The city of Toronto, for example, could break a multi-year record. Arctic air mass caused the mercury to hit -19C on Friday morning, with a wind chill of -30C, according to Environment Canada.
As the Toronto Star reports, this is the coldest temperature the city has seen since 2019. On a January day that year it was -22.6 °C.
Greater Toronto’s polar vortex this weekend prompted Environment Canada to issue an extreme temperature alert for the weekend.
There is also a risk of frostbite in the Queen City.
In addition to Ontario and Quebec, the Maritimes will also be badly hit by the cold spell this weekend.
