CECO ENVIRONMENTAL TO RESTATE 2000 - 2003 FINANCIAL STATEMENTS NET INCOME WILL BE ADJUSTED DOWN FOR THE YEARS ENDED DECEMBER 31, 2000 - 2003. HOWEVER THE ERROR IN 2004 WILL HAVE A POSITIVE AFFECT ON EARNINGS IN 2004. THERE WILL BE NO CHANGES IN OUR CASH FLOW FROM OPERATIONS AS A RESULT OF THE RESTATEMENTS.

NEW YORK, February 8, 2005 - CECO Environmental Corp (CECE -NASDAQ) reported today that its in-house accounting staff has discovered an accounting error in the spreadsheet calculations used by the Company's construction division for its 'percentage of completion' accounting.

The net effect to the financials will be a cumulative reduction in revenue of $1,969,000 over the four year period from January 1, 2000 to December 31, 2003 with an equivalent charge to pre-tax net income for the same period. None of the charges will affect any of CECO's actual cash positions.

The error has a favorable effect in the current year, 2004, as the Company understated revenues as our backlog was declining and therefore, the error is reversing. This will add approximately $180,000 to CECO's 2004 income before taxes for the nine months ended September 30, 2004. Final 2004 numbers have not yet been reported. As soon as practicable, the Company will file an amended Report on Form 10-K for the year ended December 31, 2003 and amended reports on Form 10-Q for the first three quarters of 2004 to include restatements of the financial statements included in those reports to reflect the error.

CECO also stated that this error has not affected its cash flow from operations and does not affect the borrowing base calculation used for purposes of determining the amount CECO is permitted to borrow under its current loan agreement.

Phillip DeZwirek, Chairman and CEO of CECO stated that "our in-house accounting staff discovered this miscalculation and immediately reported it to our independent auditors. As our business expands it is important to know that our Sarbanes-Oxley compliance preparation is working. This accounting restatement has a negative affect on earnings historically and a positive affect on earnings for 2004. It has no effect on the continuing progress in CECO's business which is maintaining its momentum."
