Trump’s Golden Dome raises major questions: Can it be built? Should it be built? What’s Canada’s role?

U.S. President Donald Trump’s proposed Golden Dome missile defense system has sparked interest from Canada, prompting discussions about the project’s feasibility, cost, and the potential for a space-based arms race. Modeled after Israel’s Iron Dome, the Golden Dome aims to provide more robust protection against missiles fired from other countries and space, combining existing technologies with future developments.

Political science professor Alistair Edgar warns that the deployment of space-based detection and interception systems could lead to an arms race in space, with countries developing their own weapons to counter such defenses. China and Russia have expressed concerns about the Golden Dome proposal, citing offensive implications and the risk of militarizing outer space.

Canadian Prime Minister Mark Carney has confirmed discussions with the U.S. about joining the Golden Dome project, highlighting the serious threat of missile attacks. However, experts question the project’s feasibility, with estimates suggesting a timeline of up to 20 years and costs exceeding $1 trillion.

Former Canadian defense minister Peter MacKay emphasizes the need for bipartisan support and sustained funding across multiple administrations to realize the Golden Dome. Beth Fischer, a U.S. defense policy expert, draws parallels to former President Ronald Reagan’s Strategic Defense Initiative in the 1980s, noting technological challenges and cost concerns.

While the project’s potential benefits for Canada, such as enhanced security and protection of satellites, are recognized, the specifics of Canada’s involvement and financial contributions remain unclear. Fischer cautions that Canada’s role in the project could impact its access to cutting-edge technologies and influence over decision-making.

Ultimately, Canada’s decision to join the Golden Dome project will require careful consideration of the project’s long-term implications and potential economic benefits. As discussions progress, it will be crucial for Canada to assess its role in the initiative and the extent of its technological contributions to ensure a meaningful partnership with the U.S.
