Police are looking for witnesses after a single-vehicle rollover crash on Highway 400 Sunday left a man with life-altering injuries.

Emergency crews were called around 8:30 a.m. to the southbound lanes of Highway 400, about one kilometre south of South Gibson Lake Road in Southern Georgian Bay.

According to investigators, the vehicle was found on its side in the centre median. Police say a lone 30-year-old driver was trapped in the vehicle and was extricated by emergency crews.

He was taken to the local hospital by paramedics before later being transferred to a Toronto-area trauma centre with life-altering injuries.

Police say the crash remains under investigation.

Investigators are asking anyone who witnessed the collision or may have dashcam footage to contact the Southern Georgian Bay OPP at 1-888-310-1122.
