Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share

The following table lists the equity securities that were excluded from the computation of diluted earnings per share. The securities were excluded as the exercise price related to the particular security exceeded the average market price of the Company's common shares of CAD $10.01 for the year ended December 31, 2021 (2020 - CAD $10.87), or the inclusion of the equity securities had an anti-dilutive effect on net loss. For the periods in which the Company records a net loss, diluted loss per share is calculated using the basic weighted average number of shares outstanding, as using the diluted weighted average number of shares outstanding in the calculation would be anti-dilutive.
