Speaking of electoral reform... the Citizens' Assembly in Ontario has decided that mixed-member proportional (MMP) is its preferred alternative to the current first-past-the-post (FPP) system. See DemocraticSPACE (who also designed an MMP system for the purpose) and Idealistic Pragmatist.
Prince Edward Island's electoral reform attempt also would have implemented MMP. B.C.'s option, on the other hand, was for the single transferable vote (STV). [That option, for those who don't know, got 58 percent "yes" votes when it needed 60 percent, so wasn't adopted, but will be back on the ballot.]
This is one of the best aspects of federalism--different jurisdictions experimenting with policy; however, it does wind up being rather uncoordinated. It's certainly possible that we could see 10 different voting systems for 10 provinces, not that there's anything wrong with that. But the clamor is growing in Quebec, where there are three major parties and two growing alternatives, and New Brunswick just had a "second place winner" election in which the Liberals won despite losing the popular vote, so there are certainly other provinces that might be exploring other options.
If Ontario adopts MMP, there will definitely be a lot of pressure on the federal government to at least examine the idea of PR. (Note: the NDP introduced a motion for consideration of electoral reform, which will likely be ignored. But I always wonder why the NDP doesn't make electoral reform their #1 priority in any support deal. Yes, the short-term gains are uncertain, but one would think the long-term survival benefit is way, way bigger than in any other area. ATM fees, for instance... seriously?).
