It has been, in the past customary for leaders of parties that fail to win a majority (after being in a minority) mandate to resign. That Trudeau a) called the last election at all and b) failed to resign after getting the same result as when they entered into it... is frustrating.

It certainly created an appearance of weakness that I suspect fed into the situation with the convoy.

Also probably tactically stupid, because he got to hold the blame for all the post-COVID problems.
