Income Tax Disclosure [Abstract]

11.	Income taxes:

Income tax recovery for the three and six months ended June 30, 2021 and 2020 arose from the operations of Xenon Pharmaceuticals USA Inc., the Company’s wholly-owned subsidiary in the United States. Deferred income tax assets recorded on the consolidated balance sheets as of June 30, 2021 and December 31, 2020 resulted from the temporary differences between the amounts of assets and liabilities recognized for financial statement and income tax purposes related to the operations of Xenon Pharmaceuticals USA Inc. The realization of deferred income tax assets is dependent upon the generation of sufficient taxable income during future periods in which the temporary differences are expected to reverse.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
