Forecasters say today's back-to-school commute is likely to be hampered by snow across southern Ontario.
Environment Canada says snow is expected to blanket all of southern Ontario from west to east overnight making untreated roads slippery for the morning commute.
The agency says the Greater Toronto Area could see 5-8 cm of snow by the time the snowfall winds down Monday afternoon. There could be 2-4 cm on the ground by 7 a.m. An earlier threat of freezing rain has subsided.
Snowfall warnings have been issued for areas to the east and northeast of Lake Huron and Georgian Bay, where up to 15 centimetres of snow is expected overnight, with another five centimetres falling by mid-morning.
In the north, snow squalls from Lake Superior are expected to bring up to 15 centimetres of snow to the Sault Ste. Marie and Wawa areas.
A weather advisory for the Sudbury, Kirkland Lake, Manitoulin and North Bay areas warns snowfall totals off Lake Huron may reach 20 centimetres and could affect Highway 17 and Highway 69.
