THUNDER BAY – WEATHER DESK – Northwestern Ontario kicks off 2026 with a strong hold of Arctic chill. Many areas will experience sunshine or clearer skies, but the main concern remains the dangerous wind chills-frequently reaching -30s and even hitting -40s in some parts of the Far North. In various places, Environment Canada warns about frostbite risks, and in the coldest regions, frostbite can happen within just minutes. During these extreme temperatures and wind chill, keeping dogs and cats indoors is the safest option. Limit walks to short and necessary trips (just for bathroom breaks), and opt for sheltered paths away from the wind. Keep an eye out for signs they’re getting too cold: shivering, lifting paws, refusing to walk, whining, hunching down, or trying to turn back. Make sure to wipe off any snow or ice when you come inside, especially between their toes, and check their paws for cracks-ice and road salt can cause burns. If you’re using booties, ensure they fit properly; if not, paw balm can be beneficial. Cats shouldn’t be allowed outside in this weather-create a warm and quiet indoor space away from drafts for them. Livestock will also feel the effects of this cold weather. Take necessary precautions.
