Ontario Provincial Police say a three-vehicle crash on Highway 401 in Whitby has seriously injured one person.
Sgt. Kerry Schmidt said the crash happened at around 6:30 a.m. Thursday and all westbound lanes were closed approaching Brock for Ornge air ambulance to pick up a patient.
One person suffered critical injuries due to the crash, Schmidt said. The driver of the vehicle was extricated.
Ornge said they airlifted a man in his 30s to a Toronto hospital.
“My understanding is all three vehicles were in the left-most lane of the 401 westbound,” Schmidt said. “Traffic slowed suddenly and the white pick up was the last car in line it was struck from behind by a blue Chevrolet and the red vehicle was the last vehicle in and collided into the back of the Chevrolet.”
Schmidt said the major collision reconstruction team was piecing together what exactly happened.
The highway reopened at around 10:30 a.m. following the investigation and cleanup.
