Probably, but again that's just a side-effect of being a global superpower. The USA also has a bunch of staunch allies, whereas what does Canada have? Does Canada ever have giant "declare that we are staunch allies of your country"-fests? 'cause last time I checked a big part of the job of the President of the US was going overseas and making loving overtures to people whose populations want to kill Americans. Sure, they don't want to kill Canada, but that's because they don't care. Nobody particularly wants to kill me, but that's not because I'm a diplomat, it's because I don't matter.Diplomacy - I agree it is difficult to judge, but I would argue that America has more enemies in the global community than Canada does. So, Canada wins.
Self-sufficient and sustainable, yes. This is not the same as important. I'm not saying that Canada isn't a great place to live. It's just, if the Canadian economy went down in flames... what would happen? The US and some European powers would intervene. Everyone would be very sad about it happening to poor Canada. But globally, it would not matter that much. Wall Street is one of the biggest financial centers in the world. Canada doesn't have wall street.Economy - Yes the American dollar is worth more, but the gap is not that large. Also, Canada exports more resources than it imports, most of which goes to America. America, on the other hand imports more than it exports, and is therefore reliant on other nations to maintain it's economy. This means that Canada is more economically self sufficient and sustainable than America.
Again, being a great place to live is not synonymous with importance. Almost all the things you just said can be said of Norway, Sweden, Denmark, and Finland. And guess why the Scandinavians might be in Civ 5? Not because they've got the most wind power in the world in modern days, but because they had a great influence on history. Canada has had no influence on history, and that's what it comes down to. Music and movies are influential culture. The entire world is watching American movies and listening to American music. They're not being gay and thinking "the reason we can do this... Canada." Canada has no influence.Culture - This includes more than just movies and music. Besides, many American TV shows and movies are filmed in Toronto and Vancouver. Also, there are major video game developers in Montreal and Vancouver as well. However, culture also includes things like social policies. Canada is far more progressive in terms of education, racial equality, gay/lesbian rights, censorship, freedom of religion, environmental sustainability, and yes, public health care.
Also, seriously? I say Hollywood, Rock 'n' Roll, and McDonalds and you counter with 'American TV Shows filmed in Canada' and 'Several Video Game Developers'? Laaaame.
Civ is a history game. Sure, they have similar access to technology, and I will not be defending the American education system now or ever, but what has Canada done? (argument in your favor: Just looked it up, and it turns out Alexander Graham Bell moved to Canada when he was 23! Yay, go Canada! Still not enough.)Technology - Yes, Americans have invented more technology as a whole, but the quality and type of research that is currently in development is quite similar when you compare USA and Canada. Both countries have similar access to computers, labs and facilities. The education system in Canada is ranked ahead of America, thus producing fewer, but more capable researchers.
So? Again, not arguing that Canada isn't awesome. It's just not important. And it hasn't ever been. Thus, there are no grounds for its inclusion in Civilization 5. End of thread, end of argument.In a uni-polar world view, America is a superpower and Canada is not. However, in a multi-polar point of view, which, with increased globalization, is a more realistic perspective, America is a great power. Canada would fall in the Upper-Middle power category - and that is mostly because of it's small military and lack of nuclear arsenal.
