Prime Minister Mark Carney has rejected Donald Trump’s warning of possible “very serious tariffs” against Europe, saying Canada will determine its own international partnerships as Ottawa pursues a deeper relationship with the European Union.
Carney’s response came after Trump suggested on September 16 that the EU’s proposal to make Canada its first associate member could be considered a “hostile act” toward the United States. Trump said Washington could impose additional tariffs or restrict trade with Europe if he judged the arrangement to be directed against American interests.

Mark Carney says Canada will choose its partners
Speaking at the European Parliament in Strasbourg on September 17, Carney did not name Trump directly. Instead, he argued that Canada and Europe must strengthen their ability to withstand economic pressure, supply-chain disruptions, security threats and coercive trade measures.
“No one can dictate our choices,” Carney said in a speech focused on sovereignty, resilience and democratic cooperation. He described the proposed Canada-EU relationship as an alliance based on what the partners support, rather than a bloc defined by opposition to another country. His address to the European Parliament emphasized that position.
Carney said Canada and the EU are stronger when they combine their respective advantages. He pointed to Canada’s energy resources, critical minerals, financial system, space capabilities, artificial intelligence expertise and defence potential, alongside Europe’s market size, research capacity and industrial base.
The Canadian government has framed the initiative as a broader partnership extending beyond the existing Canada-European Union Comprehensive Economic and Trade Agreement. Proposed areas of cooperation include defence industries, energy security, critical minerals, artificial intelligence, research, financial services and opportunities for young people to live, work and study across the Atlantic. The government’s announcement on the visit outlined the broader effort.
What Trump’s warning means
Trump’s warning adds a new layer of pressure to Canada’s effort to diversify its economic and security relationships. The proposed associate-member status is not the same as full EU membership, and the details of any future arrangement have not yet been established.
The European Commission has described the proposal as part of a stronger partnership with Canada, not an attempt to target Washington. The commission’s announcement came during its September 16 State of the European Union address and was met with applause in the European Parliament.
Carney’s government has nevertheless treated the moment as an opportunity to reduce Canada’s exposure to decisions made in Washington. Ottawa says the EU was Canada’s second-largest trading partner for goods and services in 2025, with two-way trade valued at approximately $178 billion.
The government has also highlighted Canada’s participation in the EU’s Security Action for Europe initiative, which provides opportunities for defence industries and creates a pathway for Canadian companies to take part in European security-related procurement.
Carney and Macron strengthen Atlantic partnership
The Canada-EU message was reinforced on September 20, when Carney met French President Emmanuel Macron in Saint-Pierre-et-Miquelon. The visit marked the first official visit to the archipelago by a Canadian prime minister and placed the two leaders in a French territory just off Newfoundland and Labrador.
Carney and Macron discussed closer cooperation between Canada and France, including an alliance between Canada and the EU designed to strengthen resilience, sovereignty and prosperity. They also directed their space agencies, defence ministries and industries to explore shared infrastructure, including launch systems and ground-control facilities. The meeting with President Macron covered those areas of cooperation.
The meeting carried particular diplomatic weight because it followed Trump’s renewed criticism of Canada’s closer ties with Europe and his repeated pressure on Canada over trade and sovereignty. Neither Carney nor Macron presented the visit as a formal anti-American coalition, but both leaders emphasized the value of stronger cooperation among democratic partners.
What happens next
The next stage will involve determining what associate membership would actually mean. Canada is not seeking full EU membership, and the proposed status would need to be negotiated before any specific commitments could be assessed.
Questions likely to shape the negotiations include whether Canada would receive expanded access to European programs or markets, what regulatory alignment would be required, and how cooperation in defence, energy, technology and mobility would operate.
- Canada and the EU are expected to continue discussions on a deeper political, economic and security partnership.
- Ottawa and European governments will need to define the scope of any associate-member framework.
- Trade negotiations between Canada and the United States remain important despite Ottawa’s diversification strategy.
- Any new U.S. tariffs on Europe could complicate the economic environment for Canadian exporters and European partners.
For Canada, the dispute is no longer limited to a single tariff announcement. Carney’s response signals a wider foreign-policy adjustment in which Ottawa is seeking more options in trade, defence, energy and technology while maintaining negotiations with the United States.
For the moment, the proposed Canada-EU alliance remains a framework rather than a completed agreement. But Carney’s speech, the European Commission’s proposal and his meeting with Macron show that Ottawa is prepared to continue building the relationship despite Trump’s threat of retaliation.
