A Cold Warning has been issued by Halton Region Public Health starting January 27, 2026. The Cold Warning is in effect until temperatures rise above -15°C (without wind-chill) or weather conditions improve, and the risks involved with prolonged exposure are reduced.
Exposure to cold weather can increase your risk of cold-related injuries, including frostbite and hypothermia. These injuries can result in severe health consequences.
Anyone can be affected by extreme cold-related weather conditions, depending on length of time of exposure to cold and exertion levels. Those especially at risk include adults over the age of 65, infants and young children, people who have limited resources to house or protect themselves, people who work or exercise outdoors (hikers, skiers). Call or visit family, friends and neighbours who may be more at risk, especially those who live on their own.

Cold and winter weather safety tips
- Plan ahead and check the weather forecast.
- Always wear clothing appropriate for the weather. Cover exposed skin using multiple layers of loose-fitting clothes with a wind-resistant outer layer, a hat, gloves, and scarf.
- Always be on the lookout for signs of frostbite and hypothermia.
- Prepare for winter driving conditions by keeping a Car Survival Kit in your car at all times.
- Where pipes are close to exterior walls or basements or crawl spaces, ensure proper air circulation and adequate heat. Also, make sure your household temperature is not set too low when your house is vacant.
