Few people expected a US president’s annexation jokes to reshape a Canadian election. But that’s exactly what happened in 2025 when Donald Trump’s tariff threats and “51st state” talk turned the race upside down. Mark Carney’s Liberal Party won the April 28 vote, and the outcome had less to do with domestic policy than with a surge of nationalism sparked from the south.

Did Trump endorse Pierre Poilievre?

What was Trump’s public stance on Poilievre?

  • Trump did not explicitly endorse Poilievre. In fact, Trump’s social media posts during the campaign focused on tariffs and the “51st state” concept, not on individual Canadian candidates (Reuters (global news agency)).
  • Poilievre, who had previously drawn parallels between his populist style and Trump’s, avoided associating with the US president once the tariff threats escalated (CBC News (Canadian public broadcaster)).

Did Poilievre seek Trump’s endorsement?

There is no public evidence that Poilievre actively sought Trump’s endorsement. Conservative strategists feared that any visible link to Trump would alienate moderate voters, especially after Trump’s trade war started hurting Canadian industries (The Globe and Mail (national Canadian newspaper)).

Bottom line: Trump never endorsed Poilievre. The Conservative leader tried to distance himself from Trump’s policies after realizing they were a liability with Canadian voters.
The paradox

Trump, who often praises populist conservatives abroad, inadvertently hurt the Canadian Conservatives by making nationalism a polarizing issue tied to US aggression.

Why did the Conservatives lose in Canada?

How did Trump’s annexation talk affect Conservative support?

  • In November 2024, the Conservatives held a strong lead in national polls (CBC News (Canadian public broadcaster)).
  • After Trump’s tariff announcement in January 2025 and his repeated references to making Canada the “51st state,” Conservative support began to erode. By March 2025, the Liberals had overtaken them (Reuters (global news agency)).

What role did tariffs play?

The tariffs were seen as an existential threat to Canadian manufacturing and agriculture. Voters punished the Conservatives for not being perceived as strong enough defenders of Canadian sovereignty against Trump’s pressure (The Globe and Mail (national Canadian newspaper)).

Bottom line: The Conservative lead evaporated because Trump’s trade war turned “Canada First” rhetoric into a liability. Voters wanted a leader who would stand up to Washington, not one who shared its populist playbook.

“Trump pushed the Conservative Party down the political stairs.”

— The Atlantic (editorial magazine), April 2025

Why this matters

The Conservatives lost not because of policy failure, but because an external actor shifted the national mood. This is rare in Canadian politics and signals a new vulnerability for parties seen as too close to US populism.

Did Trump endorse Mark Carney?

Did Trump express support for Carney?

Trump never endorsed Carney. In fact, Trump’s rhetoric was hostile toward Canada’s leadership generally. But Carney, a former central banker who had criticized Trump’s policies in the past, became the unintended beneficiary of Trump’s attacks (Reuters (global news agency)).

Did Trump congratulate Carney?

As of May 2025, there is no public record of Trump congratulating Carney. The US president made no direct statement about Carney’s victory (Reuters (global news agency)).

“Trump made Carney’s turnaround victory possible.”

— BBC (UK public service broadcaster), analysis

Bottom line: Trump did not endorse Carney, but his trade war and annexation comments united Canadian voters behind the Liberal leader as a symbol of resistance.

What did Trump tweet about the Canadian election?

What were Trump’s key tweets?

  • Trump posted repeatedly about Canada being the “51st state” and threatened high tariffs on Canadian goods (Reuters (global news agency)).
  • He did not specifically mention the election or any candidate by name.

How did Canadians react?

Trump’s tweets were widely shared in Canadian media and social feeds. Nationalist sentiment surged, with many voters saying they felt their sovereignty was under attack. The Liberal Party’s campaign used Trump’s remarks in ads warning that only the Liberals could push back (CBC News (Canadian public broadcaster)).

Bottom line: Trump’s tweets backfired spectacularly. Instead of weakening Canada’s resolve, they galvanized 7 million advance voters—a record—and boosted Liberal turnout.
What to watch

Future US campaigns may think twice before targeting Canadian sovereignty, because the 2025 election showed that external threats unify Canadian voters faster than domestic issues can divide them.

How are Carney and Trump connected today?

What is the current state of US-Canada relations under Carney?

Carney was sworn in as prime minister on March 14, 2025, after winning the Liberal leadership (Government of Canada (official federal website)). He immediately took a tough line on trade, calling Trump’s tariffs unjustified and vowing to diversify Canada’s export markets (Prime Minister of Canada (executive office)).

How does Carney plan to deal with Trump?

  • Carney has proposed retaliatory tariffs and accelerated the Trans-Pacific Partnership talks with Asia-Pacific nations.
  • He acknowledges that Trump’s actions inadvertently helped him win, but he refuses to credit Trump directly (Reuters (global news agency)).
Bottom line: Carney owes his job in part to Trump, but the two are now adversaries on trade. For Carney, the challenge is to convert campaign nationalism into durable economic policy.

Frequently asked questions

As of late April 2025, there is no public record of Trump congratulating Carney.

What was the voter turnout in the 2025 Canadian election?

Reportedly 69.5% of eligible voters cast ballots, the highest since 1993 (Wikipedia (user-edited encyclopedia)).

How did Canadian media cover Trump’s involvement?

Canadian outlets extensively covered Trump’s tweets and tariff threats, often framing them as attacks on Canadian sovereignty (CBC News (Canadian public broadcaster)).

What are the implications for US-Canada relations?

Carney’s tough trade stance suggests a rocky period ahead, though both countries have strong incentives to negotiate.

Did the Conservative party blame Trump for their loss?

Privately, some strategists pointed to Trump’s rhetoric as the main factor that eroded their lead (The Globe and Mail (national Canadian newspaper)).

How did other world leaders react to the Canadian election?

Many European allies expressed relief, viewing Carney as a more predictable partner than a Conservative government aligned with US populism.

The 2025 Canadian election was a case study in how an outsider’s words can reshape a nation’s vote. For Mark Carney, the victory came with a double-edged mandate: stand up to Trump’s pressure while navigating a minority parliament. For the Conservatives, the lesson is harsh—ties to US populism, even perceived ones, can cost you an election you once had locked up. For Canada’s voters, the implication is clear: national identity can override partisan loyalty when an external threat feels real.
