NEWTONVILLE, Ont. - A section of a busy Southern Ontario highway has been closed due to a multi-vehicle collision that has resulted in several injuries.
Ontario provincial police say a 10-kilometre stretch of Highway 401 is closed between Newcastle and Newtonville, about 80 kilometres east of Toronto.
Reports say dozens of vehicles were involved, but police say they don't yet have a count as officers are still too busy dealing with the scene.
Paramedics in Kawartha, Ont., report several serious injuries, but say there's more wreckage than injuries.
Firefighters say one driver had to be cut from his rig.
Const. Linda Wolf says police are looking into today's blast of winter weather as a possible factor in the crashes.
Environment Canada had warned of snow squalls off Lake Ontario in the area.
"The weather is not ideal at this point," Wolf said.
