If you think these last couple of weeks have been brutally hot, it could always be worse! Here is a list of 5 of the most extreme weather conditions ever recorded in Canadian History.
Hottest Day in Canada
July 5, 1937 in Midale and Yellow Grass, Saskatchewan
According to Environment Canada, the hottest day ever recorded in Canada was recorded on that date (during the Great Depression) in Saskatchewan when the mercury rose to 45 C.
The longest and deadliest heatwave occurred from July 5-17, 1936 in Manitoba and Ontario reaching highs of 44 C. The intense heat killed 1180 people during that stretch of time.
Coldest Day in Canada
February 3, 1947 in Snag, Yukon
Temperatures plummeted to -62.8 C in Snag, Yukon — the coldest day in Canadian history. At that temperature, exposed skin would freeze in less than three minutes, drastically increasing the risk for frostbite, hypothermia and death.
