I'm witnessing it right now. Ireland is already completely in the hands of the Canadians and Cardiff has 20+ divisions who have made landfall and who are supported by the local revolt events (I didn't see it exactly, but it might have been a matter of timing, meaning, the Canadians simply got lucky that one of those revolt events gave them a province with a port as usually, the AI really is incaple of performing massive amph. assaults).
