LATEST: Ice pellets and freezing rain continue to impact Toronto and GTA

TORONTO - Strong winds, freezing rain and ice pellets have left more than 35-thousand people in southern Ontario without power, Sunday.

The whole region is under weather warnings with Environment Canada issuing a wind warning for the city of Toronto, saying some areas close to the lake could see winds up to 90 kilometres per hour.

Hydro One says it has extra crews working to resolve the power issues but the weather is also causing problems for travellers.

Both provincial police sergeant Kerry Schmidt and Toronto Mayor John Tory requested people stay off the roads whenever possible.

 Tory said that although snowplows and salters were working in the area, slush was being left on most of the roads due to concerns about pushing it off to the side and blocking storm drains. 

Schmidt said more than 150 vehicles had crashed on highways surrounding Toronto by early afternoon Sunday.

Police say drivers who can't avoid going out should be extra careful on the treacherous roads.

Pearson Airport says everyone should check the status of their flights before leaving, with hundreds of trips cancelled due to the storm.

In Toronto, the strong winds have led to a number of fallen tree branches and downed hydro wires. 

As a result, there are scattered pockets of outages throughout the city. 

The Toronto and Region Conservation Authority is also warning that some creeks and rivers could flood by late Sunday due to the heavy rain.
