Environment Canada says the vast majority of Ontario is under prolonged extreme cold warnings, with wind chill values in many areas hovering around -40 in many areas.
The weather agency has issued extreme cold warnings for areas around Lake Huron and Georgian Bay stretching to the north.
Communities around Lake Huron and Georgian Bay will see cold weather continue into Wednesday, where areas on the shore of Lake Superior are expected to see frigid temperatures cease on Tuesday.
Currently, there are no watches or warnings in Toronto or across the GTHA as some of the coldest temperatures seen in recent years are set to descend upon the region over the next several days with wind chills between -20 and -25. The intense cold is not expected to ease until Wednesday.
The weather agency has also issued a snow squall warning watch for Northern Huron County and surrounding areas, which is expected to bring 30 to 60 centimetres of snow until Wednesday.
The agency says extremely cold temperatures put everyone at risk and frostbite can develop within minutes on exposed skin, especially with the wind chill.
