The version that many people in the US and in Canada use is very close. In fact, just from the accent you wouldn't be able to tell a difference between a Canadian and an American unless you pick out certain words. Obviously both nations were once holdings of England, and that is why the language is predominantly english. Why are the accents so similar? Is it because we are right next to each other and one influenced the other (or vice versa)? Also, are Canadian spellings like the US or the UK (i.e. colour or color, tonne or ton, etc)?
