Canadian Prime Minister Mark Carney confirmed on Wednesday that his government is engaged in high-level discussions with the administration of U.S. President Donald Trump regarding participation in the proposed “Golden Dome” missile defense system, a U.S.-led initiative aimed at enhancing North American protection against emerging threats.

Speaking at the conclusion of a two-day Cabinet retreat in Ottawa, Carney said that while no final decision has been made, Canada is actively considering investment and partnership options to join the defense shield, which is intended to counter potential missile attacks from adversaries such as North Korea, China, Russia, and possibly threats “from outer space” in the future.

“We are conscious that we have an ability, if we so choose, to complete the Golden Dome with investments and partnership,” Carney stated. He described the proposal as a strategic military decision that “will be evaluated accordingly,” but declined to disclose the potential financial contribution Canada might make.

The remarks follow Trump’s statement earlier this week, in which he claimed Canada had expressed interest in joining the initiative. Trump also emphasized that any partnership would require Ottawa to pay its “fair share” of the costs—a long-standing theme in his approach to defense alliances.

Carney confirmed that he has spoken directly with Trump about the Golden Dome project and noted that Canadian and U.S. defense officials have been engaged in missile defense discussions for years, although progress has been slow amid political and budgetary challenges.

Highlighting the evolving security landscape, Carney said, “Greater military protection is a good idea,” referencing recent threats and weapons testing by North Korea, escalating tensions with Russia, and rising competition with China. He also hinted at the broader future of defense, mentioning the possibility of missile threats from space-based platforms.

Despite his previously critical stance on Trump, including past remarks accusing the U.S. president of trying to “break” Canada’s international alliances and trade integrity, Carney struck a pragmatic tone on defense cooperation. “We are in a position now where we cooperate when necessary, but not necessarily cooperate,” he said.

Canada’s potential involvement in the Golden Dome system marks a significant shift in its defense posture, signaling a willingness to engage more deeply in North American missile defense after decades of caution and political debate, particularly surrounding participation in the U.S. Ballistic Missile Defense (BMD) program.

Details of the Golden Dome’s architecture, funding model, and timeline have yet to be made public. A formal announcement from the U.S. Department of Defense is expected later this year.
