TORONTO - Ontario's health minister is looking into executive salaries at the province's air ambulance service after receiving what she calls troubling and concerning information.

Deb Matthews says she's sending a team of forensic auditors to review the financial documents at Ornge to ensure taxpayers get the transparency and accountability they deserve.

The move, she says, comes after she asked the company for information regarding the salaries of Ornge executives.

Matthews also says she spoke with Ontario's auditor general and "he is comfortable with this action."

Once the review is completed, the government will "take any action required" to ensure value for taxpayers.

Ornge says in a statement that it welcomed the minister's decision and has fully complied with her requests.

It also announced today that CEO Christopher Mazza will be on an indefinite medical leave.
