 Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

#### Conflicts of Interest
Certain affiliates of the underwriters will receive at least 5% of the net proceeds of this offering in connection with the repayment of a portion of the borrowings outstanding under the Revolving Credit Facility. See “Use of Proceeds” in this prospectus supplement. Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121. In accordance with that rule, no “qualified independent underwriter” is required because the securities will be rated investment grade. Such underwriters will not confirm sales to discretionary accounts without the prior written approval of the customer.

#### Settlement
Delivery of the Notes is expected to be made against payment for the Notes on June 4, 2025, which will be the fifth business day following the date hereof (this settlement cycle being referred to as “T+5”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify alternate settlement arrangements at the time of any such trade to prevent a failed settlement and should consult their own advisers.

### ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS
We are a corporation organized under the laws of Ontario, Canada and are governed by the applicable provincial and federal laws of Canada. Certain of our officers and directors and one of the experts named in this prospectus supplement reside principally in Canada. Because we and these persons are located outside the United States, it may not be possible for you to effect service of process within the United States on us or them. Furthermore, it may not be possible for you to enforce against us or them, in the United States, judgments obtained in United States courts, because a portion of our assets and the assets of these persons are located outside the United States.

We have been advised by Bennett Jones LLP, our Canadian counsel, that there is doubt as to the enforceability,
