Ladies and Gentlemen:

We have acted as United States counsel to Devonian Health Group Inc., a corporation incorporated under the laws of Canada (the “Company”), in connection with a Registration Statement on Form F-1 (the “Registration Statement”) filed by the Company with the United States Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933, as amended (the “Securities Act”), relating to the offer and sale by the Company of an aggregate of up to US$28,244,000 of: (i) common units (the “Common Units”), with each Common Unit consisting of one common share, no par value, of the Company (collectively, the “Common Shares”) and one warrant to purchase one Common Share (collectively, the “Warrants”), and/or (ii) pre-funded units (collectively, the "Pre-funded Units"), with each Pre-funded Unit consisting of one pre-funded warrant to purchase one Common Share (collectively, the "Pre-funded Warrants") and one Warrant (the “Offering”), including Common Shares (the “Over-Allotment Shares”) and/or Pre-funded Warrants (the "Over-Allotment Pre-funded Warrants"), , and/or Warrants (the "Over-Allotment Warrants") representing up to 15% of the Common Shares and/or Pre-Funded Warrants sold in the Offering, pursuant to the over-allotment option granted to ThinkEquity LLC, as Representative (the “Representative”) of the several underwriters (the “Underwriters”) named in Schedule I to the Underwriting Agreement (as defined below). In addition, the Company has agreed to issue to the Underwriter, as compensation for its services pursuant to an underwriting agreement to be entered into by and between the Company and the Underwriter (the “Underwriting Agreement”), substantially in the form filed as Exhibit 1.1 to the Registration Statement, warrants, representing up to 5% of the aggregate number of Common Shares sold in the Offering (the “Underwriter Warrants”), with each warrant exercisable to purchase one Common Share.

The Warrants and any Over-Allotment Warrants will be governed by the terms of the Form of Warrant and a warrant agent agreement (the “Warrant Agent Agreement”) by and between the Company and Continental Stock Transfer & Trust, as warrant agent.

This opinion letter is furnished to you for filing with the Commission pursuant to Item 601 of Regulation S-K, promulgated under the Securities Act.
