President Trump has threatened very serious tariffs on Europe or a suspension of trade if Canada becomes an associate member of the European Union, a proposal advanced by European Commission President Ursula Von der Leyen. The initiative remains undefined, while Canadian Prime Minister Mark Carney has said Canada wants closer trade and defense integration with the bloc rather than full EU membership. The dispute comes amid tit-for-tat tariffs, strained political ties and Canada’s broader effort to diversify its partnerships. Trump and Carney are both due at next week’s United Nations General Assembly, but no meeting is currently scheduled. The wider agenda includes a lawsuit alleging that Anthropic, OpenAI, SpaceXAI and Google colluded to slow artificial-intelligence development, as well as Trump’s weekend stay at Camp David.
