Tensions rise as US imposes tariffs on Canada and threatens the EU over potential associate membership

The United States escalated a trade conflict with Canada on September 15, 2026, by imposing a 50% import tariff on various Canadian goods, including steel, paper products, fur, and certain cheeses. This move followed retaliatory tariffs previously enacted by Ottawa. Furthermore, the U.S. government announced a total import ban on specific Canadian items, such as motorcycles over 800cc and certain dairy products, effective September 29.

Simultaneously, U.S. President Donald Trump has threatened to impose severe tariffs or terminate trade with the European Union in response to a proposal by European Commission President Ursula von der Leyen. The proposal suggests making Canada the first "associate member" of the EU and potentially including the country in a future European Security Council. Trump labeled the initiative "ridiculous" and a potential hostile act, while EU officials, including spokesperson Olof Gill, clarified that the partnership is intended for mutual strength rather than against any third party.

Canadian Prime Minister Mark Carney welcomed the EU proposal during an address to the European Parliament in Strasbourg, emphasizing the need for deeper strategic cooperation in defense, energy, and technology. As the EU evaluates the logistical implementation of an associate membership—a status not currently defined in its treaties—the international trade climate remains highly volatile.
