Environment Canada has issued extreme cold warnings across Ontario and Quebec as an arctic air mass brings dangerous temperatures to the region. Wind chill values are expected to reach minus 35 to minus 40 degrees Celsius in many areas.

Affected Areas

Toronto, Ottawa, Montreal, and surrounding regions are under the warning. The cold snap is expected to last at least three days, with overnight lows reaching minus 25 degrees Celsius in urban centers and even colder in rural areas.

Health Risks

Health officials are warning residents about the dangers of frostbite and hypothermia. Frostbite can occur within minutes on exposed skin at these temperatures. Vulnerable populations including the elderly, homeless, and those with chronic health conditions face particular risk.

Safety Advisories

Authorities are urging residents to limit outdoor exposure, dress in layers, and check on elderly neighbors. Pets should be kept indoors, and outdoor workers are advised to take frequent warming breaks.

Infrastructure Concerns

Transit agencies report delays due to frozen equipment. Utility companies are preparing for potential power outages as demand for electricity surges. Salt becomes less effective at melting ice below minus 10 degrees, making roads treacherous.

Emergency Shelters

Toronto has opened additional warming centers across the city. Shelters are operating at capacity, and outreach teams are working around the clock to bring vulnerable individuals indoors.

When Will It End

Meteorologists predict a gradual warming trend beginning Thursday, with temperatures returning to seasonal norms by the weekend. Until then, residents are advised to take all necessary precautions against the extreme cold.
