Environment Canada has issued an extreme cold warning for the region.
The agency says windchill values closer to -40 are expected, with some relief during the afternoon.
From Environment Canada:
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.
Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.
If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
