios Indas S.A.U., and license rights related to Xerox. The Company reviews its indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support indefinite useful lives.
	Definite lived intangible assets are stated at cost less amortization and are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Definite lived intangible assets include water rights, customer relationships, technology, non-compete agreements as well as licensing rights, which are being amortized using the straight-line method over their respective estimated useful lives. Any potential impairment for definite lived intangible assets will be calculated in the same manner as that disclosed under impairment of long-lived assets.
	Amortization is based mainly on the following useful lives:
			Useful life
	Water rights			40 years
	Customer relationships			10 to 40 years
	Technology			7 to 20 years
	Non-Compete agreements			9 years
	Licence rights			12 years
	OTHER ASSETS
	Other assets are recorded at cost. Direct financing costs related to the issuance of long-term debt are deferred and amortized using the effective interest rate method.
	ENVIRONMENTAL COSTS AND ASSET RETIREMENT OBLIGATIONS
	Environmental expenditures for effluent treatment, air emission, landfill operation and closure, asbestos containment and removal, bark pile management, silvicultural activities and site remediation (together referred to as environmental matters) are expensed or capitalized depending on their future economic benefit. In the normal course of business, Domtar Corporation incurs certain operating costs for environmental matters that are expensed as incurred. Expenditures for property, plant and equipment that prevent future environmental impacts are capitalized and amortized on a straight-line basis over 10 to 40 years. Provisions for environmental matters are not discounted, due to uncertainty with respect to timing of expenditures, and are recorded when remediation efforts are probable and can be reasonably estimated.
	Asset retirement obligations are recognized, at fair value, in the period in which Domtar Corporation incurs a legal obligation associated with the retirement of an asset. Conditional asset retirement obligations are recognized, at fair value, when the fair value of the liability can be reasonably estimated or on a probability-weighted discounted cash flow estimate. The associated costs are capitalized as part of the carrying value of the related asset and depreciated over its remaining useful life. The liability is accreted using the credit adjusted risk-free interest rate used to discount the cash flow.
	STOCK-BASED COMPENSATION AND OTHER STOCK-BASED PAYMENTS
	Domtar Corporation recognizes the cost of employee services received in exchange for awards of equity instruments over the requisite service period, based on their grant date fair value for awards accounted for as equity and based on the quoted market value of each reporting period for awards accounted for as liability. The Company awards are accounted for as compensation expense and presented in Additional paid-in-capital on the Consolidated Balance Sheets for equity type awards and presented in Other liabilities and deferred credits on the Consolidated Balance Sheets for liability type awards.
	The Company’s awards may be subject to market, performance and/or service conditions. Any consideration paid by plan participants on the exercise of stock options or the purchase of shares is credited to Additional paid-in-capital on the Consolidated Balance Sheets. The par value included in the Additional paid-in-capital component of stock-based compensation is transferred to Common shares upon the issuance of shares of common stock.
	Unless otherwise determined at the time of the grant, awards subject to service conditions vest in approximately equal installments over three years beginning on the first anniversary of the grant date and performance-based awards vest based on achievement of pre-determined performance goals over performance periods of three years. The majority of non-qualified stock options and performance share units expire at various dates no later than seven years from the date of grant. Deferred Share Units vest immediately at the grant date and are remeasured at each reporting period, until settlement, using the quoted market value.
	Under the 2007 Omnibus Incentive Plan (“Omnibus Plan”), a maximum of 2,394,415 shares are reserved for issuance in connection with awards granted or to be granted.
	DERIVATIVE INSTRUMENTS
	Derivative instruments are utilized by Domtar Corporation as part of the overall strategy to manage exposure to fluctuations in foreign currency, interest rate and commodity price on certain purchases. As a matter of policy, derivatives are not used for trading or speculative purposes. All derivatives are recorded at fair value either as assets or liabilities. When derivative instruments have been designated within a hedge relationship and are highly effective in offsetting the identified risk characteristics of specific financial assets and liabilities or group of financial assets and liabilities, hedge accounting is applied. In a fair value hedge, changes in fair value of derivatives are recognized in the Consolidated Statements of Earnings and Comprehensive Income. The change in fair value of the hedged item attributable to the hedged risk is also recorded in the Consolidated Statements of Earnings and Comprehensive Income by way of a corresponding adjustment of the carrying amount of the hedged item recognized in the Consolidated Balance Sheets. In a cash flow hedge, changes in fair value of derivative instruments are recorded in Other comprehensive (loss) income. These amounts are reclassified in the Consolidated Statements of Earnings and Comprehensive Income in the periods in which results are affected by the cash flows of the hedged item within the same line item. Any hedge ineffectiveness is recorded in the Consolidated Statements of Earnings and Comprehensive Income when incurred.
	PENSION PLANS
	Domtar Corporation’s plans include funded and unfunded defined benefit and defined contribution pension plans. Domtar Corporation recognizes the overfunded or underfunded status of defined benefit and underfunded defined contribution pension plans as an asset or liability in the Consolidated Balance Sheets. The net periodic benefit cost includes the following:
		•		The cost of pension benefits provided in exchange for employees’ services rendered during the period,
		•		The interest cost of pension obligations,
	•		The expected long-term return on pension fund assets based on a market value of pension fund assets,
	•		Gains or losses on settlements and curtailments,
	•		The straight-line amortization of past service costs and plan amendments over the average remaining service period of approximately 8 years of the active employee group covered by the plans, and
	•		The amortization of cumulative net actuarial gains and losses in excess of 10% of the greater of the accrued benefit obligation or market value of plan assets at the beginning of the year over the average remaining service period of approximately 8 years of the active employee group covered by the plans.
The defined benefit plan obligations are determined in accordance with the projected unit credit actuarial cost method.
OTHER POST-RETIREMENT BENEFIT PLANS
The Company recognizes the unfunded status of other post-retirement benefit plans (other than multiemployer plans) as a liability in the Consolidated Balance Sheets. These benefits, which are funded by Domtar Corporation as they become due, include life insurance programs, medical and dental benefits and short-term and long-term disability programs. The Company amortizes the cumulative net actuarial gains and losses in excess of 10% of the accrued benefit obligation at the beginning of the year over the average remaining service period of approximately 10 years of the active employee group covered by the plans.
BUSINESS COMBINATION
The Company applies the acquisition method of accounting in a business combination. In general, this methodology requires companies to record assets acquired and liabilities assumed at their respective fair market values at the date of acquisition. The value is determined from the viewpoint of market participants. Any amount of the purchase price paid that is in excess of the estimated fair values of net assets acquired is recorded in the line item goodwill in the consolidated balance sheets. Management’s judgment is used to determine the estimated fair values assigned to assets acquired and liabilities assumed, as well as asset useful lives for property, plant and equipment and amortization periods for intangible assets, and can materially affect the Company’s results of operations. Transaction costs, as well as costs to reorganize acquired companies, are expensed as incurred in the Company’s consolidated statement of income.
GUARANTEES
A guarantee is a contract or an indemnification agreement that contingently requires Domtar Corporation to make payments to the other party of the contract or agreement, based on changes in an underlying item that is related to an asset, a liability or an equity security of the other party or on a third party’s failure to perform under an obligating agreement. It could also be an indirect guarantee of the indebtedness of another party, even though the payment to the other party may not be based on changes in an underlying item that is related to an asset, a liability or an equity security of the other party. Guarantees, when applicable, are accounted for at fair value.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	NOTE 2.
	RECENT ACCOUNTING PRONOUNCEMENTS
	ACCOUNTING CHANGES IMPLEMENTED
	FOREIGN CURRENCY MATTERS
	In March 2013, the FASB issued ASU 2013-05, an update to Foreign Currency Matters, which indicates that a cumulative translation adjustment is attached to the parent’s investment in a foreign entity and should be released in a manner consistent with the derecognition guidance on investments in entities. Thus, the entire amount of the cumulative translation adjustment associated with the foreign entity would be released when there has been (1) a sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity; (2) a loss of a controlling financial interest in an investment in a foreign entity; or (3) a step acquisition for a foreign entity. The update does not change the requirement to release a pro rata portion of the cumulative translation adjustment of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity.
	The Company adopted the new requirement on January 1, 2014 with no impact on the Company’s consolidated financial statements, as no triggering event occurred throughout the period.
	INCOME TAXES
	In July 2013, the FASB issued ASU 2013-11, which provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This accounting standard update requires entities to assess whether or not to net the unrecognized tax benefit with a deferred tax asset as of the reporting date.
	The Company adopted the new requirement on January 1, 2014 with no material impact on the Company’s consolidated financial statements except for the change in presentation.
	PUSH DOWN ACCOUNTING
	In November 2014, the FASB issued ASU 2014-17, an update to business combinations and push down accounting. The amendments in this update provide an acquired entity with an option to apply pushdown in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply push down accounting in the reporting period in which the change in control event occurs.
	The Company adopted the new requirement on the effective date with no impact on the Company’s consolidated financial statements.
	FUTURE ACCOUNTING CHANGES
	DISCONTINUED OPERATIONS
	In April 2014, the FASB issued ASU 2014-08, an update on Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The amendments in this update change the requirements for reporting discontinued operations and require additional disclosures for both disposal transactions that meet the criteria for a discontinued operation and disposals that do not meet these criteria. The objective of this update is to reach a greater convergence between the FASB’s and IASB’s reporting requirements for discontinued operations.
	The amendments are effective for interim and annual periods beginning after December 15, 2014 and will not have an impact on the Company’s consolidated financial statements unless a disposal transaction occurs after the effective date. Early adoption is permitted.
	REVENUE FROM CONTRACTS WITH CUSTOMERS
	In May 2014, the FASB issued ASU 2014-09, an update on revenue from contracts with customers. The core principal of this guideline is that an entity should recognize revenue, to depict the transfer of promised goods or services to customers, in an amount that reflects the consideration for which the entity is entitled to, in exchange for those goods and services. Guidance in this section supersedes the revenue recognition requirements found in topic 605.
	The amendment will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently evaluating these changes to determine whether they have an impact on the presentation of the consolidated financial statements.
	STOCK COMPENSATION
	In June 2014, the FASB issued ASU 2014-12, an update on stock compensation. The guideline requires performance targets, which affect vesting and can be achieved after the requisite service period, to be treated as a performance condition. Accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If achievement of the performance target becomes probable before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period.
	The amendments are effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect these changes to have a material impact on the consolidated financial statements.
	GOING CONCERN
	In August 2014, the FASB issued ASU 2014-15, an update on going concern financial statements disclosure. The amendment requires the entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued.
	The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. This amendment is not expected to have an impact on the Company’s consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Impairment and Write-Down of Property, Plant and Equipment and Intangible Assets	NOTE 4.
	IMPAIRMENT AND WRITE-DOWN OF PROPERTY, PLANT AND EQUIPMENT AND INTANGIBLE ASSETS
	The Company reviews intangible assets and property, plant and equipment for impairment upon the occurrence of events or changes in circumstances indicating that, at the lowest level of determinable cash flows, the carrying value of the intangible and long-lived assets may not be recoverable.
	Estimates of undiscounted future cash flows used to test the recoverability of the fixed assets included key assumptions related to selling prices, inflation-adjusted cost projections, forecasted exchange rate for the U.S. dollar when applicable and the estimated useful life of the fixed assets.
	IMPAIRMENT OF PROPERTY, PLANT AND EQUIPMENT
	Ashdown, Arkansas pulp and paper mill—Conversion of a paper machine
	In the fourth quarter of 2014, the Company announced the conversion of a paper machine at Ashdown, Arkansas Pulp and Paper mill to a high quality fluff pulp line. As a result, the Company recognized $4 million of accelerated depreciation in the fourth quarter of 2014. An additional $108 million of accelerated depreciation is expected to be incurred during 2015 and 2016.
	Given the closure of the paper machine, the Company conducted a Step I impairment test on the Ashdown mill’s fixed assets and concluded that the undiscounted estimated future cash flows associated with the remaining long-lived assets exceeded their carrying amount.
	Changes in the assumptions and estimates may affect the Company’s forecasts and may lead to an outcome where impairment charges would be required. In addition, actual results may vary from the Company’s forecasts, and such variations may be material and unfavorable, thereby triggering the need for future impairment tests where the Company’s conclusions may differ in reflection of prevailing market conditions.
	Attends Europe
	During the fourth quarter of 2013, the Company recorded a $2 million write-down of property, plant and equipment, due to the replacement of certain equipment at its Attends Europe location, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Pulp and paper converting site
	During the fourth quarter of 2013, the Company recorded a $5 million write-down of property, plant and equipment in one of its converting sites in the pulp and paper segment, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Ariva U.S.
	On July 31, 2013, the Company completed the sale of its Ariva business in the United States (“Ariva U.S.”). Ariva U.S. had approximately 400 employees in the United States. As a result of this agreement, during the second quarter of 2013, the Company recorded a $5 million impairment of property, plant and equipment at its Ariva U.S. location, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Kamloops, British Columbia—Closure of a pulp machine
	On December 13, 2012, the Company announced the permanent shut down of one pulp machine at its Kamloops, British Columbia mill. This decision resulted in a permanent curtailment of Domtar’s annual pulp production by approximately 120,000 air dried metric tons of sawdust softwood pulp and affected approximately 125 employees. As a result, the Company recognized in 2012, $7 million of accelerated depreciation under Impairment and write-down of property, plant and equipment and intangible assets. The pulp machine ceased production in March 2013. Furthermore, during the first quarter of 2013, the Company recognized $10 million of accelerated depreciation under Impairment and write-down of property, plant and equipment and intangible assets. Given the decision to close the pulp machine, the Company assessed in the fourth quarter of 2012 its ability to recover the carrying value of the Kamloops mill from the undiscounted estimated future cash flows. The Company concluded that the undiscounted estimated future cash flows associated with the long-lived assets exceeded their carrying amount and, as such, no additional impairment charge was required.
	Mira Loma, California converting plant
	During the first quarter of 2012, the Company recorded a $2 million write-down of property, plant and equipment at its Mira Loma location, in Impairment and write-down of property, plant and equipment and intangible assets.
	IMPAIRMENT OF INTANGIBLE ASSETS
	Deterioration in sales and operating results of Ariva U.S., a subsidiary included in the Pulp and Paper segment, has led the Company to test the customer relationships of this asset group for recoverability. As of December 31, 2012, the Company recognized an impairment charge of $5 million included in Impairment and write-down of property, plant and equipment and intangible assets related to customer relationships based on the revised long-term forecast. The Company concluded that no further impairment or impairment indicators exist as of December 31, 2012.
	Changes in the assumptions and estimates may affect the Company’s forecasts and may lead to an outcome where impairment charges would be required. In addition, actual results may vary from the Company’s forecasts, and such variations may be material and unfavorable, thereby triggering the need for future impairment tests where the Company’s conclusions may differ in reflection of prevailing market conditions.

The Company generally grants awards annually and uses, when available, treasury stock to fulfill awards settled in common stock and option exercises.
	PERFORMANCE SHARE UNITS (“PSU’s”)
	PSUs are granted to Management Committee and non-Management Committee members. These awards will be settled in shares for Management Committee members and in cash equivalent to the share price for non-Management Committee members, based on market conditions and/or performance and service conditions. These awards have an additional feature where the ultimate number of units that vest will be determined by the Company’s performance results or shareholder return in relation to a predetermined target over the vesting period. No awards vest when the minimum thresholds are not achieved. The performance measurement date will vary depending on the specific award. These awards will cliff vest at various dates up to December 31, 2016.

	RSUs are granted to Management Committee and non-Management Committee members. These awards will be settled in shares for Management Committee members and in cash equivalent to the share price for non-Management Committee members, upon completing service conditions. The awards cliff vest after approximately a three year service period. Additionally, the RSUs are credited with dividend equivalents in the form of additional RSUs when cash dividends are paid on the Company’s stock. The grant date fair value of RSUs is equal to the market value of the Company’s stock on the date the awards are granted.

For Directors’ DSUs, the Company will deliver at the option of the holder either one share of common stock or the cash equivalent of the fair market value on settlement of each outstanding DSU (including dividend equivalents accumulated) upon termination of service. The grant date fair value of DSUs awards is equal to the market value of the Company’s stock on the date the awards are granted.
	Management committee members may elect to defer awards earned under another program into DSUs. In 2014, 6,799 vested awards were deferred to DSUs (2013 – 7,680), and those DSUs can be settled in shares of common stock beginning February 2017.

	NON-QUALIFIED & PERFORMANCE STOCK OPTIONS
	Stock options are granted to Management Committee and non-Management Committee members. The stock options vest at various dates up to May 1, 2017 subject to service conditions for non-qualified stock options and, for performance stock options, if certain market conditions are met in addition to the service period. The options expire at various dates no later than seven years from the date of grant.
	The fair value of the stock options granted in 2014 (except for the stock options granted on May 1, 2014) and 2013 was estimated at the grant date using a Black-Scholes based option pricing model or an option pricing model that incorporated the market conditions when applicable. The following assumptions were used in calculating the fair value of the options granted:
			2014			2013
	Dividend yield			2.62%			2.67%

	Expected life			4.5 years			4.5 years
	Strike price		$	53.12		$	38.35
	The grant date fair value of the non-qualified options granted in 2014, was $11.60 (2013 – $8.86).
	On May 1, 2014, the Company granted 29,002 options to Michael Garcia, President Pulp and Paper, as part of his employment conditions, and the following assumptions were used in calculating the fair value of the options granted:

In addition to the above noted outstanding options, the Company has 2,352 (2013 – 5,922) outstanding and exercisable stock appreciation rights at December 31, 2014 with a weighted average exercise price of $38.80 (2013 – $39.96).
The total intrinsic value of options exercised in 2014 was $2 million (2013 – $2 million). Based on the Company’s closing year-end stock price of $40.22, the aggregate intrinsic value of options outstanding and options exercisable is nil.
For the year ended December 31, 2014, stock-based compensation expense recognized in the Company’s results of operations was $9 million (2013 – $13 million; 2012 – $20 million) for all of the outstanding awards. Compensation costs not yet recognized amounted to $14 million (2013 – $11 million; 2012 – $12 million) and will be recognized over the remaining service period of approximately 28 months. The aggregate value of liability awards settled in 2014 was $12 million. The total fair value of equity awards settled in 2014 was $10 million, representing the fair value at the time of settlement. Compensation costs for performance awards are based on management’s best estimate of the final performance measurement.
CLAWBACK FOR FINANCIAL REPORTING MISCONDUCT
If a participant in the Omnibus Plan knowingly or grossly negligently engages in financial reporting misconduct, then all awards and gains from the exercise of options or stock appreciation rights in the 12 months prior to the date the misleading financial statements were issued as well as any awards that vested based on the misleading financial statements will be disgorged to the Company. In addition, the Company may cancel or reduce, or require a participant to forfeit and disgorge to the Company or reimburse the Company for, any awards granted or vested, and bonus granted or paid, and any gains earned or accrued, due to the exercise, vesting or settlement of awards or sale of any common stock, to the extent permitted or required by, or pursuant to any Corporation policy implemented as required by applicable law, regulation or stock exchange rule as may from time to time be in effect.

Earnings Per Share [Abstract]
Earnings Per Common Share	NOTE 6.
	EARNINGS PER COMMON SHARE
	On April 30, 2014, the Company’s Board of Directors approved a 2-for-1 split of its common stock to be effected through a stock dividend. Shareholders of record on June 10, 2014 were entitled to receive one additional share for every share they owned on that date.
	The calculation of basic earnings per common share for the year ended December 31, 2014 is based on the weighted average number of Domtar common shares outstanding during the year. The calculation for diluted earnings per common share recognizes the effect of all potential dilutive common securities.
	The following table provides the reconciliation between basic and diluted earnings per common share:
		Year ended		Year ended		Year ended

Compensation and Retirement Disclosure [Abstract]
Pension Plans and Other Post-Retirement Benefit Plans	NOTE 7.
	PENSION PLANS AND OTHER POST-RETIREMENT BENEFIT PLANS
	DEFINED CONTRIBUTION PLANS
	The Company has several defined contribution plans and multiemployer plans. The pension expense under these plans is equal to the Company’s contribution. For the year ended December 31, 2014, the related pension expense was $28 million (2013 – $29 million; 2012 – $24 million).
	DEFINED BENEFIT PLANS AND OTHER POST-RETIREMENT BENEFIT PLANS
	The Company sponsors both contributory and non-contributory U.S. and non-U.S. defined benefit pension plans. Non-unionized employees in Canada joining the Company after June 1, 2000 participate in a defined contribution pension plan. Salaried employees in the U.S. joining the Company after January 1, 2008 participate in a defined contribution pension plan. Most unionized employees in the U.S. and all U.S. non-hourly employees that are not grandfathered under the existing defined benefit pension plans, participate in a defined contribution pension plan for future service. The Company also sponsors a number of other post-retirement benefit plans for eligible U.S. and non-U.S. employees; the plans are unfunded and include life insurance programs and medical and dental benefits. The Company also provides supplemental unfunded defined benefit pension plans and supplemental unfunded defined contribution pension plans to certain senior management employees.
	Related pension and other post-retirement plan expenses and the corresponding obligations are actuarially determined using management’s most probable assumptions.
	The Company’s pension plan funding policy is to contribute annually the amount required to provide for benefits earned in the year, and to fund solvency deficiencies, funding shortfalls and past service obligations over periods not exceeding those permitted by the applicable regulatory authorities. Past service obligations primarily arise from improvements to plan benefits. The other post-retirement benefit plans are not funded and contributions are made annually to cover benefits payments.
	The Company expects to contribute a minimum total amount of $14 million in 2015 compared to $29 million in 2014 (2013 – $35 million; 2012 – $86 million) to the pension plans. The Company expects to contribute a minimum total amount of $5 million in 2015 compared to $5 million in 2014 to the other post-retirement benefit plans (2013 – $10 million; 2012 – $7 million).

	INVESTMENT POLICIES AND STRATEGIES OF THE PLAN ASSETS
	The assets of the pension plans are held by a number of independent trustees and are accounted for separately in the Company’s pension funds. The investment strategy for the assets in the pension plans is to maintain a diversified portfolio of assets, invested in a prudent manner to maintain the security of funds while maximizing returns within the guidelines provided in the investment policy. Diversification of the pension plans’ holdings is maintained in order to reduce the pension plans’ annual return variability, reduce market and credit exposure to any single issuer and to any single component of the capital markets, reduce exposure to unexpected inflation, enhance the long-term risk-adjusted return potential of the pension plans and reduce funding risk.
	Over the long-term, the performance of the pension plans is primarily determined by the long-term asset mix decisions. To manage the long-term risk of not having sufficient funds to match the obligations of the pension plans, the Company conducts asset/liability studies. These studies lead to the recommendation and adoption of a long-term asset mix target that sets the expected rate of return and reduces the risk of adverse consequences to the plans from increases in liabilities and decreases in assets. In identifying the asset mix target that would best meet the investment objectives, consideration is given to various factors, including (a) each plan’s characteristics, (b) the duration of each plan’s liabilities, (c) the solvency and going concern financial position of each plan and their sensitivity to changes in interest rates and inflation, and (d) the long-term return and risk expectations for key asset classes.
	The investments of each plan can be done directly through cash investments in equities or bonds or indirectly through derivatives or pooled funds. The use of derivatives must be in accordance with an approved mandate and cannot be used for speculative purposes.
	The Company’s pension funds are not permitted to directly own any of the Company’s shares or debt instruments.
	The following table shows the allocation of the plan assets, based on the fair value of the assets held and the target allocation for 2014:
			Target			Percentage of			Percentage of
			allocation			plan assets at			plan assets at
						December 31,			December 31,

(b)	The settlement loss of $19 million in the pension plans for the year ended December 31, 2014 is related to the previously closed Ottawa, Ontario paper mill. The settlement loss of $13 million in the pension plans for the year ended December 31, 2013 is related to the previously closed Big River and Dryden mills for $6 million and $7 million, respectively (see Note 16 “Closure and restructuring costs and liability”). The settlement loss for the year ended December 31, 2012 of $1 million is related to the sale of hydro assets in Ottawa, Ontario and Gatineau, Quebec.
(c)	The curtailment gain of $12 million for the year ended December 31, 2012 is a result of the curtailment of benefits related to the majority of employees covered by the plan.
WEIGHTED-AVERAGE ASSUMPTIONS
The Company used the following key assumptions to measure the accrued benefit obligation and the net periodic benefit cost. These assumptions are long-term, which is consistent with the nature of employee future benefits.
Pension plans		December 31,			December 31,			December 31,
		2014			2013			2012
Accrued benefit obligation
Discount rate			3.9	%		4.1	%		4.1	%
Rate of compensation increase			2.7	%		2.7	%		2.7	%
Net periodic benefit cost
Discount rate			4.7	%		4.2	%		4.8	%
Rate of compensation increase			2.7	%		2.8	%		2.8	%
Expected long-term rate of return on plan assets			6.4	%		5.8	%		6	%
Discount rate for Canadian plans: 3.9% based on a model whereby cash flows are projected for hypothetical plans and are discounted using a spot rate yield curve developed from bond yield data for AA corporate bonds. Specifically, short-term yields to maturity are derived from actual AA rated corporate bond yield data. For longer terms, extrapolated data is used. The extrapolated data are created by adding a term-based spread over long provincial bond yields. The spread is based on the observed spreads between AA rated corporate bonds and AA rated provincial bonds in three sections of the yield curve.
Discount rate for U.S. plans: 3.85% obtained by incorporating the Company’s qualified plans’ expected cash flows in the Mercer Yield Curve which is based on bonds rated AA or better by Moody’s or Standard & Poor’s, excluding callable bonds, bonds of less than a minimum issue size, and certain other bonds. Effective December 2012, the universe of bonds also includes private placement (traded in reliance on Rule 144A and with at least two years to maturity), make whole, and foreign corporation (denominated in US dollars) bonds.
Effective January 1, 2015, the Company will use 5.6% (2014 – 6.4%; 2013 – 5.8%) as the expected return on plan assets, which reflects the current view of long-term investment returns. The overall expected long-term rate of return on plan assets is based on management’s best estimate of the long-term returns of the major asset classes (cash and cash equivalents, equities, and bonds) weighted by the actual allocation of assets at the measurement date, net of expenses. This rate includes an equity risk premium over government bond returns for equity investments and a value-added premium for the contribution to returns from active management. The sources used to determine management’s best estimate of long-term returns are numerous and include country specific bond yields, which may be derived from the market using local bond indices or by analysis of the local bond market, and country-specific inflation and investment market expectations derived from market data and analysts’ or governments’ expectations as applicable.
Other post-retirement benefit plans		December 31,			December 31,			December 31,
		2014			2013			2012
Accrued benefit obligation
Discount rate			3.9	%		4.8	%		4.2	%
Rate of compensation increase			2.8	%		2.8	%		2.8	%
Net periodic benefit cost
Discount rate			4.8	%		4.2	%		2.9	%
Rate of compensation increase			2.7	%		2.8	%		2.8	%
For measurement purposes, a 5.2% weighted average annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014. The rate was assumed to decrease gradually to 4.1% by 2033 and remain at that level thereafter. An increase or decrease of 1% of this rate would have the following impact:
		Increase of 1%		Decrease of 1%
		$		$
Impact on net periodic benefit cost for other post-retirement benefit plans		1		-1
Impact on accrued benefit obligation		9		-8
FAIR VALUE MEASUREMENT
Fair Value Measurements and Disclosures Topic of FASB ASC 820 establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three levels. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is available and significant to the fair value measurement.
Level 1		Quoted prices in active markets for identical assets or liabilities.
Level 2		Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3		Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the assets or liabilities.
The following table presents the fair value of the plan assets at December 31, 2014, by asset category:

ASSET BACKED NOTES
At December 31, 2014, Domtar Corporation’s Canadian defined benefit pension funds held restructured asset backed notes (“ABN”) (formerly asset backed commercial paper) valued at $180 million (CDN $209 million). At December 31, 2013, the plans held ABN valued at $203 million (CDN $216 million). During 2014, the total value of the ABN benefited from an increase in value of $18 million (CDN $20 million). For the same period, the total value of ABN was reduced by repayments and sales totalling $24 million (CDN $27 million), and by a $17 million impact of a decrease in the value of the Canadian dollar.
Most of these ABN, with a current value of $171 million (2012 and 2013, respectively – $193 million), were subject to restructuring under the court order governing the Montreal Accord that was completed in January 2009. About $165 million of these notes are expected to mature in two years. These notes are valued based upon current market quotes and auction results. The market values are supported by the value of the underlying investments held by the issuing conduit. The values for the $6 million of remaining ABN, that also were subject to the Montreal Accord, were sourced either from the asset manager of the ABN, or from trading values for similar securities of similar credit quality.
An additional $9 million of ABN were restructured separately from the Montreal Accord. They are valued based upon the value of the collateral investments held in the conduit issuer, reduced by the negative value of credit default derivatives, with an additional discount (equivalent 1.75% per annum) applied for illiquidity. They are expected to mature in two years.
Possible changes that could impact the future value of ABN include: (1) changes in the value of the underlying assets and the related derivative transactions, (2) developments related to the liquidity of the ABN market, (3) a severe and prolonged economic slowdown in North America and the bankruptcy of referenced corporate credits, and (4) the passage of time, as most of the notes will mature in approximately two years.

MULTIEMPLOYER PLANS
Domtar contributed to seven multiemployer defined benefit pension plans under the terms of collective agreements that cover certain Canadian and U.S. unionized employees. As of December 31, 2014, the Company had withdrawn from all five U.S. multiemployer plans, and continued to participate in the two Canadian plans. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:
	(a)	assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers;
	(b)	for the U.S. multiemployer plans, if a participating employer stops contributing to the plan, the unfunded obligations of the plan are borne by the remaining participating employers; and
	(c)	for the U.S. multiemployer plans, if Domtar chooses to stop participating in some of its multiemployer plans, Domtar may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
Domtar’s participation in these plans for the annual periods ended December 31 is outlined in the table below. The plan’s 2014, 2013 and 2012 actuarial status certification was completed as of January 1, 2014, January 1, 2013 and January 1, 2012, respectively, and is based on the plan’s actuarial valuation as of December 31, 2013, December 31, 2012 and December 31, 2011, respectively. This represents the most recent Pension Protection Act zone status available. The zone status is based on information received from the plan and is certified by the plan’s actuary.

(a)	Domtar withdrew from PACE Industry Union-Management Pension Fund effective December 31, 2012.
(b)	In the event that the Canadian multiemployer plan is underfunded, the monthly benefit amount can be reduced by the trustees of the plan. Moreover, Domtar is not responsible for the underfunded status of the plan because the Canadian multiemployer plans do not require participating employers to pay a withdrawal liability or penalty upon withdrawal.
(c)	For each of the three years presented, Domtar’s contributions to each multiemployer plan do not represent more than 5% of total contributions to each plan as indicated in the plan’s most recently available annual report.
(d)	On July 31, 2013, Domtar withdrew from all remaining U.S. multiemployer plans.
In relation to the withdrawal from one of the Company’s multiemployer pension plans in 2011, the Company recorded an additional charge to earnings of $1 million due to a change in the estimated withdrawal liability during the first quarter of 2013. During the second and third quarter of 2013, the Company withdrew from its remaining U.S. multiemployer pension plans and recorded a withdrawal liability and a charge to earnings of $14 million, of which $3 million is recorded in Closure and restructuring costs and $11 million related to the sale of its Ariva U.S. business included in Other operating (income) loss, net on the Consolidated Statement of Earnings and Comprehensive Income. At December 31, 2014, the total provision for the withdrawal liabilities is $60 million. While this is the Company’s best estimate of the ultimate cost of the withdrawal from these plans at December 31, 2014, additional withdrawal liabilities may be incurred based on the final fund assessment and in the event of a mass withdrawal, as defined by statute, occurring anytime within the next two years (See Note 16 “Closure and Restructuring Costs and Liability”).

	-2	On March 22, 2013, the Company sold the building, remaining equipment and related land of the closed pulp and paper mill in Port Edwards, Wisconsin and recorded a gain on the sale of approximately $10 million. The transaction included specific machinery, equipment, furniture, parts, supplies, tools, real estate, land improvements, and other fixed or tangible assets. The assets were sold “as is” for proceeds of approximately $9 million and the environmental provision of $3 million related to these assets was contractually passed on to the buyer and released from the Company’s liabilities. The net book value of the assets sold was approximately $2 million. In November 2013, the Company sold its land in Cornwall, Ontario and recorded a gain on the sale of approximately $6 million.
	On November 20, 2012, the Company sold its hydro assets in Ottawa, Ontario and Gatineau, Quebec for approximately $46 million (CDN $46 million) and included three power stations (21M megawatts of installed capacity), water rights in the area, as well as Domtar Inc.’s equity stake in the Chaudière Water Power Inc., a ring dam consortium. As a result, the Company incurred a loss relating to the curtailment of the pension plan of $2 million and legal fees of $1 million.
	-3	On June 24, 2013, the parties agreed to settle the Weston litigation for a payment by Domtar to Weston of $49 million (CDN $50 million).

	In 2014, the IRS completed its ongoing U.S. federal income tax audit for tax years 2009, 2010, and 2011, and the Company filed related amended state tax returns. As a result of the audit completion, the Company recognized previously unrecognized gross tax benefits of $223 million and reversed related deferred tax assets of $23 million for a net tax benefit of $200 million for 2014. This $200 million benefit, less $6 million of expense for other 2014 activity, impacted the 2014 effective tax rate and is included in the table above in the Uncertain tax positions benefit of $194 million. The audit closure also resulted in an additional $7 million benefit related to the U.S. manufacturing deduction which impacted the effective tax rate for 2014 and is included in the $9 million for that line item above. The effective tax rate was also impacted by the recognition of $18 million of Alternative Fuel Tax Credits (“AFTC”) with no related tax expense. During 2014, the Company recorded $18 million of tax credits, mainly research and experimentation credits pertaining to current and prior years. The effective tax rate for 2014 was also significantly impacted by an enacted tax rate decrease in Spain and tax losses related to functional currency differences.
	During 2013, the Company recorded $54 million of various tax credits pertaining to current and prior years. These credits included the conversion of $26 million of AFTC into $55 million of Cellulosic Biofuel Producer Credits (“CBPC”) resulting in an after-tax benefit of $33 million for the new credit, as well as research and experimentation credits and other federal and state credits. Also, the Company’s effective tax rate is being reduced in 2013 by the impact of the U.S. manufacturing deduction and enacted law changes in certain states and provinces. The effective tax rate is being increased by the impact of certain non-deductible payments, mainly the Weston litigation settlement and the AFTC repayment, and an increase in the valuation allowance on certain losses. Additionally, the effective tax rate is being impacted by an $8 million reduction in unrecognized tax benefits pertaining to the AFTC which was converted to CBPC, partially offset by $5 million of accrued interest on uncertain tax positions.
	The Company recognized a tax benefit of $10 million for the manufacturing deduction in the U.S. in 2012 which impacted the effective tax rate for 2012. Additionally, the Company recorded an $8 million tax benefit related to federal, state, and provincial credits and special deductions which reduced the effective rate. The effective tax rate for 2012 was also impacted by an increase in the Company’s unrecognized tax benefits of $6 million, mainly accrued interest, and a $3 million benefit related to enacted tax law changes, mainly a tax rate reduction in Sweden, which was partially offset by U.S. tax law changes in several states.
	Deferred tax assets and liabilities are based on tax rates that are expected to be in effect in future periods when deferred items are expected to reverse. Changes in tax rates or tax laws affect the expected future benefit or expense. The effect of such changes that occurred during each of the last three fiscal years is included in “Tax rate changes” disclosed under the effective income tax rate reconciliation shown above.
	ALTERNATIVE FUEL TAX CREDITS
	As of December 31, 2014, the Company has no remaining gross unrecognized tax benefits and interest or related deferred tax assets associated with the AFTC claimed on its 2009 tax return. These benefits amounting to $198 million were recognized, reduced by the reversal of related deferred tax assets of $20 million, or $178 million net of deferred taxes, during 2014, thus impacting the effective tax rate.
	DEFERRED TAX ASSETS AND LIABILITIES
	The tax effects of significant temporary differences representing deferred tax assets and liabilities at December 31, 2014 and December 31, 2013 are comprised of the following:

With the acquisition of AHP on July 1, 2013, and Attends US on September 1, 2011, the Company acquired additional federal net operating loss carryforwards of $48 million and $2 million, respectively. These U.S. federal net operating losses are subject to annual limitations under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), that can vary from year to year. At December 31, 2014, the Company had $6 million of federal net operating loss carryforward remaining which expires in 2032. Canadian scientific research and experimental development expenditures not previously deducted represent an amount of $99 million. The Canadian federal losses have been fully utilized as of December 31, 2014, and there is no expiration date on the scientific research and experimental development expenditures. The Company also has other foreign net operating loss carryforwards of $23 million, of which $5 million will begin to expire in 2017, $76 million, which may be carried forward indefinitely, and $11 million of finance expenditures not previously deducted.
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible.
The Company evaluates the realization of deferred tax assets on a quarterly basis. Evaluating the need for an amount of a valuation allowance for deferred tax assets often requires significant judgment. All available evidence, both positive and negative, is considered when determining whether, based on the weight of that evidence, a valuation allowance is needed. Specifically, we evaluated the following items:
	•		Historical income / (losses)—particularly the most recent three-year period
	•		Reversals of future taxable temporary differences
	•		Projected future income / (losses)
	•		Tax planning strategies
	•		Divestitures
Management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets in the U.S., with the exception of certain state credits for which a valuation allowance of $4 million exists at December 31, 2014, and certain foreign loss carryforwards for which a valuation allowance of $21 million exists at December 31, 2014. Of this amount, $7 million impacted tax expense and the effective tax rate for 2014 ($5 million – 2013; $1 million – 2012).
The Company does not provide for a U.S. income tax liability on undistributed earnings of our foreign subsidiaries. The earnings of the foreign subsidiaries, which reflect full provision for income taxes, are currently indefinitely reinvested in foreign operations. No provision is made for income taxes that would be payable upon the distribution of earnings from foreign subsidiaries as computation of these amounts is not practicable.
ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES
At December 31, 2014, the Company had gross unrecognized tax benefits of approximately $48 million ($259 million and $254 million for 2013 and 2012 respectively). If recognized in 2015, these tax benefits would impact the effective tax rate. These amounts represent the gross amount of exposure in individual jurisdictions and do not reflect any additional benefits expected to be realized if such positions were sustained, such as federal deduction that could be realized if an unrecognized state deduction was not sustained.

As a result of the acquisition of Indas on January 2, 2014 and AHP on July 1, 2013, the Company recorded unrecognized tax benefits which are shown as additions for tax positions of prior years in the table above.
The Company recorded $4 million of accrued interest associated with unrecognized tax benefits for the period ending December 31, 2014 ($5 million and $9 million for 2013 and 2012, respectively). The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits as a component of tax expense.
The major jurisdictions where the Company and its subsidiaries will file tax returns for 2014, in addition to filing one consolidated U.S. federal income tax return, are Canada, Sweden, and Spain. The Company and its subsidiaries will also file returns in various other countries in Europe and Asia as well as various states and provinces. At December 31, 2014, the Company’s subsidiaries are subject to foreign federal income tax examinations for the tax years 2007 through 2012, with federal years prior to 2009 being closed from a cash tax liability standpoint in the U.S., but the loss carryforwards can be adjusted in any open year where the loss has been utilized. The Company does not anticipate that adjustments stemming from these audits would result in a significant change to the results of its operations and financial condition, except as mentioned below.
During the third quarter of 2014, the IRS completed an audit of the Company’s 2009, 2010, and 2011 U.S. income tax returns. As a result of the audit closure, the Company recognized previously unrecognized gross tax benefits of $223 million and reversed related deferred tax assets of $23 million for a net tax benefit of $200 million for 2014. The recognition of these benefits, $200 million net of deferred taxes, impacted the effective tax rate for 2014. Included in the above amounts are previously unrecognized tax benefits and interest of $198 million and the reversal of related deferred assets (expense) of $20 million, a $178 million benefit net of deferred taxes, related to AFTC. As of December 31, 2014, the Company has no remaining gross unrecognized tax benefits and interest or related deferred tax assets associated with the AFTC claimed on its 2009 tax return.

	The Company performed its annual goodwill impairment testing at October 1, 2014 and 2013 and determined that the estimated fair value of the reporting units exceeded their carrying values. On October 1, 2012, the Company assessed qualitative factors to determine whether it was more likely than not that the fair value of the reporting unit was less than its carrying amount. After assessing the totality of events and circumstances, the Company determined that it was more likely than not that the fair value of the reporting unit was greater than its carrying amount. As a result, no impairment charges were recorded during 2014, 2013 or 2012.

Restructuring and Related Activities [Abstract]
Closure and Restructuring Costs and Liability	NOTE 16.
	CLOSURE AND RESTRUCTURING COSTS AND LIABILITY
	The Company regularly reviews its overall production capacity with the objective of aligning its production capacity with anticipated long-term demand, which in some cases could result in closure or impairment costs being recorded in earnings.
	In relation to the withdrawal from one of the Company’s multiemployer pension plans in 2011, the Company recorded a charge to earnings of $14 million in 2012, as a result of a revision in the estimated withdrawal liability. Also in 2012, the Company withdrew from a second multiemployer pension plan and recorded a withdrawal liability and a charge to earnings of $1 million. In the first quarter of 2013, as a result of another revision in the estimated withdrawal liability, the Company recorded a further charge to earnings of $1 million. During the second and third quarter of 2013, the Company withdrew from its remaining U.S. multiemployer pension plans and recorded a withdrawal liability and a charge to earnings of $14 million, of which $3 million is recorded in Closure and restructuring costs and $11 million related to the sale of its Ariva U.S. business in Other operating (income) loss, net on the Consolidated Statement of Earnings and Comprehensive Income. At December 31, 2014, the total provision for the withdrawal liabilities is $60 million. At December 31, 2014, this is the Company’s best estimate of the ultimate cost of the withdrawal from these plans. Further, the Company remains liable for potential additional withdrawal liabilities to the fund in the event of a mass withdrawal, as defined by statute, occurring anytime up to the next two years.
	During the fourth quarter of 2014, the Company incurred pension settlement costs in the amount of $19 million related to the previously closed Ottawa paper mill.
	During the second quarter of 2013, the Company incurred pension settlement costs in the amount of $13 million related to the previously closed Big River sawmill and Dryden paper mill for $6 million and $7 million, respectively.
	Ashdown, Arkansas mill
	On December 10, 2014, the Company announced that its Board of Directors has approved a $160 million capital project to convert a paper machine at the Ashdown, Arkansas mill to a high quality fluff pulp line used in absorbent applications such as baby diapers, feminine hygiene and adult incontinence products. The planned conversion is expected to come online by the third quarter 2016 and will allow for the production of up to 516,000 metric tons of fluff pulp per year once the machine is in full operation. The project will also result in the permanent reduction of 364,000 short tons of annual uncoated freesheet production capacity in the second quarter of 2016.
	The conversion work is expected to commence during the second quarter of 2016 and the fluff pulp line is scheduled to startup by the third quarter 2016. The cost of conversion will be approximately $160 million of which $40 million is expected to be invested in 2015 and $120 million in 2016. The Company will also invest $40 million in a pulp bale line that will provide flexibility to manufacture papergrade softwood pulp, contingent on market conditions.
	The aggregate pre-tax earnings charge in connection with this conversion is estimated to be $120 million which includes an estimated $117 million in non-cash charges relating to accelerated depreciation of the carrying amounts of the manufacturing equipment as well as the write-off of related spare parts. Of the estimated pre-tax charge of $120 million, $3 million relates to estimated cash severance, employee benefits and training. Of the estimated total pre-tax charge of $120 million, $113 million is expected to be incurred during 2015 and 2016. As a result of the fourth quarter decision to convert a paper machine to a fluff pulp line at its Ashdown, Arkansas mill, the Company recorded in the fourth quarter of 2014 $4 million of accelerated depreciation under Impairment and write-down of property, plant and equipment on the Consolidated Statement of Earnings and Comprehensive Income and $3 million of inventory obsolescence under closure and restructuring costs.
	Indianapolis, Indiana Converting
	On October 13, 2014, the Company announced the closure of its Indianapolis, Indiana plant and the shutdown affected approximately 60 employees. As a result, during the fourth quarter of 2014, the Company recorded $2 million of closure and termination costs and $1 million of inventory obsolescence.
	Attends Europe
	During the fourth quarter of 2013, the Company recorded a $2 million write-down of property, plant and equipment due to the replacement of certain equipment at its Attends Europe location, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Pulp and paper converting site
	During the fourth quarter of 2013, the Company recorded a $5 million write-down of property, plant and equipment at one of its converting sites in the pulp and paper segment, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Ariva U.S.
	On July 31, 2013, the Company completed the sale of its Ariva U.S. business which had approximately 400 employees in the United States. As a result of this agreement, during the second quarter of 2013, the Company recorded a $5 million impairment of property, plant and equipment at its Ariva U.S. location, in Impairment and write-down of property, plant and equipment on the Consolidated Statement of Earnings and Comprehensive Income.
	Kamloops, British Columbia pulp facility
	On December 13, 2012, the Company announced the permanent shut down of one pulp machine at its Kamloops, British Columbia mill. This decision resulted in a permanent curtailment of Domtar’s annual pulp production by approximately 120,000 air dried metric tons of sawdust softwood pulp and affected approximately 125 employees.
	As a result, the Company recognized in 2012, $7 million of accelerated depreciation under Impairment and write-down of property, plant and equipment and intangibles assets, $5 million of severance and termination costs and a $4 million write-down of inventory. The pulp machine ceased production in March 2013. Furthermore, during the first quarter of 2013, the Company recognized $10 million of accelerated depreciation under Impairment and write-down of property, plant and equipment, and reversed $1 million of severance and termination costs. During the second quarter of 2013, the Company reversed an additional $1 million of severance and termination costs, reversed $1 million of inventory obsolescence, and incurred $2 million of other costs.
	Mira Loma, California converting plant
	During the first quarter of 2012, the Company recorded a $2 million write-down of property, plant and equipment at its Mira Loma location in California, in Impairment and write-down of property, plant and equipment and intangible assets on the Consolidated Statement of Earnings and Comprehensive Income.
	Lebel-sur-Quévillon pulp mill and sawmill
	Operations at the pulp were indefinitely idled in November 2005 due to unfavorable economic conditions and the sawmill was indefinitely idled since 2006 and then permanently closed in 2008. At the time, the pulp mill and sawmill employed approximately 425 and 140 employees, respectively. The Lebel-sur-Quévillon pulp mill had an annual production capacity of 300,000 metric tons. During the second quarter of 2012, the Company concluded the sale of its pulp and sawmill assets to Fortress Paper Ltd., and its land related to those assets to a subsidiary of the Government of Quebec for net proceeds of $1.
	Other costs
	During 2014, other costs related to previous and ongoing closures include $3 million of severance and termination costs.
	During 2013, other costs related to previous and ongoing closures include $2 million of severance and termination costs.
	During 2012, other costs related to previous and ongoing closures include $1 million in severance and termination costs, a $1 million write-down of inventory, $1 million in pension and $3 million in other costs.

Closure and restructuring costs are based on management’s best estimates at December 31, 2014. Actual costs may differ from these estimates due to subsequent developments such as the results of environmental studies, the ability to find a buyer for assets set to be dismantled and demolished and other business developments. As such, additional costs and further write-downs may be required in future periods.

	UNSECURED NOTES
	During the first quarter of 2013, the Company redeemed its outstanding 5.375% Notes due 2013, for par value of $71 million. The Company incurred $2 million of premiums paid and additional charges of $1 million, included in Interest expense, net on the Consolidated Statement of Earnings and Comprehensive Income. The Company also repaid $23 million of capital lease obligations to purchase the land and buildings, related to the Greenville, North Carolina site, in the Personal Care segment.
	As a result of a cash tender offer during the first quarter of 2012, the Company repurchased $1 million of the 5.375% Notes due 2013, $47 million of the 7.125% Notes due 2015, $31 million of the 9.5% Notes due 2016 and $107 million of the 10.75% Notes due 2017. The Company incurred tender premiums of $47 million and additional charges of $3 million as a result of this extinguishment, both of which were included in Interest expense, net on the Consolidated Statements of Earnings and Comprehensive Income.
	SENIOR NOTES OFFERING
	On November 30, 2013, the Company issued $250 million 6.75% Notes due 2044 for net proceeds of $249 million. The net proceeds from the offering were used to fund a portion of the purchase price of the acquisition of Indas.
	On August 20, 2012, the Company issued $250 million 6.25% Notes due 2042 for net proceeds of $247 million. The net proceeds from the offering of the Notes were used for general corporate purposes.
	On March 7, 2012, the Company issued $300 million 4.4% Notes due 2022 for net proceeds of $297 million. The net proceeds from the offering of the Notes were used to fund the portion of the purchase of the 5.375% Notes due 2013, 7.125% Notes due 2015, 9.5% Notes due 2016 and 10.75% Notes due 2017 tendered and accepted by the Company pursuant to a tender offer, including the payment of accrued interest and applicable early tender premiums, not funded with cash on hand, as well as for general corporate purposes.
	The Notes are redeemable, in whole or in part, at the Company’s option at any time. In the event of a change in control, each holder will have the right to require the Company to repurchase all or any part of such holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes, plus any accrued and unpaid interest. The Notes are unsecured obligations and rank equally with existing and future unsecured and unsubordinated indebtedness. The Notes are fully and unconditionally guaranteed on an unsecured basis by certain U.S. 100% owned subsidiaries, which currently guarantee indebtedness under the Credit Agreement.
	BANK FACILITY
	On October 3, 2014, the Company entered into a $600 million amended and restated Credit Agreement that matures on October 3, 2019. This amended credit facility was scheduled to mature June 15, 2017. The Credit Agreement provides for a revolving credit facility (including a letter of credit sub-facility and a swingline sub-facility), which may be borrowed in U.S. Dollars, Canadian Dollars (in an amount up to the Canadian Dollar equivalent of $150 million) and Euros (in an amount up to the Euro equivalent of $200 million). The Company may increase the maximum aggregate amount of availability under the Credit Agreement by up to $400 million, borrow this increased amount as a term loan, and extend the final maturity of the Credit Agreement by one year, subject to the agreement of applicable lenders.
	Borrowings under the Credit Agreement bear interest at LIBOR, EURIBOR, Canadian bankers’ acceptance or prime rate, as applicable, plus a margin linked to a credit rating at the time of borrowing. In addition, the Company pays facility fees quarterly at rates dependent on the Company’s credit ratings.
	The Credit Agreement contains customary covenants, including two financial covenants: (i) an interest coverage ratio, as defined in the Credit Agreement, that must be maintained at a level of not less than 3 to 1 and (ii) a leverage ratio, as defined in the Credit Agreement that must be maintained at a level of not greater than 3.75 to 1. At December 31, 2014, the Company was in compliance with the covenants, and no amounts were borrowed (December 31, 2013 – $160 million). At December 31, 2014, the Company had no outstanding letters of credit under this credit facility (December 31, 2013 – $1 million).
	All borrowings under the Credit Agreement are unsecured. However, certain domestic subsidiaries of the Company unconditionally guarantee any obligations from time to time arising under the Credit Agreement, and certain subsidiaries of the Company that are not organized in the United States unconditionally guarantee any obligations of Domtar Inc., the Canadian subsidiary borrower, or of additional borrowers that are not organized in the United States, under the Credit Agreement, in each case, subject to the provisions of the Credit Agreement.
	RECEIVABLES SECURITIZATION
	The Company uses securitization of certain receivables to provide additional liquidity to fund its operations. The costs under the program may vary based on changes in interest rates. The Company’s securitization program consists of the ongoing sale of most of the receivables of its domestic subsidiaries to a bankruptcy remote consolidated subsidiary which, in turn, transfers a senior beneficial interest in them to a special purpose entity managed by a financial institution for multiple sellers of receivables to support the issue of letters of credit or borrowings.
	The program contains certain termination events, which include, but are not limited to, matters related to receivable performance, certain defaults occurring under the credit facility, or the failure by Domtar to satisfy material obligations.
	At December 31, 2014, the Company had no borrowings and $45 million of letters of credit outstanding under the program (2013 – nil and $46 million, respectively). Sales of receivables under this program are accounted for as secured borrowings.
	In 2014, a net charge of $1 million (2013 – $1 million; 2012 – $1 million) resulted from the program described above and was included in Interest expense in the Consolidated Statements of Earnings and Comprehensive Income.

	ASSET RETIREMENT OBLIGATIONS
	The asset retirement obligations are principally linked to landfill capping obligations, asbestos removal obligations and demolition of certain abandoned buildings. At December 31, 2014, Domtar estimated the net present value of its asset retirement obligations to be $20 million (2013 – $21 million); the present value is based on probability weighted undiscounted cash outflows of $64 million (2013 – $66 million). The majority of the asset retirement obligations are estimated to be settled prior to December 31, 2033. However, some settlement scenarios call for obligations to be settled as late as December 31, 2053. Domtar’s credit adjusted risk-free rates were used to calculate the net present value of the asset retirement obligations. The rates used vary between 5.5% and 12.0%, based on the prevailing rate at the moment of recognition of the liability and on its settlement period.

Equity [Abstract]
Shareholders' Equity	NOTE 21.
	SHAREHOLDERS’ EQUITY
	On April 30, 2014, the Company’s Board of Directors approved a 2-for-1 split of its common stock to be effected through a stock dividend. Shareholders of record on June 10, 2014 received one additional share for every share they owned on that date. As a result of the stock split, total shares of the Company’s common stock outstanding increased from approximately 32.5 million to 65 million.
	In addition, the Company’s Board of Directors approved an increase in the quarterly dividend on its common stock on a post-split basis, from $0.275 to $0.375 per share. This is equivalent to, on a pre-split basis, an increase of $0.20 per share (36%) per quarter.
	During 2014, the Company declared one quarterly dividend of $0.275 per share to holders of the Company’s common stock, as well as holders of exchangeable shares of Domtar (Canada) Paper Inc and three quarterly dividends of $0.375 per share, to holders of the Company’s common stock. The total dividends of approximately $18 million, $24 million, $24 million and $24 million were paid on April 15, 2014, July 15, 2014, October 15, 2014 and January 15, 2015, respectively, to shareholders of record as of March 14, 2014, July 2, 2014, October 2, 2014 and January 2, 2015, respectively.
	During 2013, the Company declared one quarterly dividend of $0.225 per share, on a post-split basis, and three quarterly dividends of $0.275 per share, on a post-split basis, to holders of the Company’s common stock, as well as holders of exchangeable shares of Domtar (Canada) Paper Inc. The total dividends of approximately $15 million, $19 million, $18 million and $17 million were paid on April 15, 2013, July 15, 2013, October 15, 2013 and January 15, 2014, respectively, to shareholders of record as of March 15, 2013, June 14, 2013, September 13, 2013 and December 13, 2013, respectively.
	On February 23, 2015, the Company’s Board of Directors approved a quarterly dividend of $0.40 per share to be paid to holders of the Company’s common stock. This dividend is to be paid on April 15, 2015 to shareholders of record on April 2, 2015.
	STOCK REPURCHASE PROGRAM
	In 2010, the Company’s Board of Directors authorized a stock repurchase program (“the Program”) of up to $1 billion of Domtar Corporation’s common stock. On February 23, 2015, the Company’s Board of Directors approved an increase to the Program from $1 billion to $1.3 billion. Under the Program, the Company is authorized to repurchase from time to time shares of its outstanding common stock on the open market or in privately negotiated transactions in the United States. The timing and amount of stock repurchases will depend on a variety of factors, including the market conditions as well as corporate and regulatory considerations. The Program may be suspended, modified or discontinued at any time and the Company has no obligation to repurchase any amount of its common stock under the Program. The Program has no set expiration date. The Company repurchases its common stock, from time to time, in part to reduce the dilutive effects of stock options, awards, and to improve shareholders’ returns.
	The Company makes open market purchases of its common stock using general corporate funds. Additionally, the Company enters into structured stock repurchase agreements with large financial institutions using general corporate funds in order to lower the average cost to acquire shares. The agreements require the Company to make up-front payments to the counterparty financial institutions which results in either the receipt of stock at the beginning of the term of the agreements followed by a share adjustment at the maturity of the agreements, or the receipt of either stock or cash at the maturity of the agreements, depending upon the price of the stock.
	During 2014, the Company repurchased 996,967 shares (2013 – 5,019,606; 2012 – 4,001,850 shares) at an average price of $38.59 (2013 – $36.55; 2012 – $39.16) for a total cost of $38 million (2013 – $183 million; 2012 – $157 million).
	Since the inception of the Program, the Company repurchased 23,337,980 shares at an average price of $39.21 for a total cost of $915 million. All shares repurchased are recorded as Treasury stock on the Consolidated Balance Sheets under the par value method at $0.01 per share.
	The authorized stated capital consists of the following:
	PREFERRED SHARES
	The Company is authorized to issue 20 million preferred shares, par value $0.01 per share. The Board of Directors of the Company will determine the voting powers (if any) of the shares, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares at the time of issuance. No preferred shares were outstanding at December 31, 2014 or December 31, 2013.
	COMMON STOCK
	The Company is authorized to issue two billion shares of common stock, par value $0.01 per share. Holders of the Company’s common stock are entitled to one vote per share.
	The changes in the number of outstanding common stock and their aggregate stated value during the years ended December 31, 2014 and December 31, 2013, were as follows:
			December 31,					December 31,

	-1	The Company issued 10,635,436 shares out of Treasury stock in order to complete the transaction. During 2014, the Company repurchased 996,967 shares (2013 – 5,019,606) and issued 87,541 shares (2013 – 156,136) out of Treasury stock in conjunction with the exercise of stock-based compensation awards.
	Domtar (Canada) Paper Inc. Exchangeable Shares
	Upon the consummation of a series of transactions whereby the Fine Paper Business of Weyerhaeuser Company was transferred to the Company and it acquired Domtar Inc. on March 7, 2007 (Domtar Inc. shareholders had the option to receive either common stock of the Company or shares of Domtar (Canada) Paper Inc., a subsidiary of Domtar Corporation, that were exchangeable for common stock of the Company. The exchangeable shares of Domtar (Canada) Paper Inc. were intended to be substantially the economic equivalent to shares of the Company’s common stock. These shareholders could exchange the exchangeable shares for shares of Domtar Corporation common stock on a one-for-one basis at any time.
	On June 2, 2014 (the “Redemption Date”), Domtar (Canada) Paper Inc. redeemed all of its outstanding exchangeable shares from the holders thereof. On the Redemption Date, holders of exchangeable shares received, in exchange for each exchangeable share, one share of common stock of Domtar Corporation (plus cash in the amount of all declared and unpaid dividends, if any, provided that the record date for the payment of such dividends was prior to the Redemption Date).
	As a result of the redemption of exchangeable shares, the Company reclassified $32 million from Exchangeable shares to Additional paid-in capital.

Commitments and Contingencies	NOTE 22.
	COMMITMENTS AND CONTINGENCIES
	ENVIRONMENT
	The Company is subject to environmental laws and regulations enacted by federal, provincial, state and local authorities.
	In 2014, the Company’s operating expenses for environmental matters, as described in Note 1, amounted to $68 million (2013 – $69 million; 2012 – $64 million).
	The Company made capital expenditures for environmental matters of $14 million in 2014 (2013 – $4 million; 2012 – $4 million). No amounts were spent under the Pulp and Paper Green Transformation Program in 2014 as all projects were completed in 2013, and reimbursed by the Government of Canada (2013 – nil; 2012 – $6 million), for the improvement of air emissions and energy efficiency, effluent treatment and remedial actions to address environmental compliance.
	An action was commenced by Seaspan International Ltd. (“Seaspan”) in the Supreme Court of British Columbia, on March 31, 1999 against the Company and others with respect to alleged contamination of Seaspan’s site bordering Burrard Inlet in North Vancouver, British Columbia, including contamination of sediments in Burrard Inlet, due to the presence of creosote and heavy metals. Beyond the filing of preliminary pleadings, no steps have been taken by the parties in this action. On February 16, 2010, the government of British Columbia issued a Remediation Order to Seaspan and the Company (“responsible persons”) in order to define and implement an action plan to address soil, sediment and groundwater issues. This Order was appealed to the Environmental Appeal Board (“Board”) on March 17, 2010 but there is no suspension in the execution of this Order unless the Board orders otherwise. The relevant government authorities selected a remediation approach on July 15, 2011, and on January 8, 2013, the same authorities decided that each responsible persons’ implementation plan is satisfactory and that the responsible persons should decide which plan is to be used. Most of the remaining appeals that were to be heard before the Board were abandoned by the parties during the course of the Board proceedings which were held in the fall of 2013. Seaspan and Domtar have selected a remedial plan and have applied to the Vancouver Fraser Port Authority for permitting approval. The Company has recorded an environmental reserve to address its estimated exposure. The possible loss in excess of the reserve is not considered to be material for this matter.
	The following table reflects changes in the reserve for environmental remediation and asset retirement obligations:
		December 31,			December 31,
		2014			2013

		$			$			$		$		$		$		$
	Environmental provision and other asset retirement obligations		16			14			1		1		2		70		104
	The Company is also a party to various proceedings relating to the cleanup of hazardous waste sites under the Comprehensive Environmental Response Compensation and Liability Act, commonly known as “Superfund,” and similar state laws. The U.S. Environmental Protection Agency (“EPA”) and/or various state agencies have notified the Company that it may be a potentially responsible party with respect to other hazardous waste sites as to which no proceedings have been instituted against the Company. The Company continues to take remedial action under its Care and Control Program at its former wood preserving sites, and at a number of operating sites due to possible soil, sediment or groundwater contamination. The investigation and remediation process is lengthy and subject to the uncertainties of changes in legal requirements, technological developments and, if and when applicable, the allocation of liability among potentially responsible parties.
	Climate change regulation
	In response to the Kyoto Protocol, which calls for reductions of certain emissions that may contribute to increases in atmospheric greenhouse gas (“GHG”) concentrations, various international, national and local laws have been proposed or implemented focusing on reducing GHG emissions. These actual or proposed laws do or may apply in the jurisdictions where the Company currently has, or may have in the future, manufacturing facilities or investments.
	In the United States, Congress has considered legislation to reduce emissions of GHGs. Although the legislation has not passed, the U.S. government is promulgating resolutions under the existing Clean Air Act to reduce GHG emissions from public utilities and certain other emitters. The EPA has adopted and implemented GHG permitting requirements for certain new sources and modifications of existing industrial facilities and has proposed GHG performance standards for newly constructed, reconstructed and modified electric utilities. The EPA has also relied on the existing Clean Air Act to propose a “Clean Power Plan” that will set emission guidelines for existing electric utilities and require states to develop plans for reducing GHG emissions by making significant changes to the energy resources utilized within the state. The EPA has developed a biogenic carbon accounting framework to account for carbon dioxide emissions from biomass fuels for Clean Air Act permitting purposes. The EPA references this framework in the proposals addressing GHG performance standards for the electric utilities. Furthermore, several states are already regulating GHG emissions from public utilities and certain other significant emitters, primarily through regional GHG cap-and-trade programs or renewable energy requirements.
	The U.S. Supreme Court held on June 23, 2014 that the EPA had exceeded its statutory authority in establishing its GHG permitting program. Specifically, the Court determined that the EPA could not impose GHG permitting requirements on a source unless that source had already triggered permitting requirements for other non-GHG pollutants. However, for sources already subject to permitting, the Court held that the Clean Air Act did not preclude the EPA from requiring those sources to install “best available control technology” for GHGs.
	Passage of GHG legislation by Congress or individual states, or the adoption of regulations by the EPA or analogous state agencies, that restrict emissions of GHGs in areas in which the Company conducts business could have a variety of impacts upon the Company, including requiring it to implement GHG reduction programs or to pay taxes or other fees with respect to its GHG emissions. This, in turn, could increase the Company’s operating costs and capital spending. The Company does not expect to be disproportionately affected by these measures compared with other pulp and paper producers in the United States.
	The Government of Canada has committed to reducing Canada’s greenhouse gases by 17 percent from 2005 levels by 2020. A sector-by-sector approach is being used to set performance standards to reduce greenhouse gases. The Government of Canada has implemented regulations intended to regulate emissions from motor vehicles and has enacted regulations to reduce GHG emissions from coal-fired electrical generators which are scheduled to become effective July 1, 2015. Proposed regulations relating to GHG emissions from the oil and gas sector are currently in consultation and are expected to come into force in 2016. Performance standards for industrial sectors will also be developed. The pulp and paper sector is currently undergoing review. The Company does not expect the performance standards to be disproportionately affected by these future measures compared with other pulp and paper producers in Canada.
	The province of Quebec initiated a GHG cap-and-trade system on January 1, 2012. Reduction targets for Quebec became effective January 1, 2013. The Company does not expect the cost of compliance will have a material impact on the Company’s financial position, results of operations or cash flows. British Columbia imposed a carbon tax in 2008, which applies to the purchase of fossil fuels within the province. There are currently no other federal or provincial statutory or regulatory obligations that affect the emission of GHGs for the Company’s pulp and paper operations elsewhere in Canada. The Province of Ontario is expected to initiate development of a regulatory program for GHG emission reductions in early 2015.
	While it is likely that there will be increased regulation relating to GHG emissions in the future, at this time it is not possible to estimate either a timetable for the promulgation or implementation of any new regulations or the Company’s cost of compliance to said regulations. The impact could, however, be material.
	Industrial Boiler Maximum Achievable Control Technology Standard (“MACT”)
	The EPA published in the Federal Register on January 31, 2013, for major sources, a new set of standards related to emissions from boilers and process heaters included in some of the Company’s manufacturing processes. These standards are generally referred to as Boiler MACT and seek to require reductions in the emission of certain hazardous air pollutants or surrogates of hazardous air pollutants. The EPA announced the final rule on December 20, 2012 and it was subsequently published in the Federal Register on January 31, 2013 for major sources. The Company is developing plans to bring facilities affected by the Boiler MACT rule into compliance by the January 2016 regulatory deadline for major sources. The Company expects that the capital cost required to comply with the Boiler MACT rules is between $18 million and $25 million. Of this amount, in 2014, the Company has spent $10 million for costs related to Boiler MACT compliance. The Company is currently assessing the associated increase in operating costs as well as alternate compliance strategies.
	The EPA has agreed to reconsider a limited number of issues in the most recent Boiler MACT rule, and elements of the EPA’s rule have been legally challenged. Since the consequences of these activities cannot be predicted, adjustments to compliance plans may be needed to accommodate any changes to the final rule.
	CONTINGENCIES
	In the normal course of operations, the Company becomes involved in various legal actions mostly related to contract disputes, patent infringements, environmental and product warranty claims, and labor issues. While the final outcome with respect to actions outstanding or pending at December 31, 2014, cannot be predicted with certainty, it is management’s opinion that, except as noted below, their resolution will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.
	Spanish Competition Investigation
	In September 2014, following preliminary inquiries commenced in January 2014, Spain’s National Commission of Markets and Competition initiated a formal investigation of several companies and their parent companies, including Indas (a subsidiary of the Company, acquired on January 2, 2014), and two of its affiliates, as well as an industry association, Federacion Espanola de Empresas de Tecnologia Sanitaria (“FENIN”), with respect to possible unlawful conduct, consisting of fixing prices, commercial terms and dispensation of heavy adult incontinence products in the Spanish market. The activities under investigation predate the acquisition of Indas by the Company. The sellers of Indas made representations and warranties to the Company in the purchase agreement regarding, among other things, Indas’ and its subsidiary’s compliance with competition laws. The liability retained by the sellers is backed by bank guarantees, and limited insurance coverage has been purchased with regards to excess liability. As a result, while the final outcome with respect to the investigation cannot be predicted with certainty, it is management’s opinion that its resolution will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.
	LEASE AND OTHER COMMERCIAL COMMITMENTS
	The Company has entered into operating leases for property, plant and equipment. The Company also has commitments to purchase property, plant and equipment, roundwood, wood chips, gas and certain chemicals. Purchase orders in the normal course of business are excluded from the table below. Any amounts for which the Company is liable under purchase orders are reflected in the Consolidated Balance Sheets as Trade and other payables. Minimum future payments under these operating leases and other commercial commitments, determined at December 31, 2014, were as follows:
		2015			2016			2017		2018		2019		Thereafter		Total
		$			$			$		$		$		$		$
	Operating leases		25			19			14		13		10		53		134
	Other commercial commitments		89			5			4		1		—		—		99
	Total operating lease expense amounted to $32 million in 2014 ($32 million in 2013 and $34 million in 2012).
	INDEMNIFICATIONS
	In the normal course of business, the Company offers indemnifications relating to the sale of its businesses and real estate. In general, these indemnifications may relate to claims from past business operations, the failure to abide by covenants and the breach of representations and warranties included in the sales agreements. Typically, such representations and warranties relate to taxation, environmental, product and employee matters. The terms of these indemnification agreements are generally for an unlimited period of time. At December 31, 2014, the Company is unable to estimate the potential maximum liabilities for these types of indemnification guarantees as the amounts are contingent upon the outcome of future events, the nature and likelihood of which cannot be reasonably estimated at this time. Accordingly, no provision has been recorded. These indemnifications have not yielded a significant expense in the past.
	Pension Plans
	The Company has indemnified and held harmless the trustees of its pension funds, and the respective officers, directors, employees and agents of such trustees, from any and all costs and expenses arising out of the performance of their obligations under the relevant trust agreements, including in respect of their reliance on authorized instructions from the Company or for failing to act in the absence of authorized instructions. These indemnifications survive the termination of such agreements. At December 31, 2014 the Company has not recorded a liability associated with these indemnifications, as it does not expect to make any payments pertaining to these indemnifications.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities and Fair Value Measurement	NOTE 23.
	DERIVATIVES AND HEDGING ACTIVITIES AND FAIR VALUE MEASUREMENT
	HEDGING PROGRAMS
	The Company is exposed to market risk, such as changes in currency exchange rates, commodity prices, and interest rates. To the extent we decide to manage the volatility related to these exposures, the Company may enter into various financial derivatives that are accounted for under the derivatives and hedging guidance. These transactions are governed by the Company’s hedging policies which provide direction on acceptable hedging activities, including instrument type and acceptable counterparty exposure.
	Upon inception, the Company formally documents the relationship between hedging instruments and hedged items. At inception and quarterly thereafter, the Company formally assesses whether the financial instruments used in hedging transactions are effective at offsetting changes in either the cash flow or the fair value of the underlying exposures. The ineffective portion of the qualifying instrument is immediately recognized to earnings. The amount of ineffectiveness recognized was immaterial for all years presented. The Company does not hold derivative financial instruments for trading purposes.
	CREDIT RISK
	The Company is exposed to credit risk on the accounts receivable from its customers. In order to reduce this risk, the Company reviews new customers’ credit history before granting credit and conducts regular reviews of existing customers’ credit performance. As of December 31, 2014, one of Domtar’s Pulp and Paper segment customers located in the United States represented 10% ($64 million) (2013 – 12% ($73 million)) of the Company’s receivables.
	The Company is exposed to credit risk in the event of non-performance by counterparties to its financial instruments. The Company minimizes this exposure by entering into contracts with counterparties that are believed to be of high credit quality. Collateral or other security to support financial instruments subject to credit risk is usually not obtained. The credit standing of counterparties is regularly monitored.
	INTEREST RATE RISK
	The Company is exposed to interest rate risk arising from fluctuations in interest rates on its cash and cash equivalents, bank indebtedness, bank credit facility and long-term debt. The Company’s objective in managing exposure to interest rate changes is to minimize the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. The Company may manage this interest rate exposure through the use of derivative instruments such as interest rate swap contracts, whereby it agrees to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount. On December 18, 2014, the Company entered into a $100 million notional 2.5 year fixed to floating interest rate swap to receive fixed (1.0225%) and pay the 3 month LIBOR. This swap was designated as a fair value hedge for a portion of our 10.75% notes due June 2017. The changes in fair value of both the hedging and the hedged item are immediately recognized in interest expense. No amount has been recorded in 2014 related to the interest rate swap entered into in December 2014.
	COST RISK
	Cash flow hedges:
	The Company purchases natural gas at the prevailing market price at the time of delivery. To reduce the impact on cash flow and earnings due to pricing volatility, the Company may utilize derivatives to fix the price of forecasted natural gas purchases. The changes in the fair value on qualifying instruments are included in Accumulated other comprehensive loss to the extent effective, and reclassified into Cost of sales in the period during which the hedged transaction affects earnings. Current contracts are used to hedge a portion of forecasted purchases over the next three years.
	The following table presents the volumes under derivative financial instruments for natural gas contracts outstanding as of December 31, 2014 to hedge forecasted purchases:
	Commodity		Notional contractual					Notional contractual value			Percentage of forecasted
			quantity under derivative					under derivative contracts			purchases under

	2016			7,995,000		MMBTU	(1)	$	33			41	%
	2017			2,340,000		MMBTU	(1)	$	10			12	%
	-1	MMBTU: Millions of British thermal units
	The natural gas derivative contracts were fully effective as of December 31, 2014. There were no amounts reflected in the Consolidated Statements of Earnings and Comprehensive Income for the year ended December 31, 2014 resulting from hedge ineffectiveness (2013 and 2012 – nil).
	FOREIGN CURRENCY RISK
	Cash flow hedges:
	The Company has manufacturing operations in the United States, Canada and Europe. As a result, it is exposed to movements in foreign currency exchange rates in Canada and Europe. Moreover, certain assets and liabilities are denominated in currencies other than the U.S. dollar and are exposed to foreign currency movements. Accordingly, the Company’s earnings are affected by increases or decreases in the value of the Canadian dollar and the European currencies. The Company’s European subsidiaries are also exposed to movements in foreign currency exchange rates on transactions denominated in a currency other than their Euro functional currency. The Company’s risk management policy allows it to hedge a significant portion of its exposure to fluctuations in foreign currency exchange rates for periods up to three years. The Company may use derivative financial instruments (currency options and foreign exchange forward contracts) to mitigate its exposure to fluctuations in foreign currency exchange rates.
	Derivatives are used to hedge forecasted purchases in Canadian dollars by its Canadian subsidiary over the next 24 months. Derivatives are also used to hedge forecasted sales in British pounds and Norwegian krone and forecasted purchases in U.S. dollars and Swedish krona by its European subsidiaries over the next 12 months. Such derivatives are designated as cash flow hedges. The changes in the fair value on qualifying instruments are included in Accumulated other comprehensive loss to the extent effective, and reclassified into Sales or Cost of sales in the period during which the hedged transaction affects earnings.

	The foreign exchange derivative contracts were fully effective as of December 31, 2014. There were no amounts reflected in the Consolidated Statements of Earnings and Comprehensive Income for the year ended December 31, 2014 resulting from hedge ineffectiveness (2013 and 2012 - nil).
	FAIR VALUE MEASUREMENT
	The accounting standards for fair value measurements and disclosures, establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three levels. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is available and significant to the fair value measurement.
		Level 1	Quoted prices in active markets for identical assets or liabilities.
		Level 2	Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		Level 3	Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.
	The following tables present information about the Company’s financial assets and financial liabilities measured at fair value on a recurring basis (except Long-term debt, see (c) below) at December 31, 2014 and December 31, 2013, in accordance with the accounting standards for fair value measurements and disclosures and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value.

(a)	Fair value of the Company’s derivatives is classified under Level 2 (inputs that are observable; directly or indirectly) as it is measured as follows:
	•		For currency derivatives: Fair value is measured using techniques derived from the Black-Scholes pricing model. Interest rates, forward market rates and volatility are used as inputs for such valuation techniques.
	•		For natural gas contracts: Fair value is measured using the discounted difference between contractual rates and quoted market future rates.
(b)	ABN are reported at fair value utilizing Level 2 or Level 3 inputs. Fair value of ABN reported under Level 2 is based on current market quotes. Fair value of ABN reported under Level 3 is based on the value of the collateral investments held in the conduit issuer, reduced by the negative value of credit default derivatives, with an additional discount applied for illiquidity. These ABN are held outside of the Company’s pension plans.
(c)	Fair value of the Company’s long-term debt is measured by comparison to market prices of its debt. The debt transferred from Level 1 to Level 2 was due to lower trading activities. In accordance with US GAAP, the Company’s long-term debt is not carried at fair value on the Consolidated Balance Sheets at December 31, 2014 and December 31, 2013. However, fair value disclosure is required. The carrying value of the Company’s long-term debt is $1,350 million and $1,514 million at December 31, 2014 and December 31, 2013, respectively.
Due to their short-term maturity, the carrying amounts of cash and cash equivalents, receivables, bank indebtedness, trade and other payables and income and other taxes approximate their fair values.

	SEGMENT DISCLOSURES
	The Company operates in the two reportable segments described below. Each reportable segment offers different products and services and requires different manufacturing processes, technology and/or marketing strategies. The following summary briefly describes the operations included in each of the Company’s reportable segments:
		•		Pulp and Paper Segment–comprises the design, manufacturing, marketing and distribution of communication, specialty and packaging papers, as well as softwood, fluff and hardwood market pulp.
		•		Personal Care Segment–consists of the manufacturing, marketing and distribution of absorbent hygiene products.
	The accounting policies of the reportable segments are the same as described in Note 1. The Company evaluates performance based on operating income, which represents sales, reflecting transfer prices between segments at fair value, less allocable expenses before interest expense and income taxes. Segment assets are those directly used in segment operations.
	The Company attributes sales to customers in different geographical areas on the basis of the location of the customer.
	Long-lived assets consist of property, plant and equipment, intangible assets and goodwill used in the generation of sales in the different geographical areas.
	An analysis and reconciliation of the Company’s business segment information to the respective information in the financial statements is as follows:

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Principles	ACCOUNTING PRINCIPLES
	The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements include the accounts of Domtar Corporation and its controlled subsidiaries. Intercompany transactions have been eliminated on consolidation. Investment in an affiliated company, where the Company has joint control over their operations, is accounted for by the equity method.
Use of Estimates	USE OF ESTIMATES
	The consolidated financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the year, the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. On an ongoing basis, management reviews the estimates and assumptions, including but not limited to those related to closure and restructuring costs, income taxes, useful lives, asset impairment charges, goodwill and intangible asset impairment assessment, environmental matters and other asset retirement obligations, pension and other post-retirement benefit plans and, commitments and contingencies, based on currently available information. Actual results could differ from those estimates.
Foreign Currency Matters	TRANSLATION OF FOREIGN CURRENCIES
	The Company determines its international subsidiaries’ functional currency by reviewing the currencies in which their respective operating activities occur. The Company translates assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using the rate in effect at the balance sheet date and revenues and expenses are translated at the average exchange rates during the year. Foreign currency translation gains and losses are included in Shareholders’ equity as a component of Accumulated other comprehensive loss in the accompanying Consolidated Balance Sheets.
	Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is recognized in the Consolidated Statements of Earnings and Comprehensive Income and is partially offset by our hedging program (refer to Note 23 “Derivatives and hedging activities and fair value measurement”).
	At December 31, 2014, the accumulated translation adjustment accounts amounted to $(48) million (2013 – $152 million).
Revenue Recognition	REVENUE RECOGNITION
	Domtar Corporation recognizes revenue when pervasive evidence of an arrangement exists, the customer takes title and assumes the risks and rewards of ownership, the sales price charged is fixed or determinable and when collection is reasonably assured. Revenue is recorded at the time of shipment for terms designated free on board (“f.o.b.”) shipping point. For sales transactions designated f.o.b. destination, revenue is recorded when the product is delivered to the customer’s delivery site, when the title and risk of loss are transferred.
Shipping and Handling Costs	SHIPPING AND HANDLING COSTS
	The Company classifies shipping and handling costs as a component of Cost of sales in the Consolidated Statements of Earnings and Comprehensive Income.
Closure and Restructuring Costs	CLOSURE AND RESTRUCTURING COSTS
	Closure and restructuring costs are recognized as liabilities in the period when they are incurred and are measured at their fair value. For such recognition to occur, management, with the appropriate level of authority, must have approved and committed to a firm plan and appropriate communication to those affected must have occurred. These provisions may require an estimation of costs such as severance and termination benefits, pension and related curtailments, environmental remediation and may also include expenses related to demolition and outplacement. Actions taken may also require an evaluation of any remaining assets to determine required write-downs, if any, and a review of estimated remaining useful lives which may lead to accelerated depreciation expense.
	Estimates of cash flows and fair value relating to closures and restructurings require judgment. Closure and restructuring liabilities are based on management’s best estimates of future events at December 31, 2014. Closure and restructuring cost estimates are dependent on future events. Although the Company does not anticipate significant changes, the actual costs may differ from these estimates due to subsequent developments such as the results of environmental studies, the ability to find a buyer for assets set to be dismantled and demolished and other business developments. As such, additional costs and further working capital adjustments may be required in future periods.
Income Taxes	INCOME TAXES
	Domtar Corporation uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined according to differences between the carrying amounts and tax bases of the assets and liabilities. The Company records its worldwide tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. The change in the net deferred tax asset or liability is included in Income tax (benefit) expense or in Other comprehensive (loss) income in the Consolidated Statements of Earnings and Comprehensive Income. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to apply in the years in which the assets and liabilities are expected to be recovered or settled. Uncertain tax positions are recorded based upon the Company’s evaluation of whether it is “more likely than not” (a probability level of more than 50 percent) that, based upon its technical merits, the tax position will be sustained upon examination by the taxing authorities. The Company establishes a valuation allowance for deferred tax assets when it is more likely than not that they will not be realized. In general, “realization” refers to the incremental benefit achieved through the reduction in future taxes payable or an increase in future taxes refundable from the deferred tax assets.
	The Company recognizes interest and penalties related to income tax matters as a component of Income tax (benefit) expense in the Consolidated Statements of Earnings and Comprehensive Income.
Cash and Cash Equivalents	CASH AND CASH EQUIVALENTS
	Cash and cash equivalents include cash and short-term investments with original maturities of less than three months and are presented at cost which approximates fair value.
Receivables	RECEIVABLES
	Receivables are recorded net of a provision for doubtful accounts that is based on expected collectability. The securitization of receivables is accounted for as secured borrowings. Accordingly, financing expenses related to the securitization of receivables are recognized in earnings as a component of Interest expense in the Consolidated Statements of Earnings and Comprehensive Income.
Inventories	INVENTORIES
	Inventories are stated at the lower of cost or market. Cost includes labor, materials and production overhead. The last-in, first-out (“LIFO”) method is used to cost certain U.S. raw materials, in process and finished goods inventories. LIFO inventories were $229 million and $215 million at December 31, 2014 and 2013, respectively. The balance of U.S. raw material inventories, all materials and supplies inventories and all foreign inventories are costed at either the first-in, first-out (“FIFO”) or average cost methods. Had the inventories for which the LIFO method is used been valued under the FIFO method, the amounts at which product inventories are stated would have been $66 million and $72 million greater at December 31, 2014 and 2013, respectively.
Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment are stated at cost less accumulated depreciation including asset impairment write-downs. Interest costs are capitalized for significant capital projects. For timberlands, the amortization is calculated using the unit of production method. For all other assets, amortization is calculated using the straight-line method over the estimated useful lives of the assets. Buildings and improvements are amortized over periods of 10 to 40 years and machinery and equipment over periods of 3 to 20 years. No depreciation is recorded on assets under construction.
Impairment of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETS
	Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances indicating that the carrying value of the assets may not be recoverable, as measured by comparing the net book value of the asset group to their estimated undiscounted future cash flows. Impaired assets are recorded at estimated fair value, determined principally by using discounted future cash flows expected from their use and eventual disposition (refer to Note 4 “Impairment and write-down of property, plant and equipment and intangible assets”).
Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill is not amortized and is evaluated at the beginning of the fourth quarter of every year, or more frequently, whenever indicators of potential impairment exist. The Company performs the impairment test of goodwill at its reporting unit’s level.
	The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount including goodwill. In performing the qualitative assessment, the Company identifies the relevant drivers of fair value of a reporting unit and the relevant events and circumstances that may have an impact on those drivers of fair value. This process involves significant judgement and assumptions including the assessment of the results of the most recent fair value calculations, the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, specific events affecting the Company and the business, and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill, then it performs Step I of the two-step impairment test. The Company can also elect to bypass the qualitative assessment and proceed directly to the Step I of the impairment test.
	The first step is to compare the fair value of a reporting unit to its carrying amount, including goodwill. Significant judgement is required to estimate the fair value of a reporting unit.
	The Company typically uses an income method to determine the fair value of a reporting unit. Under the income approach, the Company estimates the fair value of a reporting unit based on the present value of estimated future cash flows. The assumptions used in the model requires estimating future sales volumes, selling prices and costs, changes in working capital, investments in property, plant and equipment and the selection of the appropriate discount rate. Sensitivities of these fair value estimates to change in assumptions are also performed. Assumptions used in our impairment evaluations are consistent with internal projections and operating plans. Unanticipated market and macroeconomic events and circumstances may occur and could affect the exactitude and validity of management assumptions and estimates.
	In the event that the net carrying amount exceeds the fair value of the business, the second step of the impairment test must be performed in order to determine the amount of the impairment charge. Fair value of goodwill in Step II of the impairment test is estimated in the same way as goodwill was determined at the date of the acquisition in a business combination, that is, the excess of the fair value of the reporting unit over the fair value of the identifiable net assets of the business.
	All goodwill as of December 31, 2014 resides in the Personal Care reporting segment, and originates from the acquisitions of Attends Healthcare Inc. on September 1, 2011, Attends Healthcare Limited on March 1, 2012, EAM Corporation on May 10, 2012, AHP on July 1, 2013 and Laboratorios Indas on January 2, 2014. Please refer to Note 3 “Acquisition of businesses” for additional information regarding the most recent acquisition.
	Indefinite-lived intangible assets are not amortized and are evaluated at the beginning of the fourth quarter of every year, or more frequently whenever indicators of potential impairment exist. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of indefinite-lived intangible assets are less than their carrying amounts. The qualitative assessment follows the same process as the one performed for goodwill, as described above. If, after assessing the qualitative factors, the Company determines that it is more likely than not that the indefinite-lived intangible assets are less than their carrying amounts, then a quantitative impairment test is required. The Company can also elect to proceed directly to the quantitative test. The quantitative impairment test consists of comparing the fair value of the indefinite-lived intangible assets determined using a variety of methodologies to their carrying amount. If the carrying amounts of the indefinite-lived intangible assets exceed their fair value, an impairment loss is recognized in an amount equal to that excess. Indefinite-lived intangible assets include trade names related to Attends®, IncoPack®, Indasec®, catalog rights related to Laboratorios Indas S.A.U., and license rights related to Xerox. The Company reviews its indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support indefinite useful lives.
	Definite lived intangible assets are stated at cost less amortization and are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Definite lived intangible assets include water rights, customer relationships, technology, non-compete agreements as well as licensing rights, which are being amortized using the straight-line method over their respective estimated useful lives. Any potential impairment for definite lived intangible assets will be calculated in the same manner as that disclosed under impairment of long-lived assets.
	Amortization is based mainly on the following useful lives:
			Useful life
	Water rights			40 years
	Customer relationships			10 to 40 years
	Technology			7 to 20 years
	Non-Compete agreements			9 years
	Licence rights			12 years
Other Assets	OTHER ASSETS
	Other assets are recorded at cost. Direct financing costs related to the issuance of long-term debt are deferred and amortized using the effective interest rate method.
Environmental Costs and Asset Retirement Obligations	ENVIRONMENTAL COSTS AND ASSET RETIREMENT OBLIGATIONS
	Environmental expenditures for effluent treatment, air emission, landfill operation and closure, asbestos containment and removal, bark pile management, silvicultural activities and site remediation (together referred to as environmental matters) are expensed or capitalized depending on their future economic benefit. In the normal course of business, Domtar Corporation incurs certain operating costs for environmental matters that are expensed as incurred. Expenditures for property, plant and equipment that prevent future environmental impacts are capitalized and amortized on a straight-line basis over 10 to 40 years. Provisions for environmental matters are not discounted, due to uncertainty with respect to timing of expenditures, and are recorded when remediation efforts are probable and can be reasonably estimated.
	Asset retirement obligations are recognized, at fair value, in the period in which Domtar Corporation incurs a legal obligation associated with the retirement of an asset. Conditional asset retirement obligations are recognized, at fair value, when the fair value of the liability can be reasonably estimated or on a probability-weighted discounted cash flow estimate. The associated costs are capitalized as part of the carrying value of the related asset and depreciated over its remaining useful life. The liability is accreted using the credit adjusted risk-free interest rate used to discount the cash flow.
Stock-Based Compensation and Other Stock-Based Payments	STOCK-BASED COMPENSATION AND OTHER STOCK-BASED PAYMENTS
	Domtar Corporation recognizes the cost of employee services received in exchange for awards of equity instruments over the requisite service period, based on their grant date fair value for awards accounted for as equity and based on the quoted market value of each reporting period for awards accounted for as liability. The Company awards are accounted for as compensation expense and presented in Additional paid-in-capital on the Consolidated Balance Sheets for equity type awards and presented in Other liabilities and deferred credits on the Consolidated Balance Sheets for liability type awards.
	The Company’s awards may be subject to market, performance and/or service conditions. Any consideration paid by plan participants on the exercise of stock options or the purchase of shares is credited to Additional paid-in-capital on the Consolidated Balance Sheets. The par value included in the Additional paid-in-capital component of stock-based compensation is transferred to Common shares upon the issuance of shares of common stock.
	Unless otherwise determined at the time of the grant, awards subject to service conditions vest in approximately equal installments over three years beginning on the first anniversary of the grant date and performance-based awards vest based on achievement of pre-determined performance goals over performance periods of three years. The majority of non-qualified stock options and performance share units expire at various dates no later than seven years from the date of grant. Deferred Share Units vest immediately at the grant date and are remeasured at each reporting period, until settlement, using the quoted market value.
	Under the 2007 Omnibus Incentive Plan (“Omnibus Plan”), a maximum of 2,394,415 shares are reserved for issuance in connection with awards granted or to be granted.
Derivative Instruments	DERIVATIVE INSTRUMENTS
	Derivative instruments are utilized by Domtar Corporation as part of the overall strategy to manage exposure to fluctuations in foreign currency, interest rate and commodity price on certain purchases. As a matter of policy, derivatives are not used for trading or speculative purposes. All derivatives are recorded at fair value either as assets or liabilities. When derivative instruments have been designated within a hedge relationship and are highly effective in offsetting the identified risk characteristics of specific financial assets and liabilities or group of financial assets and liabilities, hedge accounting is applied. In a fair value hedge, changes in fair value of derivatives are recognized in the Consolidated Statements of Earnings and Comprehensive Income. The change in fair value of the hedged item attributable to the hedged risk is also recorded in the Consolidated Statements of Earnings and Comprehensive Income by way of a corresponding adjustment of the carrying amount of the hedged item recognized in the Consolidated Balance Sheets. In a cash flow hedge, changes in fair value of derivative instruments are recorded in Other comprehensive (loss) income. These amounts are reclassified in the Consolidated Statements of Earnings and Comprehensive Income in the periods in which results are affected by the cash flows of the hedged item within the same line item. Any hedge ineffectiveness is recorded in the Consolidated Statements of Earnings and Comprehensive Income when incurred.
Pension Plans	PENSION PLANS
	Domtar Corporation’s plans include funded and unfunded defined benefit and defined contribution pension plans. Domtar Corporation recognizes the overfunded or underfunded status of defined benefit and underfunded defined contribution pension plans as an asset or liability in the Consolidated Balance Sheets. The net periodic benefit cost includes the following:
		•		The cost of pension benefits provided in exchange for employees’ services rendered during the period,
		•		The interest cost of pension obligations,
		•		The expected long-term return on pension fund assets based on a market value of pension fund assets,
		•		Gains or losses on settlements and curtailments,
		•		The straight-line amortization of past service costs and plan amendments over the average remaining service period of approximately 8 years of the active employee group covered by the plans, and
		•		The amortization of cumulative net actuarial gains and losses in excess of 10% of the greater of the accrued benefit obligation or market value of plan assets at the beginning of the year over the average remaining service period of approximately 8 years of the active employee group covered by the plans.
	The defined benefit plan obligations are determined in accordance with the projected unit credit actuarial cost method.
Other Post-Retirement Benefit Plans	OTHER POST-RETIREMENT BENEFIT PLANS
	The Company recognizes the unfunded status of other post-retirement benefit plans (other than multiemployer plans) as a liability in the Consolidated Balance Sheets. These benefits, which are funded by Domtar Corporation as they become due, include life insurance programs, medical and dental benefits and short-term and long-term disability programs. The Company amortizes the cumulative net actuarial gains and losses in excess of 10% of the accrued benefit obligation at the beginning of the year over the average remaining service period of approximately 10 years of the active employee group covered by the plans.
Business Combination	BUSINESS COMBINATION
	The Company applies the acquisition method of accounting in a business combination. In general, this methodology requires companies to record assets acquired and liabilities assumed at their respective fair market values at the date of acquisition. The value is determined from the viewpoint of market participants. Any amount of the purchase price paid that is in excess of the estimated fair values of net assets acquired is recorded in the line item goodwill in the consolidated balance sheets. Management’s judgment is used to determine the estimated fair values assigned to assets acquired and liabilities assumed, as well as asset useful lives for property, plant and equipment and amortization periods for intangible assets, and can materially affect the Company’s results of operations. Transaction costs, as well as costs to reorganize acquired companies, are expensed as incurred in the Company’s consolidated statement of income.
Guarantees	GUARANTEES
	A guarantee is a contract or an indemnification agreement that contingently requires Domtar Corporation to make payments to the other party of the contract or agreement, based on changes in an underlying item that is related to an asset, a liability or an equity security of the other party or on a third party’s failure to perform under an obligating agreement. It could also be an indirect guarantee of the indebtedness of another party, even though the payment to the other party may not be based on changes in an underlying item that is related to an asset, a liability or an equity security of the other party. Guarantees, when applicable, are accounted for at fair value.
Future Accounting Changes [Member]
Foreign Currency Matters	FOREIGN CURRENCY MATTERS
	In March 2013, the FASB issued ASU 2013-05, an update to Foreign Currency Matters, which indicates that a cumulative translation adjustment is attached to the parent’s investment in a foreign entity and should be released in a manner consistent with the derecognition guidance on investments in entities. Thus, the entire amount of the cumulative translation adjustment associated with the foreign entity would be released when there has been (1) a sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity; (2) a loss of a controlling financial interest in an investment in a foreign entity; or (3) a step acquisition for a foreign entity. The update does not change the requirement to release a pro rata portion of the cumulative translation adjustment of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity.
	The Company adopted the new requirement on January 1, 2014 with no impact on the Company’s consolidated financial statements, as no triggering event occurred throughout the period.
Revenue Recognition	REVENUE FROM CONTRACTS WITH CUSTOMERS
	In May 2014, the FASB issued ASU 2014-09, an update on revenue from contracts with customers. The core principal of this guideline is that an entity should recognize revenue, to depict the transfer of promised goods or services to customers, in an amount that reflects the consideration for which the entity is entitled to, in exchange for those goods and services. Guidance in this section supersedes the revenue recognition requirements found in topic 605.
	The amendment will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently evaluating these changes to determine whether they have an impact on the presentation of the consolidated financial statements.
Income Taxes	INCOME TAXES
	In July 2013, the FASB issued ASU 2013-11, which provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This accounting standard update requires entities to assess whether or not to net the unrecognized tax benefit with a deferred tax asset as of the reporting date.
	The Company adopted the new requirement on January 1, 2014 with no material impact on the Company’s consolidated financial statements except for the change in presentation.
Stock-Based Compensation and Other Stock-Based Payments	STOCK COMPENSATION
	In June 2014, the FASB issued ASU 2014-12, an update on stock compensation. The guideline requires performance targets, which affect vesting and can be achieved after the requisite service period, to be treated as a performance condition. Accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If achievement of the performance target becomes probable before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period.
	The amendments are effective for interim and annual periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect these changes to have a material impact on the consolidated financial statements.
Push Down Accounting	PUSH DOWN ACCOUNTING
	In November 2014, the FASB issued ASU 2014-17, an update to business combinations and push down accounting. The amendments in this update provide an acquired entity with an option to apply pushdown in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply push down accounting in the reporting period in which the change in control event occurs.
	The Company adopted the new requirement on the effective date with no impact on the Company’s consolidated financial statements.
Discontinued Operations	DISCONTINUED OPERATIONS
	In April 2014, the FASB issued ASU 2014-08, an update on Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The amendments in this update change the requirements for reporting discontinued operations and require additional disclosures for both disposal transactions that meet the criteria for a discontinued operation and disposals that do not meet these criteria. The objective of this update is to reach a greater convergence between the FASB’s and IASB’s reporting requirements for discontinued operations.
	The amendments are effective for interim and annual periods beginning after December 15, 2014 and will not have an impact on the Company’s consolidated financial statements unless a disposal transaction occurs after the effective date. Early adoption is permitted.
Going Concern	GOING CONCERN
	In August 2014, the FASB issued ASU 2014-15, an update on going concern financial statements disclosure. The amendment requires the entity’s management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued.
	The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. This amendment is not expected to have an impact on the Company’s consolidated financial statements.

	(b)	The settlement loss of $19 million in the pension plans for the year ended December 31, 2014 is related to the previously closed Ottawa, Ontario paper mill. The settlement loss of $13 million in the pension plans for the year ended December 31, 2013 is related to the previously closed Big River and Dryden mills for $6 million and $7 million, respectively (see Note 16 “Closure and restructuring costs and liability”). The settlement loss for the year ended December 31, 2012 of $1 million is related to the sale of hydro assets in Ottawa, Ontario and Gatineau, Quebec.
	(c)	The curtailment gain of $12 million for the year ended December 31, 2012 is a result of the curtailment of benefits related to the majority of employees covered by the plan.
Key Assumptions to Measure Accrued Benefit Obligation and Net Periodic Benefit Cost	The Company used the following key assumptions to measure the accrued benefit obligation and the net periodic benefit cost. These assumptions are long-term, which is consistent with the nature of employee future benefits.
	Pension plans		December 31,			December 31,			December 31,
			2014			2013			2012
	Accrued benefit obligation
	Discount rate			3.9	%		4.1	%		4.1	%
	Rate of compensation increase			2.7	%		2.7	%		2.7	%
	Net periodic benefit cost
	Discount rate			4.7	%		4.2	%		4.8	%
	Rate of compensation increase			2.7	%		2.8	%		2.8	%
	Expected long-term rate of return on plan assets			6.4	%		5.8	%		6	%
	Discount rate for Canadian plans: 3.9% based on a model whereby cash flows are projected for hypothetical plans and are discounted using a spot rate yield curve developed from bond yield data for AA corporate bonds. Specifically, short-term yields to maturity are derived from actual AA rated corporate bond yield data. For longer terms, extrapolated data is used. The extrapolated data are created by adding a term-based spread over long provincial bond yields. The spread is based on the observed spreads between AA rated corporate bonds and AA rated provincial bonds in three sections of the yield curve.
	Discount rate for U.S. plans: 3.85% obtained by incorporating the Company’s qualified plans’ expected cash flows in the Mercer Yield Curve which is based on bonds rated AA or better by Moody’s or Standard & Poor’s, excluding callable bonds, bonds of less than a minimum issue size, and certain other bonds. Effective December 2012, the universe of bonds also includes private placement (traded in reliance on Rule 144A and with at least two years to maturity), make whole, and foreign corporation (denominated in US dollars) bonds.
	Effective January 1, 2015, the Company will use 5.6% (2014 – 6.4%; 2013 – 5.8%) as the expected return on plan assets, which reflects the current view of long-term investment returns. The overall expected long-term rate of return on plan assets is based on management’s best estimate of the long-term returns of the major asset classes (cash and cash equivalents, equities, and bonds) weighted by the actual allocation of assets at the measurement date, net of expenses. This rate includes an equity risk premium over government bond returns for equity investments and a value-added premium for the contribution to returns from active management. The sources used to determine management’s best estimate of long-term returns are numerous and include country specific bond yields, which may be derived from the market using local bond indices or by analysis of the local bond market, and country-specific inflation and investment market expectations derived from market data and analysts’ or governments’ expectations as applicable.
	Other post-retirement benefit plans		December 31,			December 31,			December 31,
			2014			2013			2012
	Accrued benefit obligation
	Discount rate			3.9	%		4.8	%		4.2	%
	Rate of compensation increase			2.8	%		2.8	%		2.8	%
	Net periodic benefit cost
	Discount rate			4.8	%		4.2	%		2.9	%
	Rate of compensation increase			2.7	%		2.8	%		2.8	%
Effect of One Percent Change in Assumed Health Care Cost	For measurement purposes, a 5.2% weighted average annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014. The rate was assumed to decrease gradually to 4.1% by 2033 and remain at that level thereafter. An increase or decrease of 1% of this rate would have the following impact:
			Increase of 1%		Decrease of 1%
			$		$
	Impact on net periodic benefit cost for other post-retirement benefit plans		1		-1
	Impact on accrued benefit obligation		9		-8

	(a)	Fair value of the Company’s derivatives is classified under Level 2 (inputs that are observable; directly or indirectly) as it is measured as follows:
		•		For currency derivatives: Fair value is measured using techniques derived from the Black-Scholes pricing model. Interest rates, forward market rates and volatility are used as inputs for such valuation techniques.
		•		For natural gas contracts: Fair value is measured using the discounted difference between contractual rates and quoted market future rates.
	(b)	ABN are reported at fair value utilizing Level 2 or Level 3 inputs. Fair value of ABN reported under Level 2 is based on current market quotes. Fair value of ABN reported under Level 3 is based on the value of the collateral investments held in the conduit issuer, reduced by the negative value of credit default derivatives, with an additional discount applied for illiquidity. These ABN are held outside of the Company’s pension plans.
	(c)	Fair value of the Company’s long-term debt is measured by comparison to market prices of its debt. The debt transferred from Level 1 to Level 2 was due to lower trading activities. In accordance with US GAAP, the Company’s long-term debt is not carried at fair value on the Consolidated Balance Sheets at December 31, 2014 and December 31, 2013. However, fair value disclosure is required. The carrying value of the Company’s long-term debt is $1,350 million and $1,514 million at December 31, 2014 and December 31, 2013, respectively.
