I think if you extrapolate from British Columbia, you end up at over 600, but if you say that you don't really need 600 people to get a representative group of Canadians, you could probably do it with half of that, right? I do think breaking it down by region makes sense, even breaking it down by province. The riding level might be too specific for something like this. It would require too many people. We could probably do it with 300 people, depending on how you did the math. At the end of the day, you want to represent this group of Canadians, and that's actually as much a math equation as anything else. Maybe Mario can talk about this later. I have no idea.
What it does allow you to do as you get slightly bigger numbers, say for instance 300, is you can start to select by gender, you can start to select by ethnicity, you can even start to select by partisanship if you want. You can have a representative body, because you're not going to get it with a town hall. There's a huge selection bias because people are opting into it based on their pre-existing passion for the issue.
I'm a PR advocate and one of the first people to say they're not even close to representative. These are PR folks who are turning out to push PR. I happen to think most of them are right, but they're not representative.
