21. Financial instruments

The Company’s financial instruments consist of cash and cash equivalents, trade receivables, lease receivable, restricted cash, accounts payable and accrued liabilities, notes payable, and warrant liabilities. The Company is exposed to risks related to changes in interest rates and management of cash and cash equivalents and short-term investments.

Credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, and restricted cash. These assets include Canadian dollar and U.S. dollar denominated certificates of deposit, money market accounts, and demand deposits. These instruments are maintained at financial institutions in Canada and the U.S. Of the amount held on deposit, approximately $0.6 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation, or the U.S. Federal Deposit Insurance Corporation, leaving approximately $68.0 million at risk on December 31, 2023, should the financial institutions with which these amounts are invested be rendered insolvent. The Company does not consider any of its financial assets to be impaired as of December 31, 2023.

Currency risk

As of December 31, 2023, we maintained a balance of approximately $2.8 million Canadian dollars. The funds will be used to pay Canadian dollar expenses and are considered to be a low currency risk to the Company. A hypothetical 10% weakening in the exchange rate of the Canadian dollar to the U.S. dollar as of December 31, 2023 would not have a material effect on our results of operations, financial position, or cash flows.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. As of December 31, 2023, the Company’s financial liabilities consisted of accounts payable and accrued liabilities of $2.4 million, the current portion of lease liability of $0.2 million, and the current portion of notes payable of $5.7 million. As of December 31, 2023, we had $59.7 million of cash and cash equivalents.

Interest rate risk

The Company has completed a sensitivity analysis to estimate the impact that a change in interest rates would have on the net loss of the Company. This sensitivity analysis shows that a change of +/- 100 basis points in interest rate would have a negligible effect on the years ended December 31, 2023, 2022, and 2021. The financial position of the Company may vary at the time that a change in interest rates occurs causing the impact on the Company’s results to vary.
