Extreme heat events in Canada refers
Canada has experienced several notable extreme heating events in recent years, many of which have been exacerbated by climate change.[1] These events highlight the increasing frequency and severity of heat waves in Canada, often linked to broader climate change trends.
Significant heat events
[edit]2021 Western North America Heat Wave
[edit]This event is considered the deadliest weather event in Canadian history. From June 25 to July 1, 2021, western Canada, particularly British Columbia, experienced temperatures up to 20°C above normal. In Canada alone, the heat wave affected British Columbia, and in its latter phase, Alberta, Manitoba, the Northwest Territories, Saskatchewan, and Yukon.[2] The village of Lytton, BC, set a new Canadian record high temperature of 49.6°C on June 29, 2021, nearly 24°C higher than normal. This heat wave resulted in over 1,000 heat-related deaths, with 619 confirmed in British Columbia alone. The death toll has been estimated to exceed 1,400 people, with at least 808 deaths estimated in western Canada.[3] The heat dome also led to the destruction of nearly 90% of Lytton by a subsequent wildfire.Cite error: The <ref> tag name cannot be a simple integer (see the help page).Cite error: The <ref> tag name cannot be a simple integer (see the help page).
2023 Heat Waves and Wildfires
[edit]The summer of 2023 saw record-breaking wildfires across Canada, largely fuelled by extreme heat and drought. An early heat wave in May, driven by a strong high-pressure ridge, led to temperatures 5–6 degrees above normal in Alberta, marking the warmest May in 76 years. This early heat wave and subsequent dry conditions pushed the start of the fire season much earlier than usual, resulting in widespread and prolonged wildfires that burned nearly every province and territory. This was the worst wildfire year on record, with fires burning twice the area of the previous worst year and seven times the 10-year average.[4]
2024 Heat Waves
[edit]Various regions across Canada experienced significant heat waves in 2024, all of which were attributed to human-caused climate change.
Alberta
[edit]A heat wave from July 7 to 11 saw temperatures 9.8°C above normal, with a peak daily high of 31.5°C.[5]
Fort Smith, Northwest Territories
[edit]From August 8 to 13, temperatures were 9.2°C above normal, with a peak daily high of 26.9°C.[6][5]
Northern British Columbia
[edit]A heat wave from August 7 to 11 had temperatures 7.0°C above normal, with a peak daily high of 23.6°C.[6][5]were 5.8°C above normal, with a peak daily high of 29.2°C.[6]
Kivalliq
[edit]From August 8 to 14, temperatures were 12.2°C above normal, with a peak daily high of 27.1°C, making this event far more likely due to human influence on the climate.[6]
2018 Montreal Heat Wave
[edit]In the summer of 2018, Montreal experienced a heat wave with temperatures reaching over 40°C with the humidex, resulting in 66 heat-related deaths in the city and a total of 86 deaths across southern Quebec.[7]
