EXHIBIT 10.41

RESTRICTED STOCK AWARD AGREEMENT

THIS RESTRICTED STOCK AWARD AGREEMENT (the
Agreement) is made and entered into as of July 2, 2007, by and between CECO Environmental Corp., a Delaware corporation (the Company), and Ronald E. Krieg (the Participant) relating to
the grant and issuance of shares of Common Stock of the Company under the CECO Environmental Corp. 2007 Equity Incentive Plan (the Plan).

Statement of Purpose

WHEREAS, the Company desires to grant to the Participant, and the Participant
accepts the grant of, 2,000 shares of Common Stock (the Shares);

WHEREAS, the Company has duly made all determinations
necessary or appropriate in connection with the grant of the Shares hereunder.

NOW, THEREFORE, in consideration of the premises and the
mutual covenants herein contained, the parties hereto hereby agree as follows:

1. Definitions. Unless otherwise defined
herein, capitalized terms in this Agreement shall have the same meaning as defined in the Plan.

2. Grant, Vesting and Settlement of
Restricted Shares

(a) Grant. As of July 2, 2007, the Company hereby grants and issues to the Participant, and the
Participant hereby accepts the grant of the Shares in such number as is specified in attached Exhibit A. Concurrent with the execution and delivery of the Agreement, the Company will cause the stock certificates representing the Shares to be issued
in Participants name. To the extent the Participant hereby acquires the Shares and the Shares are not fully vested as of the date hereof, such Shares shall constitute Restricted Shares and shall be subject to all of the
restrictions described herein. Stock certificates representing Restricted Shares shall be held by the Company until such time as the Shares vest.

(b) Vesting and Settlement. The Restricted Shares shall cease to constitute Restricted Shares, and shall become unrestricted Shares, pursuant to the vesting schedule attached as Exhibit A.

3. Restriction on Transfer; Legend.Restricted Shares or any interest therein may not be directly or indirectly sold, transferred, pledged,
hypothecated, or otherwise disposed of. The Restricted Share certificates shall bear the following legend:

The shares
represented by this certificate are subject to restrictions on transfer and may not be sold, exchanged, transferred, pledged, hypothecated or otherwise disposed of except in accordance with and subject to all of the terms and conditions of a
Restricted Stock Award Agreement dated as of July 2, 2007, a copy of which the Company shall furnish to the holder of this certificate upon request and without charge.



---

When the restrictions on any Shares lapse, the Corporation shall cause a replacement stock certificate
for those Shares, without the legend referred to above, to be issued and delivered to Participant as soon as practicable.

4. Tax
Consequences.The Company shall not be liable or responsible in any way for any and all tax (including any withholding tax) consequences relating to the Shares, and the Participant agrees to undertake to determine, and be responsible for,
any and all tax (including any withholding tax) consequences to himself or herself with respect to the Shares. Notwithstanding any other provision of this Agreement, the Shares, shall not be released to the Participant unless, the Participant shall
have paid to the Company, or made arrangements satisfactory to the Company regarding the payment of, any Federal, state, local or foreign taxes of any kind required by law to be withheld with respect to the grant of the Shares or the lapse of
restrictions otherwise imposed by this Agreement.

5. Section 83(b) Election. The Participant understands that
Section 83 of the Code may tax as compensation income the difference between the amount paid for the Restricted Shares, if any, and the fair market value of the Restricted Shares as of the date any restrictions on the Restricted Shares lapse in
the absence of an election under Section 83(b) of the Code. In this context, restriction means the forfeitability of the Restricted Shares pursuant to the terms of this Agreement. In the event the Common Shares are registered under
the Securities Exchange Act of 1934, as amended (the Exchange Act), restriction with respect to the officers, directors, and 10% stockholders may also mean the six-month period after the acquisition of the Restricted Shares
during which sales of certain securities by such officers, directors, and ten percent (10%) stockholders would give rise to liability under Section 16(b) of the Exchange Act. The Participant understands that he may elect to be taxed at the
time the Participant receives the Restricted Shares and while the Restricted Shares are subjected to restrictions rather than waiting to be taxed on the Restricted Shares when and as the restrictions lapse. The Participant realizes that he may
choose this tax treatment by filing an election under Section 83(b) of the Code with the Internal Revenue Service within thirty (30) days from the date hereof and by filing a copy of such election with his tax return for the tax year in
which the Restricted Shares were subjected to the restrictions. THE PARTICIPANT ACKNOWLEDGES THAT IT IS THE PARTICIPANTS SOLE RESPONSIBILITY AND NOT THE COMPANYS TO TIMELY FILE THE ELECTION UNDER SECTION 83(B) OF THE CODE. A COPY OF SUCH
ELECTION MUST BE FILED WITH THE COMPANY. THE PARTICIPANT ACKNOWLEDGES THAT HE SHALL CONSULT HIS OWN TAX ADVISERS REGARDING THE ADVISABILITY OR NON-ADVISABILITY OF MAKING THE ELECTION UNDER SECTION 83(B) OF THE CODE AND ACKNOWLEDGES THAT HE SHALL NOT
RELY ON THE COMPANY OR ITS ADVISERS FOR SUCH ADVICE.

6. Voting. Participant shall have the rights and privileges of a
stockholder of the Company as to the Shares, including the right to receive dividends and the right to vote such Shares.

7.Intentionally omitted.
