President Donald Trump threatens to impose new tariffs on Canada due to hazardous wildfire smoke and "willful negligence" in forest management.

The administration announced that Canada may face new tariffs to offset the economic costs of hazardous wildfire smoke drifting into the United States. President Donald Trump criticized the northern neighbor for failing to properly maintain its forests and brush, describing the resulting air quality as "filthy, polluted, and unhealthy." The threat follows a period of record-breaking smoke that has blanketed much of the Midwest and Eastern U.S., affecting over 100 million people. While President Donald Trump accused Canada of "willful negligence," Ontario Premier Doug Ford defended the country’s efforts, noting that Canada has frequently provided firefighting support to the U.S. in the past. Canadian Prime Minister Mark Carney acknowledged that climate change is a shared responsibility, while U.S. lawmakers expressed frustration over the recurring smoke, demanding measurable plans for forest thinning and fuel reduction. Despite the current friction, the two nations remain linked by the USMCA trade pact, though the administration recently declined to renew the agreement in its current form.
