Toronto is currently under a wind chill advisory due to a significant cold front, with temperatures expected to feel as low as -29°C (-20°F). This poses a considerable risk of frostbite and hypothermia, especially for those exposed to the cold for extended periods. The cold front is part of a larger weather system affecting the northeastern United States and parts of Canada, driven by Arctic air masses moving southward. Residents are strongly advised to take precautions to protect themselves from the extreme cold, particularly during nighttime hours when temperatures are expected to be at their lowest.
