Bank of Montreal,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100 King Street West,

1 First Canadian Place,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Toronto, Ontario,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Canada M5X 1A1.

Ladies and Gentlemen:

We are acting as counsel to Bank of Montreal, a Canadian chartered bank (the "Bank"), in connection with the issuance and delivery of US$750,000,000 principal amount of the Bank's 4.547% Fixed/Floating Rate Senior Notes due 2029, US$750,000,000 principal amount of the Bank's 4.879% Fixed/Floating Rate Senior Notes due 2032 and US$1,250,000,000 principal amount of the Bank's 5.298% Fixed/Floating Rate Senior Notes due 2037 (collectively, the "Notes"). The Bank filed with the Securities and Exchange Commission, on March 3, 2025, a registration statement on Form F-3 (File No. 333-285508), as subsequently amended on March 25, 2025 (the "Registration Statement"), under the Securities Act of 1933 (the "Act") relating to, among other things, the proposed offer and sale of up to US$75,000,000,000 aggregate amount of securities of the Bank, including the Notes. The Notes are being issued pursuant to the Indenture, dated as of January 25, 2010, as supplemented by the First Supplemental Indenture thereto, dated as of September 23, 2018, between the Bank and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (the "Trustee"), and the Fifth Supplemental Indenture thereto, dated as of August 14, 2025 (collectively, the "Indenture"), among the Bank, the Trustee and The Bank of New York Mellon.

We have examined such corporate records, certificates and other documents, and such questions of United States federal and New York state law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that the Notes constitute valid and legally binding obligations of the Bank, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles; *provided*, *however*, that we express no opinion with respect to Section 301(b) and Section 1601(a) of the Indenture (and the corresponding provisions in the Notes), which are governed by the laws of the Province of Ontario and the Federal laws of Canada applicable therein.

------

The foregoing opinion is limited to the federal laws of the United States and the laws of the State of New York, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

In rendering the foregoing opinion, we are not passing upon, and assume no responsibility for, any disclosure in the Registration Statement or any related prospectus or other offering material regarding the Bank or the Notes or their offering and sale.

We have relied as to certain factual matters on information obtained from public officials, officers of the Bank and other sources believed by us to be responsible, and we have assumed, without independent verification, that the Bank is duly organized, validly existing and in good standing under the laws of Canada, that all corporate action by the Bank related to the Notes was duly authorized as a matter of Canadian law, that the Indenture has been duly authorized, executed and delivered by the Bank insofar as the laws of Canada are concerned, that the Indenture has been duly authorized, executed and delivered by the Trustee, that the Notes conform to the specimens thereof examined by us, that the Notes have been duly authenticated by one of the Trustee's authorized officers, that the Notes have been delivered against payment as contemplated in the Registration Statement and that the signatures on all documents examined by us are genuine.

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 6-K to be incorporated by reference in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.

Capitalized terms used herein and not otherwise defined herein have the meanings ascribed to such terms in the Terms Agreement.

We have examined copies, certified or otherwise authenticated to our satisfaction, of the following:

(i) the Distribution Agreement;

(ii) the Terms Agreement;

------

![LOGO](g12742g13l28.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(iii) the Indenture;

(iv) the registration statement of the Bank on Form F-3 dated March 3, 2025
and Amendment No. 1 thereto dated March 25, 2025 (collectively, the "**Registration Statement** "); and

(v) the prospectus of the Bank dated March 25, 2025 included in the Registration Statement (the "**Basic Prospectus**") as supplemented by the prospectus supplement dated March 25, 2025 specifically relating to the Bank's Senior Medium-Term Notes, Series J and Senior Medium-Term Notes, Series K (the "**Prospectus Supplement**") and the pricing supplement dated May 28, 2026 (the "**Pricing Supplement** ", and together with the Basic Prospectus and the Prospectus Supplement, the "**Prospectus** ").

We understand that the Registration Statement and the Prospectus were filed with the United States Securities and Exchange Commission in connection with the Notes.

For the purposes of our opinion below, we have examined such statutes, public and corporate records, certificates and other documents, and considered such questions of law, as we have considered relevant and necessary as a basis for the opinions hereinafter set forth. In such examination we have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as certified, conformed, photostatic or electronic copies. For the purposes of the opinions expressed herein, we have, without independent investigation or verification, assumed that each of the Distribution Agreement, the Terms Agreement and the Indenture has been duly authorized, executed and delivered by, and constitutes or will constitute, as the case may be, a legal, valid and binding obligation of, each party thereto other than the Bank.

In giving this opinion, we express no opinion as to any laws other than the laws, at the date hereof, of the Province of Ontario and the federal laws of Canada applicable therein.

With respect to the continuing existence of the Bank as a Schedule I bank under the *Bank Act* (Canada) referred to in paragraph 1 below, we have relied, without independent investigation or verification, exclusively upon a Certificate of Confirmation dated June 1, 2026 issued by the Office of the Superintendent of Financial Institutions, which certificate we assume is accurate as of the date hereof.

Based and relying upon the foregoing and subject to the qualifications set forth herein, we are of the opinion that:

1. The Bank validly exists as a Schedule I bank under the *Bank Act* (Canada) and has the corporate power to own,
lease and operate its properties, to conduct its business as described in the Prospectus, to create, issue and sell the Notes and to execute, deliver and perform its obligations under the Indenture.

------

![LOGO](g12742g13l28.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

2. The creation, issuance, sale and delivery of the Notes have been duly authorized by the Bank and the Notes have been,
to the extent issuance, execution and delivery are matters governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, duly issued, executed and delivered by the Bank.

3. The Indenture has been duly authorized, executed and, to the extent delivery is a matter governed by the laws of the
Province of Ontario and the federal laws of Canada applicable therein, delivered by the Bank and, with respect to the provisions thereof governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, constitutes a
legal, valid and binding obligation of the Bank enforceable in accordance with its terms.

4. The execution and delivery by the Bank of, and the performance by the Bank of its obligations under, the Notes and the
Indenture do not contravene any existing provision of applicable law or result in a breach (whether after notice or lapse of time or both) of any of the terms, conditions or provisions of the *Bank Act* (Canada) or the by-laws of the Bank.

The opinion set forth in paragraph 3 above as to the enforceability of the Indenture is subject to the qualifications that:

(i) enforceability may be limited by the *Canada Deposit Insurance Corporation Act* (Canada), the *Winding-up and Restructuring Act* (Canada) and bankruptcy, insolvency, reorganization, receivership, preference, moratorium, arrangement or winding-up laws or other similar
laws affecting the enforcement of creditors' rights generally;

(ii) enforceability may be limited by equitable principles, including the principle that equitable remedies such as
specific performance and injunction may only be granted in the discretion of a court of competent jurisdiction;

(iii) pursuant to the *Currency Act* (Canada), a judgment by a Canadian court must be awarded in Canadian currency and
such judgment may be based on a rate of exchange in existence on a day other than the day of payment;

(iv) the provisions for the payment of interest under the Indenture may not be enforceable if those provisions provide for
the receipt of interest by a party at a "criminal rate" within the meaning of Section 347 of the *Criminal Code* (Canada); and

------

![LOGO](g12742g13l28.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(v) enforceability will be subject to the limitations contained in the *Limitations Act, 2002* (Ontario), and we
express no opinion as to whether a court may find any provision of the Indenture to be unenforceable as an attempt to vary or exclude a limitation period under that Act.

This opinion is rendered solely in connection with the transactions covered hereby, is limited to the matters stated herein, and no opinions may be implied or inferred beyond matters expressly stated herein.

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 6-K to be incorporated by reference in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the United States Securities Act of 1933.

Yours truly,

/s/ Osler, Hoskin & Harcourt LLP
