Some liberals did vote in favour of electoral reform, and supported the motion, and had it as part of their platform. But I get your point that they are ultimately responsible for not passing reform. Maybe time to try again.

Ideally it would be put to Canadians on whether we want to move forward with PR or STV/ranked ballot. Status quo not being an option. Arguably democracy is eroding, this a meaningful pro democracy reform.

My biggest concern with PR is that it would give a platform to extremists, but I'm less concerned about that these days as they seem to have a platform anyway. The next thing I think we need to consider is whether PR makes sense in the context of Canada, we aren't a small country geographically and we aren't homogenous. Local representation matters.
