I don’t know for sure, but under PR, 4 or 5 “presincts” around Kitchener would be amalgamated to select 4 or 5 members of parliament from the pool. I’m not positive if Greens would need 20-25% of vote for 1 seat across all of Kitchener, but it would be the Green that got the most votes that would get the seat. Someone around here knows more than me, but I don’t know if there is a risk of party infighting if “the best they can hope for is x seats”
Most voters are going to spend a couple of hours watching CBC, or at best, look at a summary of party platforms, and be told only about leader/party politics. No one is out teaching people how to vote under our system. Low information is a problem for democracy.
