  Item 4. Description of Securities.
  Not applicable.
  Item 5. Interests of Named Experts and Counsel.
  Not applicable. No original issuance Common Shares are to be registered hereunder, therefore no opinion of counsel regarding the legality of the Common Shares
  being registered hereunder is required.
  Item 6. Indemnification of Directors and Officers.
  Subject to any limitations contained in the Insurance Companies Act (Canada), S.C. 1991, c.47, as amended, the
  by-laws
  of the Registrant provide that the Registrant shall indemnify a director or an officer, a former director or officer or any person who acts or acted, at the Registrant's request, as a director or officer of, or in a similar capacity for,
  another entity, and each of such person's heirs and personal representatives, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by such person in respect of any
  civil, criminal, administrative, investigative or other proceeding in which such person is or was involved because of that association with the Registrant or such other entity, if (a) such person acted honestly and in good faith with a view to
  the best interests of, as the case may be, the Registrant or such other entity, and (b) in the case of a criminal or administrative action or proceeding enforced by a monetary penalty, such person had reasonable grounds for believing that their
  conduct was lawful. The
  by-laws
  also provide that the Registrant may enter into agreements evidencing its indemnity in favor of the foregoing persons to the full extent permitted by law.
  The Registrant has entered into indemnification agreements with a number of its officers and directors under which the Registrant has agreed to indemnify them
  against costs, charges, fines and expenses, including amounts paid to settle an action or satisfy a judgment, reasonably incurred by an officer or director in respect of any civil, criminal or administrative action or proceeding to which such person
  is made a party by reason of being or having been a director or officer of the Registrant, subject to any limitations contained in the Insurance Companies Act (Canada), S.C. 1991, c.47, as amended. The Registrant also has entered into similar
  agreements with individuals who serve at the written request of the Registrant as a director, officer employee, trustee, agent or fiduciary of another entity.

  Item 9. Undertakings.
  (a)
  The undersigned Registrant hereby undertakes:
  (1)
  To file, during any period in which offers or sales are being made, a post-effective amendment to this
  registration statement:
  (a)
  To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
  (b)
  To reflect in the prospectus any facts or events arising after the effective date of this registration
  statement (or the most recent post-effective amendment hereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement;
  (c)
  To include any material information with respect to the plan of distribution not previously disclosed in this
  Registration Statement or any material change to such information in this Registration Statement;
  provided,
  however,
  that paragraphs (a)(1)(a) and (a)(1)(b) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the
  Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference into this Registration Statement.
  (2)
  That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective
  amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
  (3)
  To remove from registration by means of a post-effective amendment any of the securities being registered which
  remain unsold at the termination of the offering.
  (a)
  The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the
  Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual
  report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
  (b)
  Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to
  directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in
  such Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant
  in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has
  been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication
  of such issue.
  SIGNATURES
  Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the
  requirements for filing this Registration Statement on Form
  S-8
  and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Toronto,
  Province of Ontario, Canada, on this 13
  th
  day of February, 2025.
