A handful of communities north of Toronto are waking up to a blanket of wet and heavy lake-effect snow.
The communities include Barrie and Collingwood, where about two to four centimeters were expected as a system moved in from Lake Huron.
Environment Canada is urging motorists to be cautious because they may encounter slick driving conditions and poor visibility.
The snow may not stick around for long because the region is expecting a daytime high of 5 C.
Flurries were possible in Toronto on Friday morning, followed by isolated showers in the afternoon.
Meanwhile, a special weather statement remains in effect for Dufferin, Innisfil, Barrie, Orillia, Midland, Huron, Perth, Mount Forest, Arthur, northern Wellington County, Grey and Bruce because of lake-effect snow.
Because of "relatively warm ground temperatures," local snowfall amounts will be no greater than five cm in those areas, Environment Canada said.
