Wildfire perimeters for all fire seasons before the current year. Supplied through various sources. Not to be used for legal purposes. These perimeters may be updated periodically during the year. On April 1 of each year the previous year's fire perimeters are merged into this dataset

Wildfire perimeters for the current fire season, including both active and inactive fires, supplied from various sources. The data is refreshed from operational systems every 15 min. These perimeters are rolled over to Historical Fire Polygons on April 1 of each year Wildfire data may not reflect the most current fire situation, and therefore should only be used for reference purposes. Wildfire data is refreshed when practicable and individual fire update frequency will vary. The information is intended for general purposes only and should not be relied on as accurate because fires are dynamic and circumstances may change quickly.

In 2023, more than 17.3 million hectares of land had burned in Canada because of forest fires. This was the largest annual land loss due to wildfires since records started.

In 2022 alone, around 5.2 million hectares of tree cover were lost due to wildfires. A year earlier, wildfire tree cover loss reached the peak of the century so far, with more than seven million hectares. In the past century, Russia has seen the largest annual tree cover loss due to wildfires, with an average of 2.5 million hectares. Canada is the second most impacted country in the world, with an average annual loss of roughly 1.3 million hectares during the same period.
