The same storm system that has been affecting eastern Canada will continue to bring stormy weather to Ontario, Quebec and the Atlantic provinces through Friday.
Wind, dropping temperatures and snow squalls will be the main concern, with parts of northern Ontario receiving upwards of 20 cm of snow by the time all is said and done.
On Wednesday, Environment Canada issued winter storm warnings across the region, with the potential for hazardous winter driving conditions.
Strong winds and blowing snow could make for a tricky commute, reducing visibility to as little as 250 metres at time.
The Ontario Provincial Police closed several highways in the Sudbury and North Bay areas Wednesday morning due to freezing rain that contributed to numerous conditions.
The conditions are expected to improve by Thursday evening.
While southern Ontario will avoid the bulk of the snow, flurries will move into the region along with steadily increasing winds throughout the day Thursday.
"The front came through Wednesday night and winds will increase and continue strong through the majority of the day Thursday, with sustained winds of 40 to 60 km/h and gusts of 65 to 80 km/h," says Dayna Vettese, a meteorologist at The Weather Network.
"In the Niagara and Sandbanks regions gusts could could reach 100 km/h."
