The first day of winter in Toronto brought more snow to a city still reeling from Friday's major storm.

Between five and 10 centimetres fell Sunday morning but blowing winds created white-out conditions throughout the afternoon.

The storm system is now making its way eastward.

At Pearson International Airport, dozens of flights were delayed on Sunday morning -- though the runways had mostly been cleared by the afternoon.

Hundreds of city plows and salt trucks spent the day on the roads making streets safer for commuters but police still had to deal with a number of accidents.

According to the Ontario Provincial Police, the morning snowfall caused more than 100 minor collisions north of the Toronto area between 6 a.m. and 9 a.m. Sunday.

It takes about 20 hours for city crews to clean 5,600 kilometres of roadway and 6,000 kilometres of sidewalk. The back-to-back storms meant the city's 600 ploughs and 200 salt trucks have been on the road since Friday, clearing about 40 centimetres of snow that fell throughout the weekend.

"Today we managed to go through all our interior road ways and express ways," said Myles Currie, manager of Toronto's road operations. "It will be past midnight before we are done with all our side streets."

CAA flooded with calls

Despite the city's hard work, the weather has left thousands of motorists stranded.

According to spokesperson Edyta Zdancewicz, the CAA in southcentral Ontario has received more than 12,000 calls for help since the first system hit on Friday.

"We are definitely seeing anyone who does go out in this weather getting themselves into a little bit of trouble," Zdancewicz said Sunday during an interview with CTV Newsnet.

At the peak of Friday's storm, drivers had to wait an average of two hours for assistance from the CAA, which asked some drivers to call back if the situation wasn't an emergency.

"If you've got weather like this, winter tires are definitely something you should have on your vehicle," Zdancewicz said. "If you have only performance tires, it may be better to stay at home in this type of weather and wait until everything gets plowed."

At Pearson International Airport, dozens of flights were delayed on Sunday morning -- though the runways had mostly been cleared by the afternoon.

Environment Canada senior climatologist David Phillips told CTV Newsnet that "it looks like a very good chance" it will be a white Christmas for all parts of Canada for the first time since 1971.
