FOR IMMEDIATE RELEASE

FIRSTSERVICE ANNOUNCES NORMAL COURSE ISSUER BID

TORONTO, Ontario, May 31, 2005 - FirstService Corporation (TSX: FSV.SV; Nasdaq: FSRV) (“FirstService”) announced today that the Toronto Stock Exchange (the “TSX”) has accepted a notice filed by FirstService of its intention to make a normal course issuer bid (the “NCIB”). A similar notice has also been filed with the Ontario Securities Commission.

The notices provide that FirstService may, during the 12 month period commencing June 7, 2005 and ending June 6, 2006, purchase through the facilities of the TSX or Nasdaq National Market (“Nasdaq”) for cancellation up to 2,646,000 subordinate voting shares in total, being approximately 10% of the “public float”. Purchases of subordinate voting shares through Nasdaq will be made in the normal course and will not, during the 12 month period ending June 6, 2006 exceed, in the aggregate, 5% of the issued and outstanding subordinate voting shares of FirstService as at the commencement of the period. The price which FirstService will pay for any such shares will be the market price at the time of acquisition. The actual number of subordinate voting shares which may be purchased pursuant to the NCIB and the timing of any such purchases will be determined by senior management of FirstService.

There are 28,879,094 subordinate voting shares and 1,325,694 multiple voting shares of FirstService currently outstanding.

FirstService believes that its subordinate voting shares may from time to time trade in a price range that does not adequately reflect the value of such shares in relation to the business of FirstService and its future business prospects. As a result, depending upon future price movements and other factors, FirstService believes that its outstanding subordinate voting shares may represent an attractive investment to FirstService. Furthermore, the purchases are expected to benefit all persons who continue to hold subordinate voting shares by increasing their equity interest in FirstService.

During the preceding twelve month period, FirstService has purchased for cancellation an aggregate of 218,072 subordinate voting shares at an average price of US$12.38 per share through the facilities of the TSX and Nasdaq.
