Commitments and Contingencies Disclosure [Text Block] | 18. Contingencies: From time to time, the Company has legal claims and lawsuits in connection with its ordinary business operations. The Company vigorously defends such claims. While the final outcome with respect to any actions or claims outstanding or pending as of June 30, 2021 cannot be predicted with certainty, management does not believe that the resolution of these claims, individually or in the aggregate, will have a material adverse effect on the Company's financial position.
