Canada

For the record, Carney's new Minister of Democratic Institutions is a supporter of electoral reform. This is a really good time to be pushing for this, because we've clearly got allies at the top.

Contact your MPs, tell them how important electoral reform is to you.

An Alternative Vote system does not solve the major issues of First-Past-The-Post, and can still have wildly distorted outcomes relative to vote preferences. Unless combined with multi-member districts (aka Single Transferable Vote) it's barely/not an improvement for Canada -- it's a convenient option for the largest parties because it rarely makes a difference to the outcome and the votes all trickle back to them anyway, so they can make a change without making a change.

Here's an article worth reading. https://www.fairvote.ca/expert-dennis-pilon-sets-the-record-straight-about-the-alternative-vote/

The only desirable outcome of electoral reform is one which introduces at least a degree of proportionality -- Single Transferable Vote if you're really itching for a ranked ballot, or Mixed-Member Proportional Representation otherwise (my preference - but either would be a great improvement).

GCP Grey also did a newer video on the single transferable vote

Those were very informing videos, thank you!
