A proxy returned by a stockholder which is not subsequently revoked will be voted in accordance with the instructions indicated thereon.

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. Shares represented by a proxy in which authority to vote for any matter considered is "withheld," a proxy marked "abstain" or a proxy as to which there is a "broker non-vote" will be considered present at the meeting for purposes of determining a quorum. Required Vote to Elect Directors Directors will be elected by a plurality of the votes cast at the Annual Meeting, meaning the 6 nominees receiving the most votes will be elected. Only votes cast for a nominee will be counted. Unless indicated otherwise by your proxy, the shares will be voted for the 6 nominees named in this proxy statement. Instructions on the accompanying proxy to withhold authority to vote for one or more of the nominees will result in those nominees receiving fewer votes but will not count as a vote against the nominees.

CHANGES IN CONTROL CECO is not aware of any current arrangement(s) that may result in a change in control of CECO. However, we completed a sale of shares of common stock and warrants to a group of accredited investors (the "Investors") led by Crestview Capital Fund, L.P., a Chicago-based private investment fund. Under the Subscription Agreement ("Subscription Agreement") we entered into with the Investors, we are required to issue to such Investors additional shares for every $100,000 our EBITDA for fiscal year 2002 is below $7,800,000 for a maximum of 826,802 additional shares. The Investors, therefore, could potentially own up to 19% of CECO common stock if our EBITDA is significantly below $7,800,000, assuming the exercise of their warrants. In such event, such group could significantly influence our business. COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT 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 2001, 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, 2001, 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 leased its principal office. The lease was a triple net lease, with annual rent in the amount of approximately $88,000 for 2001. The lease terminated July 31, 2002 and we did not renew the lease. As a condition to obtaining the Bank Facility, CECO placed $5 million of subordinated debt. Green Diamond 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. Actual payment is subject to the subordination agreement with the banks providing the Bank Facility. As of August 15, 2002, the notes evidencing the $5,000,000 of subordinated debt, including the Green Diamond note, were amended to be convertible notes. The principal, but not the interest, of each note is convertible, at the election of the holder, into the Common Stock of CECO at a conversion price of $2.00 per share. Five million shares of Common Stock have been reserved for issuance upon conversion of the notes. The Audit Committee, in addition to the Board of Directors, approved the transaction. 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. Green Diamond was issued 800,000 of such warrants. Green Diamond exercised the warrants on December 21, 2001 for all 800,000 shares. During the fiscal year ended December 31, 2001, CECO reimbursed Can-Med Technology d/b/a Green Diamond Oil Corp. $5,000 per month for use of the space and other office expenses of CECO's Toronto office.

Richard J. Blum, Phillip DeZwirek and Jason Louis DeZwirek, all executive officers, have participated in deliberations of the Board of Directors concerning executive officer compensation. Our employee compensation policy is to offer a package including a competitive salary, competitive benefits, and an efficient workplace environment. We also encourage broad-based employee ownership of CECO stock through our Stock Purchase Plan in which most employees are eligible to participate. Our officers may also participate in the Stock Purchase Plan. The Company's compensation policy for officers is similar to that for other employees, and is designed to promote excellent performance and attainment of corporate and personal goals. The Board of Directors (comprised of three executive officers and two, and as of August 14, 2002, three, non-employee directors) reviews and approves individual officer salaries and bonuses. Officers of CECO are paid salaries in line with their responsibilities. These salaries are structured so they are comparable with salaries paid by competitors in the relevant industries. Officers (and other employees) are also eligible to receive stock option grants, which are intended to promote success by aligning employee financial interests with long-term shareholder value. Stock option grants are based on various subjective factors primarily relating to the responsibilities of the individual officers, and also to their expected future contributions and prior option grants. The Board of Directors annually reviews and approves the compensation of Phillip DeZwirek, Chief Executive Officer and Chairman of the Board. His compensation is tied to revenues and profits, strategic goals, capital raising efforts, and his general performance. In addition, Mr. DeZwirek is a significant shareholder in CECO; to the extent his performance translates into an increase in the value of CECO's stock, all shareholders, including Mr. DeZwirek, share the benefit. Employment Contracts Richard J. Blum entered into an Employment Agreement dated December 7, 1999 with CECO Group. The Employment Agreement, which was recently extended for an additional year, has a term through December 7, 2005. Either party may terminate the Employment Agreement for cause. Mr. Richard Blum's base salary is set annually, at the Board's discretion, and is currently $228,400 per year. In addition to his base salary, Mr. Richard Blum is entitled to a bonus, depending upon whether CECO exceeds certain targets, and four weeks paid vacation. 12

David D. Blum entered into an Employment Agreement dated December 7, 1999 with Kirk & Blum. The Employment Agreement, which was recently extended for an additional year, has a term through December 7, 2005. Either party may terminate the Employment Agreement for cause. Mr. David Blum's base salary is set annually, at the Board's discretion, and is currently $170,750 per year. In addition to his base salary, Mr. David Blum is entitled to a bonus, depending upon whether CECO exceeds certain targets, and four weeks paid vacation. Options In consideration for Jason Louis DeZwirek's valuable service to CECO as an officer and director, CECO granted Mr. DeZwirek options on October 5, 2001 to purchase up to 25,000 shares of CECO's common stock, which are exercisable at any time between April 5, 2002 and October 5, 2011, inclusive, at a price of $2.01, the closing price of CECO's common stock on October 5, 2001. Such options are not transferable other than by will or the laws of descent. Compensation Under CECO Stock Option Plan and Stock Purchase Plans Stock Option Plan Our Stock Option Plan was adopted by our board of directors on October 1, 1997 and approved by the shareholders on September 10, 1998. This plan provides for the grant of incentive stock options to our employees and nonstatutory stock options to our employees, consultants, advisors and directors. The number of shares of common stock reserved under the Stock Option Plan are 1,500,000. Of these shares, 182,500 shares were subject to outstanding options and 1,317,500 shares were available for future grant as of March 15, 2002. No options have been exercised as of March 15, 2002. A committee of our board administers the stock plan and determines the terms of awards granted, including the exercise price, the number of shares subject to individual awards and the vesting period of awards. Directors Grivas and Wright currently serve on such committee. In the case of options intended to quality as "performance-based compensation" within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), the committee will consist of two or more "outside directors" within the meaning of Section 162(m) of the Code. The committee determines the exercise price of options granted under the Stock Option Plan, but with respect to nonstatutory stock options intended to qualify as "performance-based compensation" within the meaning of Section 162(m) of the Code and all incentive stock options, the exercise price must at least be equal to the fair market value of our common stock on the date of grant. The term of an incentive stock option may not exceed ten years, except that with respect to any participant who owns 10% of the voting power of all classes of our outstanding capital stock, the term must not exceed five years and the exercise price must equal at least 110% of the fair market value on the grant date. The committee determines the term of all other options. In the year 2001, options to purchase 35,000 shares of stock of CECO were granted under the Stock Option Plan. On October 5, 2001, Richard J. Blum, in consideration for his valuable services as an executive officer and director was granted an option under the Stock Option Plan to purchase up to 25,000 shares of stock of CECO. The option becomes exercisable on April 5, 2002 and expires on October 5, 2011. The exercise price per share is $2.01, the closing price for CECO's common stock on the date of the grant. On October 5, 2001, Donald Wright, in consideration for his valuable services as a director of CECO, was granted an option under the Plan to purchase up to 10,000 shares of stock of CECO. The option becomes exercisable on April 5, 2002 and expires on October 5, 2011. The exercise price per share is $2.01, the closing price for CECO's common stock on the date of the grant. Stock Purchase Plan On September 21, 1999, the Board of Directors of CECO adopted the Stock Purchase Plan which was approved by the stockholders on November 16, 1999. Employees, other than certain part-time employees, are 13

eligible to participate in the Stock Purchase Plan, which provides employees the opportunity to purchase stock of CECO at a discounted price. The maximum number of shares of common stock of CECO that will be offered under the Stock Purchase Plan is 1,000,000. Such shares will be offered in nine separate consecutive offerings, which commenced October 1, 1999, with the final offering terminating on September 30, 2004. The purchase price per share will be the lesser of 85% of the market price of the stock on the last business day of the offering or 85% of the market price of the stock on the offering date. Payment for the stock under the Stock Purchase Plan is paid through employee payroll deductions. The Stock Purchase Plan is administered by CECO's board of directors, however, the board of directors may delegate its authority to a committee of the board or an officer of CECO. Directors Grivas and Wright currently administer the Stock Purchase Plan. As of August 1, 2002, 53,144 shares of stock have been issued under the Stock Purchase Plan; 6,241 of which have been issued to Mr. Richard Blum to date, and 6,790 of which have been issued to Mr. David Blum to date. No other shares of stock under the Stock Purchase Plan have been issued to an executive officer or director of CECO. Director Compensation The directors of CECO received no consideration for serving in their capacity as directors of CECO or as members of any committee of the Board during its last fiscal year, other than Donald Wright, Richard J. Blum and Jason Louis DeZwirek who received options to purchase 10,000, 25,000 and 25,000 shares of common stock, respectively. Phillip DeZwirek, a director, receives compensation in his capacity as an executive officer. 14

Stock Performance Graph The line graph below compares the annual percentage change in CECO's cumulative total shareholder return on its Common Stock with the cumulative total return of the Russell 2000 Stock Index (a broad-based market index) and The Dow Jones Industry Group--Pollution Control (a "Peer Group Index") for the five-year period ending December 31, 2001. The graph and table assumes $100 invested on December 31, 1996 in the Company's Common Stock, the Russell 2000 Stock Index and The Dow Jones Industry Group--Pollution Control and that all dividends were reinvested. The Dow Jones Industry Group--Pollution Control Index total return is weighted by market capitalization. The Dow Jones Industry Group--Pollution Control reflects CECO's performance against pollution control businesses, the Company's principal industry group, and provides an appropriate indicator of cumulative total shareholder returns. There are 60 companies included in this industry group. Based on an Initial Investment of $100 on December 31, 1996, with Dividends Reinvested [CHART] Dec. Dec. Dec. Dec. Dec. Dec.

PROPOSAL II APPROVE AND AUTHORIZE ADDITIONAL SHARES TO CERTAIN INVESTORS The Transaction and Reason for Issuance The shareholders are being asked to approve the issuance of 114,228 shares of Common Stock of CECO to the Investors upon the occurrence of certain events. On December 31, 2001, we completed the sale of 706,668 shares of our common stock, at a price of $3.00 per share, and the issuance of warrants to purchase 353,334 shares of our common stock at an initial price of $3.60 per share (the "Warrants"), to the Investors. The proceeds raised from the offering were used to pay down our credit facility. Pursuant to the Subscription Agreement, we are required to issue additional shares of CECO Common Stock at no additional cost to the Investors if our earnings before interest, taxes, depreciation and amortization ("EBITDA") for our 2002 fiscal year is less than $7,800,000 (based on the consolidated financial statements prepared in accordance with GAAP (except that adjustments to earnings attributable to the issuance of the Warrants or any options/warrants issued to The Shemano Group will not be taken into account), without any "pro forma adjustments" and as indicated on our Form 10-K, including any amendment thereto). We will be required to issue a number of shares to each Investor equal to 1.5% of the initial number of shares issued to such Investor for every $100,000 under $7,800,000 that our EBITDA is. For instance, if our EBITDA is $7,550,000 for fiscal 2002 and an Investor initially received 100,000 shares, then we would be required to issue an additional 3,750 Shares to such Investor at no additional cost to such Investor. If our EBITDA is zero for fiscal year 2002, we would be required to issue 826,802 additional shares in the aggregate to the Investors. We will also be required to use our best efforts to register all such shares on a registration statement with the SEC. However, we are prohibited under NASD Rule 4350 from issuing common stock or warrants equal to 20% or more of our common stock outstanding prior to the issuance for less than market value, without receiving shareholder approval. The stock was issued to the Investors at a price below market value. On the closing date of the sale of the 706,668 shares of common stock, the closing price for our common stock based upon the last sale on such day as quoted on Nasdaq was $3.30. The sale price for the shares was $3.00 per share. Under the terms of the Subscription Agreement we are not required to issue to the Investors in excess of 1,772,576 shares in the aggregate (including shares underlying the Warrants), which represented 19.9% of our Common Stock at such time, without first obtaining shareholder approval. The aggregate amount of shares we would be required to issue if our EBITDA is zero is 1,886,804, and the terms of the Subscription Agreement obligate us to seek shareholder approval for such issuance. Therefore, we are asking CECO's shareholders to approve the issuance of 114,228 shares of Common Stock (the "Additional Shares") of CECO to the Investors. Such Additional Shares would be issued only if and to the extent required under the Subscription Agreement. Effect of Issuance Upon Existing Shareholders Set forth below is a table listing each Investor entitled to additional shares if our EBITDA for 2002 is below $7,800,000, and with respect to each such Investor, the number of shares initially issued to such shareholder, the number of shares underlying the warrants issued to such shareholder, the maximum number of additional shares to be issued if shareholder approval is not received, the total number of shares that may be issued without shareholder approval (including initially issued shares), the maximum number of additional shares that may be issued if shareholder approval is obtained, and the total maximum number of shares that could be issued if shareholder approval is obtained (including initially issued shares). 16

However, management believes that the issuance of the Additional Shares does not substantially increase such risk, as the Investors in the aggregate would own 19% of the Common Stock if the Additional Shares are issued instead of 17.8% of the Common Stock if the Additional Shares are not issued, assuming in both cases exercise of their Warrants. Further, if our EBITDA for our 2002 fiscal year is sufficient, we may not have to issue any Additional Shares. The Board of Directors determined that the terms of the deal with the Investors, including if necessary the full issuance of 862,002 shares, was in the best interests of CECO, and therefore, recommends a vote for the issuance of the Additional Shares. Vote Required for Approval Approval of the issuance of the Additional Shares to the Investors will require the affirmative vote of the majority of the shareholders present in person or by proxy, however, the shares held by the Investors will not be counted for this proposal. Each of Phillip DeZwirek, Green Diamond, Introtech and Icarus have agreed to vote their shares in favor of the proposal to issue the Additional Shares. As of the record date for the Annual Meeting, such parties control the right to vote 3,857,223 shares, representing 40.25% of the outstanding Common Stock. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE ISSUANCE OF ADDITIONAL SHARES TO THE INVESTORS. PROPOSAL III 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, 2002. 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 fiscal year ended December 31, 1999 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to 17

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. Audit Fees Deloitte billed CECO $115,901 and Margolis billed CECO $4,000 for the professional services rendered for the audit of CECO's annual financial statements for fiscal year 2001 and the reviews of the financial statements included in CECO's Quarterly Reports on Form 10QSB filed for the first three quarters of 2001. Financial Information Systems Design and Implementation Fees Deloitte did not render professional services for the design and implementation of financial information systems to CECO during fiscal year 2001. All Other Fees Deloitte billed CECO $58,350 for all professional services rendered during fiscal year 2001 other than audits, reviews and financial information systems design and implementation. The Audit Committee has considered whether the provision of services by Deloitte other than the audit of the financial statements of CECO for the fiscal year 2001 and the review of the financial statements for the third quarter of the fiscal year 2001 is compatible with maintaining Deloitte's independence. 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 2002. ADDITIONAL INFORMATION OTHER MATTERS As of the date of this Proxy Statement, the Board of Directors knows of no matters which will be presented for consideration at the Annual Meeting other than the proposals set forth in this Proxy Statement. If any other matters properly come before the Annual Meeting, it is intended that the persons named in the proxy will vote the shares they represent as the Board of Directors may recommend. A COPY OF CECO'S ANNUAL REPORT ON FORM 10-K FOR THE FISCAL YEAR ENDED DECEMBER 31, 2001, AS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, 18

EXHIBIT A Independent Auditors' Report To the Board of Directors and Shareholders CECO Environmental Corp. We have audited the accompanying consolidated balance sheet of CECO Environmental Corp. and subsidiaries (the "Company") as of December 31, 2001 and 2000, and the related consolidated statements of operations, shareholders' equity, and cash flows for the year then ended. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2001 and 2000, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.
