TORONTO -- Police are urging drivers to slow down on Sunday night after several crashes were reported as a system bringing heavy snow moves through the GTA.

All eastbound express lanes of Highway 401 at Meadowvale Road are closed due to a crash involving a transport truck and an SUV. It happened around 9 p.m.

Ontario Provincial Police Sgt. Kerry Schmidt said the SUV was trying to exit to the collector lanes when it hit the crashed cushion, lost control, and hit the truck.

The truck then lost control and ended up rolling over, spilling its cargo, Schmidt said.

One person was taken to a hospital with minor injuries.

Schmidt said it would take about six hours before the lanes could reopen.

“Wherever you are, please be careful. Drive safe,” said Schmidt. “If you don’t need to travel, stay at home.”

Around 8 p.m., Peel police were called to the area of Cottrelle Boulevard and Thorndale Road, just east of The Gore Road, after a three-vehicle collision.

Police said a vehicle crashed into a traffic light. Two other vehicles then collided with that vehicle.

No injuries were reported.

“I just want to remind drivers to slow down, take your time,” Const. Sarah Patten said in a Twitter video. “Be aware of your surroundings at all times.
