The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash, accounts payable and accrued liabilities, and notes payable. 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 $0.5 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation, or the U.S. Federal Deposit Insurance Corporation, leaving approximately $11.6 million at risk on December 31, 2020 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, 2020.

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, 2020, the Company’s financial liabilities consisted of accounts payable and accrued liabilities of $2.3 million, and the current portion of notes payable of $0.5 million.

On May 15, 2020, we filed a universal shelf registration statement on Form S-3 with the SEC in order that we may offer and sell, from time to time, in one or more offerings, at prices and terms to be determined, up to $100 million of our Common Shares, warrants to purchase our Common Shares, our senior and subordinated debt securities, and rights to purchase our Common Shares and/or senior and subordinated debt securities. The registration statement became effective May 27, 2020 for a three-year period.  In August 2020, we utilized the registration statement for a $4.68 million registered direct offering (see note 13) and in February 2021, we utilized the registration statement for a $15.2 million underwritten public offering (see note 22).

On May 29, 2020, we entered into an At Market Issuance Sales Agreement (the “Sales Agreement”) with B. Riley Securities, Inc. (formerly, B. Riley FBR, Inc.), under which we may, from time to time, issue and sell common shares at market prices on the NYSE American LLC through the Agent for aggregate sales proceeds of up to $10,000,000. The Sales Agreement replaces the prior At Market Issuance Sales Agreement entered by the Company on May 27, 2016, as amended. In 2020 Q4, we utilized the Sales Agreement and received gross proceeds of $0.1 million.

Sensitivity analysis

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, 2020, 2019, or 2018. 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.
