===Life extension and replacement===
Under the [[Justin Trudeau]] government's defence policy paper, ''Strong Secure Engaged'' (2017), the operational life of each ''Victoria''-class boat was to be extended by one additional "life-cycle" (or by about eight years).<ref>{{cite web |url=https://www.canada.ca/en/department-national-defence/corporate/policies-standards/canada-defence-policy.html |title=Strong Secure Engaged |publisher=Government of Canada |date=6 August 2020 |access-date=11 August 2020}}</ref> This was designed to permit the operation of the fleet into about the early to mid-2030s. As of 2020 no decision had been taken on the actual replacement of Canada's submarines which were then already thirty years old. Analysis by the Naval Association of Canada indicated that the lead times, technical challenges and costs involved in submarine replacement would be significant were such a program to be initiated.<ref>{{cite web |url=https://www.navalassoc.ca/wp-content/uploads/2019/07/Niobe-Paper-4-Collins.pdf |title=Towards a Renewed Submarine Capability |last=Collins |first=Jeffrey F. |series=Niobe Papers |number=4 |publisher=Naval Association of Canada |date=July 2019 |access-date=11 August 2020}}</ref>
