Trump blames Canada for wildfire smoke and threatens new tariffsthreatens new tariffs

US President Donald Trump blamed Canada for wildfire smoke choking northern US cities and announced he would add pollution costs to existing tariffs on Canadian imports.

The air quality worsened in New York, Detroit, and Chicago, with some areas seeing the worst air globally as the smoke worsened health risks for sensitive groups before the World Cup final.

This move matters as it escalates US-Canada trade tensions and could reshape tariff policies ahead of major international sporting events in the region.
