A shopping list would be sensors and a means to track, detect, and engage a cruise missile. If we had a shopping list and unlimited resources, that also means point-defences, for example with a ground-based defence system that would protect our most important sites within the Canadian land mass, which we don't have now. From a ground-based or defence point of view, this is something we don't have. That might be the biggest difference from the configuration we currently have.
