Ladies and Gentlemen:

We have acted as counsel to Loop Industries, Inc., a Nevada corporation (the “Corporation”), in connection with the Corporation’s Registration Statement on Form S-3 (File No. 333-226789), as filed with the United States Securities and Exchange Commission (the “Commission”) on August 10, 2018, and as further amended or supplemented from time to time to the date hereof (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”).  The Registration Statement covers the offer and sale pursuant to that certain Underwriting Agreement dated as of September 21, 2020, (the “Underwriting Agreement”) between the Corporation and Roth Capital Partners, LLC (the “Underwriter”), of 1,880,000 shares (the “Firm Shares”) of the Corporation’s common stock, par value $0.0001 per share (the “Common Stock”), and 282,000 shares (the “Option Shares” and, together with the Firm Shares, the “Shares”) of Common Stock permitted to be purchased by the Underwriter pursuant to the 30-day option to purchase additional shares, if any, under the Underwriting Agreement.

We have reviewed the following documents: (i) the Articles of Incorporation of the Corporation, as filed with the Nevada Secretary of State on March 11, 2010, as amended (the “Articles”); (ii) the Amended and Restated By-laws of the Corporation, effective as of April 4, 2018; (iii) the resolutions adopted by the Corporation’s board of directors and the pricing committee of the board of directors authorizing the execution and delivery of the Underwriting Agreement, the issuance and sale of the Shares pursuant to the Underwriting Agreement, and matters related thereto; (iv) the Registration Statement and the exhibits thereto; and (v) the Underwriting Agreement. We have also reviewed such corporate records and other agreements, documents and instruments, and such certificates or comparable documents of public officials and officers and representatives of the Corporation and have made such inquiries of such officers and representatives and have considered such matters of law as we have deemed appropriate as the basis for the opinions hereinafter set forth.

In delivering this opinion letter, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as certified, photostatic or conformed copies, the authenticity of originals of all such latter documents, and the accuracy and completeness of all records, information and statements submitted to us by officers and representatives of the Corporation. In making our examination of documents executed by parties other than the Corporation, we have assumed that such parties had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization of all requisite action, corporate or other, and execution and delivery by such parties of such documents, and the validity and binding effect thereof with respect to all parties.

The opinions expressed below are based on the assumptions that: (i) the Registration Statement and any amendments or supplements thereto (including any post-effective amendments) have been filed by the Corporation with the Commission and will be effective at the time that any of the Shares are issued, and that persons acquiring the Shares will do so strictly in accordance with the terms of the Underwriting Agreement and will receive a prospectus containing all of the information required by Part I of the Registration Statement before acquiring such Shares; (ii) the Shares will continue to be duly and validly authorized on the dates that the Shares are issued, and, upon the issuance of any of the Shares, the total number of shares of Common Stock of the Corporation issued and outstanding, after giving effect to such issuance of such Shares, will not exceed the total number of shares of Common Stock that the Corporation is then authorized to issue under the Articles, as may be further amended; (iii) the Underwriting Agreement will not violate or constitute a default or breach under (a) any agreement or instrument to which the Corporation or its properties is subject, (b) any law, rule or regulation to which the Corporation is subject, (c) any judicial or regulatory order or decree of any governmental authority, or (d) any consent, approval, license, authorization or validation of or filing, recording or registration of any governmental authority; and (iv) the Shares will be issued and sold in compliance with the Securities Act and the securities or “Blue Sky” laws of various states.

On the basis of the foregoing, and subject to the qualifications, assumptions, and limitations set forth herein, we are of the opinion that the Shares issuable in connection with the Underwriting Agreement have been duly authorized for issuance and, when the Shares are issued and delivered against receipt of payment therefore in accordance with the Underwriting Agreement, the Shares will be duly authorized, validly issued, fully paid and nonassessable.
