President Donald Trump is demanding Canada pay up after wildfire smoke choked more than 100 million Americans across 18 states.
In a Truth Social post Friday, Trump accused Canada of “willful negligence” and announced plans to add the pollution costs to existing tariffs on Canadian imports.
“America is being unnecessarily invaded by filthy, polluted, and unhealthy air.”
Trump said he planned to call Canadian Prime Minister Mark Carney later Friday to demand a solution.
“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.”
Nearly 900 wildfires are burning across Canada right now. The smoke has turned skies gray and hazy across the Midwest and Northeast, blurring skylines and forcing outdoor cancellations.
Major League Baseball postponed Friday night’s Cleveland Guardians-Pittsburgh Pirates game after air quality hit the “very unhealthy” category. The smoke has also raised questions about Sunday’s World Cup final in East Rutherford, New Jersey.
“We want to be safe for our players,” Cleveland Guardians manager Stephen Vogt said. “We want to make sure that it’s not too smoky and obviously for the fans as well. It’s just not safe to be out in that environment if it’s not playable.”

The hardest-hit cities include Chicago, Detroit, Minneapolis-St. Paul, and Cleveland. Air quality advisories now cover Washington, D.C., and major population centers across the Great Lakes and Upper Midwest.
As of Friday evening, Prime Minister Carney had not publicly responded to Trump’s tariff threat. Canada is already facing multiple rounds of tariffs from the Trump administration.
Ontario Premier Doug Ford, who has pushed back against Trump’s trade agenda, fired back at the president’s comments.
“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.
Trump’s move signals he’s treating the smoke crisis as a border security and trade issue — not just an environmental problem.
