One person was rushed to a trauma centre in serious condition after a two-vehicle collision in Whitchurch-Stouffville early Thursday morning.

It happened at around 4:15 a.m. on Bloomington Road, between Warden Avenue and Kennedy Road.

York Regional Police say the driver of a Toyota Rav 4 was heading eastbound on Bloomington Road when he crossed the centre line and struck a westbound dump truck.

The truck driver, police say, managed to avoid a head-on collision and side-swiped the Toyota into the ditch.

The driver of the Toyota, identified as a 27-year-old man from Thornhill, was rushed to hospital with serious injuries and is currently in stable condition.

The driver of the truck was not injured.

Bloomington Road was closed on Thursday morning as police investigated the crash.

It is not clear what caused the driver of the Toyota to cross the centre line but police say there is no indication that he was impaired.

Police are asking anyone who witnessed the collision to come forward and speak to investigators.
