Corporate Information And Statement Of IFRS Compliance [Abstract]
The Company	The Company Organization Canada Goose Holdings Inc. and its subsidiaries (the “Company”) design, manufacture, and sell premium outdoor apparel for men, women, youth, children, and babies. The Company’s apparel collections include various styles of parkas, jackets, shells, vests, knitwear, footwear, and accessories for fall, winter, and spring seasons. The Company’s head office is located at 250 Bowie Avenue, Toronto, Canada M6E 4Y2. The use of the terms “Canada Goose”, “we”, “us” and “our” throughout these notes to the consolidated financial statements refer to the Company. Canada Goose is a public company listed on the Toronto Stock Exchange and the New York Stock Exchange under the trading symbol “GOOS”. The principal shareholders of the Company are investment funds advised by Bain Capital LP and its affiliates (“Bain Capital”), and DTR LLC, DTR (CG) Limited Partnership, and DTR (CG) II Limited Partnership (collectively “DTR”), entities indirectly controlled by the President and Chief Executive Officer of the Company. The principal shareholders hold multiple voting shares representing 46.3% of the total shares outstanding as at March 31, 2019 , or 89.6% of the combined voting power of the total voting shares outstanding. Subordinate voting shares that trade on public markets represent 53.7% of the total shares outstanding as at March 31, 2019 , or 10.4% of the combined voting power of the total voting shares outstanding. Statement of compliance The accompanying consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). These consolidated financial statements were authorized for issuance by the Company’s Board of Directors on May 28, 2019. Fiscal year The fiscal year-end of the Company ends on March 31 . Basis of presentation These consolidated financial statements have been prepared on the historical cost basis except for the following items, which are recorded at fair value: • financial instruments, including derivative financial instruments, at fair value in other comprehensive income and through profit or loss, and • initial recognition of assets acquired and liabilities assumed in a business combination. The significant accounting policies set out below have been applied consistently in the preparation of the consolidated financial statements for all periods presented, with the exception of transitional provisions applied in adopting new accounting standards (note 4). These consolidated financial statements are presented in Canadian dollars, the Company’s functional and presentation currency. Basis of consolidation Subsidiaries are entities controlled by the Company. Control exists when the Company has power over, exposure or rights to variable returns from the Company’s involvement with the entity, and the ability to use its power over the entity to affect the amount of the Company’s returns. The financial accounts and results of subsidiaries are included in the consolidated financial statements of the Company from the date that control commences until the date that control ceases.

Corporate Information And Statement Of IFRS Compliance [Abstract]
Significant accounting policies	Significant accounting policies (a) Operating segments An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Company’s other components, and for which discrete financial information is available. Segment operating results are reviewed regularly to make decisions about resources to be allocated to the segment and assess its performance. The Company classifies its business in two operating and reportable segments: Wholesale and Direct-to-Consumer. The Wholesale business comprises sales made to a mix of functional and fashionable retailers, including major luxury department stores, outdoor specialty stores, individual shops, and to international distributors. The Direct-to-Consumer business comprises sales through our country-specific e-commerce platforms and Company-owned retail stores located in luxury shopping malls and high street locations. (b) Foreign currency translation Functional and presentation currency Items included in the consolidated financial statements of the Company’s subsidiaries are measured in the functional currency, which is using the currency of the primary economic environment in which each entity operates. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation when items are remeasured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the changes at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the statement of income in selling, general and administrative expenses, except when included in other comprehensive income for qualifying cash flow and net investment hedges. Foreign operations The Company’s foreign operations are principally conducted through Canada Goose US, Inc., Canada Goose International AG,and CG (Shanghai) Trading Co. Ltd. The assets and liabilities of subsidiaries whose functional currency is not the Canadian dollar are translated into the functional currency of the Company using the exchange rate at the reporting date. Revenues and expenses are translated at exchange rates prevailing at the transaction date. The resulting foreign exchange translation differences are recorded as a currency translation adjustment in other comprehensive income. (c) Seasonality We experience seasonal fluctuations in our revenue and operating results and historically have realized a significant portion of our wholesale revenue and operating income for the year during our second and third fiscal quarters and Direct-to-Consumer revenue and operating income in our third and fourth fiscal quarters. Thus, lower-than-expected net revenue in these periods could have an adverse impact on our annual operating results. Working capital requirements typically increase during the first and second quarters of the fiscal year as inventory builds to support peak shipping and selling periods and, accordingly, typically decrease during the third and fourth quarter of the fiscal year as inventory is sold and trade receivables are converted to cash. After retail stores are opened, operating costs in our Direct-to-Consumer channel are consistent over the year while revenue and related cash collections fluctuate. Borrowings on our revolving facility have historically increased over the first and second quarters and are repaid in the third quarter of the fiscal year. Cash flows from operating activities are typically highest in the third and fourth quarters of the fiscal year due to the timing of collection of wholesale trade receivables and revenue in the Direct-to-Consumer channel during that period and increased cash inflows from the peak selling season. (d) Revenue recognition Revenue comprises of the consideration to which the Company expects to be entitled in exchange for the sale of goods in the ordinary course of the Company’s activities. Revenue is presented net of sales tax, estimated returns, sales allowances, and discounts. The Company recognizes revenue when the Company has agreed terms with its customers, the contractual rights and payment terms have been identified, the contract has commercial substance, it is probable that consideration will be collected by the Company, and when specific criteria for transfer of control to the customer have been met for each of the Company’s activities, as described below. i) Wholesale Wholesale revenue comprises sales of the Company's products to third-party resellers (which includes international distributors and retailers). Wholesale revenue from the sale of goods is recognized, net of an estimated provision for sales returns, discounts and allowances, when the control of the goods has been transferred to the reseller, which depends on the precise terms of the agreement with each reseller. The Company, at its discretion, may cancel all or a portion of any firm wholesale sales order. The Company is therefore obligated to return any prepayments or deposits made by resellers for which the product is not provided. All advance payments are therefore included in accrued liabilities in the statement of financial position. ii) Direct-to-Consumer Direct-to-Consumer revenue consists of sales through the Company’s e-commerce operations and Company-owned retail stores. Sales through e-commerce operations are recognized upon estimated delivery of the goods to the customer, net of an estimated provision for sales returns, when control of the goods has transferred from the Company to the customer. Sales through our Company-owned retail stores are recognized upon delivery to the customer at the point of sale, net of an estimated provision for sales returns. It is the Company’s policy to sell merchandise through the Direct-to-Consumer channel with a limited right to return, typically within 30 days. Accumulated experience is used to estimate and provide for such returns. The Company’s warranty obligation is to provide an exchange or repair for manufacturing defective products under the standard warranty terms and conditions. The warranty obligation is recognized as a provision when goods are sold. (e) Business combinations Acquisitions of businesses are accounted for using the acquisition method as of the acquisition date, which is the date when control is transferred to the Company. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition date fair values of the assets transferred, liabilities incurred by the Company and the equity interests issued by the Company in exchange for control of the acquiree. Transaction costs that the Company incurs in connection with a business combination are recognized in the statement of income as incurred. Goodwill is measured as the excess of the sum of the fair value of consideration transferred over the net of the acquisition date amounts of the identifiable assets acquired and the liabilities assumed. When the consideration transferred in a business combination includes contingent consideration, the contingent consideration is measured at its acquisition date fair value. Contingent consideration is remeasured at subsequent reporting dates at its fair value, and the resulting gain or loss recognized in the statement of income. (f) Earnings per share Basic earnings per share is calculated by dividing net income for the year attributable to ordinary equity holders of the common shares by the weighted average number of multiple and subordinated voting shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to ordinary equity holders of the Company by the weighted average number of multiple and subordinated voting shares outstanding during the year plus the weighted average number of subordinate shares that would be issued on the exercise of all stock options and settlement of restricted share units (“RSU”). (g) Income taxes Current and deferred income taxes are recognized in the consolidated statements of income and other comprehensive income, except when it relates to a business combination, or items recognized in equity or in other comprehensive income. Current income tax Current income tax is the expected income tax payable or receivable on the taxable income or loss for the period, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to income tax payable in respect of previous years. Deferred income tax Deferred income tax is provided using the liability method for temporary differences at the reporting date between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Deferred income tax is measured using enacted or substantively enacted income tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. A deferred tax asset is recognized for unused income tax losses and credits to the extent that it is probable that future taxable income will be available against which they can be utilized. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable income will allow the deferred tax asset to be recovered. Deferred income tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in other comprehensive income or directly in equity. Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred tax relates to the same taxable entity and the same taxation authority. Deferred income tax is provided on temporary differences arising on investments in subsidiaries, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future. (h) Cash Cash consists of cash and cash equivalents, including cash on hand, deposits in banks, and short-term deposits with maturities of less than 3 months. The Company uses the indirect method of reporting cash flow from operating activities. (i) Trade receivables Trade receivables, including credit card receivables, consist of amounts owing where we have extended credit to customers on product sales and are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, less expected credit loss and sales allowances. The allowance for expected credit loss is recorded against trade receivables and is based on historical experience. (j) Inventories Raw materials, work-in-process and finished goods are valued at the lower of cost and net realizable value. Cost is determined using the weighted average cost method. The cost of work-in-process and finished goods inventories include the cost of raw materials and an applicable share of the cost of labour and fixed and variable production overhead, including depreciation of property, plant and equipment used in the production of finished goods and design costs, and other costs incurred in bringing the inventories to their present location and condition. The Company estimates net realizable value as the amount at which inventories are expected to be sold, taking into consideration fluctuations in selling prices due to seasonality, less estimated costs necessary to complete the sale. Inventories are written down to net realizable value when the cost of inventories is estimated to be unrecoverable due to obsolescence, damage or declining selling prices. Inventory is adjusted to reflect estimated loss (“shrinkage”) incurred since the last inventory count. Shrinkage is based on historical experience. When circumstances that previously caused inventories to be written down below cost no longer exist or when there is clear evidence of an increase in realizable value, the amount of the write-down previously recorded is reversed. Storage costs, indirect administrative overhead and certain selling costs related to inventories are expensed in the period that these costs are incurred. (k) Property, plant and equipment Property, plant and equipment is stated at cost, net of accumulated depreciation and any accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of the asset, including costs incurred to prepare the asset for its intended use and capitalized borrowing costs, when the recognition criteria are met. The commencement date for capitalization of costs occurs when the Company first incurs expenditures for the qualifying assets and undertakes the required activities to prepare the assets for their intended use. Property, plant and equipment assets are depreciated on a straight-line basis over their estimated useful lives when the assets are available for use. When significant parts of a fixed asset have different useful lives, they are accounted for as separate components and depreciated separately. Depreciation methods and useful lives are reviewed annually and are adjusted for prospectively, if appropriate. Estimated useful lives are as follows: Asset Category Estimated Useful Life Plant equipment 10 years Computer hardware 5 years Leasehold improvements Lesser of the lease term or useful life of the asset Show displays 5 years Furniture and fixtures 3 to 15 years An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset, calculated as the difference between the net disposal proceeds and the carrying amount of the asset, is included in the statement of income when the asset is derecognized. The cost of repairs and maintenance of fixed assets is expensed as incurred and recognized in the statement of income. Property, plant and equipment are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, the entity will estimate the recoverable amount of the asset and record any impairment loss in the statement of income. (l) Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. The cost of an intangible asset acquired in a business combination is its fair value as at the date of acquisition. Following initial recognition, intangible assets with finite lives are carried at cost less any accumulated amortization and any accumulated impairment losses. Lease rights in connection with the opening of new Company-owned retail stores are recorded based on the amount paid. Lease rights have a definite useful life and are amortized on a straight-line basis over the term of the lease. An internally generated intangible asset is recorded for product development costs which are included within intellectual property. Product development costs are incurred in the design, production and testing of new products where the technical feasibility of commercial manufacturing and sale of the product has been demonstrated. The useful lives of intangible assets are assessed as either finite or indefinite. Asset Category Estimated Useful Life Brand name Indefinite Domain name Indefinite ERP software 7 years Computer software 5 years Lease rights Lease term Intellectual property 1 to 8 years Customer lists 4 years Intangible assets with indefinite useful lives comprise of the Canada Goose and Baffin brand names (note 5 ) and domain name, which were acquired as part of an acquisition and were recorded at their estimated fair value. The brand names and domain name are considered to have an indefinite life based on a history of revenue and cash flow performance, and the intent and ability of the Company to support the brand with spending to maintain its value for the foreseeable future. The brand names and domain name are tested at least annually for impairment, at the cash-generating unit (“CGU”) level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis. Intangible assets with finite lives are amortized over the useful economic life on straight-line basis. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of income over its estimated useful life. An intangible asset is derecognized on disposal or when no future economic benefits are expected from its use. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are included in the statement of income when the asset is derecognized. Intangible assets are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, the entity will estimate the recoverable amount of the asset and record any impairment loss in the statement of income. (m) Goodwill Goodwill represents the difference between the purchase price of an acquired business and the Company’s share of the net identifiable assets acquired and liabilities assumed and any contingent liabilities assumed. It is initially recorded at cost and subsequently measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to CGUs based on the lowest level within the entity in which the goodwill is monitored for internal management purposes. The allocation is made to those CGUs that are expected to benefit from the business combination in which the goodwill arose. Any potential impairment of goodwill is identified by comparing the recoverable amount of a CGU to its carrying value. Goodwill is reduced by the amount of deficiency, if any. If the deficiency exceeds the carrying amount of goodwill, the carrying values of the remaining assets in the CGU are reduced by the excess on a pro-rata basis. The Company tests goodwill for impairment annually in the fourth quarter of the fiscal year. The recoverable amount of a CGU is the higher of the estimated fair value less costs of disposal or value-in-use of the CGU. In assessing value-in-use, the estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. The Company has determined that the goodwill contributes to the cash flows of seven CGUs (2018 - six CGUs). (n) Provisions Provisions are recognized when the Company has a present obligation, legal or constructive, as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. Where the Company expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset but only when the reimbursement is virtually certain. The expense relating to any provision is presented in the statement of income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized in the statement of income. The provision for warranty returns relates to the Company’s obligation for defective goods sold to customers that have yet to be returned. Accruals for warranty returns are estimated on the basis of historical returns and are recorded so as to allocate them to the same period the corresponding revenue is recognized. (o) Employee future benefits The Company sponsors defined benefit pension plan membership, which is limited to certain employees of Canada Goose International AG and other subsidiaries who reside in Switzerland. The measurement date for the defined benefit pension plan is March 31 . The obligation associated with the Company’s defined benefit pension plan is actuarially valued using the projected unit credit method, management’s best estimate assumptions, salary escalation, inflation, life expectancy, and a current market discount rate. Assets are measured at fair value. The obligation in excess of plan assets is recorded as a liability. All actuarial gains or losses, net of tax, are recognized immediately through other comprehensive income. (p) Fair values Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability, or • In the absence of a principal market, in the most advantageous market for the asset or liability. The Company uses valuation techniques that it believes are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 : inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: are unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above. There was no change in the valuation techniques applied to financial instruments during all periods presented. The following table describes the valuation techniques used in the determination of the fair values of financial instruments: Type Valuation Approach Cash, trade receivables, accounts payable and accrued liabilities The carrying amount approximates fair value due to the short term maturity of these instruments. Derivatives (included in other current assets, other long-term assets, accounts payable and accrued liabilities or other long-term liabilities) Specific valuation techniques used to value derivative financial instruments include: - Quoted market prices or dealer quotes for similar instruments; - Observable market information as well as valuations determined by external valuators with experience in the financial markets. Revolving facility and term loan The fair value is based on the present value of contractual cash flows, discounted at the Company’s current incremental borrowing rate for similar types of borrowing arrangements or, where applicable, market rates. (q) Financial instruments Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the financial instrument. Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issuance of financial assets and financial liabilities (other than financial assets and financial liabilities classified at fair value through profit or loss) are added to, or deducted from, the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities classified at fair value through profit or loss are recognized immediately in profit or loss. Financial assets and financial liabilities are measured subsequently as described below. i) Non-derivative financial assets Non-derivative financial assets include cash and trade receivables which are measured at amortized cost. The Company initially recognizes receivables and deposits on the date that they are originated. The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. ii) Non-derivative financial liabilities Non-derivative financial liabilities include accounts payable, accrued liabilities, revolving facility, and term loan. The Company initially recognizes debt instruments issued on the date that they are originated. All other financial liabilities are recognized initially on the trade date at which the Company becomes a party to the contractual provisions of the instrument. Financial liabilities are recognized initially at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method. The Company derecognizes a financial liability when its contractual obligations are discharged or cancelled or expire. iii) Derivative financial instruments Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at each reporting date. The method of recognizing the resulting gain or loss depends on whether the derivative is designated and effective as a hedging instrument. When a derivative financial instrument, including an embedded derivative, is not designated and effective in a qualifying hedge relationship, all changes in its fair value are recognized immediately in the statement of income; attributable transaction costs are recognized in the statement of income as incurred. The Company does not use derivatives for trading or speculative purposes. Embedded derivatives are separated from a host contract and accounted for separately if the economic characteristics and risks of the host contract and the embedded derivative are not closely related. iv) Hedge accounting The Company is exposed to the risk of currency fluctuations and has entered into currency derivative contracts to hedge its exposure on the basis of planned transactions. Where hedge accounting is applied, the criteria are documented at the inception of the hedge and updated at each reporting date. The Company documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking the hedging transactions. The Company also documents its assessment, at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The fair value of a hedging derivative is classified as a current asset or liability when the maturity of the hedged item is less than twelve months, and as a non-current asset or liability when the maturity of the hedged item is more than twelve months. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized, net of tax, in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the statement of income. Amounts accumulated in other comprehensive income are transferred to the statement of income in the periods when the hedged item affects net income. When a forecast transaction that is hedged results in the recognition of a non-financial asset or liability, such as inventory, the amounts are included in the measurement of the cost of the related asset or liability. The deferred amounts are ultimately recognized in the statement of income. Hedges of net investments are accounted for similarly to cash flow hedges, with unrealized gains and losses recognized, net of tax, in other comprehensive income. Amounts included in other comprehensive income are transferred to the statement of income in the period when the foreign operation is disposed of or sold. (r) Share-based payments Share-based payments are valued based on the grant date fair value of these awards and the Company records compensation expense over the corresponding service period. The fair value of the share-based payments is determined using acceptable valuation techniques. The Company has issued stock options to purchase subordinate voting shares and RSUs under its equity incentive plans, prior to the public offering on March 21, 2017 (the “Legacy Plan”) and subsequently (the “Omnibus Plan”). Under the terms of the Legacy Plan, options were granted to certain employees of the Company with vesting contingent upon meeting the service, performance goals and exit event conditions of the Legacy Plan. There are two types of stock options: service-vested options are time based and generally vest over five years of service, and performance-based and exit event options vest upon attainment of performance conditions and the occurrence of an exit event. Under the terms of the Omnibus Plan, options are granted to certain executives of the Company with vesting, generally over four years , contingent upon meeting the service conditions of the Omnibus Plan. The compensation expense related to the options and RSUs is recognized ratably over the requisite service period, provided it is probable that the vesting conditions will be achieved and the occurrence of the exit event, if applicable, is probable. (s) Leases Operating lease payments net of any lease inducements are recognized as an expense in the statement of income on a straight-line basis over the lease term.

Corporate Information And Statement Of IFRS Compliance [Abstract]
Significant accounting judgments, estimates, and assumptions	Significant accounting judgments, estimates, and assumptions The preparation of the consolidated financial statements requires management to make estimates and judgments in applying the Company’s accounting policies that affect the reported amounts and disclosures made in the consolidated financial statements and accompanying notes. Estimates and assumptions are used mainly in determining the measurement of balances recognized or disclosed in the consolidated financial statements and are based on a set of underlying data that may include management’s historical experience, knowledge of current events and conditions and other factors that are believed to be reasonable under the circumstances. Management continually evaluates the estimates and judgments it uses. These estimates and judgments have been applied in a manner consistent with prior periods and there are no known trends, commitments, events or uncertainties that we believe will materially affect the methodology or assumptions utilized in making these estimates and judgments in these financial statements. The following are the accounting policies subject to judgments and key sources of estimation uncertainty that the Company believes could have the most significant impact on the amounts recognized in the consolidated financial statements. Inventories Key Sources of Estimation: Inventories are carried at the lower of cost and net realizable value. In estimating net realizable value, the Company uses estimates related to fluctuations in inventory levels, planned production, customer behaviour, obsolescence, future selling prices, seasonality and costs necessary to sell the inventory. Inventory is adjusted to reflect shrinkage incurred since the last inventory count. Shrinkage is based on historical experience. Impairment of non-financial assets (goodwill, intangible assets, and property, plant & equipment) Judgments Made in Relation to Accounting Policies Applied: Management is required to use judgment in determining the grouping of assets to identify their CGUs for the purposes of testing non-financial assets for impairment. Judgment is further required to determine appropriate groupings of CGUs for the level at which goodwill and intangible assets are tested for impairment. For the purpose of goodwill and intangible assets impairment testing, CGUs are grouped at the lowest level at which goodwill and intangible assets are monitored for internal management purposes. Judgment is also applied in allocating the carrying amount of assets to CGUs. In addition, judgment is used to determine whether a triggering event has occurred requiring an impairment test to be completed. The Company has concluded that it has seven CGUs and tests goodwill and these intangible assets for impairment on that basis. Key Sources of Estimation: In determining the recoverable amount of a CGU or a group of CGUs, various estimates are employed. The Company determines value in use by using estimates including projected future revenues, margins, costs, and capital investment consistent with strategic plans presented to the Board of Directors. Fair value less costs of disposal are estimated with reference to observable market transactions. Discount rates are consistent with external industry information reflecting the risk associated with Company and cash flows. Income and other taxes Key Sources of Estimation: In determining the recoverable amount of deferred tax assets, the Company forecasts future taxable income by legal entity and the period in which the income occurs to ensure that sufficient taxable income exists to utilize the attributes. Inputs to those projections are Board-approved financial forecasts and statutory tax rates. Judgments Made in Relation to Accounting Policies Applied: The calculation of current and deferred income taxes requires management to make certain judgments regarding the tax rules in jurisdictions where the Company performs activities. Application of judgments is required regarding the classification of transactions and in assessing probable outcomes of claimed deductions including expectations about future operating results, the timing and reversal of temporary differences and possible audits of income tax and other tax filings by the tax authorities. Functional currency Judgments Made in Relation to Accounting Policies Applied: The Company assesses the relevant factors related to the primary economic environment in which its entities operate to determine the functional currency. Where the assessment of primary indicators is mixed, management assesses the secondary indicators, including the relationship between the foreign operations and reporting entity. Financial instruments Key Sources of Estimation: The critical assumptions and estimates used in determining the fair value of financial instruments are: equity prices; future interest rates; the relative creditworthiness of the Company to its counterparties; estimated future cash flows; discount rates; and volatility utilized in option valuations. Trade receivables Key Sources of Estimation: The Company has a significant number of customers which minimizes the concentration of credit risk. The Company does not have any customers which account for more than 10% of sales or accounts receivable. We make ongoing estimates relating to the ability to collect our accounts receivable and maintain an allowance for estimated credit losses resulting from the inability of our customers to make required payments. In determining the amount of estimated credit losses, we consider our historical level of credit losses and make judgments about the creditworthiness of significant customers based on ongoing credit evaluations. Share-based payments Key Sources of Estimation: Compensation expense for share-based compensation granted is measured at the fair value at the grant date using the Black Scholes option pricing model for the year ended March 31, 2019 ; prior to the public offering, the Company used the Monte Carlo valuation model to measure the fair value of options granted. The critical assumptions used under both of these option valuation models at the grant date are: stock price valuation; exercise price; risk-free interest rate; expected time to exercise in years; expected dividend yield; and volatility. Warranty Key Sources of Estimation: The critical assumptions and estimates used in determining the warranty provision at the statement of financial position date are: number of jackets expected to require repair or replacement; proportion to be repaired versus replaced; period in which the warranty claim is expected to occur; cost of repair; cost of jacket replacement; and risk-free rate used to discount the provision to present value. Business combinations Key Sources of Estimation: In a business combination, the identifiable assets acquired and liabilities assumed will be recognized at their fair values. The Company makes judgments and estimates in determining the fair values. The excess of the purchase price over the fair values of identifiable assets acquired and liabilities assumed will be recognized as goodwill, if positive, and if negative, it is recognized in the statement of income.

Changes in accounting policies

Accounting Policies, Changes In Accounting Estimates And Errors [Abstract]
Changes in accounting policies	Changes in accounting policies Standards issued and adopted Certain new standards became effective at the beginning of the current fiscal year. The impact from the adoption of these new standards is described below. Revenue Effective for interim and annual financial statements relating to fiscal years beginning on or after January 1, 2018, the IASB issued IFRS 15, Revenue from Contracts with Customers (“IFRS 15”) which replaces the guidance on revenue recognition requirements that previously existed under IFRS. The new standard provides a comprehensive framework for the recognition, measurement and disclosure of revenue from contracts with customers, excluding contracts within the scope of the accounting standards on leases, insurance contracts and financial instruments. IFRS 15 also contains enhanced disclosure requirements. The Company adopted the standard effective April 1, 2018 using the modified retrospective approach, which resulted in no adjustment to opening retained earnings. Comparative information has not been restated and continues to be reported under previous accounting standards. After completing the analysis of its customer contracts, the Company has determined that the implementation of IFRS 15 did not result in any adjustments to the opening balance of retained earnings or to the presentation of the consolidated financial statements. As a result of adopting IFRS 15, the Company updated its accounting policies for the recognition of revenue (note 2 ). Financial instruments Effective for interim and annual financial statements relating to fiscal years beginning on or after January 1, 2018, the IASB issued IFRS 9, Financial Instruments (“IFRS 9”) which replaces IAS 39, Financial Instruments: Recognition and Measurement and all previous versions of IFRS 9. IFRS 9 introduces new requirements for classification and measurement, impairment, and hedge accounting and new impairment requirements that are based on a forward-looking expected credit loss model. IFRS 9 also amends other standards dealing with financial instruments such as IFRS 7, Financial Instruments: Disclosures . The Company adopted the standard effective April 1, 2018, resulting in no significant adjustment to retained earnings and no material effect on the consolidated financial statements. The Company assessed which business models apply to the financial assets and liabilities held and has classified its financial instruments into the appropriate IFRS 9 categories. Adoption of the new classification requirements under IFRS 9 did not result in significant changes in the measurement of financial assets and financial liabilities. The following table summarizes the original classification under IAS 39 and the new classification under IFRS 9 for the Company’s financial assets and financial liabilities: Asset/Liability Original classification under IAS 39 New classification under IFRS 9 Cash Loans and other receivables Amortized cost Trade receivables Loans and other receivables Amortized cost Accounts payable and accrued liabilities Other liabilities Amortized cost Revolving facility Other liabilities Amortized cost Term loan Other liabilities Amortized cost Derivatives, not in a hedging relationship Fair value through profit or loss Fair value through profit or loss Reclassification of financial assets is required if the objective of the business model in which they are held changes after initial recognition and if the change is significant to the entity’s operations. No reclassification of financial liabilities is permitted. Upon transition the Company’s derivatives designated as hedges continue to meet the hedging criteria, therefore the fair values flow through other comprehensive income under both IAS 39 and IFRS 9. Application of the expected credit loss model for trade accounts receivable did not result in any significant changes in the Company’s impairment allowance, with expected credit losses to be measured over the life of the asset, typically the annual wholesale sales cycle. The Company updated its accounting policies as a result of adopting IFRS 9 (note 2 ). Share-based payment Effective for interim and annual financial statements relating to fiscal years beginning on or after January 1, 2018, the IASB issued an amendment to IFRS 2, Share-based Payment , clarifying the accounting for certain types of share-based payment transactions. The Company adopted the standard effective April 1, 2018, with no material effect on the consolidated financial statements. Standards issued but not yet effective Certain new standards, amendments, and interpretations to existing IFRS standards have been published but are not yet effective and have not been adopted early by the Company. Management anticipates that pronouncements will be adopted in the Company’s accounting policy for the first period beginning after the effective date of the pronouncement. Information on new standards, amendments, and interpretations is provided below. Leases In January 2016, the IASB issued IFRS 16, Leases (“IFRS 16”), replacing IAS 17, Leases and related interpretations. The standard provides a new framework for lessee accounting that requires substantially all assets related to operating leases to be capitalized and a corresponding liability to be recorded. The new standard seeks to provide a more complete picture of a company’s leased assets and related liabilities and create greater comparability between companies who lease assets and those who purchase assets. IFRS 16 becomes effective for annual periods beginning on or after January 1, 2019 and is to be applied retrospectively. The standard permits the application of various transition options and practical expedients on initial adoption, and the more significant choices are described below. The Company will adopt the standard on April 1, 2019 using the modified retrospective approach with the cumulative effect of initial application recorded in opening retained earnings and no restatement of prior period financial information. Under the modified retrospective approach, the Company measured the right-of-use asset at the depreciated net book value as if the standard had been applied since the commencement date of the lease, but using the discount rate at the date of initial application. The Company used hindsight in determining the lease term at the date of initial application. The Company determined the discount rate at the time of initial adoption to be its incremental borrowing rate for each leased asset or portfolio of leased assets with similar characteristics by reference to the Company’s creditworthiness, the original term of the lease, the quality of the underlying leased asset, and the economic environment where the leased asset is located. IFRS 16 is expected to have a material impact on the Company’s consolidated statement of financial position. The Company is in the process of finalizing its assessment, and based on current estimates it expects to recognize right-of-use assets in the range of $130 to $150 and corresponding lease obligations in the range of $140 to $160 , before taking into account the related deferred tax impact. Deferred rent liabilities under the existing standard will be adjusted to opening retained earnings. In April, 2019, the Company recorded additional right-of-use assets and lease obligations with an impact of between $55 and $65 for leases with a commencement date following the transition.

Business Combinations [Abstract]
Business combination	Business combination On November 1, 2018 , a newly incorporated subsidiary of the Company, Baffin Limited (“Baffin”), acquired the business of Baffin Inc. (the “Baffin Vendor”), a Canadian designer and manufacturer of performance outdoor and industrial footwear for total purchase consideration of $35.1 . Management determined that the assets and processes comprised a business and therefore accounted for the transaction as a business combination using the acquisition method of accounting. The aggregate purchase consideration for the acquired assets, net of the assumed liabilities is as follows: $ Cash 33.6 Issuance of 16,946 subordinate voting shares 1.5 Total purchase consideration 35.1 In connection with the business combination, a further amount of $3.0 is payable on November 1, 2020 to the Baffin Vendor and will be charged to expense over two years . The Company incurred acquisition-related costs of $1.3 as at March 31, 2019 which are recorded in selling, general and administrative expenses. Assets acquired and liabilities assumed have been recorded at their fair values at the date of acquisition are as follows: $ Trade receivables 12.2 Inventories 15.9 Other current assets 0.3 Property, plant and equipment 2.5 Intangible assets Brand 2.5 Technology 2.2 Goodwill 7.8 Accounts payable and accrued liabilities (8.3 ) Total assets acquired, net of liabilities assumed 35.1 The fair values of working capital balances, other than inventories, have been measured at their book values at the date of acquisition, which approximate their fair values. The fair value of inventories has been measured at net realizable value, less costs to sell. The fair value of property, plant and equipment was based on management’s assessment of the acquired assets’ condition, as well as an evaluation of the current market value for such assets. In addition, the Company considered the length of time over which the economic benefit of these assets is expected to be realized and estimated the useful life of such assets as of the acquisition date. Identifiable intangible assets acquired consist of brand and technology. The fair value of the brand was $2.5 , measured using the relief-from-royalty approach. The fair value of technology was $2.2 , measured using the replacement cost method. Under this method, the technology is valued based upon the costs the Company would incur to develop a similar asset. The Company considered the length of time over which the economic benefits of these assets is expected to be realized and estimated the useful life of such assets accordingly as at the acquisition date. Specifically, the brand is considered to have an indefinite life; accordingly, it will be assessed for impairment annually or earlier if there are indicators of impairment. Technology is considered to have a useful life of 5 years and is being amortized on a straight-line basis. The excess of the purchase consideration over the fair value of the identifiable assets acquired has been accounted for as goodwill. Goodwill is mainly attributable to the expected future growth potential of the footwear business and is deductible for tax purposes. The results of operations have been consolidated with those of the Company from the date of acquisition including the results from the wholesale business in the wholesale operating segment and the e-commerce business in the Direct-to-Consumer operating segment. Pro forma disclosures as if Baffin was acquired at the beginning of the fiscal year have not been presented as they are not considered material to these financial statements. The controlling shareholder of the Baffin Vendor is employed as a member of key management subsequent to the acquisition. Transactions with the Baffin Vendor and other affiliates in connection with the acquisition and subsequently (including lease of premises and other operating costs) are related party transactions (note 20 ).

Operating Segments [Abstract]
Segment information	Segment information The Company has two reportable operating segments: Wholesale and Direct-to-Consumer. The Company measures each reportable operating segment’s performance based on revenue and segment operating income, which is the profit metric utilized by the Company’s chief operating decision maker, who is the President and Chief Executive Officer, for assessing the performance of operating segments. Neither reportable operating segment is reliant on any single external customer. Selling, general and administrative expenses not directly associated with the Wholesale or Direct-to-Consumer segments (unallocated) relate to the cost of marketing expenditures to build brand awareness across all segments, corporate costs in support of manufacturing operations, other corporate costs and foreign exchange gains and losses not specifically associated with segment operations. The Company does not report total assets or total liabilities based on its reportable operating segments. 2019 Wholesale Direct-to-Consumer Unallocated Total $ $ $ $ Revenue 399.2 431.3 — 830.5 Cost of sales 207.0 106.7 — 313.7 Gross profit 192.2 324.6 — 516.8 Selling, general and administrative expenses 43.0 90.0 169.1 302.1 Depreciation and amortization — — 18.0 18.0 Operating income 149.2 234.6 (187.1 ) 196.7 Net interest and other finance costs 14.2 Income before income taxes 182.5 2018 Wholesale Direct-to-Consumer Unallocated Total $ $ $ $ Revenue 336.2 255.0 — 591.2 Cost of sales 178.4 65.2 — 243.6 Gross profit 157.8 189.8 — 347.6 Selling, general and administrative expenses 37.2 55.1 107.8 200.1 Depreciation and amortization — — 9.4 9.4 Operating income 120.6 134.7 (117.2 ) 138.1 Net interest and other finance costs 12.9 Income before income taxes 125.2 2017 Wholesale Direct-to-Consumer Unallocated Total $ $ $ $ Revenue 288.6 115.2 — 403.8 Cost of sales 163.5 28.2 — 191.7 Gross profit 125.1 87.0 — 212.1 Selling, general and administrative expenses 30.7 27.5 106.8 165.0 Depreciation and amortization — — 6.6 6.6 Operating income 94.4 59.5 (113.4 ) 40.5 Net interest and other finance costs 10.0 Income before income taxes 30.5 The Company determines the geographic location of revenue based on the location of its customers. 2019 2018 2017 Revenue by geography: $ $ $ Canada 293.3 228.8 155.1 United States 251.1 184.2 131.9 Rest of World 286.1 178.2 116.8 830.5 591.2 403.8

Earnings per share [abstract]
Earnings per share	Earnings per share Basic earnings per share amounts are calculated by dividing net income for the period attributable to ordinary equity holders by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share amounts are calculated by dividing net income attributable to ordinary equity holders by the weighted average number of ordinary shares outstanding during the period plus the weighted average number of ordinary shares, if any, that would be issued on exercise of stock options and settlement of RSUs (note 18 ). Certain performance-vested exit event options issued under the Company’s Legacy Plan (note 18 ) became exercisable into subordinate voting shares upon the closing of a qualifying liquidity event or sale of shares. Such instruments are not considered dilutive until the occurrence of the event that would result in exercise and are excluded from the determination of diluted earnings per share prior to the occurrence of an exit event. The completion of the public share offering on March 21, 2017 and the secondary offering on July 5, 2017 each represent exit events, and performance-vested exit event options that became exercisable on each date are included in the calculation of diluted earnings per share from the date of the exit event that satisfies the contingent performance conditions. As of July 5, 2017, all exit event conditions have been met, and no outstanding options are subject to exit event conditions. 2019 2018 2017 $ $ $ Net income 143.6 96.1 21.6 Weighted average multiple and subordinate voting shares outstanding 109,422,574 107,250,039 100,262,026 Weighted average number of shares on exercise of stock options and settlement of RSUs 2,345,010 4,269,199 1,761,170 Diluted weighted average number of multiple and subordinate voting shares outstanding 111,767,584 111,519,238 102,023,196 Earnings per share Basic $ 1.31 $ 0.90 $ 0.22 Diluted $ 1.28 $ 0.86 $ 0.21

For the years ended March 31, 2019 and 2018, the cost of intangible assets in progress in the table above has been disclosed separately. Comparative figures for the year ended March 31, 2017 have been reclassified to correspond with the presentation adopted in the current year. Indefinite life intangible assets Indefinite life intangible assets recorded by the Company are comprised of the Canada Goose and Baffin brand names and domain name associated with the Company’s website. The Company expects to renew the registration of the brand names, and domain names at each expiry date indefinitely, and expects these assets to generate economic benefit in perpetuity. As such, the Company assessed these intangibles to have indefinite useful lives. The Company completed its annual impairment tests in 2019 and 2018 for indefinite life intangible assets and concluded that there was no impairment. Key Assumptions The key assumptions used to calculate the value-in-use (VIU) are consistent with the assumptions used to calculate VIU for goodwill (note 13 ).

Goodwill	Goodwill Goodwill arising from business combinations is as follows: 2019 2018 $ $ Opening balance 45.3 45.3 Business combination (note 5) 7.8 — Goodwill 53.1 45.3 The Company completed its annual impairment tests in 2019 and 2018 for goodwill and concluded that there was no impairment. Key Assumptions The key assumptions used to calculate the VIU are those regarding discount rate, revenue and gross margin growth rates, sales channel mix, and growth in selling, general and administrative expenses. These assumptions are considered to be Level 3 in the fair value hierarchy. The goodwill impairment tests resulted in excess of recoverable value over carrying value of at least 30.8% for each CGU. Because the VIU amount exceeds the asset’s carrying amount, the asset is not impaired and the fair value less costs of disposition has not been calculated. Cash flow projections were discounted using the Company’s weighted average cost of capital, determined to be 9.25% based on a risk-free rate, an equity risk premium adjusted for betas of comparable publicly traded companies, an unsystematic risk premium, country risk premium, country-specific risk premium, a cost of debt based on comparable corporate bond yields and the capital structure of the Company.

Other Provisions, Contingent Liabilities And Contingent Assets [Abstract]
Provisions	Provisions Provisions consist primarily of amounts recorded with respect to customer warranty obligations, terminations of sales agents and distributors, sales returns, and asset retirement obligations. The provision for warranty claims represents the present value of management’s best estimate of the future outflow of economic resources that will be required under the Company’s obligations for warranties under sale of goods, which may include repair or replacement of previously sold products. The estimate has been made on the basis of historical warranty trends and may vary as a result of new materials, altered manufacturing processes or other events affecting product quality and production. The sales contract provision relates to management’s estimated cost of the departure of certain third-party dealers and distributors. Sales returns relate primarily to goods sold through the Direct-to-Consumer sales channel which have a limited right of return (typically within 30 days), or exchange only, in certain jurisdictions. The return period is extended during the holiday shopping period to accommodate a higher volume of activity and purchases given as gifts.

Disclosure of detailed information about financial instruments [abstract]
Long-term debt	Long-term debt Revolving facility The Company has an agreement with a syndicate of lenders for a senior secured asset-based revolving facility in the amount of $200.0 with an increase in commitments to $250.0 during the peak season (June 1 - November 30), a revolving credit commitment comprising a letter of credit commitment in the amount of $25.0 , with a $5.0 sub-commitment for letters of credit issued in a currency other than Canadian dollars, U.S. Dollars or Euros, and a swingline commitment for $25.0 . The revolving facility matures on June 3, 2021. Amounts owing under the revolving facility can be drawn in Canadian dollars, U.S. dollars, Euros or other currencies. Amounts owing under the revolving facility may be borrowed, repaid and re-borrowed for general corporate purposes. The revolving facility has multiple interest rate charge options that are based on the Canadian prime rate, Bankers’ Acceptance rate, the lenders’ Alternate Base Rate, European Base Rate, LIBOR rate, or EURIBOR rate plus an applicable margin, with interest payable quarterly. The Company has pledged substantially all of its assets as collateral for the revolving facility. The revolving facility contains financial and non-financial covenants which could impact the Company’s ability to draw funds. At March 31, 2019 and during the year, the Company was in compliance with all covenants. As at March 31, 2019 and 2018 , the Company had repaid all amounts owing on the revolving facility and related deferred financing charges in the amounts of $1.2 and $1.7 , respectively, are included in other long-term liabilities. The Company has unused borrowing capacity available under the revolving facility of $165.5 as at March 31, 2019 ( 2018 - $97.8 ). As at March 31, 2019 , the Company had letters of credit outstanding under the revolving facility of $1.2 ( 2018 - $0.6 ). Term loan The Company has a senior secured loan agreement with a syndicate of lenders that is secured on a split collateral basis alongside the revolving facility , with an aggregate principal amount owing as at March 31, 2019 of $152.4 (US $113.8 ) ( 2018 - $146.6 (US $113.8 )). The term loan bears interest at a rate of LIBOR plus an applicable margin of 4.00% payable quarterly or at the end of the then current interest period (whichever is earlier) in arrears, provided that LIBOR may not be less than 1.00% . The term loan matures on December 2, 2021. Amounts owing under the term loan may be repaid at any time without premium or penalty, but once repaid may not be reborrowed. The Company has pledged substantially all of its assets as collateral for the term loan. The term loan contains financial and non-financial covenants which could impact the Company’s ability to draw funds. As at March 31, 2019 and during the year, the Company was in compliance with all covenants. As the term loan is denominated in U.S. dollars, the Company remeasures the outstanding balance and accrued interest at each balance sheet date. The amount outstanding with respect to the term loan is as follows: 2019 2018 $ $ Term loan 152.4 146.6 Less unamortized portion of: Original issue discount (2.4 ) (3.1 ) Deferred financing fees (0.9 ) (1.2 ) Embedded derivative (0.5 ) (0.7 ) Revaluation for interest rate modification (3.4 ) (4.5 ) 145.2 137.1 The Company recognized the fair value of the embedded derivative liability related to the interest rate floor of $1.4 at the inception of the term loan . The derivative will be remeasured at each reporting period and is included in other long-term liabilities. As at March 31, 2019 , the value is $0.1 ( 2018 - $0.2 ). On March 21, 2017, the Company prepaid $65.0 (US $48.8 ) of the outstanding principal balance of the term loan. After the prepayment, the applicable margin decreased from 5.00% to 4.00% which gave rise to a decrease in the fair value of the term loan that is being amortized over the remaining term. During the year ended March 31, 2018 , the term loan lenders syndicated their commitments under the loan agreement to a new group of lenders; the Company’s obligations under the loan agreement are substantially unchanged, and the syndication had no accounting impact. The Company incurred financing costs of $0.3 in connection with the syndication transaction, which will be amortized over the remaining term of the loan using the effective interest rate method. Hedging transactions on term loan On October 18, 2017, the Company entered into derivative transactions to hedge a portion of its exposure to foreign currency exchange risk and interest rate risk related to its term loan liability denominated in U.S. dollars. The Company entered into a long-dated forward exchange contract to buy $75.0 , or $59.4 in equivalent U.S. dollars as measured on the trade date, to fix the foreign exchange risk on term loan borrowings over the term to maturity (December 2, 2021). Unrealized gains and losses in the fair value of the forward contract are recognized in selling, general and administrative expenses in the statement of income. The Company also entered into a cross-currency swap by selling $50.0 , $40.0 in equivalent U.S. dollars, floating rate debt bearing interest at LIBOR plus 4.00% as measured on the trade date, and receiving $50.0 fixed rate debt bearing interest at a rate of 5.80% . This cross-currency swap has been designated at inception and is accounted for as a cash flow hedge, and to the extent that the hedge is effective, unrealized gains and losses are included in other comprehensive income until reclassified to the statement of income as the hedged interest payments and principal repayments (or periodic remeasurements) impact net income. Concurrently, the Company entered into a second cross-currency swap by selling the $50.0 fixed rate debt bearing interest at a rate of 5.80% and receiving $50.0 , or €34.0 in equivalent Euro-denominated fixed rate debt bearing interest at a rate of 3.84% . This cross-currency swap has been designated and is accounted for as a hedge of the net investment in its European subsidiary. Hedges of net investments are accounted for similarly to cash flow hedges, with unrealized gains and losses included in other comprehensive income. Amounts included in other comprehensive income are reclassified to net income in the period when the foreign operation is disposed of or sold. Net interest and other finance costs Net interest and other finance costs consist of the following: 2019 2018 2017 $ $ $ Interest expense Revolving facility 2.4 2.3 2.4 Term loan 11.7 10.4 4.9 Credit facility — — 0.4 Subordinated debt — — 3.8 Other — — 0.3 Standby fees 0.6 0.4 0.2 Write off deferred financing costs on repayment of debt — — 3.9 Revaluation of term loan for change in interest rate — — (5.9 ) Interest expense and other finance costs 14.7 13.1 10.0 Interest income (0.5 ) (0.2 ) — Net interest and other finance costs 14.2 12.9 10.0

Share-based payment arrangements [Abstract]
Share-based payments	Share-based payments The Company has issued stock options to purchase subordinate voting shares under its incentive plans, prior to the public share offering on March 21, 2017, the Legacy Plan, and subsequently, the Omnibus Plan. All options are issued at an exercise price that is not less than market value at the time of grant and expire ten years after the grant date. Legacy Plan Under the terms of the Legacy Plan, options were granted to certain employees of the Company which are exercisable to purchase subordinate voting shares. The options vest contingent upon meeting the service, performance goals and exit event conditions of the Legacy Plan. a) Service-vested options Service-vested options are subject to the employee’s continuing employment and generally are scheduled to vest 40% on the second anniversary of the date of grant, 20% on the third anniversary, 20% on the fourth anniversary and 20% on the fifth anniversary. b) Performance-vested and exit event options Performance-vested options that are tied to an exit event become eligible to vest pro rata on the same schedule as service-vested options, but do not vest until the exit event has occurred. An exit event is triggered based on a target realized rate of return on invested capital. Other performance-vested options vest based on measurable performance targets that do not involve an exit event. Performance-vested options are subject to the employee’s continued employment. On each vesting date, service-vested options vest, and performance-vested exit event options become eligible to vest upon the occurrence of an exit event. The completion of the public share offering on March 21, 2017 and the secondary offering on July 5, 2017 each represent exit events such that options that were eligible to vest became vested. As of July 5, 2017, all exit event conditions have been met, and no outstanding options are subject to exit event conditions. No options will be issued under the Legacy Plan subsequent to the public share offering. Omnibus Plan Under the terms of the Omnibus Plan, options are granted to certain employees of the Company which are exercisable to purchase subordinate voting shares. The options vest over four years contingent upon meeting the service conditions of the Omnibus Plan, 25% on each anniversary of the date of grant.

The RSUs are treated as equity instruments for accounting purposes. We expect that vested RSUs will be paid at settlement through the issuance of one subordinate voting share per RSU. The RSUs vest over a period of three years , a third on each anniversary of the date of grant. Fair value is determined based on the market value of the shares at the time of grant. Subordinate voting shares, to a maximum of 6,668,247 shares, have been reserved for issuance under equity incentive plans to select employees of the Company, with vesting contingent upon meeting the service, performance goals and other conditions of the Plan. Accounting for share-based awards For the year ended March 31, 2019 , the Company recorded $3.8 as contributed surplus and compensation expense for stock options and RSUs ( 2018 - $2.0 , 2017 - $3.3 ). In addition, cash compensation in the amount of $2.6 was paid to settle stock options cancelled on employee termination in the year ended March 31, 2017 . Share-based compensation expense is included in selling, general and administrative expenses. The assumptions used to measure the fair value of options granted under the Black Scholes option pricing model at the grant date were as follows: 2019 2018 Weighted average stock price valuation $ 79.59 $ 31.91 Weighted average exercise price $ 79.59 $ 31.91 Risk-free interest rate 1.82 % 1.34 % Expected life in years 5 5 Expected dividend yield — % — % Volatility 40 % 40 % Weighted average fair value of options issued $ 32.68 $ 9.80

Financial Instruments [Abstract]
Financial risk management objectives and policies	Financial risk management objectives and policies The Company’s primary risk management objective is to protect the Company’s assets and cash flow, in order to increase the Company’s enterprise value. The Company is exposed to capital management risk, market risk, credit risk, and liquidity risk. The Company’s senior management and Board of Directors oversee the management of these risks. The Board of Directors reviews and agrees policies for managing each of these risks which are summarized below. Capital management The Company manages its capital, which consists of equity (subordinate voting shares and multiple shares voting shares) and long-term debt (the revolving facility and the term loan), with the objectives of safeguarding sufficient net working capital (1) over the annual operating cycle and providing sufficient financial resources to grow operations to meet long-term consumer demand. Management targets a ratio of trailing twelve months adjusted EBITDA (1) to net debt (1) , and trailing twelve months net working capital to revenue, reflecting the seasonal borrowing requirements while net working capital builds through the second fiscal quarter. The Board of Directors monitors the Company’s capital management on a regular basis. The Company will continually assess the adequacy of the Company’s capital structure and capacity and make adjustments within the context of the Company’s strategy, economic conditions, and the risk characteristics of the business. (1) Adjusted earnings before depreciation, amortization, interest and taxes, net working capital and net debt are non-IFRS measures. Market risk Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. Market prices comprise interest rate risk and foreign currency risk. Interest rate risk The Company is exposed to interest rate risk primarily related to the effect of interest rate changes on borrowings outstanding under the revolving facility and the term loan. As at March 31, 2019 , the Company had repaid all amounts owing on the revolving facility. The amount outstanding under the term loan was $152.4 which currently bears interest at 6.50% . Based on the weighted average amount of outstanding borrowings under the revolving facility during the year-ended March 31, 2019 , a 1.00% increase in the average interest rate on our borrowings under the revolving facility would have increased interest expense by $0.6 ( 2018 - $0.6 ) in the period. Correspondingly, a 1.00% increase in the rate on the term loan would have increased interest expense by an additional $1.5 ( 2018 - $1.5 ). Interest rate risk on the term loan is partially mitigated by cross-currency swap hedges. The impact on future interest expense because of future changes in interest rates will depend largely on the gross amount of borrowings at that time. Foreign exchange risk Foreign exchange risk in operating cash flows The Company’s consolidated financial statements are expressed in Canadian dollars, but a substantial portion of the Company’s revenues, inventory purchases and expenses are denominated in other currencies, principally U.S. dollars, Euros, British Pounds Sterling, Swiss Francs, Chinese yuan, Hong Kong dollars and Swedish krona. The Company has entered into forward foreign exchange contracts to reduce the foreign exchange risk associated with revenues, purchases, and expenses denominated in these currencies. Beginning in fiscal 2017, certain forward foreign exchange contracts were designated at inception and accounted for as cash flow hedges with respect to expected activity in the 2018 fiscal year. The operating hedge programs for the fiscal years ending March 31, 2020 and March 31, 2021 was initiated during the fourth quarter of the 2019 fiscal year. During the year ended March 31, 2019 , an unrealized loss in the fair value of derivatives designated as cash flow hedges in the amount of $3.9 (net of tax recovery of $0.8 ) has been recorded in other comprehensive income ( 2018 - an unrealized loss of $1.4 net of tax recovery of $0.5 ). During the year ended March 31, 2019 , an unrealized gain of $3.7 ( 2018 - $0.1 ) on forward exchange contracts that are not treated as hedges has been recorded selling, general and administrative expenses in the statement of income. During the year ended March 31, 2019 , a gain of $4.5 was reclassified from other comprehensive income to selling, general and administrative expenses ( 2018 - a loss of $0.3 ). During the year ended March 31, 2019 , a loss of $6.5 was recorded in revenue and a gain of $1.0 was recorded in inventories. Foreign currency contracts outstanding as at March 31, 2019 related to operating cash flows are: (in millions) Contract Amount Primary Currency Forward contract to purchase Canadian dollars US$ 155.0 U.S. dollars € 72.9 Euros Forward contract to sell Canadian dollars US$ 65.9 U.S. dollars € 32.7 Euros Forward contract to purchase Euros CHF 2.1 Swiss francs CNY 588.5 Chinese yuan £ 16.0 British Pounds sterling HKD 121.6 Hong Kong dollar SEK 10.7 Swedish Krona Forward contract to sell Euros CHF 11.4 Swiss francs £ 1.0 British Pounds sterling Revenues and expenses of all foreign operations are translated into Canadian dollars at the foreign currency exchange rates that approximate the rates in effect at the dates when such items are recognized. Appreciating foreign currencies relative to the Canadian dollar, to the extent they are not hedged, will positively impact operating income and net income, while depreciating foreign currencies relative to the Canadian dollar will have the opposite impact. Foreign exchange risk on long-term debt The Company is exposed to fluctuations in the amount owing on the revolving facility and the term loan that are denominated in U.S. dollars. A $0.01 increase (decrease) in the value of the U.S. dollar relative to the Canadian dollar would result in a gain (loss) of $1.1 in income before taxes, based on the balances outstanding as at March 31, 2019 ( 2018 - $1.1 ). Appreciating foreign currencies relative to the Canadian dollar, to the extent they are not hedged, will positively impact operating income and net income, while depreciating foreign currencies relative to the Canadian dollar will have the opposite impact. On October 18, 2017, the Company entered into derivative transactions to hedge a portion of its exposure to foreign currency exchange risk on principal and interest payments on its term loan liability denominated in U.S. dollars (note 16 ). During the year ended March 31, 2019 , an unrealized gain of $2.9 in the fair value of the long-dated forward exchange contract related to a portion of the term loan balance has been recognized in selling, general and administrative expenses in the statement of income ( 2018 - unrealized gain of $0.3 ). An unrealized gain of $0.7 (net of tax expense of $0.2 ) on the cross-currency swap that is designated as a cash flow hedge has been recorded in other comprehensive income ( 2018 - unrealized gain of $1.5 , net of tax expense of $0.5 ). An unrealized loss of $0.4 was reclassified from other comprehensive income to selling, general and administrative expenses ( 2018 - unrealized loss of $1.1 ). During the year ended March 31, 2019 , the Company has recognized in other comprehensive income an unrealized gain of $3.5 (net of tax expense of $1.2 ) in the fair value of the Euro-denominated cross-currency swap that is designated as a hedge of the Company's net investment in its European subsidiary ( 2018 - unrealized loss of $3.5 , net of tax expense of $1.2 ). Credit risk Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. Credit risk arises from the possibility that certain parties will be unable to discharge their obligations. The Company has a significant number of customers which minimizes the concentration of credit risk. The Company does not have any customers which account for more than 10% of sales or accounts receivable. The Company has entered into an agreement with a third party who has insured the risk of loss for up to 87.8% of accounts receivable from certain designated customers based on a total deductible of less than $0.1 , to a maximum of $30.0 per year. As at March 31, 2019 , accounts receivable totaling approximately $14.1 ( March 31, 2018 - $8.1 ) were insured under this agreement. In addition, the Company routinely assesses the financial strength of its customers and, as a consequence, believes that its accounts receivable credit risk exposure is limited. Customer deposits are received in advance from certain customers for seasonal orders, and applied to reduce accounts receivable when goods are shipped. Credit terms are normally sixty days for seasonal orders, and thirty days for re-orders. The aging of trade receivables is as follows: Total Past due Current < 30 days 31-60 days > 60 days $ $ $ $ $ Trade accounts receivable 19.7 12.9 4.7 0.5 1.6 Credit card receivables 1.6 1.6 — — — March 31, 2019 21.3 14.5 4.7 0.5 1.6 Trade accounts receivable 9.7 4.3 2.8 1.0 1.6 Credit card receivables 3.0 3.0 — — — March 31, 2018 12.7 7.3 2.8 1.0 1.6 Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s approach to managing liquidity is to ensure, as far as possible, that it will always have sufficient liquidity to satisfy the requirements for business operations, capital expenditures, debt service and general corporate purposes, under normal and stressed conditions. The primary source of liquidity is funds generated by operating activities; the Company also relies on the asset based revolving facility as a source of funds for short term working capital needs. The Company continuously reviews both actual and forecasted cash flows to ensure that the Company has appropriate capital capacity. The following table summarizes the amount of contractual undiscounted future cash flow requirements as at March 31, 2019 : 2020 2021 2022 2023 2024 Thereafter Total Contractual obligations $ $ $ $ $ $ $ Accounts payable and accrued liabilities 110.4 — — — — — 110.4 Revolving facility — — — — — — — Term loan — — 152.4 — — — 152.4 Note payable (note 5) — 3.0 — — — — 3.0 Interest commitments relating to long-term debt (1) 9.9 9.9 6.6 — — — 26.4 Operating leases 32.4 36.0 34.5 32.9 30.6 87.0 253.4 Pension obligation — — — — — 2.2 2.2 (1) Interest commitments are calculated based on the loan balance and the interest rate payable on the Term Loan of 6.50% as at March 31, 2019 .

Corporate Information And Statement Of IFRS Compliance [Abstract]
Statement of compliance	Statement of compliance The accompanying consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).
Basis of presentation	Basis of presentation These consolidated financial statements have been prepared on the historical cost basis except for the following items, which are recorded at fair value: • financial instruments, including derivative financial instruments, at fair value in other comprehensive income and through profit or loss, and • initial recognition of assets acquired and liabilities assumed in a business combination. The significant accounting policies set out below have been applied consistently in the preparation of the consolidated financial statements for all periods presented, with the exception of transitional provisions applied in adopting new accounting standards (note 4).
Functional and presentation currency	These consolidated financial statements are presented in Canadian dollars, the Company’s functional and presentation currency.
Basis of consolidation	Basis of consolidation Subsidiaries are entities controlled by the Company. Control exists when the Company has power over, exposure or rights to variable returns from the Company’s involvement with the entity, and the ability to use its power over the entity to affect the amount of the Company’s returns. The financial accounts and results of subsidiaries are included in the consolidated financial statements of the Company from the date that control commences until the date that control ceases.
Operating segments	Operating segments An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Company’s other components, and for which discrete financial information is available. Segment operating results are reviewed regularly to make decisions about resources to be allocated to the segment and assess its performance. The Company classifies its business in two operating and reportable segments: Wholesale and Direct-to-Consumer. The Wholesale business comprises sales made to a mix of functional and fashionable retailers, including major luxury department stores, outdoor specialty stores, individual shops, and to international distributors. The Direct-to-Consumer business comprises sales through our country-specific e-commerce platforms and Company-owned retail stores located in luxury shopping malls and high street locations.
Foreign currency translation	Foreign currency translation Functional and presentation currency Items included in the consolidated financial statements of the Company’s subsidiaries are measured in the functional currency, which is using the currency of the primary economic environment in which each entity operates. Transactions and balances Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation when items are remeasured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the changes at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the statement of income in selling, general and administrative expenses, except when included in other comprehensive income for qualifying cash flow and net investment hedges. Foreign operations The Company’s foreign operations are principally conducted through Canada Goose US, Inc., Canada Goose International AG,and CG (Shanghai) Trading Co. Ltd. The assets and liabilities of subsidiaries whose functional currency is not the Canadian dollar are translated into the functional currency of the Company using the exchange rate at the reporting date. Revenues and expenses are translated at exchange rates prevailing at the transaction date. The resulting foreign exchange translation differences are recorded as a currency translation adjustment in other comprehensive income.
Seasonality	Seasonality We experience seasonal fluctuations in our revenue and operating results and historically have realized a significant portion of our wholesale revenue and operating income for the year during our second and third fiscal quarters and Direct-to-Consumer revenue and operating income in our third and fourth fiscal quarters. Thus, lower-than-expected net revenue in these periods could have an adverse impact on our annual operating results. Working capital requirements typically increase during the first and second quarters of the fiscal year as inventory builds to support peak shipping and selling periods and, accordingly, typically decrease during the third and fourth quarter of the fiscal year as inventory is sold and trade receivables are converted to cash. After retail stores are opened, operating costs in our Direct-to-Consumer channel are consistent over the year while revenue and related cash collections fluctuate. Borrowings on our revolving facility have historically increased over the first and second quarters and are repaid in the third quarter of the fiscal year. Cash flows from operating activities are typically highest in the third and fourth quarters of the fiscal year due to the timing of collection of wholesale trade receivables and revenue in the Direct-to-Consumer channel during that period and increased cash inflows from the peak selling season.
Revenue recognition	Revenue recognition Revenue comprises of the consideration to which the Company expects to be entitled in exchange for the sale of goods in the ordinary course of the Company’s activities. Revenue is presented net of sales tax, estimated returns, sales allowances, and discounts. The Company recognizes revenue when the Company has agreed terms with its customers, the contractual rights and payment terms have been identified, the contract has commercial substance, it is probable that consideration will be collected by the Company, and when specific criteria for transfer of control to the customer have been met for each of the Company’s activities, as described below. i) Wholesale Wholesale revenue comprises sales of the Company's products to third-party resellers (which includes international distributors and retailers). Wholesale revenue from the sale of goods is recognized, net of an estimated provision for sales returns, discounts and allowances, when the control of the goods has been transferred to the reseller, which depends on the precise terms of the agreement with each reseller. The Company, at its discretion, may cancel all or a portion of any firm wholesale sales order. The Company is therefore obligated to return any prepayments or deposits made by resellers for which the product is not provided. All advance payments are therefore included in accrued liabilities in the statement of financial position. ii) Direct-to-Consumer Direct-to-Consumer revenue consists of sales through the Company’s e-commerce operations and Company-owned retail stores. Sales through e-commerce operations are recognized upon estimated delivery of the goods to the customer, net of an estimated provision for sales returns, when control of the goods has transferred from the Company to the customer. Sales through our Company-owned retail stores are recognized upon delivery to the customer at the point of sale, net of an estimated provision for sales returns. It is the Company’s policy to sell merchandise through the Direct-to-Consumer channel with a limited right to return, typically within 30 days. Accumulated experience is used to estimate and provide for such returns. The Company’s warranty obligation is to provide an exchange or repair for manufacturing defective products under the standard warranty terms and conditions. The warranty obligation is recognized as a provision when goods are sold.
Business combinations	Business combinations Acquisitions of businesses are accounted for using the acquisition method as of the acquisition date, which is the date when control is transferred to the Company. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition date fair values of the assets transferred, liabilities incurred by the Company and the equity interests issued by the Company in exchange for control of the acquiree. Transaction costs that the Company incurs in connection with a business combination are recognized in the statement of income as incurred. Goodwill is measured as the excess of the sum of the fair value of consideration transferred over the net of the acquisition date amounts of the identifiable assets acquired and the liabilities assumed. When the consideration transferred in a business combination includes contingent consideration, the contingent consideration is measured at its acquisition date fair value. Contingent consideration is remeasured at subsequent reporting dates at its fair value, and the resulting gain or loss recognized in the statement of income.
Earnings per share	Earnings per share Basic earnings per share is calculated by dividing net income for the year attributable to ordinary equity holders of the common shares by the weighted average number of multiple and subordinated voting shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to ordinary equity holders of the Company by the weighted average number of multiple and subordinated voting shares outstanding during the year plus the weighted average number of subordinate shares that would be issued on the exercise of all stock options and settlement of restricted share units (“RSU”).
Income taxes	Income taxes Current and deferred income taxes are recognized in the consolidated statements of income and other comprehensive income, except when it relates to a business combination, or items recognized in equity or in other comprehensive income. Current income tax Current income tax is the expected income tax payable or receivable on the taxable income or loss for the period, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to income tax payable in respect of previous years.
Deferred income tax	Deferred income tax Deferred income tax is provided using the liability method for temporary differences at the reporting date between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Deferred income tax is measured using enacted or substantively enacted income tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. A deferred tax asset is recognized for unused income tax losses and credits to the extent that it is probable that future taxable income will be available against which they can be utilized. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable income will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable income will allow the deferred tax asset to be recovered. Deferred income tax relating to items recognized outside profit or loss is recognized outside profit or loss. Deferred tax items are recognized in correlation to the underlying transaction either in other comprehensive income or directly in equity. Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred tax relates to the same taxable entity and the same taxation authority. Deferred income tax is provided on temporary differences arising on investments in subsidiaries, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future.
Cash	Cash Cash consists of cash and cash equivalents, including cash on hand, deposits in banks, and short-term deposits with maturities of less than 3 months. The Company uses the indirect method of reporting cash flow from operating activities.
Trade receivables	Trade receivables Trade receivables, including credit card receivables, consist of amounts owing where we have extended credit to customers on product sales and are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, less expected credit loss and sales allowances. The allowance for expected credit loss is recorded against trade receivables and is based on historical experience.
Inventories	Inventories Raw materials, work-in-process and finished goods are valued at the lower of cost and net realizable value. Cost is determined using the weighted average cost method. The cost of work-in-process and finished goods inventories include the cost of raw materials and an applicable share of the cost of labour and fixed and variable production overhead, including depreciation of property, plant and equipment used in the production of finished goods and design costs, and other costs incurred in bringing the inventories to their present location and condition. The Company estimates net realizable value as the amount at which inventories are expected to be sold, taking into consideration fluctuations in selling prices due to seasonality, less estimated costs necessary to complete the sale. Inventories are written down to net realizable value when the cost of inventories is estimated to be unrecoverable due to obsolescence, damage or declining selling prices. Inventory is adjusted to reflect estimated loss (“shrinkage”) incurred since the last inventory count. Shrinkage is based on historical experience. When circumstances that previously caused inventories to be written down below cost no longer exist or when there is clear evidence of an increase in realizable value, the amount of the write-down previously recorded is reversed. Storage costs, indirect administrative overhead and certain selling costs related to inventories are expensed in the period that these costs are incurred.
Property, plant and equipment	Property, plant and equipment Property, plant and equipment is stated at cost, net of accumulated depreciation and any accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of the asset, including costs incurred to prepare the asset for its intended use and capitalized borrowing costs, when the recognition criteria are met. The commencement date for capitalization of costs occurs when the Company first incurs expenditures for the qualifying assets and undertakes the required activities to prepare the assets for their intended use. Property, plant and equipment assets are depreciated on a straight-line basis over their estimated useful lives when the assets are available for use. When significant parts of a fixed asset have different useful lives, they are accounted for as separate components and depreciated separately. Depreciation methods and useful lives are reviewed annually and are adjusted for prospectively, if appropriate. Estimated useful lives are as follows: Asset Category Estimated Useful Life Plant equipment 10 years Computer hardware 5 years Leasehold improvements Lesser of the lease term or useful life of the asset Show displays 5 years Furniture and fixtures 3 to 15 years An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset, calculated as the difference between the net disposal proceeds and the carrying amount of the asset, is included in the statement of income when the asset is derecognized. The cost of repairs and maintenance of fixed assets is expensed as incurred and recognized in the statement of income. Property, plant and equipment are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, the entity will estimate the recoverable amount of the asset and record any impairment loss in the statement of income.
Intangible assets	Intangible assets Intangible assets acquired separately are measured on initial recognition at cost. The cost of an intangible asset acquired in a business combination is its fair value as at the date of acquisition. Following initial recognition, intangible assets with finite lives are carried at cost less any accumulated amortization and any accumulated impairment losses. Lease rights in connection with the opening of new Company-owned retail stores are recorded based on the amount paid. Lease rights have a definite useful life and are amortized on a straight-line basis over the term of the lease. An internally generated intangible asset is recorded for product development costs which are included within intellectual property. Product development costs are incurred in the design, production and testing of new products where the technical feasibility of commercial manufacturing and sale of the product has been demonstrated. The useful lives of intangible assets are assessed as either finite or indefinite. Asset Category Estimated Useful Life Brand name Indefinite Domain name Indefinite ERP software 7 years Computer software 5 years Lease rights Lease term Intellectual property 1 to 8 years Customer lists 4 years Intangible assets with indefinite useful lives comprise of the Canada Goose and Baffin brand names (note 5 ) and domain name, which were acquired as part of an acquisition and were recorded at their estimated fair value. The brand names and domain name are considered to have an indefinite life based on a history of revenue and cash flow performance, and the intent and ability of the Company to support the brand with spending to maintain its value for the foreseeable future. The brand names and domain name are tested at least annually for impairment, at the cash-generating unit (“CGU”) level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis. Intangible assets with finite lives are amortized over the useful economic life on straight-line basis. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of income over its estimated useful life. An intangible asset is derecognized on disposal or when no future economic benefits are expected from its use. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are included in the statement of income when the asset is derecognized. Intangible assets are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, the entity will estimate the recoverable amount of the asset and record any impairment loss in the statement of income.
Goodwill	Goodwill Goodwill represents the difference between the purchase price of an acquired business and the Company’s share of the net identifiable assets acquired and liabilities assumed and any contingent liabilities assumed. It is initially recorded at cost and subsequently measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to CGUs based on the lowest level within the entity in which the goodwill is monitored for internal management purposes. The allocation is made to those CGUs that are expected to benefit from the business combination in which the goodwill arose. Any potential impairment of goodwill is identified by comparing the recoverable amount of a CGU to its carrying value. Goodwill is reduced by the amount of deficiency, if any. If the deficiency exceeds the carrying amount of goodwill, the carrying values of the remaining assets in the CGU are reduced by the excess on a pro-rata basis. The Company tests goodwill for impairment annually in the fourth quarter of the fiscal year. The recoverable amount of a CGU is the higher of the estimated fair value less costs of disposal or value-in-use of the CGU. In assessing value-in-use, the estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. The Company has determined that the goodwill contributes to the cash flows of seven CGUs (2018 - six CGUs).
Provisions	Provisions Provisions are recognized when the Company has a present obligation, legal or constructive, as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. Where the Company expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset but only when the reimbursement is virtually certain. The expense relating to any provision is presented in the statement of income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized in the statement of income. The provision for warranty returns relates to the Company’s obligation for defective goods sold to customers that have yet to be returned. Accruals for warranty returns are estimated on the basis of historical returns and are recorded so as to allocate them to the same period the corresponding revenue is recognized.
Employee future benefits	Employee future benefits The Company sponsors defined benefit pension plan membership, which is limited to certain employees of Canada Goose International AG and other subsidiaries who reside in Switzerland. The measurement date for the defined benefit pension plan is March 31 . The obligation associated with the Company’s defined benefit pension plan is actuarially valued using the projected unit credit method, management’s best estimate assumptions, salary escalation, inflation, life expectancy, and a current market discount rate. Assets are measured at fair value. The obligation in excess of plan assets is recorded as a liability. All actuarial gains or losses, net of tax, are recognized immediately through other comprehensive income.
Fair values	Fair values Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • In the principal market for the asset or liability, or • In the absence of a principal market, in the most advantageous market for the asset or liability. The Company uses valuation techniques that it believes are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 : inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: are unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above. There was no change in the valuation techniques applied to financial instruments during all periods presented. The following table describes the valuation techniques used in the determination of the fair values of financial instruments: Type Valuation Approach Cash, trade receivables, accounts payable and accrued liabilities The carrying amount approximates fair value due to the short term maturity of these instruments. Derivatives (included in other current assets, other long-term assets, accounts payable and accrued liabilities or other long-term liabilities) Specific valuation techniques used to value derivative financial instruments include: - Quoted market prices or dealer quotes for similar instruments; - Observable market information as well as valuations determined by external valuators with experience in the financial markets. Revolving facility and term loan The fair value is based on the present value of contractual cash flows, discounted at the Company’s current incremental borrowing rate for similar types of borrowing arrangements or, where applicable, market rates.
Financial instruments	Financial instruments Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the financial instrument. Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issuance of financial assets and financial liabilities (other than financial assets and financial liabilities classified at fair value through profit or loss) are added to, or deducted from, the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities classified at fair value through profit or loss are recognized immediately in profit or loss. Financial assets and financial liabilities are measured subsequently as described below. i) Non-derivative financial assets Non-derivative financial assets include cash and trade receivables which are measured at amortized cost. The Company initially recognizes receivables and deposits on the date that they are originated. The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. ii) Non-derivative financial liabilities Non-derivative financial liabilities include accounts payable, accrued liabilities, revolving facility, and term loan. The Company initially recognizes debt instruments issued on the date that they are originated. All other financial liabilities are recognized initially on the trade date at which the Company becomes a party to the contractual provisions of the instrument. Financial liabilities are recognized initially at fair value less any directly attributable transaction costs. Subsequent to initial recognition, these financial liabilities are measured at amortized cost using the effective interest method. The Company derecognizes a financial liability when its contractual obligations are discharged or cancelled or expire. iii) Derivative financial instruments Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at each reporting date. The method of recognizing the resulting gain or loss depends on whether the derivative is designated and effective as a hedging instrument. When a derivative financial instrument, including an embedded derivative, is not designated and effective in a qualifying hedge relationship, all changes in its fair value are recognized immediately in the statement of income; attributable transaction costs are recognized in the statement of income as incurred. The Company does not use derivatives for trading or speculative purposes. Embedded derivatives are separated from a host contract and accounted for separately if the economic characteristics and risks of the host contract and the embedded derivative are not closely related. iv) Hedge accounting The Company is exposed to the risk of currency fluctuations and has entered into currency derivative contracts to hedge its exposure on the basis of planned transactions. Where hedge accounting is applied, the criteria are documented at the inception of the hedge and updated at each reporting date. The Company documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking the hedging transactions. The Company also documents its assessment, at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The fair value of a hedging derivative is classified as a current asset or liability when the maturity of the hedged item is less than twelve months, and as a non-current asset or liability when the maturity of the hedged item is more than twelve months. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized, net of tax, in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the statement of income. Amounts accumulated in other comprehensive income are transferred to the statement of income in the periods when the hedged item affects net income. When a forecast transaction that is hedged results in the recognition of a non-financial asset or liability, such as inventory, the amounts are included in the measurement of the cost of the related asset or liability. The deferred amounts are ultimately recognized in the statement of income. Hedges of net investments are accounted for similarly to cash flow hedges, with unrealized gains and losses recognized, net of tax, in other comprehensive income. Amounts included in other comprehensive income are transferred to the statement of income in the period when the foreign operation is disposed of or sold.
Share-based payments	Share-based payments Share-based payments are valued based on the grant date fair value of these awards and the Company records compensation expense over the corresponding service period. The fair value of the share-based payments is determined using acceptable valuation techniques. The Company has issued stock options to purchase subordinate voting shares and RSUs under its equity incentive plans, prior to the public offering on March 21, 2017 (the “Legacy Plan”) and subsequently (the “Omnibus Plan”). Under the terms of the Legacy Plan, options were granted to certain employees of the Company with vesting contingent upon meeting the service, performance goals and exit event conditions of the Legacy Plan. There are two types of stock options: service-vested options are time based and generally vest over five years of service, and performance-based and exit event options vest upon attainment of performance conditions and the occurrence of an exit event. Under the terms of the Omnibus Plan, options are granted to certain executives of the Company with vesting, generally over four years , contingent upon meeting the service conditions of the Omnibus Plan. The compensation expense related to the options and RSUs is recognized ratably over the requisite service period, provided it is probable that the vesting conditions will be achieved and the occurrence of the exit event, if applicable, is probable.
Leases	Leases Operating lease payments net of any lease inducements are recognized as an expense in the statement of income on a straight-line basis over the lease term.
