A series of dangerous snow squalls are expected to sweep over parts of the province this Friday.
Travel warnings have been issued in areas such as Orillia, Perth and Waterloo.
"Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility in some locations," reads a statement from Environment Canada.
Grey-Bruce and Huron-Perth will see the most accumulation.
However, the GTA is still expected to get hit with a few flakes.
Temperatures will drop today, with the coldest air of the season hitting Ontario this weekend.
The city of Toronto is expected to dip as low as -10°C on Saturday evening.
