What Caused The Fires In Canada June 2024. Canada's 2023 wildfire season was the most destructive ever recorded, with 6,551 fires scorching nearly 71,000. The first foreign firefighters to reach quebec amid canada’s worst wildfire season on record said that some of the blazes were 100 times bigger than any they had ever seen.
But in 2023, 59 per cent of the fires were caused by lightning, resulting in 93 per cent of the total area burned. In canada, more than 25 million acres of land — an area larger than portugal — has burned, and the fire season shows no signs of slowing.
