Some of the problems you mentioned are there in western democracies. It's not really about either a majoritarian system or PR. A crisis of confidence in parliaments and their role and their power is very much affected by globalization and the loss of sovereignty of countries, which means parliaments are not the institutions they were 20, 30, or 40 years ago; therefore, tinkering or changing the electoral system won't necessarily meet those objectives. In New Zealand they tested, for example, political efficacy before and after reform, and it didn't go up. Confidence in institutions didn't go up.
On the other hand, we do know that if you reform the system, the rules of the game, there are some mechanical things, if you like, on which you do have an impact. The number of women in parliament is likely to go up under PR and turnout is likely to go up under PR. There are specific things that can be achieved by changing the rules of the game. For other things, it might in fact make things worse rather than necessarily better.
It's really a question, again, as we said at the beginning, of identifying the central problem you want to address. It's not a crisis necessarily, but are there particular issues you think are really a problem in Canadian politics? In that case, what are the best rules that actually match that particular problem?
However, there's no single best solution to all of the issues that are facing you, just as there aren't in other political systems or democracies either.
