What began as a far-below-average wildfire season for Canada has since exploded past historical norms, causing national crews to mobilize and United States officials to issue warnings.
Area burned in Canada was less than half of the 10-year average on July 7, but just 10 days and over 300 wildfires later, area burned now sits at 2.78 million hectares (6.87 million acres), according to the National Wildland Fire Summary. The growing total is already 300,000 hectares (741,000 acres) above the 10-year average. The number of fires burning throughout Canada, at 3,656 as of July 17, is already above the 25-year average of 3,652 fires.
The fires have caused widespread hazardous air quality in the U.S. Midwest and Northeast. U.S. President Donald Trump and the Environmental Protection Agency both issued warnings on Friday, urging Canadian officials to “extinguish these fires as fast as possible.”

“We are holding Canada responsible for the fact that they are not properly sainting their forests, and Brush therein, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable,” Trump said in a social media post. “I will call the Prime Minister during the day to find out what they are going to do about it.”
Fire danger is extreme in Ontario, with widespread wildfires causing evacuations in numerous communities across the province, according to Canada’s most recent fire summary. Fires are forecast to continue growing over the coming days due to high temperatures, dry weather and lightning.
The Northwest Territories and parts of Nunavut are also nearing extreme fire danger, while northern Manitoba, north-central Saskatchewan, and interior British Columbia’s fire danger are also expected to increase.
Wildfire smoke impacts are also expected to continue in both eastern Canada and the U.S. over the coming days, specifically due to heavy smoke emitted by fires in western Ontario. Canadian officials said diplomatic engagement is being coordinated to discuss smoke impacts on U.S. states.
