Frigid start to March as wicked wind chills blast Ontario and Quebec
Bundle up! Some wicked wind chills make a return to Ontario and Quebec as we kick off March this weekend
While the calendar inches closer to spring, an Arctic front is set to bring a return of frigid temperatures and wind chills to Ontario and Quebec this weekend.
The Arctic air, driven by a lobe of the polar vortex, will cause a sharp temperature drop across the region.

Saturday will begin with the mildest conditions of the weekend, but temperatures will rapidly decline as the Arctic front passes and bitter northwesterly winds take hold. By Saturday evening, temperatures will plummet well below freezing and continue falling into Sunday.
Toronto will see temperatures drop from -6°C on Saturday evening to -18°C by Sunday evening, potentially marking the city’s coldest March temperature since 2015 (-18.9°C).
Wind chill values in Toronto could dip to -25.
Meanwhile, Ottawa and Montreal may experience overnight lows of -20°C Sunday, with wind chills between -25 and -30.
