Exhibit 99.1

LAIDLAW INTERNATIONAL, INC. ANNOUNCES COMMENCEMENT OF TENDER OFFER

NAPERVILLE, Ill., July 10, 2006 — Laidlaw International, Inc. (NYSE:LI) today announced that it is commencing a modified “Dutch Auction” tender offer for up to 15,000,000 shares of its common stock with proceeds from a new $500 million term debt facility. The new debt facility will also be used to make open market stock repurchases after the tender. In the tender offer, shareholders will have the opportunity to tender some or all of their shares at a price not less than $25.50 per share or more than $28.50 per share. The tender offer will expire on August 7, 2006 at 5:00 pm, New York City time, unless extended.

“We set out to achieve a more balanced debt to equity ratio with our balance sheet,” said Kevin Benson, President and Chief Executive Officer of Laidlaw International, Inc. “After a thorough review, we concluded that a leverage ratio of approximately 1.7x EBITDA is appropriate for Laidlaw and is consistent with our overall operating philosophies. The new debt will enable us to execute a sizable stock repurchase plan and return capital to our shareholders.”

Based on the number of shares tendered and the prices specified by the tendering shareholders, Laidlaw International will determine the lowest price per share within the range that will enable it to buy 15,000,000 of its common stock or a lesser amount if fewer than 15,000,000 shares are properly tendered. If more than 15,000,000 shares are tendered at or below the purchase price selected, the Company will purchase shares tendered at prices below or equal to the purchase price on a pro rata basis. In accordance with the rules of the Securities and Exchange Commission, Laidlaw International, Inc. may under certain circumstances and reserves the right to, purchase in the tender offer an additional amount of shares, not to exceed 2% of its outstanding common stock, without amending or extending the tender offer.

All shares that are acquired in the tender offer will be acquired at the same purchase price, including shares that are tendered at a lower price. Shareholders whose shares are purchased in the tender offer will be paid the purchase price in cash, without interest, promptly after the expiration of the tender offer.

Following completion of the tender offer, the Company may also purchase the difference between the aggregate dollar amount that is repurchased through the tender offer and $500 million of its common stock through open market purchases. These open market purchases will not begin until the 11^th business day following the expiration of the tender offer period. Laidlaw International may conduct its share repurchases in the open market, in privately negotiated transactions, through derivative transactions and through purchases made in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934. The repurchase program does not require Laidlaw International to acquire any specific number of shares and may be terminated at any time.

The tender offer is not contingent on any minimum number of shares being tendered. However, the tender offer is subject to a number of other conditions specified in the Offer to Purchase that will be distributed to all Laidlaw International, Inc. shareholders of record.
