Canada's Prime Minister, Mark Carney, has announced that Canada will deepen defense cooperation with Nordic partners and take a more active role in Arctic and North Atlantic security. This comes as the Arctic becomes a more contested and more consequential part of North American defense. The changes in the nature of threats moving through the Arctic have led policymakers to rethink their strategy. Canada has invested significant funding to northern defense infrastructure, including upgraded Arctic airfields, logistics hubs, expanded surveillance networks and improved access for military operations across the North. The move is seen as a significant step forward in Washington, where the United States is investing in modernizing NORAD. If Canada's Arctic investments prove to be successful, they could strengthen North American defence in practical ways.
