The most unsettling part of the latest Canada–U.S. defence dispute was not a new weapon or military deployment. It was a question about whether a longstanding ally could always rely on American protection.
In an interview released October 11, 2026, U.S. Ambassador to Canada Pete Hoekstra cautioned against assuming that American defence support would continue indefinitely, pointing to NATO commitments and the need for allies to carry their share of responsibility. He also ruled out an American invasion of Canada.
The comments arrived as Ottawa was increasing military spending, modernizing Arctic surveillance and managing growing tensions with Washington over trade and military procurement. They did not change NATO’s collective-defence treaty or end the countries’ joint air-defence operations. But they exposed an uncomfortable question at the centre of North American security: how much can Canada depend on a partner whose expectations are changing?
Hoekstra’s Interview Put an Old Defence Assumption Under Scrutiny
During an interview with Jim Csek and Iain Burns on The Really Big Show, Hoekstra was asked whether Canada could count on the United States to defend it indefinitely. His answer began: “Always is a long time.” He linked continued defence cooperation to allies fulfilling NATO commitments. The exchange arrived amid a difficult period in Canada–U.S. diplomacy.
The ambassador also said the Canada–U.S. relationship had “fundamentally changed.” Yet the interview contained an important reassurance: when the conversation turned to the possibility of an American invasion, Hoekstra rejected that scenario. Those questions should not be confused. He did not announce the withdrawal of American forces, declare Canada an adversary, or unveil a new treaty policy. His comments instead reveal how Washington’s demands for military burden-sharing have entered a bilateral relationship traditionally understood as exceptionally close. For Canadians accustomed to continental defence cooperation, even rhetorical uncertainty can be unsettling.
NATO’s Article 5 Remains a Real Treaty Obligation
Canada and the United States helped found NATO in 1949. Article 5 establishes the alliance’s collective-defence principle. An armed attack against one member in Europe or North America is treated as an attack against all. Each ally is obligated to assist, but the treaty leaves countries discretion to determine which measures are necessary. That assistance can include armed force, yet specific American troop deployments are not guaranteed.
This legal distinction is vital to understanding Hoekstra’s warning. A diplomat’s remarks cannot, by themselves, erase an existing treaty obligation, and NATO has not announced that Canada has lost Article 5 protection. At its July 2026 summit in Ankara, the alliance again reaffirmed collective defence and its shared security commitments. Article 5 was invoked only once, after the September 11, 2001 attacks on the United States. That history recalls how America’s allies stood behind the United States when collective defence was needed most.
NATO’s Five-Percent Goal Has Raised the Stakes
NATO’s latest investment commitment is far more demanding. At the 2025 summit in The Hague, allies agreed to aim for annual defence and security-related spending equal to five percent of gross domestic product by 2035. The pledge separates that total into at least 3.5 percent for core military requirements and up to 1.5 percent for infrastructure, cybersecurity and defence industries. Members must submit spending plans.
That timeline matters because a pledge for 2035 is not a requirement to spend five percent today. NATO leaders reaffirmed collective defence in July 2026 and urged members to turn budgets into capabilities and operational readiness. American officials have presented the spending push as an attempt to distribute responsibilities more evenly. Secretary of State Marco Rubio made a similar argument in Portugal on October 8, saying Washington’s pressure on allies was intended to strengthen deterrence rather than express hostility. The issue extends beyond spending percentages.
Canada Has Met Two Percent, but the New Target Is Far Higher
Canada’s latest spending figures challenge the familiar claim that Ottawa still falls short of NATO’s earlier benchmark. The Department of National Defence says the country met the two-percent-of-GDP target in the 2025–26 fiscal year, spending approximately C$63.45 billion on eligible defence expenditures across multiple federal departments. The government called it a major attempt to address longstanding shortfalls in equipment, recruitment and military readiness.
The spending included C$2.1 billion for a substantial pay increase for Canadian Armed Forces members, while Ottawa also announced a C$1.4-billion investment in domestic ammunition production. The investments aim to retain personnel, restore supplies and maintain equipment. However, reaching two percent does not mean Canada has fulfilled the much larger 2035 pledge. The planned five-percent total includes both core defence and broader security-related expenditures. Hoekstra’s message therefore arrives during a major transition, as Ottawa emphasizes its significant progress and Washington demands more.
Washington Previously Paused a Historic Bilateral Defence Forum
Hoekstra’s remarks did not emerge in isolation. In May 2026, U.S. Undersecretary of Defense for Policy Elbridge Colby announced that Washington was pausing the Permanent Joint Board on Defense, a bilateral military advisory forum established in 1940. Colby accused Canada of insufficient progress on its defence commitments. That followed Canada’s achievement of the two-percent spending benchmark.
Canada’s Defence Minister David McGuinty responded by emphasizing the countries’ long history of cooperation and pointing to investments in radar, aircraft and other continental defence capabilities. Security specialists also noted that the board helps American planning. The pause did not amount to the closure of NORAD or the cancellation of the NATO treaty, but it showed that disagreements had moved beyond public speeches into institutional arrangements. The announcement drew criticism in Canada. The board had helped coordinate defence policy for decades. A wartime institution had become a new diplomatic pressure point.
NORAD Is a Two-Way Security Partnership, Not a Favour
NATO is only part of the picture. Canada and the United States operate the North American Aerospace Defense Command, known as NORAD, a binational organization founded in 1958. Its responsibilities include aerospace warning, aerospace control and maritime warning. Radar installations, satellites, fighter aircraft and command centres help both countries detect and respond to threats approaching North America. The commander answers to the Canadian prime minister as well as the American president.
This structure makes continental defence a shared interest, not simply protection purchased by one country from the other. Canada’s northern airspace helps identify threats approaching American territory. Canadian fighter crews also remain on alert as part of the surveillance and response network. Each government contributes personnel, resources and capabilities. NORAD also coordinates the tracking and possible interception of unidentified aircraft threatening either country’s airspace, in peacetime as well as emergencies. NORAD’s operations explain why abrupt changes would complicate continental security.
Ottawa Is Spending Billions to Strengthen Arctic Warning Systems
Canada is pursuing a C$38.6-billion, 20-year NORAD modernization plan, announced in 2022. It aims to improve surveillance, communications and infrastructure. A key project is Arctic Over-the-Horizon Radar, designed to identify aircraft and other potential dangers at much greater distances than conventional ground-based radar can normally observe.
In June 2026, Canada signed arrangements with Australia to acquire radar technology for the northern-approaches system. Government documents value the broader Arctic radar program at more than C$6 billion, with initial capability anticipated in December 2029. Although the project’s name evokes installations in the Far North, its first selected transmit and receive sites are in southern Ontario. By refracting radar signals through the ionosphere, the technology can detect objects beyond Earth’s curvature. The project illustrates how long new capabilities take to deliver. New systems can strengthen Canadian independence while simultaneously improving the common continental warning network.
The F-35 Decision Has Become a Diplomatic Flashpoint
Fighter aircraft remain contentious. Canada announced plans in 2023 to acquire 88 American-made F-35 jets to replace its aging CF-18 fleet. The overall project budget is approximately C$27.7 billion, including infrastructure and support. Prime Minister Mark Carney ordered a review of the purchase in March 2025, and official defence briefings in May 2026 said a decision about the wider acquisition was still pending.
Hoekstra has publicly warned that choosing not to proceed with the full F-35 purchase could affect the way the two countries organize joint air defence. His concern involves interoperability: fighter jets operating together must share information, training methods and compatible systems. Canada’s initial commitments have continued, with early deliveries intended for pilot training in Arizona. The choice also involves Canadian industrial benefits and long-term maintenance costs. Ottawa must balance military needs, taxpayer value and supply dependence. That makes fighter procurement a broader diplomatic question.
Canadian Service Members Have Already Made Major Allied Contributions
Spending debates often overlook military service. More than 40,000 Canadian Armed Forces personnel served during Canada’s Afghanistan mission between 2001 and 2014. Government records confirm that 158 Canadian service members died. Many others returned with lasting injuries. Canada’s involvement followed the attacks on the United States and reflected the countries’ longstanding commitment to common security.
Canada’s contributions continue. Under Operation REASSURANCE, approximately 2,000 Canadian military personnel serve in Latvia, where Canada leads a multinational NATO brigade on NATO’s eastern flank. At the July 2026 NATO summit, Ottawa announced that the operation would continue through 2031 and that Canada would assume a larger leadership role in Multinational Division North. Those deployments require long absences, demanding training and sacrifices from military families, particularly spouses and children. Equipment and readiness concerns remain legitimate. They do, however, complicate any suggestion that the country contributes nothing to the security arrangements from which it benefits.
Trade Disputes Have Made Defence Trust Harder to Separate
Hoekstra’s interview also addressed tariffs, stalled commercial negotiations, border security and competition with China. His remarks reflected tensions beyond defence spending. On October 8, U.S. Trade Representative Jamieson Greer said Washington was maintaining its current negotiating position toward Canada, although communication between officials continued. Trade and defence involve different agreements but overlapping political leadership.
The connection is especially sensitive because Canadian and American industries are deeply involved in each other’s defence supply chains. Canadian firms supply several multinational aerospace programs and specialized military equipment. Official figures show more than 110 Canadian companies have received F-35 production contracts, demonstrating the considerable financial and industrial stakes involved. Negotiating fighter purchases, industrial benefits or security cooperation becomes harder when governments are also debating tariffs and broader economic independence. Still, it would be misleading to conclude that a trade dispute automatically suspends NATO obligations. The concern is eroding trust despite enduring legal commitments.
The Real Test Is Whether Canada’s Plans Become Working Capabilities
For Ottawa, Hoekstra’s warning highlights a challenge larger than one budget. Canada’s 2026 Defence Industrial Strategy calls for greater domestic production, faster procurement and less vulnerability to foreign supply disruptions. Its ten-year goals include creating 125,000 jobs and increasing Canadian defence exports by 50 percent. These are targets, not completed achievements, and meeting them requires consistent investment for years.
Washington also has powerful reasons to preserve cooperation. NORAD protects airspace on both sides of the border, NATO’s collective defence remains in force and Canada’s Arctic matters to continental security. The central question is not whether the ambassador has cancelled America’s security obligations; he has not. It is whether both governments can maintain the political confidence needed to make those obligations credible during a period of rapid change. For Canadian military personnel, businesses supplying defence equipment and communities near critical facilities, success will depend on working capabilities and durable partnerships.
