Environment Canada has issued a freezing rain warning for Toronto and the GTA.
Snow mixed with ice pellets may accumulate 2cm to 5cm by Sunday morning before changing to freezing rain.
The agency said a brief period of snow could be expected following the freezing rain, but not enough for significant accumulation.
The freezing rain will change to flurries early this afternoon over Southwestern Ontario to Golden Horseshoe later this afternoon or early evening.
Nonetheless, Environment Canada's statement warns of icy conditions outdoors throughout the day, and advises drivers to slow down when on the road in slippery conditions.
Temperatures will be jumping up Sunday morning and hovering around the freezing mark before the freezing rain transitions back into snow on Sunday evening.
They also advised for people to maintain a safe distance when driving and to a lot more time for commutes.
