Yes. I think I've tried to deal with the problem of large ridings in the north, but in provinces, by simply including them despite their slightly lower populations. If they're unreasonably large, and you can't make them any larger...by including them as if they are ridings in all respects except their low population, similar to all the other ridings in a proportionality zone.
The question that came to me when I was thinking about this, however, is that I want to know whether the first nations, and the Métis and the Inuit, have a means they would be happy with for representation. And I think that basically it's not the rest of Canada's job to deal with that problem. I think it's a question that the federal government has jurisdiction over first nations and has to come up with a system within whatever other system we choose that satisfies them. And that could include their simply saying, “We'll throw our lot in with the general new system. We're happy with that.”
I think, for example, in Alberta, Manitoba, and Saskatchewan, it may well be that there will be a focused first nations interest group that will put up candidates, and I don't see there's anything wrong with that in exactly the same system as everybody else is using. They would get representation in a fair proportional representation system.
Edmonton has an area of something around 300,000 persons, and they would probably take five seats.
