Well? If I remember correctly they have a pop of around 30 mil? What are population projections for Canada in the 21st century? Will they reach 100?
If they do, wouldn't their country (being a developed economy and having a fair amount of energy resources) become a major power?
And then suppose that something happens to the US? If Canada annexed some of the former US territory it could reach something like 200 million and with a poplation like that could it become a new superpower?
BTW When will Canada surpass Russia (which currently has a declining population and will go below 100 million sometime this century)?
