A man is in critical condition after a rollover in Mississauga Saturday night.

It happened at about 10pm in the eastbound lanes of Highway 403 at Cawthra Road.

A Toyota Corolla veered off the road, struck the steel guardrail, then rolled several times in the centre median before landing on its roof.

The male driver was airlifted to St. Michael’s Hospital in critical condition. The female passenger had non-life-threatening injuries and was taken to Credit Valley Hospital.

OPP investigators believe there might have been a second driver involved in the crash who left the scene.

Witnesses should call police at (905) 278-6131.
