Significant Accounting Policies [Abstract] |
Basis of measurement [Policy Text Block] | a) Basis of measurement The consolidated financial statements are prepared under the historical cost convention, except for the revaluation of certain financial assets at fair value (including derivative instruments).
Business combinations [Policy Text Block] | b) Business combinations On the acquisition of a business, the acquisition method of accounting is used whereby the purchase consideration is allocated to the identifiable assets, liabilities and contingent liabilities (identifiable net assets) of the business on the basis of the fair value at the date of acquisition. Provisional fair values allocated at a reporting date are finalized as soon as the relevant information is available, which period shall not exceed twelve months from the acquisition date and are adjusted to reflect the transaction as of the acquisition date. Any excess is treated as goodwill, and any discount is immediately recognized in the consolidated statement of loss and comprehensive loss. If control is obtained or lost as a result of a transaction, the identifiable net assets retained are recognized on the balance sheet at fair value and the difference between the fair value recognized and the carrying value as at the date of the transaction is recognized in the consolidated statement of loss. Acquisition costs are expensed as incurred. The Company recognizes any non-controlling interest in the acquiree on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interest's proportionate share of the recognized amounts of acquiree's identifiable net assets. The results of businesses acquired during the period are consolidated into the consolidated financial statements from the date on which control commences (generally at the closing date when the acquirer legally transfers the consideration).
Consolidation [Policy Text Block] | c) Consolidation The Company's financial statements consolidate the accounts of Osisko Gold Royalties Ltd and its subsidiaries. All intercompany transactions, balances and unrealized gains or losses from intercompany transactions are eliminated on consolidation. Subsidiaries are all entities over which the Company has the ability to exercise control. The Company controls an entity when the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to Osisko and are de-consolidated from the date that control ceases. Accounting policies of subsidiaries are consistent with the policies adopted by Osisko. The principal subsidiaries of the Company, all of which are wholly-owned, and their geographic locations at December 31, 2019 and 2018 were as follows:
Entity | Jurisdiction
Osisko Bermuda Limited | Bermuda
Barkerville Gold Mines Ltd.(i) | British Columbia
Coulon Mines Inc. | Canada
General Partnership Osisko James Bay | Québec
Osisko Mining (USA) Inc. | Delaware
(i) From November 21, 2019 (Note 7).
Foreign currency translation [Policy Text Block] | d) Foreign currency translation (i) Functional and presentation currency Items included in the financial statements of each consolidated entity and associate of the Company are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). The consolidated financial statements are presented in Canadian dollars, which is the functional currency of the parent Company. Assets and liabilities of the subsidiaries that have a functional currency other than the Canadian dollar are translated into Canadian dollars at the exchange rate in effect on the consolidated balance sheet date and revenues and expenses are translated at the average exchange rate over the reporting period. Gains and losses from these translations are recognized as currency translation adjustment in other comprehensive income or loss. (ii) Transactions and balances Foreign currency transactions, including revenues and expenses, are translated into the functional currency at the rate of exchange prevailing on the date of each transaction or valuation when items are re-measured. Monetary assets and liabilities denominated in currencies other than the operation's functional currencies are translated into the functional currency at exchange rates in effect at the balance sheet date. Foreign exchange gains and losses resulting from the settlement of those transactions and from period-end translations are recognized in the consolidated statement of loss. Non-monetary assets and liabilities are translated at historical rates, unless such assets and liabilities are carried at fair value, in which case, they are translated at the exchange rate in effect at the date of the fair value measurement. Changes in fair value attributable to currency fluctuations of non-monetary financial assets and liabilities such as equities held at fair value through profit or loss are recognized in the consolidated statement of loss as part of the fair value gain or loss. Such changes in fair value of non-monetary financial assets, such as equities classified at fair value through other comprehensive income, are included in other comprehensive income or loss.
Financial instruments [Policy Text Block] | e) Financial instruments Financial assets and liabilities are recognized when the Company becomes a party to the contractual provisions of the instrument. Financial assets are derecognized when the rights to receive cash flows from the assets have expired or have been transferred and the Company has transferred substantially all risks and rewards of ownership. Financial assets and liabilities are offset and the net amount is reported in the balance sheet when there is an unconditional and legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis, or realize the asset and settle the liability simultaneously. All financial instruments are required to be measured at fair value on initial recognition. The fair value is based on quoted market prices, unless the financial instruments are not traded in an active market. In this case, the fair value is determined by using valuation techniques like the Black-Scholes option pricing model or other valuation techniques. Measurement after initial recognition depends on the classification of the financial instrument. The Company has classified its financial instruments in the following categories depending on the purpose for which the instruments were acquired and their characteristics. (i) Financial assets Debt instruments Investments in debt instruments are subsequently measured at amortized cost when the asset is held within a business model whose objective is to hold assets in order to collect contractual cash flows and when the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Investments in debt instruments are subsequently measured at fair value when they do not qualify for measurement at amortized cost. Financial instruments subsequently measured at fair value, including derivatives that are assets, are carried at fair value with changes in fair value recorded in net income or loss unless they are held within a business model whose objective is to hold assets in order to collect contractual cash flows or sell the assets and when the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding, in which case unrealized gains and losses are initially recognized in other comprehensive income or loss for subsequent reclassification to net income or loss through amortization of premiums and discounts, impairment or derecognition. Equity instruments Investments in equity instruments are subsequently measured at fair value with changes recorded in net income or loss. Equity instruments that are not held for trading can be irrevocably designated at fair value through other comprehensive income or loss on initial recognition without subsequent reclassification to net income. Cumulative gains and losses are transferred from accumulated other comprehensive income (loss) to retained earnings upon derecognition of the investment. Dividend income on equity instruments measured at fair value through other comprehensive income (loss) is recognized in the statement of loss on the ex-dividend date. (ii) Financial liabilities Financial liabilities are subsequently measured at amortized cost using the effective interest method, except for financial liabilities at fair value through profit or loss. Such liabilities, including derivatives that are liabilities, are subsequently measured at fair value. The Company has classified its financial instruments as follows:
Category | Financial instrument
Financial assets at amortized cost | Bank balances and cash on hand
| Short-term debt securities
| Notes and loans receivable
| Trade receivables
| Interest and dividend income receivable
| Amounts receivable from associates and other receivables
| Reclamation deposits (term deposits)
Financial assets at fair value through profit or loss | Investments in derivatives and convertible debentures
Financial assets at fair value through other comprehensive income or loss | Investments in shares and equity instruments, other than in derivatives
Financial liabilities at amortized cost | Accounts payable and accrued liabilities
| Liability component of convertible debentures
| Borrowings under revolving credit facilities
Derivatives Derivatives, other than warrants held in mining exploration and development companies, are only used for economic hedging purposes and not as speculative investments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently measured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.
Impairment of financial assets [Policy Text Block] | f) Impairment of financial assets At each reporting date, the Company assesses, on a forward-looking basis, the expected credit losses associated with its financial assets carried at amortized cost. The impairment methodology applied depends on whether there has been a significant increase in the credit risk or if a simplified approach has been selected. The Company has two principal types of financial assets subject to the expected credit loss model: Trade receivables; and Investments in debt instruments measured at amortized cost. Amounts receivable The Company applies the simplified approach permitted by IFRS 9 for trade receivables (including amounts receivable from associates and other receivables), which requires lifetime expected credit losses to be recognized from initial recognition of the receivables. Investments in debt instruments To the extent that a debt instrument at amortized cost is considered to have low credit risk, which corresponds to a credit rating within the investment grade category and the credit risk has not increased significantly, the loss allowance is determined on the basis of 12-month expected credit losses. If the credit risk has increased significantly, the lifetime expected credit losses are recognized.
Cash and cash equivalents [Policy Text Block] | g) Cash and cash equivalents Cash includes cash on hand and deposits held with banks. Cash equivalents include other highly liquid short-term investments with original maturities of three months or less or that can be redeemed at any time without penalties.
Refundable tax credits for mining exploration expenses [Policy Text Block] | h) Refundable tax credits for mining exploration expenses The Company is entitled to refundable tax credits on qualified mining exploration and evaluation expenses incurred in the province of Québec. The credits are accounted for against the exploration and evaluation expenses incurred.
Inventories [Policy Text Block] | i) Inventories Inventories are mainly comprised of gold and silver bullions and diamonds in saleable form that have not yet been sold. Inventories are valued at the lower of cost and net realizable value. Cost is determined on a weighted average basis.
Investments in associates [Policy Text Block] | j) Investments in associates Associates are entities over which the Company has significant influence, but not control. The financial results of the Company's investments in its associates are included in the Company's results according to the equity method. Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the Company's share of profits or losses of associates after the date of acquisition. The Company's share of profits or losses is recognized in the consolidated statement of loss and its share of other comprehensive income or loss of associates is included in other comprehensive income or loss. Unrealized gains on transactions between the Company and an associate are eliminated to the extent of the Company's interest in the associate. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Dilution gains and losses arising from changes in interests in investments in associates are recognized in the consolidated statement of loss. The Company assesses at each reporting date whether there is any objective evidence that its investments in associates are impaired. If impaired, the carrying value of the Company's share of the underlying assets of associates is written down to its estimated recoverable amount (being the higher of fair value less costs of disposal and value-in-use) and charged to the consolidated statement of loss.
Royalty, stream and other interests [Policy Text Block] | k) Royalty, stream and other interests Royalty, stream and other interests consist of acquired royalty, stream and other interests in producing, development and exploration and evaluation stage properties. Royalty, stream and other interests are recorded at cost and capitalized as tangible assets. They are subsequently measured at cost less accumulated depletion and depreciation and accumulated impairment losses. The major categories of the Company's interests are producing, development and exploration and evaluation. Producing assets are those that have generated revenue from steady-state operations for the Company. Development assets are interests in projects that are under development, in permitting or feasibility stage and that in management's view, can be reasonably expected to generate steady-state revenue for the Company in the near future. Exploration and evaluation assets represent properties that are not yet in development, permitting or feasibility stage or that are speculative in nature and are expected to require several years to generate revenue, if ever, or are currently not active. Producing and development royalty, stream and other interests are recorded at cost and capitalized in accordance with IAS 16 Property, Plant and Equipment. Producing royalty, stream and other interests are depleted using the units-of-production method over the life of the property to which the interest relates, which is estimated using available estimates of proven and probable mineral reserves specifically associated with the properties and may include a portion of resources expected to be converted into mineral reserves. Management relies on information available to it under contracts with the operators and / or public disclosures for information on proven and probable mineral reserves and resources from the operators of the producing royalty, stream and other interests. On acquisition of a producing or a development royalty, stream and other interest, an allocation of the acquisition cost is made for the exploration potential based on its fair value. The estimated fair value of this acquired exploration potential is recorded as an asset (non-depreciable interest) on the acquisition date. Updated mineral reserve and resource information obtained from the operators of the properties is used to determine the amount to be converted from non-depreciable interest to depreciable interest. Royalty, stream and other interests for exploration and evaluation assets are recorded at cost and capitalized in accordance with IFRS 6 Exploration for and Evaluation of Mineral Resources. Acquisition costs of exploration and evaluation royalty, stream and other interests are capitalized and are not depleted until such time as revenue-generating activities begin. Producing and development royalty, stream and other interests are reviewed for impairment at each reporting date if there is any indication that the carrying amount may not be recoverable. Impairment is assessed at the level of Cash-Generating Units (''CGU'') which, in accordance with IAS 36 Impairment of Assets, are identified as the smallest identifiable group of assets that generates cash inflows, which are largely independent of the cash inflows from other assets. This is usually at the individual royalty, stream and other interest level for each property from which cash inflows are generated. Royalty, stream and other interests for exploration and evaluation assets are assessed for impairment whenever indicators of impairment exist in accordance with IFRS 6. An impairment loss is recognized for the amount by which the asset's carrying value exceeds its recoverable amount, which is the higher of fair value less costs of disposal and value-in-use. An interest that has previously been classified as exploration and evaluation is also assessed for impairment before reclassification to development or producing, and the impairment loss, if any, is recognized in net income.
Property and equipment [Policy Text Block] | l) Property and equipment Property and equipment are stated at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of an asset. Subsequent costs are included in the asset's carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefit associated with the item will flow to the Company and the cost can be measured reliably. The carrying amount of a replaced asset is derecognized when replaced. Depreciation is calculated to amortize the cost of the property and equipment less their residual values over their estimated useful lives using the straight-line method and following periods by major categories: Leasehold improvements Lease term Furniture and office equipment 3-5 years Exploration equipment and facilities 3-20 years Mining plant and equipment (development) 5-20 years Residual values, method of depreciation and useful lives of the assets are reviewed annually and adjusted if appropriate. Gains and losses on disposals of property and equipment are determined by comparing the proceeds with the carrying amount of the asset and are included as part of other gains (losses), net in the consolidated statement of loss.
Exploration and evaluation expenditures [Policy Text Block] | m) Exploration and evaluation expenditures Exploration and evaluation assets are comprised of exploration and evaluation expenditures and mining properties acquisition costs for exploration and evaluation assets. Expenditures incurred on activities that precede exploration and evaluation, being all expenditures incurred prior to securing the legal rights to explore an area, are expensed immediately. Exploration and evaluation assets include rights in mining properties, paid or acquired through a business combination or an acquisition of assets, and costs related to the initial search for mineral deposits with economic potential or to obtain more information about existing mineral deposits. Mining rights are recorded at acquisition cost less accumulated impairment losses. Mining rights and options to acquire undivided interests in mining rights are depreciated only as these properties are put into commercial production. Exploration and evaluation expenditures for each separate area of interest are capitalized and include costs associated with prospecting, sampling, trenching, drilling and other work involved in searching for ore like topographical, geological, geochemical and geophysical studies. They also reflect costs related to establishing the technical and commercial viability of extracting a mineral resource identified through exploration and evaluation or acquired through a business combination or asset acquisition. Exploration and evaluation expenditures include the cost of: (i) establishing the volume and grade of deposits through drilling of core samples, trenching and sampling activities; (ii) determining the optimal methods of extraction and metallurgical and treatment processes; (iii) studies related to surveying, transportation and infrastructure requirements; (iv) permitting activities; and (v) economic evaluations to determine whether development of the mineralized material is commercially justified, including scoping, prefeasibility and final feasibility studies. Exploration and evaluation expenditures include overhead expenses directly attributable to the related activities. Cash flows attributable to capitalized exploration and evaluation costs are classified as investing activities in the consolidated statement of cash flows under the heading exploration and evaluation. Exploration and evaluation assets under a farm-out arrangement (where a farmee incurs certain expenditures in a property to earn an interest in that property) are accounted as follows: (i) the Company uses the carrying value of the interest before the farm-out arrangement as the carrying value for the portion of the interest retained; (ii) the Company credits any cash consideration received against the carrying amount of the portion of the interest retained, with an excess included as a gain in profit or loss; (iii) in the situation where a royalty interest is retained by the Company as a result of an interest earned by the farmee, the Company records the royalty interest received at an amount corresponding to the carrying value of the exploration and evaluation property at the time of the transfer in ownership; and (iv) the Company does not record exploration expenditures made by the farmee on the property.
Goodwill [Policy Text Block] | n) Goodwill Goodwill is recognized in a business combination if the cost of the acquisition exceeds the fair value of the identifiable net assets acquired. Goodwill is then allocated to the CGU or group of CGUs that are expected to benefit from the synergies of the combination. The Company performs goodwill impairment tests on an annual basis as at December 31 of each year. In addition, the Company assesses for indicators of impairment at each reporting date and, if an indicator of impairment is identified, goodwill is tested for impairment at that time. If the carrying value of the CGU or group of CGUs to which goodwill is assigned exceeds its recoverable amount, an impairment loss is recognized. Goodwill impairment losses are not reversed. The recoverable amount of a CGU or group of CGUs is measured as the higher of value-in-use and fair value less costs of disposal.
Provision for environmental rehabilitation [Policy text Block] | o) Provision for environmental rehabilitation Provision for environmental rehabilitation, restructuring costs and legal claims, where applicable, is recognized when: (i) The Company has a present legal or constructive obligation as a result of past events. (ii) It is probable that an outflow of resources will be required to settle the obligation. (iii) The amount can be reliably estimated. The provision is measured at management's best estimate of the expenditure required to settle the obligation at the end of the reporting period, and are discounted to present value where the effect is material. The increase in the provision due to passage of time is recognized as finance costs. Changes in assumptions or estimates are reflected in the period in which they occur. Provision for environmental rehabilitation represents the legal and constructive obligations associated with the eventual closure of the Company's property, plant and equipment. These obligations consist of costs associated with reclamation and monitoring of activities and the removal of tangible assets. The discount rate used is based on a pretax rate that reflects current market assessments of the time value of money and the risks specific to the obligation, excluding the risks for which future cash flow estimates have already been adjusted. Reclamation deposits Reclamation deposits are term deposits held on behalf of the Government of the Province of British Columbia as collateral for possible rehabilitation activities on the Company's mineral properties in connection with permits required for exploration activities. Reclamation deposits are released once the property is restored to satisfactory condition, or as released under the surety bond agreement. As they are restricted from general use, they are included under non-current other assets on the consolidated balance sheets.
Current and deferred income tax [Policy Text Block] | p) Current and deferred income tax The tax expense for the period comprises current and deferred tax. Tax is recognized in the consolidated statement of loss, except to the extent that it relates to items recognized in other comprehensive income or loss or directly in equity. In this case, the tax is also recognized in other comprehensive income or loss or directly in equity, respectively. Current income taxes The current income tax charge is the expected tax payable on the taxable income for the year, using the tax laws enacted or substantively enacted at the balance sheet date in the jurisdictions where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred income taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. However, the deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax assets and liabilities are measured using enacted or substantively enacted tax rates (and laws) that apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, 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. Deferred income tax assets and liabilities are presented as non-current and are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.
Convertible debentures [Policy Text Block] | q) Convertible debentures The liability and equity components of convertible debentures are presented separately on the consolidated balance sheet starting from initial recognition. The liability component is recognized initially at the fair value, by discounting the stream of future payments of interest and principal at the prevailing market rate for a similar liability of comparable credit status and providing substantially the same cash flows that do not have an associated conversion option. Subsequent to initial recognition, the liability component is measured at amortized cost using the effective interest method; the liability component is increased by accretion of the discounted amounts to reach the nominal value of the debentures at maturity. The carrying amount of the equity component is calculated by deducting the carrying amount of the financial liability from the amount of the debentures and is presented in shareholders' equity as equity component of convertible debenture. The equity component is not re-measured subsequent to initial recognition except on conversion or expiry. A deferred tax liability is recognized with respect to any temporary difference that arises from the initial recognition of the equity component separately from the liability component. The deferred tax is charged directly to the carrying amount of the equity component. Subsequent changes in the deferred tax liability are recognized through the consolidated statement of loss. Transaction costs are distributed between liability and equity on a pro-rata basis of their carrying amounts.
Share capital [Policy Text Block] | r) Share capital Common shares are classified as equity. Incremental costs directly attributable to the issuance of shares are recognized as a deduction from the proceeds in equity in the period where the transaction occurs.
Warrants [Policy Text Block] | s) Warrants Warrants are classified as equity. Incremental costs directly attributable to the issuance of warrants are recognized as a deduction from the proceeds in equity in the period where the transaction occurs.
Revenue recognition [Policy Text Block] | t) Revenue recognition Revenue comprises revenues from the sale of commodities received and revenues directly earned from royalty, stream and other interests. For royalty and stream agreements paid in-kind and for offtake agreements, the Company's performance obligations relate primarily to the delivery of gold, silver or other products to the customers. Revenue is recognized when control is transferred to the customers, which is achieved when a product is delivered, the customer has full discretion over the product and there is no unfulfilled obligation that could affect the customer's acceptance of the product. Control over the refined gold, silver and other products is transferred to the customers when the relevant product received (or purchased) from the operator is physically delivered and sold by the Company (or its agent) to the third party customers. For royalty and stream agreements paid in cash, revenue recognition will depend on the related agreement. Revenue is measured at fair value of the consideration received or receivable when management can reliably estimate the amount, pursuant to the terms of the royalty, stream and other interest agreements. In some instances, the Company will not have access to sufficient information to make a reasonable estimate of revenue and, accordingly, revenue recognition is deferred until management can make a reasonable estimate. Differences between estimates and actual amounts are adjusted and recorded in the period that the actual amounts are known.
Leases [Policy Text Block] | u) Leases The Company is committed to long-term lease agreements, mainly for office space. Until December 31 2018, payments made under operating lease agreements were recognized in profit or loss on a straight-line basis over the term of the lease. Operating leases were leases in which a significant portion of the risks and rewards of ownership was retained by the lessor. From January 1, 2019, leases are recognized as a right-of-use asset (presented under non-current other assets on the consolidated balance sheet) and a corresponding liability at the date at which the leased asset is available for use by the Company. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The right-of-use asset is depreciated over the shorter of the asset's useful life and the lease term on a straight-line basis. Assets and liabilities arising from a lease are initially measured on a present value basis. The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, the Company's incremental borrowing rate is used, being the rate that the Company would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions. Payments associated with short-term leases (12 months or less) and leases of low-value assets are recognized on a straight-line basis as an expense in profit or loss.
Share-based compensation [Policy Text Block] | v) Share-based compensation Share option plan The Company offers a share option plan for its directors, officers, employees and consultants. Each tranche in an award is considered a separate award with its own vesting period and grant date fair value. Fair value of each tranche is measured at the date of grant using the Black-Scholes option pricing model. Compensation expense is recognized over the tranche's vesting period by increasing contributed surplus based on the number of awards expected to vest. The number of awards expected to vest is reviewed at least annually, with any impact being recognized immediately. Any consideration paid on exercise of share options is credited to share capital. The contributed surplus resulting from share-based compensation is transferred to share capital when the options are exercised. Deferred and restricted share units Deferred share units ("DSU") may be granted to directors and restricted share units ("RSU") may be granted to employees, directors and officers as part of their long-term compensation package, entitling them to receive a payment in the form of common shares, cash (based on the Company's share price at the relevant time) or a combination of common shares and cash, at the sole discretion of the Company. The fair value of the DSU and RSU to be settled in common shares is measured on the grant date and is recognized over the vesting period under contributed surplus with a corresponding charge to share-based compensation. A liability for the DSU and RSU to be settled in cash is measured at fair value on the grant date and is subsequently adjusted at each balance sheet date for changes in fair value. The liability is recognized over the vesting period with a corresponding charge to share-based compensation.
Earnings per share [Policy Text Block] | w) Earnings per share The calculation of earnings per share ("EPS") is based on the weighted average number of shares outstanding for each period. The basic EPS is calculated by dividing the profit or loss attributable to the equity owners of Osisko by the weighted average number of common shares outstanding during the period. The computation of diluted EPS assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on the income per share. The treasury stock method is used to determine the dilutive effect of the warrants, share options, DSU and RSU and the if-converted method is used for convertible debentures. When the Company reports a loss, the diluted net loss per common share is equal to the basic net loss per common share due to the anti-dilutive effect of the outstanding warrants, share options, DSU and RSU and convertible debentures.
Segment reporting [Policy Text Block] | x) Segment reporting The operating segments are reported in a manner consistent with the internal reporting provided to the Chief Executive Officer ("CEO") who fulfills the role of the chief operating decision-maker. The CEO is responsible for allocating resources and assessing performance of the Company's operating segments. Following the acquisition of Barkerville (Note 7) in November 2019, the Company manages its business under two operating segments: (i) acquiring and managing precious metal and other royalties, streams and similar interests, and (ii) the exploration, evaluation and development of mining projects. Prior to the acquisition of Barkerville, the Company had only one operating segment, which was acquiring and managing precious metal and other royalties, streams and similar interests. The comparative figures have been restated to conform to the current segments.
