Corporate Information And Statement Of IFRS Compliance [Abstract]
BASIS OF PREPARATION	BASIS OF PREPARATION: (a) Statement of compliance: These 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 for the fiscal year ended January 2, 2022 were authorized for issuance by the Board of Directors of the Company on February 22, 2022. (b) Basis of measurement: These consolidated financial statements have been prepared on the historical cost basis except for the following items in the consolidated statements of financial position: •Derivative financial instruments which are measured at fair value; •Employee benefit obligations related to defined benefit plans which are measured at the present value of the defined benefit obligations, net of advance payments made to employees thereon; •Liabilities for cash-settled share-based payment arrangements which are measured at fair value, and equity-classified share-based payment arrangements which are measured at fair value at grant date pursuant to IFRS 2, Share-based payment; •Discontinued, damaged, and excess finished inventories which are carried at the net realizable value; •Provisions for decommissioning, site restoration costs, and onerous contracts which are measured at the present value of the expenditures expected to be required to settle the obligation; and •Identifiable assets acquired and liabilities assumed in connection with a business combination which are initially measured at fair value. These consolidated financial statements are presented in U.S. dollars, which is the Company's functional currency. 2. BASIS OF PREPARATION (continued): (c) Initial application of new or amended accounting standards: During the year ended January 2, 2022, the Company adopted the following new or amended accounting standards: Interest Rate Benchmark Reform On August 27 2020, the IASB published "Interest Rate Benchmark Reform - Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16)" to address issues relating to the modification of financial assets, financial liabilities and lease liabilities, specific hedge accounting requirements, and disclosure requirements when an existing interest rate benchmark is actually replaced. The amendment introduces a practical expedient for modifications required by the reform (modifications required as a direct consequence of the IBOR reform and made on an economically equivalent basis). These modifications are accounted for by updating the effective interest rate. All other modifications are accounted for using the current IFRS requirements. A similar practical expedient is available for lessee accounting under IFRS 16. Under the amendments, hedge accounting is not discontinued solely because of the IBOR reform. Hedging relationships (and related documentation) must be amended to reflect modifications to the hedged item, hedging instrument, and hedged risk. Amended hedging relationships should meet all qualifying criteria to apply hedge accounting, including effectiveness requirements. The amendments are effective for annual reporting periods beginning on or after January 1, 2021 and are to be applied retrospectively. The Company has begun discussions with its lenders to amend existing debt agreements to include LIBOR fallback provisions. To date, the adoption has not had an impact on the Company's consolidated financial statements as LIBOR is still being used as the interest rate benchmark in its existing debt agreements. In addition, the Company and its counterparties under interest rate swap agreements are expected to negotiate the substitution of reference rates in such agreements. It is too early to determine if any upcoming potential modifications will meet the requirements for the application of the practical expedient. During the year ended January 3, 2021, the Company adopted the following new accounting standards: Amendments to IFRS 3, Business combinations In October 2018, the IASB issued amendments to IFRS 3, Business combinations. The amendments clarify the definition of a business, with the objective of assisting entities in determining whether a transaction should be accounted for as a business combination or as an asset acquisition. The amendments are effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after January 1, 2020 and apply prospectively. Given the prospective application of the amendment, its adoption did not have an impact on the Company’s consolidated financial statements. Interest Rate Benchmark Reform - Phase 1 On September 26, 2019, the IASB published "Interest Rate Benchmark Reform - Phase 1 (Amendments to IFRS 9, IAS 39 and IFRS 7)" as a first reaction to the potential effects the IBOR reform could have on financial reporting. Interbank offered rates ("IBORs") are interest reference rates, such as LIBOR, EURIBOR and TIBOR, that represent the cost of obtaining unsecured funding, in a particular combination of currency and maturity, and in a particular interbank term lending market. The amendments from Phase 1 modified specific hedge accounting requirements so that entities would apply those hedge accounting requirements assuming that the interest rate benchmark on which the hedged cash flows and cash flows from the hedging instrument are based will not be altered as a result of interest rate benchmark reform. The Company had floating rate debt with a variable rate of interest linked to U.S. LIBOR as a benchmark for establishing the rate in the amount of $400 million outstanding as at January 2, 2022, a portion of which was hedged with $250 million of floating-to-fixed interest rate swaps that are designated as cash flow hedges as described in note 15(b). The Company early adopted the Phase 1 amendments effective September 30, 2019 (first day of the fourth quarter of fiscal 2019). The amounts included in other comprehensive income in relation to floating-to-fixed interest rate swaps that are designated as cash flow hedges and that are mostly affected by the IBOR reform were not significant at the date of adoption.
