Donald Trump accused Canada of neglecting wildfire management, causing toxic smoke to cover many areas in the U.S., and threatened to charge damages from the pollution as part of tariff measures on Canadian imports before scheduling talks with the Canadian Prime Minister.
On 18 July 2026, foreign news agencies reported that U.S. President Donald Trump sharply criticized Canada after smoke from wildfires spreading across many parts of Canada drifted over several U.S. states, prompting air quality warnings ahead of the 2026 FIFA World Cup final to be held near New York City.
Trump posted on the Truth Social platform that the U.S. is being unnecessarily invaded by dirty, toxic, and harmful air, accusing Canada of failing to properly manage forests and brushland, allowing wildfires to spread and affect its neighboring country.
The U.S. leader said he would call Canadian Prime Minister Mark Carney to demand explanations for what he called "deliberate negligence," threatening that the costs of air pollution damage should be included as additional expenses in U.S. tariffs imposed on Canadian imports.
Meanwhile, hundreds of wildfires continue to burn across Canada, causing smoke to blanket large parts of North America. On the same day, major U.S. cities including Detroit, Chicago, Washington D.C., and New York ranked among the worst in the world for air quality.
Ontario Premier Doug Ford responded to U.S. political criticism by saying that instead of complaining, the U.S. should send personnel and resources to help control the wildfires.
The White House revealed that officials are holding informal talks with FIFA and related agencies to assess the impact of smoke on the 2026 FIFA World Cup final scheduled for Sunday near New York City.
