As Trump threatens wildfire smoke tariffs, Canada looks to reduce fire risk
Canadian officials and researchers are addressing the reality of increasingly severe wildfire seasons driven by climate change and fuel buildup. This comes as U.S. President Donald Trump threatens tariffs on Canada, blaming the country for wildfire smoke crossing the border.
Why it matters
The intersection of climate-driven natural disasters and international trade policy highlights the growing geopolitical tensions surrounding environmental impacts.
Over the past week, Trump has criticized Canadian fire management and said the country is "poisoning" U.S. air. He suggested Canada might have to pay .
But experts say Canada's worsening fire seasons reflect a harder reality: not every blaze, or the smoke that comes from it, can be stopped.
"Saying that you would need to extinguish very huge fires like this is similar to trying to stop a hurricane," said Martin Girardin, a forest ecology researcher with Natural Resources Canada's Canadian Forest Service. "It's just unstoppable."
As of Monday, more than 900 fires were burning across Canada and more than 3.7 million hectares had burned in 2026, according to the Canadian Wildland Fire Information System dashboard . Fires have caused extensive damage in Namaygoosisagagun and Whitewater Lake First Nations in northwestern Ontario, and have forced evacuations in many other communities.
