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.”
