An Alaska-class flagship for Canada

Would an Alaska-class large cruiser suit Canada as a command and prestige flagship?

Yes in a pre-Second World War scenario; a modern version would need many more missiles, though the command-and-prestige role could still work.

For a hypothetical pre-Second World War Canadian fleet, the Alaska concept is judged a suitable heavy command and prestige flagship. The answer changes when the proposal is placed in the present. A modern ship serving that role would need substantially more missiles. With that change, the concept could still work for Canada.
