Holding your nose while voting is something that Canadians have been doing for decades. In most cases people tend to vote for the party, and the candidate is irrelevant. (please note that most of us who do this are not literally holding our noses; it's an expression that's become part of our collective elections-related vocabulary; it means to choose the best of a list of less-than-great choices)I think this is actually harmful to democratic societies since it doesn't encourage candidates to actually be good, it just encourages them to not be the worst possible option.
I try to evaluate the candidates of the parties I am considering. Under no circumstances will I vote for a right-wing party. So that leaves the other three to consider. This last time around, since you could run a dust bunny as a Conservative and it would be elected, the choice of Conservative candidate doesn't really matter - it's a foregone conclusion in my riding that he or she will be elected (actually, I can't remember ever having a female MP for this riding).
I rejected the Greens, since the candidate lived in Calgary and didn't have any information posted online. If you're going to let your name stand in a riding, the least you could do is live there.
So it was between the Liberals and NDP. The Liberal candidate was a pastor - someone more likely to oppose the promised assisted dying legislation. So that was a strike against him, and I'm not in favor of legalizing marijuana for anything other than strictly medical reasons. That was a strike against the party.
The last party standing, and the one I didn't mind anyway, was NDP. One of the campaign workers went to bat for me with Elections Canada when the Returning Officer decided she wasn't going to let me vote, because it would inconvenience her, poor dear.

There was one election when the NDP candidate lost my vote. She actually said at the all-candidates' forum that she was running because she thought it would be a fun thing to do.
Hello - far too many people let their names stand for that exact reason, and it's sometimes a "holy crap, what have I gotten myself into?" moment if they happen to win because the voters are seriously not in favor of the other parties.
