Canada has hummed and hawwed about electoral reform for decades. It just hasn't been worth the required political capital to make it happen for any of the leaders.
The election of EU representatives is separate from the election of representatives in parliament. Canada could end up like the UK was (in the good old days), with PR for the European elections and FPTP for its own national elections.
In either case (EU or no EU), we must push for the government to implement proportional representation, and that starts by getting organized: [email protected].
As far as I know, [email protected] is the only online community dedicated towards this cause.
So a lot of the current work is building the movement, and getting those that already support the movement organized.
We know a federal election is coming up, and the more this movement grows, the more politicians will bend to our demands (as they should in a democracy).
