Trump Blames Canada for Wildfire Smoke, Threatens Tariff Hike

other · 2026-07-17

President Donald Trump of the United States attributed the wildfire smoke permeating the country to Canada, announcing plans to incorporate the "incalculable cost" of addressing the pollution into current tariffs on Canadian products. On Thursday and Friday, heavy smoke from numerous Canadian wildfires blanketed parts of the US, stretching from the Midwest to the Northeast, leading to advisories for residents to remain indoors. On Friday, Detroit was reported as the world's most polluted city by IQAir, with Washington and Chicago following closely behind, prompting officials to discourage unnecessary outdoor activities. In New York and nearby New Jersey, where the World Cup final is set for Sunday in an open stadium, air quality was deemed potentially unhealthy for sensitive individuals, an improvement from Thursday's smog that obscured the Manhattan skyline. The National Weather Service cautioned that smoke could intensify overnight into Saturday morning. Andrew Giuliani, executive director of the White House World Cup task force, stated that tournament organizers are "monitoring closely."
