Trump Ties Canadian Wildfire Smoke to Tariffs, Plans a Call With Carney

President Donald Trump accused Canada of failing to address wildfires that have cloaked the U.S. in smoke, saying the costs of the air pollution should be added to the tariffs Canada currently pays and that he would speak with Prime Minister Mark Carney to discuss next steps. EPA head Lee Zeldin cautioned the smoke’s harm to Americans and said the agency is pressing Canada to extinguish the fires, as climate scientists warn that climate change is driving more fires—despite the Trump administration’s recent moves to dismantle wildfire-smoke research labs.
