assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to the original of all documents submitted to us as certified, photocopied, electronic or facsimile copies;

assumed that the Terms Agreement and the Fiscal Agency Agreement have been duly authorized, executed and delivered by or on behalf of each of the parties thereto other than Québec;

assumed that a draft of the Prospectus Supplement containing, inter alia, a description of the terms of the Notes was delivered to the Underwriters, at or prior to the signing of the Terms Agreement;

relied, as to matters of United States law and procedure, upon the opinion of Sullivan & Cromwell LLP, the Underwriters’ United States counsel, delivered to you on the date hereof pursuant to Section 5(f) of the Underwriting Agreement Standard Provisions;

assumed that, insofar as any obligation fails to be performed in any jurisdiction outside Québec, its performance would not be illegal or ineffective by virtue of the laws of that jurisdiction; and

relied on the certificate of an authorized official of the Ministère des Finances of Québec relating to the debt securities of Québec outstanding as at the date hereof and to certain questions of fact.

the creation, execution and sale of the Notes have been duly authorized by Québec and the Global Notes have been duly executed by Québec in accordance with the laws of Québec in effect on the date hereof, the Ministerial Order and the Order in Council. When the Global Notes are duly authenticated in accordance with the provisions of the Fiscal Agency Agreement and delivered to and paid for by the Underwriters pursuant to the Terms Agreement, they will constitute valid and legally binding, unsecured and unconditional general obligations of Québec, for the payment and performance of which the full faith and credit of Québec will be pledged; and the Global Notes will be enforceable against Québec in accordance with their terms, subject to the qualifications set forth in paragraph E) herein, and subject furthermore to the provisions of Book Ten, Title Four of the Civil Code of Québec whereby, in recognizing and enforcing a decision rendered by a court outside Québec for a sum of money expressed in foreign currency, a Québec court will convert that sum of money in Canadian currency at the rate of exchange prevailing on the day such decision becomes enforceable at the place where it was rendered and whereby, in the cases listed below, a decision rendered by a court outside Québec would not be recognized and, where applicable, declared enforceable by a Québec court:

the court rendering the decision had no jurisdiction under the provisions of the Civil Code of Québec;

the decision is not final or enforceable at the place where it was rendered, is in contravention of fundamental principles of procedure, or is manifestly inconsistent with public order as understood in international relations;

a decision on the same matter either (i) is pending before or has been rendered by a Québec court or (ii) has been rendered by a foreign tribunal and is recognizable in Québec;

the decision enforces obligations resulting from taxation laws of a foreign country which does not itself recognize and enforce the obligations resulting from the taxation laws of Québec; or

the decision is rendered by default and the act of procedure initiating the proceedings was not duly served on the defaulting party;

the Notes rank equally among themselves and with the other debt securities issued by Québec and outstanding on the date hereof and all funds required to make payments in respect of the Notes will be taken out of the Consolidated Revenue Fund of Québec;

the Terms Agreement and the Fiscal Agency Agreement have been duly authorized, executed and delivered by Québec in accordance with the Order in Council and the Ministerial Order and each constitutes a legal, valid and binding obligation of Québec, enforceable in accordance with its terms;

all necessary actions have been duly taken by or on behalf of Québec and all necessary authorizations and approvals under the laws of Québec have been duly obtained, for the authorization, execution and delivery by Québec of the Terms Agreement, the Fiscal Agency Agreement and the Notes and for the issuance and sale of the Notes pursuant to the Terms Agreement and the Fiscal Agency Agreement, and there are no laws of Canada applicable to any such authorization, execution, delivery, issuance or sale and no authorizations or approvals under the laws of Canada are necessary therefor; and

Québec does not enjoy, under the laws of Québec and the laws of Canada applicable therein, a right of immunity from suit, on the ground of sovereignty or otherwise, in respect of its obligations under the Fiscal Agency Agreement, the Terms Agreement and the Notes, subject to the following qualifications:

the provisions of the Code of Civil Procedure of Québec which bar extraordinary recourses (quo warranto, mandamus and evocation) and provisional remedies (injunction, seizure of assets before judgment and judicial sequestration) against the Gouvernement du Québec; and

the general immunity of the State from compensation, set-off, acquisitive prescription, attachment and execution on a judgment.

as of May 27, 2026, the Registration Statement contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

as of 1:15 p.m. (New York time) on May 27, 2026, the Pricing Disclosure Package contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

as of May 27, 2026, the Prospectus, as supplemented by the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

the foregoing opinions are based upon legislation in effect as of the date hereof and are limited to the laws of Québec and the laws of Canada applicable therein;

we do not express any opinion or belief as to the financial statements or other financial or statistical data contained in the Registration Statement, the Prospectus, the Pricing Disclosure Package and the Prospectus Supplement and we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained therein except for those made in the Prospectus under the captions “Plan of Distribution” and “Description of the Securities” and in the Prospectus Supplement under the captions “Description of Notes” and “Underwriting” insofar as they relate to provisions of documents therein described and to the Notes, or as to Canadian taxes, as described in the immediately preceding paragraph of this opinion;

insofar as the foregoing opinions relate to the due execution of the Notes, we have examined only the specimen of the Global Notes referred to in paragraph (h) above, and have assumed (without independently verifying the assumptions) that such Global Notes conform to such specimen and that the certificate of authentication on such Global Notes has been manually signed on behalf of the Fiscal Agent by a person duly authorized for such purpose;

the foregoing opinions are subject to bankruptcy, insolvency and other laws affecting the enforcement of creditors’ rights generally, to general equitable principles, including certain equitable principles contained in the Civil Code of Québec, and to the fact that certain recourses, such as specific performance or injunction proceedings, are ordered in the discretion of a court of competent jurisdiction;

the Civil Code of Québec provides that notwithstanding the designation in a contract of the laws of Québec as being the governing laws, if the laws of Québec invalidate the designation, the courts apply the laws of the country with which the act is most closely connected (within the meaning of the Civil Code of Québec), in view of its nature and the attendant circumstances;

rights to indemnity and contribution may be limited by applicable law; and

under the provisions of the Currency Act (Canada), the courts are precluded from rendering any monetary judgment in any currency other than the lawful currency of Canada.
