A man has been airlifted to a trauma centre in Toronto after a crash on County Road 27 in Springwater Township last night.
He had to be extricated from his vehicle, and he remains in critical condition.
Police tell CTV News Barrie that a northbound vehicle crossed the centre line and hit a car travelling in the opposite direction.
The driver of a pick-up truck also swerved to avoid the crash, and ended up in the ditch.
County Road 27 remained closed until around 2 a.m. Sunday morning. Plows were called in to clear snow that accumulated on the road during the almost eight-hour closure.
The OPP is investigating the crash.
Sergeant Peter Leon says road conditions and weather are likely factors.
