Trump proposes tariff hike on Canada citing wildfire smoke costs
The administration seeks to add 'incalculable' pollution expenses to existing trade duties, drawing sharp contrast with scientific consensus on climate drivers and domestic funding cuts.
US President Donald Trump has threatened to impose additional tariffs on Canadian exports, citing the cost of wildfire smoke affecting North America as a penalty for alleged mismanagement of Canadian forests. The US President accused Prime Minister Mark Carney’s administration of negligence regarding forest maintenance and debris removal, pledging to add these costs to existing tariffs. This action follows a pattern of Trump using tariff threats to pressure Canada on trade practices and border security since returning to the White House in January 2025.
As of Friday, there are 896 active blazes across Canada, with approximately 200 in Ontario. Ontario Premier Doug Ford stated that 81 fires in the province remain out of control. A major conflagration in mid-July in Wabakimi Provincial Park destroyed First Nations communities, leading to the evacuation of 10 communities. Ford thanked US states for support, noting that neighbours have each other’s backs, while Trump and other Republicans criticised Canada’s fire policies.
Trump posted on social media claiming the US is being invaded by unhealthy air and pledged to call Prime Minister Carney. He described the air quality as dangerous and totally unacceptable, accusing the Canadian leader’s government of willful negligence. The US President stated the cost is incalculable and that the expense would be added to existing tariffs against Canadian exports to the US.
US Representative Bill Huizenga joined Trump in criticising Canada’s fire policy, arguing it harms US health and economic prosperity. Huizenga wrote that Canada’s inability to mitigate, contain, and prevent its wildfires must be addressed. The New York Times reported that the Trump administration has slashed funding for wildfire research, including laboratories studying the health effects of wildfire smoke.
Scientists attribute the fires to climate change and drought, contradicting Trump’s claims. The air quality issues have also raised concerns about the viability of hosting the 2026 FIFA World Cup final in New Jersey this weekend, although experts note that weather patterns can change rapidly.
