Canada's retaliation tests the limit of American power under Trump

Two days prior to the US-Canada trade talks collapsing, Vice-President JD Vance, speaking at a private event, expressed admiration for Prime Minister Mark Carney. According to a leaked audio recording, Vance described Carney as "very sweet," noting that the Canadian leader "comes in and puffs his chest out and says: I'm going to, like, out-tough Donald Trump."

Vance characterized this approach as "hilarious," acknowledging that Canada generally "climbs down" on many issues. While these comments may not have directly triggered Carney's diplomatic withdrawal, they were certainly not helpful. The Prime Minister's decision to walk away abruptly ended trade negotiations and sparked a new round of tariffs between the countries that engage in trade exceeding $872bn annually.

This intensifying rift exemplifies the Trump administration's willingness to employ force globally, whether on friend or foe. However, Trump may have miscalculated in believing Canada would buckle under American pressure, which could have enduring implications for his presidency. The latest dispute represents a continuation of trade tensions that have existed since the first Trump administration and the negotiations that gave rise to the USMCA, which succeeded Nafta.

Personal clashes between Trump and then-Prime Minister Justin Trudeau, who referred to Canada as America's "51st State," fueled geopolitical tensions rooted in the administration's belief in U.S. dominance over its region, including Canada. Administration officials viewed Canada as contributing insufficiently to regional defense while reaping disproportionate economic benefits from trade with the U.S. Consequently, Canada and Mexico, two of America's largest trading partners, became early targets.

Trade Secretary Wilbur Ross once said that Canada's "economic security is national security." As trade negotiations gradually resumed this year, Trump turned his focus away from Canada to intervene militarily in Venezuela and the Middle East. However, the core principle of Trump's international strategy persists: the U.S. is a dominant power that can impose its will for national benefit.

Nevertheless, power has its limits. In both a potential conflict with Iran, targeting U.S. allies and disrupting global commerce, and the current trade dispute with Canada, the U.S. faces a counterpart with the capacity to retaliate, even if its overall power is less. For Canada, the retaliatory tariffs mark an initial step, with future measures potentially including restrictions on U.S. access to Canadian energy and critical minerals, as well as consumer boycotts of American goods.

As the world shifts toward economic security concerns, countries must identify leverage points and chokepoints in supply chains, according to Drew DeLong, head of corporate statecraft at the Kearney Foresight think tank. For now, exit routes remain limited. Trump has escalated his rhetoric, accusing Canada of "ripping off" the U.S., while Ontario Premier Doug Ford retorted by telling the president to "kiss my ass."

Every time the U.S. pushes allies and partners away, it risks incentivizing them to seek new relationships and partnerships rather than complying with U.S. demands. With the retaliatory tariffs set to take effect in two weeks, while the most significant U.S. response - a 50% tariff on Canadian-built vehicles and auto parts - won't kick in until early 2027, negotiators still have a substantial buffer period to resume talks.

However, a multi-month reprieve does not guarantee resolution, as the upcoming November U.S. midterm elections could significantly alter the political landscape. If Democratic congressional victories occur, they might curtail Trump's authority; alternatively, unexpected Republican success could embolden him further. Currently, Ottawa appears to be counting on the former scenario, hoping that fear of a midterm setback in crucial industrial battlegrounds like Michigan and Ohio will compel Trump to retreat before the November vote.
