​The freezing rain left streets under a layer of ice this morning and prompted the closure of many schools. It also caused traffic accidents, transit and flight delays, and some power outages outside of Toronto.

Toronto's Pearson International Airport urged travellers to check flight information with airlines before heading to the airport. 

Shabeen Hanifa, spokeswoman for the Greater Toronto Airports Authority, said more than 110 flights scheduled to leave from Pearson were cancelled as of 6 p.m.

"It's pretty good right now. Safety is the number 1 priority for us and it's definitely winter operations," she said. 

Hanifa said winter operations means the airport is focused on removing snow from the airfield and clearing ice off aircraft.

Environment Canada meteorologist Geoff Coulson  said driving conditions in Toronto could continue to be tricky this evening.

"The best advice is to take it easy out there. The secondary roads could be problematic. There could be some slippery sections in and around the GTA during the evening commute," he said.

'Icy, slippery and hazardous'

Coulson said freezing rain in March is not that unusual.

"This is something we can see from time to time," Coulson said. "We can get these early spring storms that can be quite potent."

He said the warmer weather earlier in March made this weather event stand out, but it's not a surprise, given the calendar. He said snow tires would have come in handy this morning. 

The freezing rain delayed many GO buses, while ice on overhead power lines delayed some TTC streetcars this morning.

Salting is complete on arterial roads and expressways, the city said in a tweet. It is continuing on collector and local roads. 

Schools in the Dufferin-Peel Catholic School Board and the Peel School Board were closed Thursday.

York University cancelled classes at its Keele and Glendon campuses, while the University of Toronto's Mississauga campus and Humber, Sheridan and Centennial Colleges were also closed.

Environment Canada has warned that surfaces such as highways, roads, walkways and parking lots could be "icy, slippery and hazardous."

It said periods of freezing rain are expected to continue until early Thursday evening before changing to rain as temperatures rise.

More accumulation of ice in Toronto is possible, it said. 

Earlier this morning, the freezing rain caused major power outages outside the city.

As of 6 p.m., Hydro One crews were responding to 208 incidents affecting 20,025 customers. 

While the freezing rain is expected to lift in the GTA later tonight, the warning is expected to remain in place this evening for much of southern Ontario.
