U.S. Trade Friction Hits Midterm Wallets as Canada Disputes Meddling Claims

American voters in border states are weighing tariff costs against foreign policy disputes as the November 3 midterms approach. The U.S. Embassy in Ottawa released a fact sheet on Wednesday listing Canadian actions it claims amount to potential interference in the U.S. election cycle. Prime Minister Mark Carney rejected the allegations on Friday, stating there is no merit to the claims.

The diplomatic friction intensified in early 2025. Trump officials warned Canada to stay out of the midterms. In response, the U.S. Embassy cited specific instances, including Liberal MP Anthony Housefather canvassing for a Florida Democrat and comments by Industry Minister Mélanie Joly on counter-tariffs. The list also included an Ontario government Ronald Reagan ad and a federal billboard campaign from early 2025.

While Washington accuses Ottawa of meddling, President Donald Trump has endorsed foreign candidates since returning to the White House. He has backed candidates in Poland, Honduras, Colombia, and Japan. Most recently, he voiced support for Israeli Prime Minister Benjamin Netanyahu ahead of his election. He also supported Viktor Orbán’s failed re-election bid in Hungary, with Vice-President JD Vance attending a rally in Budapest.

In Argentina, Trump suggested a financial support package would depend on the results for President Javier Milei’s party. During the 2025 Canadian campaign, he wrote on social media that he would rather deal with a liberal than a conservative. Former U.S. Ambassador to Canada James Blanchard said the current administration has no credibility in making such accusations. He noted that previous administrations would have taken the charge more seriously.

The U.S. Embassy declined to comment when asked if a similar endorsement from a Canadian official would constitute interference. The trade war has become a key issue for Republican candidates in Michigan and Maine. Senator Susan Collins said she secured exemptions to the levies. She stated she will continue working with administration officials to encourage a broader trade agreement with Canada.

Republican candidate Mike Rogers released an ad criticizing the tariffs. He said Canada is not an enemy and urged an end to the tariff war. The U.S. Treasury Secretary Scott Bessent called Alberta a natural partner for the U.S. during a discussion on a separation referendum. Reports indicate Republican operatives helped the separatist campaign in Alberta earlier this year.

Daniel Drezner, a professor of international politics at Tufts University, described the situation as the pot calling the kettle black. He said the administration has a long track record of intervening in the elections of official allies. He noted that heads of state typically avoid overt campaigning for foreign parties to maintain business relationships with either outcome.

Carney expressed disappointment that the U.S. envoy sees it as his role to make such suggestions. He said he does not see the administration blaming Canada for poor midterm results and imposing more tariffs. Joly pushed back on the accusations, noting she has met with both Republicans and Democrats. The embassy’s fact sheet followed warnings from Ambassador Pete Hoekstra and Trump adviser Peter Navarro.
