As far as culture goes I tend to think more in terms of North America as opposed to Canada or the US individually. There is just so much exchange of ideas and culture between the two that the lines become pretty blurry. Except of course the US has the population and economic resources to do so much more in regards to scientific and technological research and application. As well as ensuring our territorial integrity, that they share so much with us is yet one more reason to remain loyal to the US
