Pentagon Suspends Participation in Joint Canada-U.S. Defence Board Over Spending Dispute

May 19, 2026

The Pentagon announced on May 18, 2026 that it is suspending participation in the Permanent Joint Board on Defence, an advisory body on North American continental defense established in 1940 by President Franklin D. Roosevelt and Prime Minister William Lyon Mackenzie King. U.S. Undersecretary of War Elbridge Colby cited Canada's failure to make credible progress on defense commitments and implicitly referenced Prime Minister Mark Carney's World Economic Forum statements about forming alliances with countries other than the U.S. The move comes despite Canada hitting NATO's two percent GDP spending benchmark in 2025 with a $9.3-billion defense budget boost, though NATO members have now agreed to reach five percent GDP spending over the next decade. Former Canadian co-chair John McKay warns the decision casts doubt over NORAD renegotiation, Arctic military cooperation, and Canada's purchase of 88 F-35 fighter jets ordered in 2023.
