Defence Minister David McGuinty refrained from mentioning the term “Golden Dome,” but his support for a closer partnership with the United States to defend North America against missile threats from hostile states was evident. At a Toronto conference organized by the Eurasia Group and BMO, McGuinty emphasized the ongoing discussions between Canada and the U.S. regarding the necessity of an air defence shield for North America.
While the Liberal government led by Prime Minister Mark Carney has not explicitly committed to joining the missile defence program advocated by President Donald Trump, preparations have been quietly advancing over the past few months. Carney previously acknowledged the talks with the Trump administration about the Golden Dome initiative.
In a recent statement, McGuinty confirmed that Canada is exploring air and missile defence capabilities, lifting restrictions on missile defence activities without much fanfare. This decision aligns with the country’s defense policy update hinting at the exploration of integrated air and missile defence capabilities as part of the NORAD modernization efforts.
Describing the envisioned continental shield, McGuinty explained that discussions with the U.S. are ongoing to establish a system that integrates surveillance from space, air, land, and sea using advanced radar technologies with anti-missile and counter-drone systems like the Patriot system. The primary objective is to detect, track, and neutralize any airborne or missile threats worldwide.
President Trump estimated that Canada’s participation in the program would cost $61 billion US. However, the Canadian government is yet to clarify how this expense would be incorporated into its existing $38-billion contribution to NORAD’s modernization. Critics in the U.S. have suggested that the actual cost of the Golden Dome program could exceed $175 billion US due to the ambitious nature of the project.
It is important to note that the Golden Dome initiative is still in the developmental phase. Analysts argue that Canada’s longstanding involvement in NORAD implies an inevitable role in integrated missile defense with the U.S. NORAD currently possesses the capability to detect certain threats but lacks the mandate and resources to intercept all potential risks, such as cruise missiles.
Canada had previously opted out of the U.S. ballistic missile defence system since 2005, but McGuinty’s recent statement signaled a shift in this stance. Questions remain about the level of defense Canada would receive as part of the Golden Dome program, with research primarily focused on safeguarding the contiguous United States.
A key technical challenge pertains to the extensive geographical coverage required for the Golden Dome system. Unlike Israel’s Iron Dome, which protects a smaller area, the Golden Dome would need to secure vast territories, encompassing millions of square kilometers across the U.S. and Canada.
