Donald Trump posted on Truth Social on July 17 threatening to slap new tariffs on Canadian imports over wildfire smoke drifting across the border. His reasoning: Canada’s “willful negligence” in managing its forests is costing the US billions of dollars in economic damage, and someone needs to pay for it.
What actually happened
Approximately 950 wildfires are currently burning across Canada, sending thick plumes of smoke into the US Midwest, the Northeast, and major population centers including New York and Chicago. Health advisories have been issued across multiple regions as air quality deteriorates to hazardous levels.
Trump described the recurring smoke as an “unnecessary invasion” and estimated the resulting economic losses in the billions. He indicated plans to discuss the matter directly with Canadian Prime Minister Mark Carney, framing the conversation as part of broader tensions between the two countries on environmental and trade issues.
The Canadian response was swift and blunt. Ontario’s Premier called Trump’s comments “unacceptable.”
