In the recent Canadian federal election, so many people were running for election to Parliament in one constituency, there had to be a special ballot to fit all 91 names.
This happened in Carleton, where Conservative leader Pierre Poilievre was running for re-election. He lost.
TL;DR (but I did read it) - this wasn’t an attempt to ‘rig’ the election or confuse voters. It was done as a rather clever protest of our flawed electoral system and the need for electoral reform. It would be patently obvious all of the other 87 or so names on the ballot were all protest entries and would only take a person about 10 seconds to find PP’s name or the few others with official parties on there.
