PART I

INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

This registration statement on Form S-8 (the “Registration Statement”) relates to securities of Enerflex Ltd., a corporation organized under the Canada Business Corporations Act (the “Registrant” or the “Company”), to be offered pursuant to the Enerflex Ltd. Share Unit Plan (the “Plan”). The Registrant will provide to all participants in the Plan the document(s) containing the information required by Part I of Form S-8, as specified in Rule 428(b)(1) promulgated by the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). In accordance with Rule 428, the Registrant has not filed such document(s) either as part of this Registration Statement on Form S-8 or as a prospectus or prospectus supplement pursuant to Rule 424 under the Securities Act. These documents and the documents incorporated by reference in this Registration Statement pursuant to Item 3 of Part II of Form S-8, taken together, constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act. The Registrant shall maintain a file of such documents in accordance with the provisions of Rule 428(a)(2) of the Securities Act. Upon request, the Registrant shall furnish to the Commission or its staff a copy or copies of all of the documents included in such file.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Except to the extent that information is deemed furnished and not filed pursuant to securities laws and regulations, all documents filed by the Registrant with the Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, subsequent to the date of this Registration Statement and prior to the filing of a subsequent post-effective amendment that indicates that all securities offered have been sold or which deregisters all securities then remaining unsold will be deemed to be incorporated by reference in this Registration Statement and to be part hereof from the date of filing of such documents. Any statement contained in any document incorporated or deemed to be incorporated by reference herein will be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement.

Item 6. Indemnification of Directors and Officers.

Under the Canada Business Corporations Act, R.S.C., 1985, c. C-44, as amended (“CBCA”), Enerflex may indemnify its directors and officers, its former directors and officers or another individual who acts or acted at Enerflex’s request as a director or officer, or an individual acting in a similar capacity, of another entity (which we refer to as an “indemnifiable person”) against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the indemnifiable person in respect of any civil, criminal, administrative, investigative or other proceeding in which the indemnifiable person is involved because of that association with Enerflex or other entity, provided that:

(i) the indemnifiable person acted honestly and in good faith with a view to the best interests of Enerflex, or, as the case may be, to the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at Enerflex’s request; and

(ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the indemnifiable person had reasonable grounds for believing that the indemnifiable person’s conduct was lawful.

Enerflex may advance funds to an indemnifiable person for the costs, charges and expenses of a proceeding referred to above; provided, however, that the indemnifiable person will repay the funds if the individual does not fulfill the above-mentioned conditions.

An indemnifiable person is also entitled to indemnity from Enerflex in respect of all costs, charges and expenses reasonably incurred by the indemnifiable person in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the indemnifiable person is subject because of the indemnifiable person’s association with Enerflex or other entity, if the indemnifiable person:

(i) was not judged by the court or other competent authority to have committed any fault or omitted to do anything that the indemnifiable person ought to have done; and

(ii) fulfills the conditions first set out above.

In the case of a derivative action, indemnity may be made only with court approval, if the indemnifiable person fulfills the requirements first mentioned above.

In addition, Enerflex may, under the CBCA, purchase and maintain insurance for the benefit of an indemnifiable person.

Under Enerflex’s By-Laws No. 1, Enerflex shall indemnify a director or officer of Enerflex, a former director or officer of Enerflex or a person who acts or acted at Enerflex’s request as a director or officer, or an individual acting in a similar capacity, of another entity, to the extent permitted by the CBCA.

Item 7. Exemption From Registration Claimed.

Not applicable.

Item 8. Exhibits.

The Exhibit Index to this Registration Statement is incorporated herein by reference as the list of exhibits required as part of this Registration Statement.

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:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in this effective registration statement; and

(iii) 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)(i) and (a)(1)(ii) of this section 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 in 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; and

(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.

(b) 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 the 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.

(c) 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 the 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 Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on our behalf by the undersigned, thereunto duly authorized, in Calgary, Alberta, on this 13^th day of March, 2026.
