WHITBY, Ont. - A fourth person has died after a massive car crash on a major highway east of Toronto.
Police say a 10-year-old boy died in hospital Sunday as a result of injuries from a 20-vehicle collision on Highway 401 in Whitby, Ont., on Friday night.
They say a man, woman and another boy died and another four remain in hospital with one in critical condition.
Police say the collision occurred when a transport truck driving westbound crashed into slower moving vehicles approaching a construction site, which caused a chain reaction.
The driver of the truck wasn't injured.
Police say no charges have been laid, but their investigation is ongoing.
