FIRSTSERVICE REPORTS RECORD FIRST QUARTER RESULTS

NET EARNINGS FROM CONTINUING OPERATIONS UP 34%

$0.14 PER SHARE GAIN ON SALE OF LAWN CARE OPERATIONS

•

INCREASES FISCAL 2005 OUTLOOK

TORONTO, Canada, July 28, 2004 — FirstService Corporation (Nasdaq: FSRV; TSX: FSV) today reported record results for its first quarter ended June 30, 2004. Net earnings from continuing operations were $7.2 million (all amounts are in US dollars), a 34% increase relative to the same period last year. The Company also reported an after-tax gain of $2.2 million or $0.14 per diluted share on the sale of the assets of Greenspace Services Ltd., its company-owned lawn care operation. Greenspace has been classified as a discontinued operation for comparative purposes.

Revenues for the quarter were $171.0 million, an increase of 15% versus the first quarter of last year. Excluding the impact of acquisitions made during the past twelve months, internal revenue growth for the quarter was 8%. EBITDA for the first quarter was $18.3 million, up 17% relative to the same period a year ago, and operating earnings for the first quarter were $14.4 million, up 21% relative to the same period a year ago. See "Reconciliation of EBITDA to Operating Earnings" below. Diluted net earnings per share from continuing operations for the quarter were $0.48, up 26%, from $0.38 a year ago.

FirstService Corporation is a North American leader in the rapidly growing service sector, providing services to commercial and residential customers in the following four areas: Residential Property Management; Integrated Security Services; Consumer Services; and Business Services, including business process outsourcing and marketing support services.

SEGMENTED QUARTERLY OPERATING RESULTS

Consumer Services revenues were $30.3 million, up 32% relative to the first quarter last year. Internal growth represented 13% of the increase while the balance was from acquisitions completed during the past year. Internal growth was particularly strong at the California Closet Company franchise system and company-owned California Closets "branchise" stores. Consumer Services EBITDA was $7.5 million, an increase of $2.9 million, or 63%, versus the prior year quarter, and EBITDA margins increased to 24.9% from 20.1%.

Integrated Security Services revenues were up 13% to $34.1 million for the quarter. Internal growth contributed a 5% increase and the balance was due to the acquisition of a Florida and Texas-based security systems integrator completed in February 2004. Internal growth was driven by strong systems sales, both in Canada and the United States. Segment EBITDA was $2.6 million, or 7.5% of revenues, versus $2.1 million or 6.9% of revenues in the prior year period, with the improvement in margin primarily the result of a greater proportion of higher margin systems revenues relative to security officer revenues.

Residential Property Management revenues increased to $71.1 million, 15% over the first quarter last year. Internal growth accounted for slightly more than half of the increase, including solid growth in core management revenues, while recent acquisitions represented the balance of revenue growth. EBITDA was $6.6 million, the same amount reported last year. EBITDA growth was hampered by seasonal timing factors that are expected to reverse as the year progresses, as well as the mix of revenues between core management services and other property services.

Business Services revenues were $35.4 million, an increase of 7% versus last year's first quarter, all from internal growth. Revenues were positively impacted by fulfilment contract wins and higher transaction volumes from existing clients, but were offset by the planned decline in school textbook fulfilment volumes at the Dallas branch during the month of June as a result of government education funding cut backs this year. Due to the seasonality of the textbook fulfilment business, the lower revenues impacted EBITDA by $0.6 million. As a result, EBITDA was $3.5 million, or 9.9% of revenues, for the quarter versus $3.8 million or 11.3% of revenues in the prior year period. The Company expects that textbook fulfilment results will be impacted by a similar amount due to the same factors in the second quarter.

2

Quarterly corporate costs were $2.0 million, $0.5 million higher than in the prior year, due to Sarbanes-Oxley 404 implementation costs, additional variable compensation expense, and stock option expense.

For a reconciliation of segmented EBITDA to operating earnings, see "Segmented Revenues, EBITDA and Operating Earnings" below.

SALE OF GREENSPACE ASSETS

On April 1, 2004, at the beginning of the quarter, the Company sold the assets of its Greenspace company-owned lawn care operations. A $2.2 million, or $0.14 per diluted share, gain net of income taxes was reported on the sale of these assets. Greenspace's operations were seasonal in nature with operating profits in the first and second fiscal quarters followed by operating losses in the third and fourth quarters. Greenspace contributed diluted net earnings per share of $0.01 for the year ended March 31, 2004.

Reconciliation of EBITDA to Operating Earnings

EBITDA is defined as net earnings from continuing operations before minority interest share of earnings, income taxes, interest, depreciation and amortization. The Company uses EBITDA to evaluate operating performance and as a measure for debt covenants with its lenders. EBITDA is an integral part of the Company's planning and reporting systems. Additionally, the Company uses multiples of current and projected EBITDA in conjunction with discounted cash flow models to determine its overall enterprise valuation and to evaluate acquisition targets. The Company believes EBITDA is a reasonable measure of operating performance because of the low capital intensity of its service operations. The Company believes EBITDA is a financial metric used by many investors to compare companies, especially in the services industry, on the basis of operating results and the ability to incur and service debt. EBITDA is not a recognized measure of financial performance under United States or Canadian generally accepted accounting principles (GAAP), and should not be considered as a substitute for operating earnings, net earnings or cash flows from operating activities, as determined in accordance with GAAP. The Company's method of calculating EBITDA may differ from other issuers and accordingly, EBITDA may not be comparable to measures used by other issuers. A reconciliation of EBITDA to operating earnings appears below.

EBITDA	$	18,275	$	15,626
