Donald Trump wants Canada to pay for the wildfire smoke drifting into the United States, and he says the bill should come through tariffs.
The president turned the smoky skies hanging over parts of the U.S. into a trade fight Friday, accusing Canada of sending “filthy, polluted, and unhealthy air” across the border through what he called “willful negligence.”
In Trump’s telling, the smoke was not just drifting south. It was a Canadian cost that should be charged back through tariffs on the country’s imports.
Trump put the blame on Canada’s forest practices, accusing the country of failing to do “basic Forest Management and Debris Removal.”
“I will call the Prime Minister during the day to find out what they are going to do about it. The cost is incalculable! Canada has refused to engage in basic Forest Management and Debris Removal, knowing that such refusal will lead to exactly this result,” Trump wrote on Truth Social.
He then pushed the accusation into tariff territory.
“Canada has refused to engage in basic Forest Management and Debris Removal, knowing that such refusal will lead to exactly this result,” Trump wrote.
“This is Willful Negligence, and becoming a yearly occurrence, costing the United States Billions of Dollars, which cost of this pollution must of necessity be added to the TARIFFS Canada is currently paying.”

The political threat came while the smoke itself was already disrupting daily life for more than 100 million Americans under air quality advisories in 18 states and Washington, D.C.
Across the Midwest and Northeast, social media filled with gray skylines, low visibility and complaints about canceled outdoor plans.
Canada’s own fire count showed how large the crisis had become. As of Friday, the Canadian Interagency Forest Fire Centre listed 897 active fires, with the heaviest activity in Ontario, Quebec and the Northwest Territories, and fewer than 100 under control.
The Great Lakes and Upper Midwest took some of the worst air, with Chicago, Detroit, Minneapolis-St. Paul and Cleveland all affected.
The smoke carries fine particles that can irritate eyes and lungs, trigger coughing and breathing trouble, and aggravate existing health problems.
The Environmental Protection Agency warns that longer exposure can be tied to more severe risks, including heart failure, brain-function impacts and premature death.
AccuWeather warned that wind shifts would keep the smoke moving in waves rather than clearing the region all at once.
“As winds shift, alternating plumes of smoke and cleaner air will move southeastward into the Great Lakes region and the Northeast states through this weekend and into next week,” AccuWeather predicted.
“Shifting winds will bring back thick smoke and poor air quality to New England and New York on Saturday and then likely push it away on Sunday,” the weather website added.
Sen. Bernie Moreno, R-Ohio, backed Trump’s push and framed the smoke as something Americans should be compensated for.
“Americans will not pay the price for the negligence of Canadian leaders. We must create a compensation fund for the victims of this atrocity. Four years in a row of record fires that have produced decades of environmental damage,” Moreno wrote on Truth Social.
He then turned the fire issue into a shot at Canadian liberals.
“Further proof that you don’t have to be very smart to get elected as a liberal, you just have to be woke,” Moreno added.
Moreno had been pushing the issue even before Trump’s post, using smoke-choked Ohio photos Thursday to announce sanctions legislation against Canada and label the situation an “atrocity.”
I’ll be introducing a bill next week to sanction Canada and the responsible Canadian government officials for this atrocity. https://t.co/wFCVwrPdGr

Four Michigan Republicans had already put Prime Minister Mark Carney on notice in a Wednesday letter over Canada’s forest management.
Reps. Jack Bergman, John James, Lisa McClain and John Moolenaar accused the Canadian government of failing to act after earlier assurances that the problem would be treated urgently.
“We were told last year that this would be treated with urgency. It was not,” they wrote.
“We were told the causes, chronic under-investment in forest thinning, fuel reduction, and prescribed burns, along with inadequate enforcement against arson, were being addressed. They were not, or not adequately enough to matter to the people we represent.”
The lawmakers demanded answers on whether Canada had taken measurable steps since last summer.
“What funded, measurable steps has your government taken since last summer to reduce fuel loads and wildfire risk in the provinces responsible for the smoke reaching the American Midwest?” they asked.
“What accountability exists for provincial leaders who treat this as someone else’s problem? And what will genuinely be different by this time next year, rather than another season of statements followed by the same result?”
Carney’s answer was to shift the fight away from forest management and toward climate policy.
“Fighting climate change is the responsibility of all countries, including the United States,” Carney told reporters.
Speaking in French on Thursday, Carney said Canada was still investing in clean energy while the U.S. was moving in the opposite direction.
“Now we’re focusing on investing in clean energy,” Carney said, “in the United States there’s prohibitions now against clean energy — for example, wind energy is one example.”
“Secondly, Canada is maintaining our efforts on the world’s scale and the U.S. is reducing their efforts globally [on climate change], so, yes, climate change is the responsibility of everyone… including the United States.”
His remarks did not connect wind energy to the immediate wildfire smoke hitting the United States.
By Friday evening, Trump’s tariff warning still had no public response from Carney, even as Canada was already under multiple rounds of Trump administration tariffs.
Ontario Premier Doug Ford, who has pushed back against Trump’s trade agenda, answered the criticism by telling U.S. politicians to send help instead of complaints.
“If there’s some politicians out there chirping away, well maybe what you should do rather than complain, is send support, send help, because we have done the exact same thing for our American friends,” Ford said.
