Canada’s wildfires raise temperature on Trump-Carney relationship

Wildfires in Canada have sparked a new tension between President Trump and Canadian Prime Minister Mark Carney, as Trump threatens to impose tariffs over the smoke that's drifted into the U.S., calling it a health hazard. This situation underscores the complex dynamics between the two nations, with environmental issues now adding to existing political frictions. The potential tariffs highlight how global environmental crises can impact international trade relations, making this more than just a border issue—it's a significant flashpoint in U.S.-Canada diplomacy.
