Trump threatens theEuropean Union on Canada and reignites trade tensions with Brussels. Ursula von der Leyen's proposal to open the way for Ottawa to form an association with the EU provoked a reaction from the American president, who called the idea "ridiculous" and warned that, if considered a "hostile act," it could lead to the imposition of "very heavy duties” on European products or even at theinterruption of trade with Europe.
The threat comes as Brussels and Ottawa are working to strengthen a relationship that is already solid economically and increasingly strategically important. Canada, grappling with the trade war with the United States, is seeking new partners, while the EU aims to strengthen its economic and strategic ties amid competition with China and tensions with Washington.

The President of the Commission relaunched the idea in the presence of the Canadian Prime Minister Mark Carney, hypothesizing for Ottawa a role of "first associate member of the European Union”, without achieving full membership.
The rapprochement between the EU and Canada, however, does not arise from a reaction to Trump's policies. Carney himself had already proposed on April 16, 2026, strengthening relations with Europe. Among the common interests identified by von der Leyen were artificial intelligence, climate change, the Arctic, and geopolitics. Furthermore, on the economic front, trade between the EU and Canada has increased by 80% since 2016. Cooperation has also expanded on the security front. In 2026, Canada became the first non-EU country to join the European Safe defense program, adding a strategic dimension to an already growing partnership.
Carney, however, maintained a more cautious stance on von der Leyen's proposed formula, speaking of a closer partnership based on mutual sovereignty and common interests, without explicitly using the term "associate member." The legal status of the proposal also remains to be defined, as this formula is not provided for in the European Treaties.
The story thus adds a further element of tension to the relations between the United States and the European Union already far from relaxed, bringing trade once again to the centre of the conflict.
