We take things like that for granted if we grew up with them. I just wonder how much variations of English have blended thanks to TV etc. Kids here will use US and Australian terms all the time now.
Here in Bedfordshire, UK you may hear people add 'right' to the end of sentences like the Canadian 'eh'. They will also talk about 'old boys', but that can be someone of any age. There's an old guy (actually old) who empties the litter bins and he always says 'Alright me old mate?' to me even though I don't really know him.
Of course US and UK English have lots of differences.
