Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities and Fair Value Measurement	NOTE 4. ________________ 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, interest rates and prices of the Company’s common stock with regard to the Company’s stock-based compensation program. To the extent the Company decides 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 Company does not hold derivative financial instruments for trading purposes. CREDIT RISK The Company is exposed to credit risk on 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 September 30, 2020, two Pulp and Paper segment customers located in the U.S. represented 11% or $62 million, and 10% or $55 million, respectively, of the Company’s receivables (December 31, 2019 – two Pulp and Paper segment customers located in the U.S. represented 11% or $66 million, and 11% or $65 million, respectively). The Company is exposed to credit risk in the event of non-performance by counterparties to its financial instruments. The Company attempts to minimize 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, revolving credit facility and securitization, term loan 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 its 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. EQUITY RISK The Company is exposed to changes in share prices with regard to its stock-based compensation program. The Company manages its exposure through the use of derivative instruments such as equity swap contracts. In March 2020, the Company entered into a total return swap agreement covering 500,000 common shares maturing on March 4, 2022. COST RISK Cash flow hedges: The Company is exposed to price volatility for raw materials and energy used in its manufacturing process. The Company manages its exposure to cost risk primarily through the use of supplier contracts. 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 39 months. The following table presents the volumes under derivative financial instruments for natural gas contracts outstanding as of September 30, 2020 to hedge forecasted purchases: Commodity Notional contractual quantity under derivative contracts MMBtu (2) Notional contractual value under derivative contracts (in millions of dollars) Percentage of forecasted purchases under derivative contracts Natural gas 2020 (1) 2,384,843 $ 7 35% 2021 9,270,000 $ 27 39% 2022 9,270,000 $ 25 37% 2023 4,210,000 $ 12 16% (1) Represents the remaining three months of 2020 (2) MMBtu: Millions of British thermal units The natural gas derivative contracts were effective as of September 30, 2020. 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 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 the Company’s Canadian subsidiary over the next 24 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 following table presents the currency values under significant currency positions pursuant to currency derivatives outstanding as of September 30, 2020 to hedge forecasted purchases and sales: Currency exposure hedged Business Segment Year of maturity Notional contractual value Percentage of forecasted net exposures under contracts Average Protection rate Average Obligation rate CAD/USD Pulp and Paper 2020 (1) 226 CAD 95% 1 USD = 1.3259 1 USD = 1.3426 CAD/USD Pulp and Paper 2021 721 CAD 76% 1 USD = 1.3412 1 USD = 1.3558 CAD/USD Pulp and Paper 2022 304 CAD 32% 1 USD = 1.3606 1 USD = 1.3606 (1) The foreign exchange derivative contracts were effective as of September 30, 2020. FAIR VALUE MEASUREMENT The accounting standards for fair value measurements and disclosures establish 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 (b) below) at September 30, 2020 and December 31, 2019, 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.

Income Taxes	NOTE 8. _________________ INCOME TAXES For the third quarter of 2020, the Company’s income tax benefit was $55 million, consisting of a current income tax benefit of $7 million and a deferred income tax benefit of $48 million. This compares to an income tax benefit of $1 million in the third quarter of 2019, consisting of a current income tax benefit of $3 million and a deferred income tax expense of $2 million. The Company received income tax refunds, net of payments of $1 million during the third quarter of 2020. The effective tax rate was 38% compared with an effective tax rate of -5% in the third quarter of 2019. The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate and then making adjustments for discrete items arising in that quarter. In each interim quarter the Company updates its estimate of the annual effective tax rate and, if the estimated annual tax rate changes, makes a cumulative adjustment in that quarter. The effective tax rate for the third quarter of 2020 was significantly impacted by such an adjustment, mainly due to a change in the mix of earnings or loss between tax jurisdictions. The effective tax rate for the third quarter of 2020 was also favorably impacted by the CARES Act, which granted companies the ability to carry back tax losses generated in the U.S. in 2020 to a tax year with earnings that were taxed at a higher statutory tax rate. The effective tax rate for the third quarter of 2019 was favorably impacted by additional R&D tax credits in the U.S. and Spain and by the finalization of certain estimates in connection with the filing of the Company’s 2018 income tax returns. For the first nine months of 2020, the Company’s income tax benefit was $67 million, consisting of a current income tax benefit of $7 million and a deferred income tax benefit of $60 million. This compares to an income tax expense of $28 million in the first nine months of 2019, consisting of a current income tax expense of $27 million and a deferred income tax expense of $1 million. The Company received refunds, net of income tax payments, of $25 million during the first nine months of 2020. The effective tax rate was 50% compared to an effective tax rate of 19% in the first nine months of 2019. The effective tax rate for the first nine months of 2020 was significantly impacted by the mix of earnings or loss in the Company’s major jurisdictions, by the recognition of additional tax credits in various jurisdictions, and by the ability to carry back U.S. tax losses generated in 2020 to a tax year with earnings that were taxed at a higher statutory tax rate. These favorable impacts were partially offset by an increase in the valuation allowance related to the expected realization of certain U.S. state tax credits. The effective tax rate for the first nine months of 2019 was favorably impacted by the recognition of additional R&D credits in the U.S. and Spain and by an enacted law change in the state of Arkansas, which were mostly offset by the recording of a valuation allowance against certain state tax credit carryforwards and by the finalization of certain estimates in connection with the filing of the Company’s 2018 income tax returns.

Restructuring And Related Activities [Abstract]
Closure and Restructuring Costs and Impairment of Long-lived Assets	NOTE 12. _________________ CLOSURE AND RESTRUCTURING COSTS AND IMPAIRMENT OF LONG-LIVED ASSETS Cost reduction program The Company is implementing a cost savings program. As part of this program, on August 7, 2020, the Company announced the permanent closure of the uncoated freesheet manufacturing at the Kingsport, Tennessee and Port Huron, Michigan mills, the remaining paper machine at the Ashdown, Arkansas mill and the converting center in Ridgefields, Tennessee. These actions will reduce the Company’s annual uncoated freesheet paper capacity by approximately 721,000 short tons, and will result in a workforce reduction of approximately 750 employees. The Kingsport and Ashdown paper machines, which have been idled since April 2020, did not recommence operations. The Ridgefields converting center ceased operations at the end of the third quarter of 2020, while the Port Huron mill is expected to shut down by the end of the first quarter of 2021. The Company plans to enter the linerboard market with the conversion of the Kingsport paper machine. Domtar estimates the conversion cost to be between $300 and $350 million. As a result of the decision to change the nature and use of the Kingsport, Tennessee mill, the carrying amount of the remaining assets of the Kingsport mill has been tested for impairment and resulted in no additional impairment charge in the quarter. The carrying amount of these assets was approximately $80 million at September 30, 2020. The Company is also completing the conversion of the Ashdown mill to 100% softwood and fluff pulp, which is requiring $15 to $20 million of capital investments and is expected to be completed within nine to twelve months. During the third quarter of 2020, the Company recorded $111 million of accelerated depreciation under Impairment of long-lived assets on the Consolidated Statement of Earnings (Loss) and Comprehensive Income (Loss). Additionally, the Company recorded $29 million of severance and termination costs, $31 million of inventory obsolescence, $2 million of pension curtailment loss and $6 million of other costs, under Closure and restructuring costs on the Consolidated Statement of Earnings (Loss) and Comprehensive Income (Loss). Ashdown, Arkansas mill and Port Huron, Michigan mill On September 27, 2019, the Company’s Board of Directors approved the decision to permanently shut down two paper machines, which was announced on October 3, 2019. The closures took place at the Ashdown, Arkansas pulp and paper mill and the Port Huron, Michigan paper mill. As a result, the Company recorded, in the third quarter of 2019, $32 million of accelerated depreciation under Impairment of long-lived assets on the Consolidated Statement of Earnings (Loss) and Comprehensive Income (Loss). Additionally, the Company recorded $1 million of severance and termination costs and $4 million of inventory obsolescence, under Closure and restructuring costs. Waco, Texas facility On November 1, 2018, the Company announced a margin improvement plan within the Personal Care Division. As part of this plan, the Board of Directors approved the permanent closure of its Waco, Texas Personal Care manufacturing and distribution facility, the relocation of certain of its manufacturing assets and a workforce reduction across the division. The Waco, Texas facility ceased operations during the second quarter of 2019. For the three and nine months ended September 30, 2019, the Company recorded $1 million of accelerated depreciation and $26 million of accelerated depreciation and impairment of operating lease right-of-use assets, respectively, under Impairment of long-lived assets on the Consolidated Statement of Earnings (Loss) and Comprehensive Income (Loss). For the three and nine months ended September 30, 2019, the Company also recorded $1 million and $5 million, respectively, of severance and termination costs; $1 million and $2 million, respectively, of inventory obsolescence; and $4 million and $11 million, respectively, of asset relocation and other costs, under Closure and restructuring costs. Other costs For the three and nine months ended September 30, 2020, other costs related to previous and ongoing closures and restructuring included nil and $1 million, respectively, of severance and termination costs (2019 – nil).

Equity [Abstract]
Shareholders' Equity	NOTE 15. _________________ SHAREHOLDERS’ EQUITY DIVIDENDS On February 18, 2020, the Company’s Board of Directors approved a quarterly dividend of $0.455 per share, to be paid to holders of the Company’s common stock. Total dividends of approximately $25 million were paid on April 15, 2020 to shareholders of record on April 2, 2020. STOCK REPURCHASE PROGRAM The Company’s Board of Directors has authorized a stock repurchase program (the “Program”) of up to $1.3 billion. On November 5, 2019, the Company’s Board of Directors approved an increase to the Program from $1.3 billion to $1.6 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. 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 in part to reduce the dilutive effects of stock options and awards, and to improve shareholders’ returns. The Company makes open market purchases of its common stock using general corporate funds. Additionally, the Company may enter 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 would require the Company to make up-front payments to the counterparty financial institutions, which would result 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 the first nine months of 2020, the Company repurchased 1,798,306 shares at an average price of $33.05 for a total cost of $59 million. During the first nine months of 2019, the Company repurchased 4,076,723 shares at an average price of $35.47 for a total cost of $145 million. SUSPENSION OF CAPITAL RETURN PROGRAM On May 5, 2020, due to the unprecedented market conditions and uncertainty caused by COVID-19, the Company suspended the payment of its regular quarterly dividend and stock repurchase program in order to preserve cash and provide additional flexibility in the current environment. The Board of Directors will continue to evaluate the Company’s capital return program based upon customary considerations, including market conditions.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 16. _________________ COMMITMENTS AND CONTINGENCIES ENVIRONMENTAL MATTERS The Company is subject to environmental laws and regulations enacted by federal, provincial, state and local authorities. The Company may also incur substantial costs in relation to enforcement actions (including orders requiring corrective measures, installation of pollution control equipment or other remedial actions) as a result of violations of, or liabilities under, environmental laws and regulations applicable to its past and present properties. The Company’s ongoing efforts to identify potential environmental concerns that may be associated with such properties may result in additional environmental costs and liabilities which cannot be reasonably estimated at this time. A former owner of the Company’s Dryden, Ontario manufacturing site (the "Dryden Property") operated a chlor-alkali plant during the 1960s and 1970s, during which time mercury and other pollutants were used and discharged into the natural environment. In conjunction with the sale and redevelopment of the Dryden Property, the Province of Ontario (the “Province”) provided a broad indemnity (the "Indemnity") in 1985 to the then purchaser of the Dryden Property and its successors and assigns with respect to the discharge of any pollutant, including mercury, by the historical operators of the Dryden Property. This Indemnity subsequently was assigned to the Company in connection with its 2007 purchase of the Dryden Property. As the current owner of the Dryden Property, the Company is actively engaged with the Province with respect to the management of the historical contamination. The Province issued a Director's order under environmental laws to certain prior owners of the Dryden Property in connection with a nearby waste disposal site that has never been owned by the Company. The Director's order required certain work to be conducted by those prior owners. The prior owners asserted that the Indemnity covered the work required by the Director’s order. Following extensive litigation, the Supreme Court of Canada found, among other things, that the Indemnity covered third-party claims, but not first-party claims, such as the Director's order. In the future, the Province may challenge whether the Company has the benefit of the Indemnity. In addition to the Indemnity, the Company has other recourses relating to the historical contamination. The situation involving the historical contamination is continuing to develop, and the Company cannot predict its outcome. While the Company currently does not believe that it will be required to incur costs that would have a material impact on its results of operations or financial condition, there is no certainty that this is in fact the case. The following table reflects changes in the reserve for environmental remediation and asset retirement obligations: September 30, 2020 $ Balance at beginning of year 35 Additions and other changes 4 Environmental spending (2 ) Effect of foreign currency exchange rate change (1 ) Balance at end of period 36 The U.S. Environmental Protection Agency (the “EPA”) and/or various state agencies have notified the Company that it may be a potentially responsible party under the Comprehensive Environmental Response Compensation and Liability Act, commonly known as “Superfund”, and similar state laws 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. 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 September 30, 2020, cannot be predicted with certainty, it is management’s opinion that their resolution will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. 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 September 30, 2020, 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. As of September 30, 2020, the Company has not recorded a liability associated with these indemnifications, as it does not expect to make any payments pertaining to these indemnifications. GENERAL RISK FACTORS Climate change and air quality regulation Various national and local laws and regulations relating to climate change have been established or are emerging in jurisdictions where the Company currently has, or may have in the future, manufacturing facilities or investments. The EPA repealed the Clean Power Plan and replaced it with the “Affordable Clean Energy” (“ACE”) rule. Unlike the Clean Power Plan, which would have required significant changes across the entire power sector, ACE only requires states to develop plans for efficiency improvements at coal-fired electric utility generating units. The rule has been challenged in the U.S. Court of Appeals for the D.C. Circuit. Regardless of the outcome for the ACE rule, the Company does not expect to be disproportionately affected compared with other pulp and paper producers located in the states where the Company operates. The province of Quebec has a greenhouse gases (“GHG”) cap-and-trade system with reduction targets. British Columbia has a carbon tax that applies to the purchase of fossil fuels within the province. The Company does not expect its facilities to be disproportionately affected by these measures compared to the other pulp and paper producers located in these provinces. The Government of Canada has established a federal carbon pricing system in provinces that do not already impose a cost on carbon emissions. The Government of Canada has imposed its carbon pricing program for regulating GHG emissions in Ontario, which took effect on January 1, 2019. To reduce GHG emissions and recognize the unique circumstances of the province’s diverse economy, Ontario finalized its own GHG Emission Performance Standards regulation. The Ontario Government has been in discussions with the Canadian Government to replace the federal program in Ontario with its provincial program. The Ontario Government has announced the federal government will accept its program as an alternative to the federal program. Timing for this transition and any additional environmental costs that may result from this effort cannot be reasonably estimated at this time. The EPA proposed to revise its Industrial Boiler Maximum Achievable Control Technology Standard (“MACT”) , or Boiler MACT , in a notice published on August 24, 2020. The proposed rule is a response to two court decisions that remanded certain issues for further review by the EPA, and it includes revisions to 34 different emission limitations that could apply to some of the Company’s facilities. Although the EPA has indicated that a small number of facilities may need to reduce emissions further compared to the current limits, t he Company does not expect its facilities to be disproportionately aff ected compared to other U.S. pulp and paper producers .

Segment Reporting [Abstract]
Segment Disclosures	NOTE 17. _________________ SEGMENT DISCLOSURES The Company’s two reportable segments described below also represent its two operating segments. 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 – consists of the design, manufacturing, marketing and distribution of communication, specialty and packaging papers, as well as softwood, fluff and hardwood market pulp. • Personal Care – consists of the design, manufacturing, marketing and distribution of absorbent hygiene products. As a result of changes in Domtar’s organization structure, the Company has changed its segment reporting. Starting January 1, 2020, Domtar’s materials business, EAM Corporation, a manufacturer of high quality airlaid and ultrathin laminated cores, previously reported under its Personal Care segment is now presented under its Pulp and Paper segment. Prior period segment results have been restated to the new segment presentation with no significant impact on segment results. There were no changes to the Company’s consolidated sales or operating income.
