Yes. Central Canada is where 'eh' is said the most; I say and hear it a lot. Atlantic Canada certainly has the most distinctive dialect, and you can immediately hear it's gaelic roots. When a Canadian accent is being poked fun at, it's usually an extreme version of how the prairie provinces speak.

Then splash in some Quebecoise and that will really diversify things. Much of rural Quebec may not even speak English altogether. But you can tell the difference between Quebec French and France French pretty easily, with the latter sounding smoother. I've never been out west but I assume that BC and Alberta is the most 'normal' of the Canadian differing accents.
