Should Canada join Type 83 or a US nuclear cruiser program?

Would the Royal Canadian Navy benefit from joining the Type 83 or proposed US nuclear cruiser program?

The US nuclear design is a poor fit, while Type 83 might make sense only if Canada later needs a large command and air-defence ship.

The proposed American Defiant is described as a massive nuclear-powered cruiser, making it a poor match for the Royal Canadian Navy in this discussion. Canadian participation in Type 83 is treated as conditional on the programme returning and Canada needing a larger command ship. The distinction between the combat systems and their eventual hull also matters: the discussion describes continued work on Type 83 systems despite uncertainty over putting them in a large surface combatant.
