Arctic Blast Grips Canada: Polar Vortex Brings -55°C Wind Chills, Flight Chaos

A powerful polar vortex has descended upon Canada, plunging most of the country into a deep freeze with dangerously low temperatures and wind chills reaching as frigid as -55°C. This extreme weather event, expected to persist throughout the weekend, has triggered widespread travel disruptions and prompted urgent safety warnings from authorities across multiple provinces.

Nationwide Travel Disruptions and Airline Alerts

The severe cold snap is causing significant operational challenges at airports nationwide. Air Canada has reported delays at key hubs including Toronto Pearson International Airport and Montréal–Trudeau International Airport due to the extreme conditions. The airline is advising passengers with flexible travel plans to consider changing their flights at no additional cost.

WestJet has issued comprehensive travel advisories affecting multiple Canadian airports in Toronto, Montreal, Halifax, and Moncton, along with several U.S. airports in Atlanta, Houston, and New York. Both airlines strongly recommend that travelers verify their flight status directly before heading to airports.

Toronto Pearson Airport officials have echoed this advice, urging all passengers with scheduled flights to confirm their travel arrangements with their respective airlines prior to departure. The airport authority emphasized that proactive checking could prevent unnecessary trips to the terminal during this period of heightened disruption.

Regional Weather Impacts and Emergency Responses

Environment Canada has issued severe weather warnings across multiple regions, with the most extreme conditions affecting the Prairie provinces. Saskatchewan, Manitoba, and parts of Northwestern Ontario are experiencing the coldest temperatures, with wind chill values ranging from -40°C to -55°C prompting orange alert warnings from meteorological authorities.

In response to the dangerous conditions, several municipalities have implemented emergency measures:

  • Regina and parts of Manitoba closed schools and cancelled bus services and field trips on Friday
  • Regina officials deployed an overnight warming bus circulating between shelters until Monday
  • Eastern Alberta faces persistent wind chill values of -40°C to -45°C throughout the weekend
  • Most of Ontario east of Thunder Bay and Southern Quebec are experiencing wind chills from -30°C to -45°C

The City of Toronto has activated additional support services, keeping warming centres open and providing temporary shelter spaces. Street outreach teams are conducting wellness checks to encourage vulnerable individuals to seek indoor shelter, while distribution of cold-weather supplies to unhoused populations continues.

Additional Weather Challenges and Infrastructure Concerns

Beyond the extreme cold, forecasters predict additional weather complications. Southwestern Ontario and parts of the Greater Toronto Area are bracing for a major snowstorm on Sunday, with accumulations expected to reach 15 to 30 centimetres accompanied by blowing snow that could further complicate travel and infrastructure.

The Atlantic provinces are facing dual challenges from the cold weather. Newfoundland and Labrador Hydro and Nova Scotia Power have issued power conservation warnings, urging customers to reduce electricity usage where possible to prevent overloading provincial power grids during this period of peak demand.

This Canadian cold snap coincides with significant winter weather disruptions south of the border, where more than 12,000 flights have been cancelled across the United States due to a sweeping winter storm system. The continental scale of this weather event underscores the severity of the atmospheric conditions affecting North America.

Local officials across Canada continue to urge residents to take necessary precautions, including limiting outdoor exposure, dressing in layers, and checking on vulnerable community members. The combination of extreme cold, potential snowfall, and travel disruptions creates a complex weather scenario requiring careful planning and heightened awareness throughout the affected regions.
