Environment Canada has issued an extreme cold warning this morning for much of the province of Quebec, advising people to bundle up and urging drivers to exercise caution on the roads due to the potential for black ice.
An arctic air mass sweeping across Quebec is causing extreme wind chill of values ranging from -38 to -43 C.
The cold also took its toll on commuters.
CAA-Quebec said there was a three-hour delay for service on the West Island as many drivers struggled to start their cars.
A water main break on St-Antoine and Vinet Streets also snarled traffic headed into downtown.
Extreme cold warnings are issued when very cold temperatures or wind chill create an elevated risk to health, such as frost bite and hypothermia.
It is expected to warm up considerably throughout the day, with the temperature rising to a chilly -11 C by tonight.
