I'll jump in.
This is a fascinating angle and a fascinating lens to the discussion because it's about how we apply the values and principles that we believe and know are important and operationalize them. It's much harder in a lot of ways to think about how you're going to put this into practice.
Even for representation in the House of Commons, if we started to think along the lines of what if Canadians living abroad had their own representative, how would that work in terms of the constitutional formula around representation by population and ensuring that there is a balance in a riding? We protect communities of interest. We have a geographical sense of how big we want a riding to be and how many people we want to have in that riding.
An MP for Canadians living abroad would be a totally different kettle of fish. I'm not sure how we would make that work constitutionally anyway. I'm not saying we shouldn't. I'm just saying that we don't have a formula for that right now at all. I find that sometimes in these conversations there is a tendency to say that we'll have a senator for that because it might be easier, but it wouldn't be because the allocation of senators is by province and by region.
This would be an extremely complex thing to do, and it would definitely have constitutional implications.
