U.S. President Donald Trump says the United States will target Canada with new or higher tariffs related to wildfire smoke drifting into the country. Multiple outlets report that Trump makes the threat in a Friday social media post, arguing that Canada is failing to manage its wildfire response. He links the issue to unhealthy air conditions in parts of the United States, citing smoke that affects major cities such as New York and Chicago and prompting air-quality warnings. Several reports say Trump plans to contact Canadian Prime Minister Mark Carney to discuss the smoke and what steps Canada is taking to address it. The Financial Times and Deccan Chronicle describe Trump framing the air as “pollution” and characterize the action as seeking details on Canada’s measures. Other summaries add that Trump ties any potential costs from wildfire smoke to existing tariffs on Canadian goods. While outlets vary in wording—some using stronger language such as “invasion”—they largely agree on the core claim: Trump is threatening tariff increases aimed at Canada because of wildfire smoke affecting U.S. communities.
