One of the first things Trudeau did as Prime Minister was break the top-line platform promise that got him elected - he promised Canadians that the 2015 federal election would be the last one under the first past the post system. So I'd say from the standpoint of democracy, he had an absolutely horrible start.
Of course he went on to reap the benefits of the imbalanced first past the post system for two subsequent federal elections, one of which he called unnecessarily during the pandemic in order to consolidate power for his party.
I think him and his party have been vaporware since day one.
