The opinion expressed in paragraph 3 is based on the assumption that the Indenture has been duly authorized, executed and delivered by, and is enforceable in accordance with its terms against, the Trustee.

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

1. The Bank validly exists as a Schedule I bank under theBank 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, to issue and deliver the Common Shares into which the Notes may be converted upon a NVCC Automatic Conversion (as defined in the Indenture), and to execute, deliver and perform its obligations under the Indenture.

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. All necessary corporate action has been taken by the Bank to authorize and reserve for issuance the Common Shares into which the Notes may be converted upon a NVCC Automatic Conversion (as defined in the Indenture) and such Common Shares, when duly issued in accordance with the Indenture, will be validly issued, fully paid andnon-assessable shares. The Notes, with respect to the provisions thereof governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, constitute a legal, valid and binding obligation of the Bank enforceable in accordance with their terms.

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, and the issuance and delivery of the Common Shares upon a NVCC Automatic Conversion (as defined in 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 theBank Act(Canada) or theby-laws of the Bank.

The opinions set forth in paragraphs 2 and 3 above as to the enforceability of the Notes and the Indenture, respectively, are subject to the qualifications that:

(i) enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, preference, moratorium, arrangement orwinding-up laws or other similar laws affecting the enforcement of creditors’ rights generally;

(iii) enforceability will be subject to the limitations contained in theLimitations 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.
