We have assumed that all Common Shares issued under the Awards will be issued for consideration in money or in property or past services that is not less in value than the fair April 4, 2022

Our opinion is given as of the date hereof and we do not in any event undertake to advise you of any facts or circumstances occurring or coming to our attention subsequent to the date hereof. We are qualified to practice law only in the Province of Ontario.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the references to our firm name therein. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.
