Recent shifts in US defence policy have cast doubt on the reliability of the American nuclear umbrella that Canada and NATO allies have relied on for decades. While European states explore alternative deterrence arrangements through possible nuclear sharing by France and the UK, Canada’s access to these options is limited by its geography. This article argues that Canada can address this vulnerability without compromising its non-proliferation commitments by deepening its role in NORAD. Canada’s strategic importance to North America’s Arctic defence gives Ottawa unique leverage – which it should actively use to reinforce its membership within the American extended nuclear deterrence in face of mounting global security challenges.
