Why Canada's geography points toward nuclear submarines

Should Canada pursue nuclear attack submarines instead of up to twelve diesel-electric boats?

Probably yes; geography and Arctic endurance favor SSNs, while a bespoke long-range diesel design would be costly and isolated.

Canada's current bases and patrol areas demand more range and endurance than most available conventional submarines provide. Designing a unique long-range diesel boat would be expensive, while the last Western precedents, the Upholder and Collins classes, are old and their builders have moved toward nuclear fleets. Canada's mature civil nuclear sector and Arctic responsibilities make participation in an AUKUS-style program a plausible alternative. Canadian SSNs would reduce American tasking, strengthen NORAD's northern defense, and create support infrastructure useful to allied submarines as well as Canada's own boats.
