Canada’s Arctic defense strategy strengthens surveillance from sky to sea

Earlier this week, Prime Minister Mark Carney announced that Canada would deepen defense cooperation with Nordic partners and take a more active role in Arctic and North Atlantic security. The announcement matters because the Arctic is becoming a more contested and more consequential part of North American defense. 

The Arctic has long been central to continental defense, but the character of the threats moving through it is changing. During the Cold War, it was the most direct avenue for Soviet bombers and missiles approaching the continent. Cruise missiles and hypersonic weapons still matter, but they are no longer the whole story.

Undersea data cables now run across northern waters. Energy installations, satellite ground stations and sensor networks are spreading into high latitudes. Interfering with those systems — often quietly, below the threshold of open conflict — has become part of the strategic toolkit of modern strategic competition. 

That shift is forcing policymakers to rethink what defending the northern approaches actually entails. During the Cold War the problem was straightforward: detect bombers or missiles crossing the polar approaches and respond. Today the challenge is less tidy. Surveillance must extend across immense maritime spaces. Critical infrastructure has to be watched. Hybrid threats — probing operations, interference with sensors, tampering with undersea cables — have to be detected before they become something worse. 

Ottawa has begun adjusting. Canada has committed significant funding to northern defense infrastructure: upgraded Arctic airfields, logistics hubs, expanded surveillance networks and improved access for military operations across the North. The goal is simple enough, at least on paper. Canada wants to operate more consistently........
