A stockholder returning a proxy may revoke it at any time prior to exercise of the proxy at the Annual Meeting by executing and delivering a later-dated proxy which is voted at the Annual Meeting, by voting in person at the Annual Meeting or by delivering written notice to the Secretary of CECO at any time before the proxy is exercised. A proxy returned by a stockholder which is not subsequently revoked will be voted in accordance with the instructions indicated thereon. If no instructions are indicated on a duly executed and returned proxy, the shares represented by the proxy will be voted FOR the ratification of the 5 nominees for director proposed by the Board of Directors and set forth herein, FOR the ratification of the appointment of Deloitte & Touche LLP as the independent public accountants of CECO for fiscal year 2000, and in accordance with the judgment of the persons named in the proxy as to such other matters as may properly come before the Annual Meeting. The mailing address of the principal office of CECO is 505 University Avenue, Toronto, Ontario CANADA M5G 1X3.

As of the Record Date, there were 8,037,753 shares of CECO Common Stock ("Common Stock") outstanding and entitled to vote at the Annual Meeting, each such share being entitled to cast one vote. Votes present in person or by proxy at the Annual Meeting will be tabulated by the election inspectors appointed for the meeting and will determine whether or not a quorum is present. Abstentions and broker non-votes are counted for purposes of determining the presence of a quorum for the transaction of business. The presence in person or by proxy of stockholders entitled to cast a majority of all the votes entitled to be cast at the meeting will constitute a quorum. If there is not a quorum at the Annual Meeting, the stockholders present in person or represented by proxy at the meeting have the power to adjourn the meeting until such time as there is a quorum. At such time as there is a quorum of stockholders present in person or represented by proxy, the Annual Meeting will reconvene without notice to stockholders, other than an announcement at the meeting prior to adjournment, unless the adjournment is for more than 60 days after the Record Date or a new record date has been set.

CHANGES IN CONTROL CECO is not aware of any current arrangement(s) that may result in a change in control of CECO. COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT Steven I. Taub, the former President of Filters, failed to timely file a Form 4 to report the sale of 500 shares of stock of CECO. Such transaction was reported in a late Form 4. Except for Mr. Taub, CECO is not aware of any persons who beneficially own or owned more than 10 percent of the outstanding common stock of CECO or any officer, director or other person subject to the requirements of Section 16 of the Securities Exchange Act of 1934 who, during the fiscal year 1999, failed to file, or failed to file on a timely basis, any reports or forms required to be filed under said Section 16 or the rules and regulations promulgated thereunder. CERTAIN TRANSACTIONS Since January 1, 1998, the following transactions have occurred in which persons who, at the time of such transactions, were directors, officers or owners of more than 5% of CECO's common stock, had a direct or indirect material interest. Andrew Halapin, former President of Busch, is the beneficial owner of the building in which Busch leases its principal office. The lease is a triple net lease, with annual rent in the amount of $82,398. CECO purchased shares of Peerless Manufacturing Company stock. Part of the funds used to purchase such stock were borrowed from Can-Med. Can-Med is owned 50.1% by Icarus, which is owned 50% by Phillip DeZwirek (the Chairman of the Board of Directors and Chief Executive Officer of CECO) and 50% by Jason DeZwirek (a director and the Secretary of CECO). As of December 31, 1999 the amount outstanding on such loan was $800,000. The loan is payable upon demand and accrues interest at a rate of 10%. As of August 31, 2000 such loan has been repaid in full. 6

As a condition to obtaining a bank loan facility with PNC Bank, National Association, The Fifth Third Bank and Bank One, N.A. (the "Bank Facility"), CECO placed $5 million of subordinated debt. Can-Med provided $4,000,000 of the subordinated debt. The promissory notes which were issued to evidence the subordinated debt provide that they accrue interest at the rate of 12% per annum, payable semi-annually, subject to the subordination agreement with the banks providing the Bank Facility. In consideration for the subordinated lenders making CECO the subordinated loans, CECO issued to the subordinated lenders warrants to purchase up to 1,000,000 shares of CECO's common stock for $2.25 per share, the closing price of CECO's common stock on the day that the subordinated lenders entered into an agreement with CECO to provide the subordinated loans. Can-Med was issued 800,000 of such warrants. The warrants are exercisable from June 6, 2000 until December 7, 2009. In connection with such warrants, the subordinated lenders, including Can-Med, were granted certain registration rights with respect to their warrants and shares of common stock of CECO into which the warrants are convertible. On July 5, 2000, CECO purchased 441,297 shares of CECO from Steven I. Taub, former President, Chief Executive Officer and director of Filters for $2.125 per share. Such purchase was in connection with the termination of Mr. Taub's employment with Filters. CECO, as part of such termination, also purchased 124,703 shares of CECO stock from Hilary Taub, the former wife of Mr. Taub, for $2.125 per share. Both purchases were made pursuant to the terms of Stock Sale Agreements dated July 5, 2000. In 2000, as of September 15th, CECO has purchased 50,000 shares of CECO stock in the market; such stock has been retired. EXECUTIVE COMPENSATION Except for the compensation described below, neither CECO nor any of its subsidiaries paid, set aside or accrued any salary or other remuneration or bonus, or any amount pursuant to a profit-sharing, pension, retirement, deferred compensation or other similar plan, during its last fiscal year, to or for any of CECO's executive officers or directors. Warrants In consideration for Philip DeZwirek's valuable service to CECO as an officer and director, CECO granted Mr. DeZwirek warrants (i) on January 22, 1999 to purchase up to 500,000 shares of CECO's common stock, which are exercisable at any time between July 22, 1999 and January 22, 2009 inclusive at a price of $3.00, the closing price of CECO's common stock on January 22, 1999 and (ii) on August 14, 2000 to purchase up to 500,000 shares of CECO's common stock, which are exercisable at any time between August 14, 2001 and August 14, 2010 inclusive at a price of $2.0625, the closing price of CECO's common stock on August 14, 2000 (each such grant of warrants a "Warrant Grant"). All of such warrants grant the holders thereof "piggyback registration rights", i.e. the right to participate in any registration of securities by CECO other than a registration statement in connection with a merger or pursuant to registration statements on Forms S-4 or S-8. Additionally, the holders of a majority of the shares underlying the warrants and the warrants for each Warrant Grant have the right on two occasions to have CECO prepare and file with the Securities and Exchange Commission a registration statement and such other documents as may be necessary for such holders to effect a public offering of the shares underlying the warrants previously issued or to be issued upon the effectiveness of such registration statement. CECO is however required to pay the expenses of only one of such registrations for each Warrant Grant. With respect to each Warrant Grant, the right to demand such registrations expires 10 years from the date of the Warrant Grant, or upon the happening of certain other conditions. 7

On December 7, 1999 Richard J. Blum and David D. Blum were granted warrants to purchase 448,000 and 335,000, respectively, shares of CECO's stock. The exercise price for each share is $2.9375. The warrants become exercisable at the rate of 25% per year over the four years following December 7, 1999 and have a term of ten years. Stock Option Plan As of September 15, 2000, 125,000 options under the CECO Environmental Corp. 1997 Stock Option Plan have been issued since January 1, 1999, 50,000 of which were issued on January 20, 2000 to Marshall J.

PROPOSAL II APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS Subject to ratification by the stockholders at the Annual Meeting, the Board of Directors has appointed Deloitte & Touche LLP ("Deloitte") to serve as the independent public accountants of CECO for its fiscal year ending December 31, 2000. Deloitte was engaged to act as CECO's public accountants on September 28, 2000. Accordingly, the engagement of Margolis & Company P.C. ("Margolis") was discontinued effective September 28, 2000. Margolis served as the independent public accountants of CECO since 1993. Notwithstanding the appointment, the Board of Directors, in its discretion, may direct appointment of new independent auditors at any time during the year, if the Board of Directors believes that such a change would be in the best interests of CECO and its stockholders. Neither representatives of Deloitte nor Margolis are expected to be present at the Annual Meeting. If the appointment of Deloitte is not ratified by the stockholders, the Board of Directors will appoint other independent public accountants. The reports of Margolis on CECO's consolidated financial statements for each of the two fiscal years in the period ended December 31, 1999 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with the audits of CECO's consolidated financial statements for each of the two fiscal years ended December 31, 1998 and December 31, 1999 and the subsequent interim period prior to June 30, 2000, there were no disagreements between CECO and Margolis on any matters of accounting principles or practices, financial statement disclosure, or audit scope and procedures which, if not resolved to the satisfaction of Margolis, would have caused Margolis to make reference to the matter in their reports. CECO did not consult with Deloitte during the last two fiscal years in the period ended December 31, 1999 or the subsequent interim period prior to June 30, 2000 on either the application of accounting principles or type of opinion Deloitte might issue on CECO's financial statements. CECO reported the change in principal accountants on a Current Report on Form 8-K filed September 29, 2000. CECO provided Margolis with a copy of the disclosures it made in the Current Report on Form 8-K prior to the filing of the report with the Securities and Exchange Commission. Margolis has furnished CECO a copy of a letter addressed to the Securities and Exchange Commission stating that Margolis agrees with the statements made by CECO in this Proxy Statement. The affirmative vote of a majority of the votes cast on this proposal at the Annual Meeting with a quorum present is required to approve this proposal. THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS INDEPENDENT PUBLIC ACCOUNTANTS OF CECO FOR FISCAL YEAR 2000.
