There are a few that are added, just say, for the territories. They end up getting double. Labrador gets another one, because there has to be an even number per province in this system. So, if the province currently has an odd number of representatives, it would be divided by two and rounded up. So, Nova Scotia would have 12 instead of 11, and Newfoundland would have eight instead of seven, and that extra member is for Labrador, because I think it would be important to Labrador to ensure that they have their own riding as well.
To be fair to the north, they would remain as single-member ridings as well, because there would be two members elected in each riding. That would effectively double the representation of the north, but if you're looking at, say, six members out of 340-something, I don't think that's such a big deal.
