Nuanced futures: Canadian and US defence in the North American Arctic

Canada and the United States have a shared interest in North American defence, and both have committed to spending on Arctic defence capabilities. Defence interactions with China and Russia, and the development of new weapons systems, have put a spotlight on Arctic defence. Much of the resulting activity is preparation for potential, future competition rather than concerns about confrontation in the short term. Nevertheless, preparation discrepancies between Canadian and US approaches to Arctic defence become apparent. In particular, the United States takes a more forward-leaning military approach to Arctic security than does Canada, with a defence-centric military posture. These differences are not insurmountable, and shared understanding of the most significant defence threats related to the North American Arctic, in addition to the long-standing NORAD connection, represent solid foundations. Nevertheless, differences represent areas of friction that could be exploited by adversaries and Canada–US dialogue to minimize the effect of this non-alignment in approaches will be critical.
