Could Canada join AUKUS and operate nuclear submarines?
Short answerIt is possible but would require a major policy shift, more industrial capacity, and a credible plan for crews as well as boats.
NotesCanada's Arctic responsibilities and existing civilian nuclear industry give nuclear submarines a plausible place in the country's defence. Joining AUKUS would nevertheless require a major change in Canadian policy. British, American, and Australian construction capacity was already stretched, so adding Canadian boats would require substantial expansion rather than a simple extra order. The lower-crewed British design approach may suit smaller navies better because American submarines require more personnel. Engineers and sailors can be harder to obtain than money. An actual Russian bomber or submarine intrusion into Canada's northern approaches could also change political willingness quickly. Training the construction workforce would itself be a decade-scale or multi-decade programme.
