Stantec announces renewal of Normal Course Issuer Bid

EDMONTON AB (May 28, 2007) TSX:STN; NYSE:SXC

Stantec Inc. announced today that a Notice of Intention to renew a Normal Course Issuer Bid has been filed with, and accepted by, the Toronto Stock Exchange, pursuant to which Stantec may purchase up to 2,279,496 of its common shares, representing approximately 5% of the shares. Stantec had a total of 45,589,934 common shares outstanding as at May 15, 2007. The purchases may commence on June 1, 2007, and will terminate no later than May 31, 2008. Stantec will make the purchases in accordance with the rules and policies of the TSX, and the prices that Stantec will pay for any common shares will be the market price of such shares at the time of acquisition. Stantec will make no purchases of common shares other than open-market purchases.

Stantec believes that, from time to time, the market price of its common shares does not fully reflect the value of its business and its future business prospects. As a result, Stantec believes at such times that its outstanding common shares represent an attractive investment and an appropriate and desirable use of its available funds. Stantec also believes that the purchase of its common shares may be advisable, periodically, to offset the dilution resulting from the exercise of options and the dilution that occurs as a result of common shares issued in connection with acquisitions. Any common shares purchased by Stantec will be cancelled.

As at May 15, 2007, pursuant to its normal course issuer bid in place since June 1, 2006, Stantec has purchased 51,600 Common Shares at an average price of $19.65 per share.
