One point seriously missing, and which has been a thorn in the side of our democracy since its dawn - the unaccountability of parliamentarians to their "Constituents". 

We chose the proportional representation system in 1994 to avoid the threat of gerrymandering and the weaknesses of the first-past-the-post voting system. But we've seen for the last twenty years how MPs and MPPs are beholden only to the party that was gracious enough to list them - a weakness far greater than any shortcomings of other systems. If we can't change the constitution, then we can force MPs and MPPs to hold regular public meetings with the people they are supposed to represent. And by "regular meetings" I do not mean rallies and events, I mean actual town hall meetings where their job is to listen, and explain themselves. Advertised locally and obviously in multiple languages.
