Dear Sirs/Mesdames:

Re: Mind Medicine (MindMed) Inc.- Registration Statement on Form S-3

We have acted as Canadian counsel to Mind Medicine (MindMed) Inc., a British Columbia company (the “Company”), in connection with the offer and sale by the Company of 16,666,667 common shares, without par value, of the Company (the “Common Shares”), pursuant to a Registration Statement on Form S-3 (file number 333-264648) (the “Prior Registration Statement”), filed by the Company on May 4, 2022 under the U.S. Securities Act of 1933, as amended (the “Securities Act”) and declared effective by the United States Securities and Exchange Commission (“SEC”) on May 16, 2022 and the base prospectus included in the Registration Statement (the “Base Prospectus”) and the related Registration Statement on Form S-3 filed by the Company on March 7, 2024 pursuant to Rule 462(b) under the Securities Act (the “Rule 462(b) Registration Statement” and, together with the Prior Registration Statement, the “Registration Statements”) and the final prospectus supplement related to the Common Shares dated March 7, 2024 (the “Prospectus Supplement”, and, together with the Base Prospectus, the “Prospectus”).

The offer and sale of the Common Shares is being made pursuant to an underwriting agreement dated March 7, 2024 among the Company and Leerink Partners LLC and Cantor Fitzgerald & Co., as representatives of the underwriters named therein (such agreement, the “Underwriting Agreement”).

We have examined copies of the Underwriting Agreement, the Prospectus and the Registration Statements and all such corporate and public records, statutes and regulations and have made such investigations and have reviewed such other documents as we have deemed relevant and necessary and have considered such questions of law as we have considered relevant and necessary in order to give the opinions hereinafter set forth. As to various questions of fact material to such opinions which were not independently established, we have relied upon a certificate of an officer of the Company.
