Extreme cold warnings in place Monday evening for parts of Ontario, Quebec and New Brunswick
Environment Canada issued extreme cold warnings Monday for northern and eastern Ontario, all of southern Quebec and western New Brunswick.
Residents of southern Ontario could expect the coldest air they have seen in about three winters, CBC meteorologist Colette Kennedy said.
“This cold hasn’t been felt for a while,” Kennedy said, noting that the strong winds were the result of an arctic front coming in from the northwest. “We have had relatively mild winters in many cases, particularly in the east.”
With the wind chill, temperatures could reach -45 ° C in northern Ontario and parts of central Quebec, while temperatures in southern Ontario and western New Brunswick are expected to drop to about -35 ° C, Environment Canada said.
Coldest southern Ontario since before pandemic
In Ottawa, the wind is expected to worsen what is already expected to be the coldest temperatures in the pandemic city, Environment Canada said.
The forecast for the capital calls for a constant drop in temperatures tonight and tonight between -25 C and -32 C as dawn Tuesday. Wind chill could give the impression that -35 ° C.
Environment Canada has said Toronto is expected to drop to -18 ° C tonight.
Kennedy said the last time it was so cold in southern Ontario was before the pandemic began in 2020.
She said such low temperatures mean people should cover as much of the exposed skin as possible, dress in layers – ideally a wind-resistant outer layer – and watch for cold-related health issues such as aches and pains. muscles, numb extremities and shortness of breath.
“Strong winds push any heat your body provides away from you,” Kennedy said. “So that’s another reason people have to be so careful because it can be a very, very short period of time where you might find yourself in a situation of frostbite or worse.”
Montreal shelters are in desperate need of volunteers
In Montreal, temperatures are expected to drop to around -26 C overnight and wind chill values could be as low as -38 C tomorrow morning in Montreal, Laval and the South Shore of Montreal, Environment Canada said.
It hasn’t been that cold in Montreal since January 14, 2018, when temperatures hit -27 ° C, according to the agency.
Meanwhile, local homeless shelters say they are in desperate need of volunteers, with COVID-19 threatening to overwhelm the system as temperatures drop to extremely low levels from Monday evening.
Due to COVID-19 epidemics among people experiencing homelessness in Montreal, there are fewer places available in city shelters and warming centers, said Émilie Fortier, chief of emergency services at the Old Brewery Mission.
Weather could be coldest in two years in the Maritimes
Temperatures will drop to about -30 ° C overnight with a wind chill in most areas of New Brunswick, but could drop to as low as -38 ° C in parts of the western part of the province.
“It looks like it will be one of the coldest air masses we have seen in two years,” CBC meteorologist Ryan Snoddon said. “We have to go back to February 2020 to find such cold temperatures in many places like Halifax, Charlottetown, Moncton and Fredericton.
The coldest air mass to date this season is heading towards the Maritimes today, through Tuesday and Wednesday.
The coldest temperatures will be felt from Tuesday evening through Wednesday morning when we look at lows between -15 and -30 for the most part!

The weather is expected to warm up by Wednesday
Snodden said extreme cold warnings could potentially be issued further east as the arctic air mass moves.
Temperatures are expected to continue to drop over the next two days in the Maritimes and will reach their coldest point late Tuesday evening or early Wednesday morning, he said.
Kennedy and Snoddon both said the cold snap should be over by the end of Wednesday in Ontario, Quebec and the Eastern Townships.
