Expires: Mon January 26, 2026, 3:38 AM

A prolonged period of very cold wind chills is expected. What: Wind chill values near minus 40. When: Returning tonight into Monday morning for some areas. Additional information: These very cold temperatures are expected to moderate somewhat on Monday, although below normal temperatures are expected for much of the upcoming week. ### Extreme cold puts everyone at risk. Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter. Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm. For more information about the alerting program, please visit: https://www.canada.ca/en/services/environment/weather/severeweather/weather-alerts/colour-coded-alerts.

Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill. Keep emergency supplies in your vehicle such as extra blankets and jumper cables. If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside. Watch for colour changes on fingers and toes, pain, numbness, a tingling sensation, or swelling. If present, move indoors and begin warming. Outdoor workers should take regularly scheduled breaks to warm up.
