Does Canada have electoral alliances? Like, we won’t pull our candidate but we’ll do a switcheroo. Haven’t heard of it for a single seat but for elections we usually have them. Party A and Party B join forces so that the votes that weren’t enough to get a seat are used by the partner that got more votes in that district.

Edit: it’s called Apparentment and you don’t have it
