A Harry DeWolf-derived corvette risks replacing the patrol ships it should complement

Could a Harry DeWolf-derived design serve as the Royal Canadian Navy's corvette?

It is accepted as a useful starting point, with a warning that a second batch could be treated as a replacement and fail to increase total hull numbers.

The Harry DeWolf hull offers useful space and Arctic flexibility for a more combat-capable vessel. A derivative could provide Canada with a credible starting point for a corvette-like role. The procurement danger is political rather than purely technical. Branding it as a second batch could invite the government to retire the existing patrol ships, repeating the British experience in which Batch 2 Rivers were treated as replacements before the older hulls proved necessary.
