Trump threatens new tariffs on Canada as wildfire smoke blankets US cities
President Donald Trump said the United States will add pollution costs to tariffs on Canada as smoke from wildfires spreads unhealthy air across New York, Chicago and Detroit. The haze has also raised concerns for the World Cup final in New Jersey this weekend.

Smoke from wildfires burning across Canada has drifted deep into the United States, triggering air quality alerts in New York, Chicago, Detroit and other major cities. Health officials urged residents in affected areas to limit time outdoors as pollution levels climbed to unhealthy thresholds.
President Donald Trump said Friday that the United States would factor the cost of the pollution into tariffs on Canadian goods, blaming Ottawa for failing to contain the fires. He did not specify how the additional costs would be calculated or when they might take effect.
World Cup organizers said they are monitoring the smoke ahead of Sunday's final in New Jersey, and have not ruled out adjusting match conditions if air quality worsens. Canadian authorities have not yet responded publicly to Trump's tariff threat.
