Trump Threatens Canada With Tariffs Over Wildfire Smoke

July 17, 2026 · USA Today

Smoke from hundreds of Canadian wildfires has been drifting into the U.S., causing dangerous air quality from Minnesota to New York.

President Donald Trump is threatening to add tariffs on products from Canada because of wildfire smoke drifting into the United States. Tariffs are extra charges placed on goods traded between countries. Trump says the smoke is dangerous and that Canada is to blame for not managing its forests properly. He posted his threat on Truth Social on July 17, calling the situation 'totally unacceptable.'

Canada has more than 900 wildfires burning right now, and about 120 of them are out of control. More than a dozen fires are burning near the borders of Washington, Minnesota, Michigan, and Maine. The province of Ontario has been hit very hard, with many families forced to leave their homes. The Canadian government says heavy smoke will likely continue for several more days.

Trump said he would call Canadian Prime Minister Mark Carney to ask what Canada plans to do. He called the problem 'willful negligence,' meaning he believes Canada is ignoring something it could fix. Trump said the cost of the pollution should be added to the tariffs Canada already pays. He claims the smoke has cost the United States billions of dollars.

Prime Minister Carney responded by saying climate change is a shared responsibility. 'Climate change is the responsibility of everyone, including the United States,' he told reporters on July 16. His office did not directly respond to Trump's tariff threat. Carney made his comment after four Republican lawmakers from Michigan wrote him a letter about the smoke.

The Michigan lawmakers said hospitals were treating children, elderly people, and dialysis patients because of the smoke. They called it the third straight year they had to write to Canadian officials about the same crisis. 'We are done accepting apologies in place of action,' the letter said. The lawmakers warned that the U.S. might get directly involved in firefighting across the border if Canada does not act.

U.S. Senator Bernie Moreno of Ohio said he plans to introduce a bill to declare a national emergency over the smoke. The bill could also sanction Canada and revoke visas for some Canadians. Ontario Premier Doug Ford said his province has helped the U.S. fight wildfires before. He asked critics to 'send support, send help' instead of complaining. The Canadian government said it is working with diplomats to discuss the situation with the United States.

"The United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable!"
