Trump threatens serious tariffs on EU over proposal to make Canada an associate member

WASHINGTON/BRUSSELS — U.S. President Donald Trump has threatened to impose what he called “very serious tariffs” on the European Union, or restrict trade with Europe, if the bloc moves ahead with a proposal to give Canada a new form of “associate member” status.

Trump made the comments on Wednesday, September 16, after European Commission President Ursula von der Leyen proposed opening discussions on making Canada the EU’s first associate member. The proposal comes as Canada seeks to deepen its economic and security relationships with Europe amid increasingly difficult relations with Washington.

Speaking to reporters in Charlotte, North Carolina, Trump said the American response would depend on what he believed the European initiative was intended to achieve.

“If it’s a good intention, that’s fine. If it’s a bad intention, we’ll put very heavy tariffs on Europe,” Trump said, according to Reuters and the Associated Press.

He also said the United States could “stop trading with Europe on many things” if Washington regarded the move as hostile. Trump described the prospect of Canada joining the EU as “laughable” and criticized Canada as a trade partner.

The comments represent another potential flashpoint in relations between Washington and Brussels, with trade already a major source of tension between the United States and several of its traditional allies.

What is the EU proposing?

Von der Leyen made the proposal during her annual State of the European Union address in Strasbourg on Wednesday, with Canadian Prime Minister Mark Carney present.

She said she wanted to work with Canada on opening the door to an associate-membership relationship, alongside deeper cooperation in areas including technology, defence, energy, critical minerals, artificial intelligence, cybersecurity and the Arctic.

The proposed status would be new for the European Union. EU treaties do not currently establish a formal category called “associate membership,” meaning the details of such an arrangement would have to be negotiated and approved.

It is therefore not the same as Canada becoming a full EU member.

The EU and Canada already have a major trade agreement, the Comprehensive Economic and Trade Agreement (CETA), which has substantially reduced tariffs between the two sides.

Carney welcomed the broader direction of the proposal during his visit to the European Parliament on Thursday.

He did not specifically commit Canada to the phrase “associate member,” saying that the substance of any future relationship would matter more than the terminology.

“We do not seek power to dominate others,” Carney told the European Parliament, arguing for greater resilience and protection of Canada’s markets, sovereignty, democracy and rule of law.

Carney also said Canada would determine independently which countries and organizations it chooses to work with.

“No one is going to dictate our culture or with whom we can strike agreements internationally,” he told reporters.

Why Canada is looking toward Europe

Canada’s relationship with the United States has deteriorated significantly under Trump’s presidency.

Washington has imposed tariffs affecting Canadian goods, while Trump has repeatedly spoken about Canada becoming the 51st U.S. state. Ottawa has consequently been seeking ways to diversify its economic relationships and reduce its dependence on the American market.

The United States remains the destination for roughly 70% of Canada’s exports, making the relationship economically critical despite the political tensions.

Closer cooperation with Europe could potentially give Canada additional avenues for trade, investment, defence cooperation and access to strategic supply chains.

Von der Leyen framed the proposed relationship as a partnership intended to strengthen both sides rather than as an alliance directed against the United States.

The proposal is still at an early stage

Despite the political attention surrounding Trump’s response, Canada has not been offered full EU membership, and no final associate-membership agreement currently exists.

The proposed framework would have to be developed and supported by EU member states. The exact rights and obligations associated with any future status also remain to be determined.

European officials have indicated that the initiative could expand cooperation beyond traditional trade arrangements into areas such as defence industries, technology, energy and critical minerals.

Europe responds to Trump’s warning

European officials have pushed back against the suggestion that the Canada initiative is directed against Washington.

European Commission spokesperson Olof Gill said the proposed strengthening of EU-Canada relations was “not against anyone else, but for our common strength.”

France’s Europe minister, Benjamin Haddad, also said the United States does not have the power to determine Europe’s political or geopolitical direction.

The dispute therefore involves more than tariffs. It also raises questions about how Canada and European countries intend to structure their economic and security relationships at a time when traditional alliances are under pressure.

What happens next?

The immediate issue is whether the EU and Canada turn von der Leyen’s proposal into a concrete negotiating framework.

The EU-Canada relationship is expected to receive further attention at a planned Canada-EU summit in Montreal next month. Areas under discussion include trade, defence, technology, energy, critical minerals and Arctic cooperation.

For Washington, the question is whether the proposed European-Canadian relationship will remain a diplomatic and economic initiative or develop into a broader strategic partnership.

For Brussels and Ottawa, the next stage will involve defining exactly what “associate membership” would mean — and whether EU governments are prepared to support it.

For now, Trump’s tariff threat remains conditional. No new U.S. tariff package specifically targeting the EU over the Canada proposal has been announced. The central dispute is still developing as Canada and Europe consider how far they want to take their relationship.
