Canadian Prime Minister Mark Carney on Thursday embraced the prospect of his country becoming the European Union’s first associate member, saying closer ties with the continent would ensure no country could control Canada’s markets or undermine its sovereignty.

Carney’s speech to the European Parliament repeatedly extolled cooperation between Europe and Canada — but the relationship with the U.S., which has defined Canada’s economy for decades and has increasingly soured, hung over the address.

Trump’s tariffs, demands for economic concessions, and repeated talk of making Canada the 51st state have pushed Ottawa to reduce its dependence on its neighbor and seek a far deeper economic, security and political relationship with Europe.

Carney told the parliament that he welcomed European Commission President Ursula von der Leyen’s proposal, unveiled Wednesday, though he acknowledged that “associate membership” remains to be defined.

He outlined what he was proposing: deeper integration across trade, defense, critical minerals, artificial intelligence, energy, space, research and financial services to make both sides less vulnerable to economic and geopolitical pressure. He later told reporters he was not pursuing full membership of the EU.

“We do not seek power to dominate others,” he said. “On the contrary, we are pursuing resilience so that no one can control our open markets, impair our sovereignty, threaten our territorial integrity, or undermine our freedoms, our democracies, our rule of law.”

The prime minister received an ebullient welcome when he walked into the chamber in Strasbourg, France — with many lawmakers approaching him to shake his hand and ask for selfies — and a standing ovation after he spoke. One parliamentarian had donned a Canadian hockey jersey.
