US President Donald Trump has blamed Canada for wildfire smoke spreading across large parts of the United States, accusing Ottawa of failing to manage its forests and warning that the economic impact of the pollution could be factored into future tariffs on Canadian goods.

In a post on Truth Social, Trump described the smoke drifting into the US as “filthy, polluted, and unhealthy air,” saying millions of Americans were being affected by deteriorating air quality. He added that he planned to discuss the issue with Canadian Prime Minister Mark Carney.

Trump Alleges Forest Mismanagement

Trump claimed Canada had not done enough to maintain its forests and brush, arguing that repeated wildfire seasons have caused significant economic and public health impacts in the United States.

He described the smoke as the result of “willful negligence” and said the financial burden on the US should be reflected in the tariffs already imposed on Canadian products.

Millions Under Air Quality Alerts

Trump’s remarks came as wildfire smoke from Canada triggered air quality alerts across large parts of the Midwest and eastern United States.

Authorities issued warnings covering more than 100 million people across 18 states and Washington, DC, with some regions experiencing air quality levels classified as “very unhealthy” or “hazardous.”

Trade Tensions Continue

The latest comments add another layer to ongoing trade disputes between Washington and Ottawa.

After a recent US Supreme Court ruling limited the administration’s ability to impose tariffs using emergency powers, the White House has explored alternative legal pathways that require investigations and public consultation before introducing new trade duties.

Despite those legal hurdles, the administration has maintained its commitment to pursuing tariff policies aimed at protecting American industries.

Canada Remains in Trump’s Crosshairs

Canada has frequently been criticised by Trump over issues including lumber exports, automobile manufacturing and trade practices.

Although many Canadian goods continue to receive preferential treatment under the United States-Mexico-Canada Agreement (USMCA), uncertainty remains after the administration chose not to renew the agreement in its existing form earlier this month.

The latest dispute over wildfire smoke has further strained relations between the two neighbouring countries as environmental concerns become intertwined with trade negotiations.
