This episode initially aired on June 12, 2025. Following a recent CSIS Americas conference on U.S.-Canada security cooperation, this issue remains an important priority in the bilateral defense relationship.
As a NATO and NORAD member, Canada plays a crucial role in North American continental defense. With the United States now pursuing an expanded continental missile defense posture dubbed the Golden Dome, the Canada-U.S. relationship may be entering a new phase. While the Golden Dome could prove beneficial in advancing Canada’s security strategy, it remains unclear what Canada’s involvement would actually look like, how much protection it would receive under the Golden Dome, and to what extent President Trump’s annexation rhetoric will undermine the Canadian public’s willingness to entertain the missile defense initiative.
In this episode, Christopher Hernandez-Roy sits down with Phillippe Lagassé, Associate Professor with the Norman Paterson School of International Affairs at Carleton University. Together they discuss Canada's historical position on continental missile defense, changes to the threat landscape faced by Canada, and how the government of Prime Minister Mark Carney is approaching defense modernization priorities. They also discuss the effect of ongoing U.S.-Canada tensions on the likelihood that Canada will move forward with participation in the Golden Dome.
