Why is the smoke from wildfires in Canada blanketing North America?

In recent years, orange-hued skylines, smoke from wildfires and scorched forests have become commonplace in North America as global warming has contributed to "massive" forest fires. The majority of these fires are located in the north of Canada, home to some if the largest and most intact forests on earth. Canada is experiencing more wildfires than in the past two years. A larger area has burned this year as compared to the 10-year average.

Here are some facts regarding the recent smoke and wildfires.

Why does Canada have so many wildfires?

Canada, which is the second largest country in the world, contains nearly a 10th of all the forest land on the planet and 24% of its boreal forests. Most of these forests are not accessible by road, and many are uninhabited. Forest fires are an important part of nature that helps to eliminate pests and unhealthy shrubbery. In recent years, however, both the size and intensity have increased. Climate change and rising temperatures cause drier forest conditions. Fires spread more quickly in drier forests. Lightning or campfires can start fires in more densely populated areas.

Mike Flannigan is a professor at Thompson Rivers University, British Columbia. He has studied wildland fires. Since the 1970s, the area of land burned in Canada almost quadrupled. He said that warmer temperatures have extended the wildfire season and increased lightning has also caused fires.

What happened this week? Smoke follows the wind as fires grow and forest areas are scorched. The world's poorest air quality was brought to Toronto by fires in northern Ontario, western Ontario and northern Minnesota earlier this week. It then spread to New York City and Washington. Detroit and Chicago had the worst air quality by Friday.

Can the fires be stopped? Some fires cannot be avoided, but governments are working to protect their communities by closing forests to prevent fires caused by humans, using non-flammable materials in high-risk areas and being more prepared.

What has Canada done so far? The federal government has increased funding to fight wildfires. This includes C$316.7 millions ($227million) for aerial firefighting capability over five years, and C$47.8 for Parks Canada National Fire Management Program. Ontario spent C$271 millions on emergency firefighting during 2025-26. This was more than its budget of C$135million. The budget for 2026-2027 is C$150 millions.

WHAT ELSE COULD BE DONE MORE? Experts and politicians started calling for a National Response Organization after Canada's largest wildfire season in 2023 by area burned. These calls increased after fires in the year 2024 destroyed a third of Jasper, a tourist town.

Canada is the only Group of Seven nation without a federal agency dedicated to fighting wildfires. The provinces are responsible for a large part of firefighting.

The Canadian Senate released a report in?June of 2026 that included a call for the creation of a federal coordination office for wildfires, emergency response, and funding for a modern fleet firefighting aircraft.

The report noted that wildfires have become a crisis, citing the area burned in the past few years.

The federal government didn't immediately respond to our request for comment. Canada has approximately 126,000 firefighters working for towns, cities and villages. About 90,000 of these are volunteers. Ken McMullen is the president of the Canadian Association of Fire Chiefs. He said that only 3,000 to 5,000 fire fighters are trained in Canada to fight wildland blazes. McMullen stated that a centralized approach could help coordinate, train and move firefighters and equipment throughout the country when needed.

What are some other areas with wildfires? According to the National Interagency Fire Center, 2026 has been a fire-year above average in the United States, with more than 3.7 million acres burning year-to date, compared to 2.7 million acres on average over ten years. According to the U.S. Drought monitor, fires are burning more intensely and consuming more land in the U.S. West after a record low winter snowpack triggered drought conditions across 90% of the region.

According to NIFC, the United States has seen 40,000 wildfires this year. This is well over its 10-year average, which was around 31,000 at this time. A wildfire that burned an area as large as San Francisco in northeastern Spain forced thousands of people to flee. This summer, there have been nearly 20 reported wildfires in England and Wales. A historic forest near Paris has also burned and turned the skies black. (Reporting from Nivedita Balu, Toronto; additional reporting by Andrew Hay.
