Ousted Ornge chief executive, Chris Mazza, apparently wants to clarify his involvement in the troubled air ambulance service. Mazza’s lawyer, Roger Yachetti says his client is very interested in setting the record straight. Two warrants from Speaker Dave Levac were issued to compel Mazza to testify before a legislature committee. However, his appearance was put off because two psychiatrists declared him medically unfit to testify. Mazza is expected to appear July 18th before the committee probing the scandal that’s engulfed Ornge.
