Canadian destroyers before the Tribal class

Which pre-Tribal Royal Canadian Navy destroyer offered the best lessons for later procurement?

The modified A-class pair is offered as a useful example of adapting an existing design for Canada, with a participant recalling better heating and insulation, although only two ships were bought.

The panel first distinguishes between Canada's two Tribal-class generations, then answers for the earlier class. The modified A-class pair offers an example of adapting an established British design to Canadian conditions. One participant recalls improved heating and insulation in the crew quarters, with some uncertainty about those details. Buying only two ships limited the scale of the programme, and the response attributes that small order to unwillingness to spend more. The procurement lesson is to adapt a proven design where local operating conditions require changes.
