The man who once oversaw Ontario’s troubled Ornge air ambulance service finally got the green light to appear before a Queen’s Park committee, two months after he was first called to testify.

Dr. Chris Mazza, who was terminated last year without severance, is scheduled to appear before a committee looking into spending irregularities at the air ambulance service this Wednesday at 9 a.m.

He was originally called to testify two months ago, but psychiatrists intervened, arguing that Mazza was mentally unfit to testify.

Mazza has now been declared fit to testify before the committee.

Both Liberal and opposition MPPs will have a chance to grill Mazza.

According to CTV Toronto Queen’s Park reporter Paul Bliss, Mazza will likely be asked questions about his salary not being publicly known, until it was revealed to be $2.6 million per year.

MPPs will also want to know about a mystery $7-million payment to Ornge from an Italian helicopter company for so-called “marketing services.”

That payment is now the subject of an Ontario Provincial Police criminal investigation.
