U.S. suspends joint defense advisory board with Canada

What This is

• The United States has paused its participation in the Permanent Joint Board on Defense with Canada, a long-running bilateral forum on continental defense.
• The Pentagon said the pause is because Canada has not made credible progress on its defense commitments, according to U.S. undersecretary Elbridge Colby.
• The advisory board dates to 1940 and has been used to coordinate and advise on shared North American defense, including work connected to NORAD.

Why This Matters

• It tests how resilient Canada–U.S. defense cooperation is when broader political and economic relations deteriorate.
• It can reduce the two governments’ ability to align priorities and coordinate long-term planning for shared air and maritime security.
• It raises the practical stakes of defense spending debates by linking them to access and influence in joint decision-making.
• It signals to allies and adversaries how unified North American security policy appears during periods of bilateral friction.
