Police reported several crashes in the Toronto area the morning after a heavy snowstorm passed over the region.

Police from departments across the Greater Toronto Area warned drivers to be cautious and slow. Though snowplows started clearing the white stuff at 8 p.m., and worked through the night, there are still slippery patches on major roadways in and around the city.

Winds of up to 50 km/h are blowing snow across open stretches of highway, leading to reduced visibility and snow drifts.

Ontario Provincial Police reported a fatal crash on the Toronto-bound lanes of the Queen Elizabeth Way at Lyons Creek in Niagara Falls. As a result of the crash, the QEW was closed in both directions near Lyons Road.

In the nearby city of Thorold, a police cruiser spun out on the Highway 58 off-ramp to Highway 406 and ended up in the ditch. The officer was uninjured.

Toronto police said a taxi and a City of Toronto pickup truck collided on Broadview Avenue early Friday morning, just north of Gerrard Street, but no one was injured.

Further north, two cars collided on Highway 400 southbound, between Rutherford Road and Highway 7. Two left lanes were temporarily blocked at approximately 6 a.m. but have since cleared.

Peel, York, Durham and Toronto police have reported dozens of other minor collisions on Twitter Friday morning. OPP have reported morning crashes along Highways 401, 403, 407, 410, 427, 115 and 48, all since midnight.

Flights cancelled into and out of Toronto

Some flights to and from Toronto have been cancelled as a result of the snowstorm.

At Toronto's Pearson International Airport, three departing flights and 14 arriving flights had been cancelled by 7 a.m.

At Billy Bishop Toronto City Airport, five arrivals had been cancelled.

Though most flights have not been effected, passengers have been advised to check in with their airlines before leaving for either airport.
