A man has been taken to hospital with serious injuries following a collision on Highway 401 in North York.

It happened in the westbound collector lanes of the highway after Dufferin Street.

Ontario Provincial Police said a transport truck collided with a sedan. Images from the scene showed the severely damaged sedan lying on its roof.

Toronto Paramedic Services said they transported a man believed to be in his 50s – the driver of the sedan – to a trauma centre with serious, but non-life-threatening injuries.  

The cause of the collision is not yet clear.

All westbound collector lanes of Highway 401 are closed between Avenue Road and Keele Street because of the collision, OPP say.
