Some areas in Eastern Ontario may experience these wind chills again Friday night into Saturday morning.
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.
Outdoor workers should take regularly scheduled breaks to warm up.
Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
