[Rusty van Reddick]

Aboriginal people absolutely have distinctive accents though this is obviously more evident in on- versus off-reserve persons. I assume that there is a big difference between, say, Dene and Mi'kmaq but as most of the native people I encounter here are some variant of Blackfoot I'm not sure what those difference are. There is tonnes of academic research on this subject so get to the library.

But as to what I've observed- first, nobody says that there isn't huge linguistic diversity in Canada so I don't know why you framed this thread that way. I can hear differences in speech patters and vocabularies among Canadians from Vancouver Island, from Vancouver versus, say, Chilliwack, from rural versus non-rural Alberta, from Toronto (and not just Patois vs non-Patois; Jewish Torontonians have distinctive accents, many of them, too, as do people from all manner of ethnic groups); I know Newfoundland will have been discussed to death here so I won't but will add: Quebec. Too much fodder for discussion just in that province.
