Carney Says Ottawa Prepared for Remote Risk of U.S. Military Action
Prime Minister Mark Carney says he has spent the last year preparing for the risk that United States President Donald Trump might order military action against Canada.
The comment came in an interview with The New York Times published September 23, 2026, setting out his view of Canada-U.S. relations. When pressed on Trump's threats to make Canada a 51st state, Carney said he had looked closely at the possibility of a U.S.-led military invasion, according to subsequent reporting on the interview The Globe and Mail.
Carney called the chance an "extreme tail risk," a term planners use for an unlikely event with large consequences. He said it is "not a base case," meaning not the outcome he expects, but that "it would be irresponsible not to" prepare. He declined to discuss what that work involved The New York Times.
The Prime Minister's Office said it had nothing to add to the reported comments, according to deputy communications director Audrey Champoux. The Globe and Mail reported in January, citing senior government sources, that the Canadian Armed Forces had modelled a hypothetical U.S. military invasion of Canada and Canada's potential response.
To put this in context, military staff regularly game out hypothetical threats. That is routine. A prime minister directing planners to treat an attack by an ally as a case to prepare for is not routine. Carney's language holds both ideas together. He places invasion outside the central forecast while confirming deliberate preparation.
Trade rupture
The interview came during a tariff dispute that has defined the bilateral relationship through 2026. Carney imposed retaliatory tariffs, or counter-duties on U.S. goods, in response to a trade war started by Trump, as reported September 9. He said September 8 that he remains resolved to retaliate against U.S. tariffs. A September 7 report said new Canadian levies of up to 50 per cent were expected to begin on a Tuesday.
Washington has kept further escalation on the table. Trump vowed to increase tariffs on all cars, trucks, car parts and steel from Canada to 50 per cent starting on Jan. 1, the Times reported August 26. Last fall, while hosting Carney in Washington, Trump suggested he could make separate deals with Mexico and Canada.
Carney has described the break in structural terms. He said Canada's close ties to the United States were once a strength but have become a weakness, Reuters reported in April.
The broader context here is leverage and audience. A prime minister who speaks publicly about military planning while holding a retaliatory tariff line is signalling to three audiences at once: the White House, Parliament and allied capitals. For Ottawa practitioners, the question is less whether the remote risk happens than how talking about it openly changes bargaining room on tariffs, procurement and continental defence.
Northern posture and alliances
On defence, Carney said Canada would spend 32 billion Canadian dollars to build three military bases in the northern territories, the Times reported in March. The commitment touches Arctic sovereignty, a file where federal jurisdiction overlaps with territorial governments and Indigenous rights holders, and where Quebec, the Prairies, Atlantic Canada and the North read federal announcements through different economic and security lenses.
On alliances, the European Union invited Canada to become its first associate member, according to a September 18 report. Carney also said Canada's support for airstrikes came "with regret" in March, wording that kept allied solidarity while noting distance.
In my view, the sequence is coherent for a government managing alliance risk. Retaliatory tariffs answer immediate economic pressure. Northern basing answers long-term sovereignty and NORAD credibility, NORAD being the joint Canada-U.S. command for North American air defence, without naming the United States as the reason. Outreach to Europe gives Canada more diplomatic options. Public discussion of invasion planning, even as remote risk, reassures Canadians that Ottawa has considered the worst case.
In practical terms, detail remains limited. Carney has not described forces, timelines, legal authorities or federal-provincial coordination for such a contingency, or how Ottawa and the provinces would work together in an emergency. Holding back that detail fits how Ottawa normally handles defence planning. It also limits opposition and provincial scrutiny to the principle of planning rather than the content of plans.
Looking ahead, the next markers are practical. Parliament will want to know how the planning work was tasked, whether it drew on existing defence policy updates or separate direction, and how it relates to the northern basing commitment. Provincial and territorial first ministers will watch for any procurement, infrastructure or emergency-management effects that touch their jurisdiction. Allied governments will read the interview for intent on burden-sharing and alignment.
