US Warns Canada on F-35 Deal

The United States has delivered a stern warning to Canada, cautioning that a decision to scrap its planned purchase of F-35 fighter jets could result in “serious consequences.” The warning comes as Canada is conducting a final review of the multi-billion-dollar deal, with a decision expected by September 22. The escalating tensions surrounding the F-35 procurement have strained the relationship between the two long-standing allies and have put a spotlight on the broader implications of Canada’s defense policy.
According to a U.S. government official, the potential “serious consequences” of a Canadian cancellation include a possible threat to the joint U.S.-Canada NORAD (North American Aerospace Defense Command) alliance. U.S. Ambassador to Canada Pete Hoekstra publicly warned that if Canada were to operate a different type of fighter jet from the American fleet, the two countries would no longer have “interchangeability,” a key component of the NORAD agreement. This lack of interoperability, he argued, could fundamentally weaken the binational pact that has been the cornerstone of North American security for decades.
The current review of the F-35 deal was ordered by Canadian Prime Minister Mark Carney in the wake of escalating tensions with the Trump administration. The U.S. has been increasingly hostile toward Canada, imposing tariffs and making public threats, including President Trump’s repeated calls for Canada to become the 51st state. These actions have led some Canadian military and political leaders to question the wisdom of a defense procurement that would make Canada’s air force dependent on the U.S. for software upgrades, spare parts, and other critical operational capabilities. Retired Canadian military leaders have publicly voiced concerns that the U.S. could effectively “brick” Canada’s F-35 fleet if the political relationship deteriorates.
Adding to the complexity, Canada is also considering a separate plan to acquire an alternative fighter jet, the Swedish-made Saab Gripen, which some analysts have argued would be a more affordable and politically independent option. However, the U.S. has also warned against this, arguing that Canada cannot afford to operate two distinct fighter fleets. The concern is that maintaining separate planes would create a logistical nightmare, dramatically increasing the cost of maintenance, training, and spare parts. This opposition from the U.S. puts Canada in a difficult position, forcing it to choose between a politically and economically complex decision to operate two fleets, or to fully commit to one and risk further political fallout.
The F-35 deal itself has been a long and controversial saga in Canada, with a planned purchase first announced in 2010. The current deal, for 88 F-35s, was signed in 2023. But the re-emergence of the political tensions, combined with reports of skyrocketing costs and production delays with the F-35 program itself, has given the Canadian government a reason to reconsider. The impending decision on September 22 will not only determine the future of Canada’s air force but will also be a major test of the country’s sovereignty in the face of immense pressure from its closest ally.
