The debate surrounding a new American missile defense system, dubbed „Golden Dome,” has brought into sharp focus not only the United States’ military ambitions but also its complex relationship with its closest ally, Canada. President Donald Trump’s declaration that Ottawa was interested in participating in this strategic effort opened a Pandora’s box, raising fundamental questions about sovereignty, costs, and the future of decades-long military cooperation.
Trump’s Promise and the Price of Participation
Formally announcing the creation of the „Golden Dome,” President Trump made a notable claim: Canada had already asked to take part in the effort. „They want to hook in, and they want to see if they can be a part of it,” Trump said of America’s northern neighbor in May, adding, „It won’t be very difficult to do. They’ll pay their fair share.” However, relations between Washington and Ottawa have been rocky for almost the entirety of Trump’s second term, fueled by his repeated statements that he wants Canada to become the 51st state. These tensions quickly manifested in the context of „Golden Dome” when Trump demanded Canada pay $61 billion to participate. The issue resurfaced recently, with the American leader criticizing Ottawa for allegedly opposing the use of Greenland as part of „Golden Dome.”
Canada’s Dilemma: Strategic Interest or Subservience?
Despite these frictions, Canada remains interested in taking part, at least in theory, Canadian Prime Minister Mark Carney told an audience in Montreal. „The project is under development and, if it serves Canada’s interests — and I think there are certainly many scenarios where that would be the case — we will be willing participants,” Carney underscored. This stance raises a crucial question: if Canada were to participate in „Golden Dome,” what would its role be? And, perhaps more importantly, if the U.S. were not to involve Canada in „Golden Dome,” could its existing missile defense architecture, anchored around cooperation through NORAD, survive?
A spokesperson with Canada’s Department of National Defence/Canadian Armed Forces recently stated that „those [Golden Dome] conversations are ongoing, and we will only participate if it is right for both parties.” The U.S. Department of Defense, for its part, did not respond to questions about how it is currently factoring Canada into ongoing „Golden Dome” planning or the status of talks.
The NORAD Pillar: A History of Cooperation at Risk?
At the core of missile defense between the two countries is the North American Aerospace Defense Command (NORAD), created in 1958. Its primary mission is detecting and tracking ballistic missiles, and potentially intercepting cruise missiles, that are targeted at either nation’s homeland. The organization is headed by a U.S. four-star general, who is dual-hatted as the NORTHCOM commander, while a Canadian three-star general acts as the deputy. The future of NORAD, as well as its role in „Golden Dome,” remains somewhat murky. While it seems logical that „Golden Dome” would fall under NORAD, no such public declaration has been made, and the project’s details remain closely guarded.
Single Command or Dual Personality?
Glen VanHerck, a retired U.S. four-star general and former head of US Northern Command and NORAD, explained the complexity of the command structure. In the event of a missile launch from North Korea towards North America, the U.S. general would first assume their NORAD commander hat to track and warn of the incoming threat. „NORAD has to make an assessment in minutes. Is the missile a threat to North America? Is it a threat to the President’s location, the Prime Minister?” VanHerck emphasized. „If it is a threat to North America, and if it’s going to be engaged, then I would have to change hats and put on my NORTHCOM hat and engage the threat with my… NORTHCOM authorities.” This duality of responsibilities highlights the tight interconnectedness, but also the challenges, of integrated defense.
What Ottawa Can Offer: Terrain, Technology, and Investment
VanHerck pointed to a number of benefits and avenues for collaboration that Canada can offer. „The biggest thing they offer is terrain… [and] a larger footprint forward to place, sensors, radars and effectors,” he said. „There’s a reason President Trump sees Greenland as a strategic location, and I would say the same can be said for Canada and Alaska. The shortest route to North America is over the poles and up through the Arctic, and that doesn’t matter whether you’re coming from Russia or China or North Korea. It’s all the same way.” Ottawa has already started investing in a range of capabilities that could potentially contribute to the „Golden Dome” by expanding tracking and targeting capabilities.
Beyond Missiles: An Integrated Response to Diverse Threats
„Golden Dome is much more than space-based interceptors and ballistic missile threats. It’s cruise missiles. It’s hypersonics which come from maritime platforms parked off the coast,” VanHerck added. „And so there are ways that Canada can be very helpful with Golden Dome, and more broadly, just continental defense for North America.” Front and center are Canada’s plans to invest $28.3 billion USD to help modernize NORAD over the next two decades. That plan includes multiple Arctic Over-the-Horizon Radar (A-OTHR) sites in Ontario, planned to come online in 2029, to help with early warning radar coverage and threat tracking. Beyond the A-OTHRs, VanHerck pointed towards the 16 Boeing P-8A Poseidon aircraft Ottawa is planning to buy to replace its aging CP-140 Aurora fleet, as well as the potential to buy new submarines for enhanced maritime awareness.
Tom Karako, a missile defense expert with the Center for Strategic and International Studies, added two more weapons to that list of possible contributions to „Golden Dome” – the acquisition of Lockheed Martin’s F-35 Lightning II fighter jets for tracking and targeting threats, and the Canadian Surface Combatant (CSC) program with SPY-7 Radars.
Canada’s Conditions: Fair Partnership or Dependence?
There could also be future Canadian defense investments folded into „Golden Dome,” said Eric Sauve, a consultant for the Canadian Department of National Defence, though he cited internal concerns about Washington simply tasking Ottawa with purchasing U.S. tech. „If it’s going to be a joint partnership Canada should provide part of the technology as well, not just be told at the end, ‘Here’s the percentage of the Golden Dome you are going to finance, and it’s going to be 99 percent US industry,'” Sauve said.
Canada’s US Ambassador Kirsten Hillman recently stated that the country is „deeply committed to arctic defense” with current systems and future capabilities like A-OTHRs. „Much as we do across all sorts of defense systems, where we’re interoperable, we work together,” Hillman said while speaking more broadly about a possible collaboration on „Golden Dome.” „We make our investments that make sense for Canada in defending our territory and defending our sovereignty, but we work with the Americans and other allies to maximize the benefits of those.” A Canadian defense spokesperson added that „in this rapidly evolving strategic environment, Canada recognizes that Integrated Air and Missile Defence (IAMD) is critical to deter and defend against the full spectrum of air and missile weapons.”
Erosion of Trust: Threats to Sovereignty
These investments are likely to continue whether Canada takes a formal role in „Golden Dome” or not, according to Karako, as NORAD remains a useful construct for both sides. Sauve agreed, stating that even if Ottawa were a hard no on „Golden Dome” participation – something he doesn’t anticipate – NORAD would survive. „The relationship between Canada-US and NORAD is very, very strong, we’re fully integrated,” he said. „I think [Golden Dome] is kind of treated as an aside thing, not part of a NORAD commitment.”
However, Sauve warned: „But, there is a lot of trust that has gone down the gutter between Canada and the US. When you mentioned the 51st state threats of invasion, talking about our prime minister as a governor of a state, it had a massive effect on the trust issue between our two countries… Can we trust the US again? We feel like we’ve been betrayed.” This lack of trust, generated by political rhetoric, could represent the greatest obstacle to Canada’s unreserved integration into the American vision of continental defense.
