CTV Toronto's Anwar Knight said the GTA can expect a triple whammy of snow, frigid temperatures, and icy conditions.

Knight also warned that the conditions are expected to worsen overnight as temperatures were plunge from around the freezing mark Tuesday night to -7C by the morning.

The long-awaited snowfall resulted in slippery driving conditions across much of the GTA. There were reports of numerous accidents and many cars sliding off the roads especially north of the city.

This included a report of a serious accident in Stouffville, northeast of Toronto, where a multi-vehicle crash was reported in the Highway 48 and 19th Sideroad area. Three people were taken to hospital with serious, but non-life-threatening injuries.

York Regional Police was reported to have closed roads in the area.

Serious injuries were also reported in an accident on Highway 401 at Avenue Road in Toronto.

Meanwhile, the weather also caused numerous cancellations in and out of Toronto's Lester B. Pearson International Airport including a number of flights from Ottawa and Montreal.
