PR is not a good method and as I've said every single time it gets a solid look by the people it gets turned down. What has it been, four or five referendums now? 6?

It's not popular the moment people give it some real thought. And obviously the people of the provinces make up Canada. Even Ontario, our largest province, shot the idea down

As far as your reasoning goes as to why you want it I can understand that and I'm not saying it's invalid. But there are other ways to achieve that and to be honest proportional representation will achieve the opposite in some of those cases Proportional representation means you have no local representative and you will be totally unrepresented in parliament directly. Furthermore the Idea of pR is to create fewer majorities. Which means that you never have a government that has majority support. It's a coalition of people who don't have majority support and didn't run on a unified platform.

So by it's very nature it doesn't do what you want it to do. There are other ways to tackle some of those problems that would be better.

As to the liberals the liberals were plenty weak. The results are often however not what you thought they would be. Very often these coalitions become about personal power and achieve wealth for their members but don't do much for Canada or the country they serve. Jack meet his pension and a bunch of business contacts, he will be very wealthy. Justin is making tens of millions of dollars with the connections he laid. Both left Canada in a mess. That is proportional representation and it's core

And I hate to break it to you but it's actually not that hard to get a majority under PR. It happens less frequently but it does happen and worse you're thinking that only one party would want to go back to first pass the post. But chances are that's not true. The liberals and conservatives could easily look at moving back to a first past the post if they don't like sharing power with people like the NDP. Or did you forget about that?

Even the block might very well be happy to work with a minority government leader to bring back first past the post considering that proportional representation would probably hurt them the most

It would be very easy for it to be rolled back, so you're not really changing anything

In short PR does not do what you want it to, and people realize that when they're forced to take a long hard look at it and make a choice. Your concerns are valid but there are other ways to tackle them. PR has been proposed on a provincial level numerous numerous times and is always shot down. It will be wiser to look at reforms that make sense and can be sold to the public
