The City of Toronto is under a wind warning ahead of the potential for damaging winds of up to 110 km/h on Sunday.
Environment Canada issued a special weather statement on Friday in anticipation of the weather event beginning Sunday afternoon and through to the evening hours.
On Saturday, the weather agency upgraded the statement to a warning.
The wind gusts will persist as a sharp cold front moves into parts of Southern Ontario. The weather system is expected to weaken on Monday.
Officials say damage to buildings, such as to roof shingles and windows, may occur. There is also the possibility of power outages due to downed electricity lines.
The national weather service said flurries are also in the forecast on Sunday. Local snowfall amounts in the two to five centimetres range are possible by Monday morning.
Road conditions may become treacherous as the strong winds coupled with the snow can create whiteout conditions in localized areas.
