A collision involving as many as 20 vehicles has closed the westbound QEW between the Erin Mills Parkway and Winston Churchill Boulevard in Mississauga, according to the Ontario Provincial Police.
The crash occurred just before noon on Saturday, as southern Ontario experiences its first big winter storm of the season.
If anyone was hurt, their injuries were likely minor, police said.
The vehicles are being taken to an area south of the highway for processing. The OPP said it expects the westbound QEW to re-open within the hour. The eastbound lanes of the QEW remain open.
A police spokesman couldn't give an exact cause of the collision but said drivers were likely not driving in line with weather conditions. Snow is falling and winter storm warnings are in effect for much of the Golden Horseshoe
