Speech pattern and typographical variations across Canada

[middeljohn]

It's no secret that the States are littered with various accents - Midwest, Brooklyn, Appalachian, African American Vernacular, etc. Meanwhile Canada is thought of to have one accent across the country.

For the most part I'd say Canadians sound most like the US television accent, but I've noticed a couple of regions with their own distinct accents:
- Black Creek in Toronto, the second and third generation Jamaicans speak with a hybrid Canadian-Jamaican accent, despite having been born here.
- Rural parts of south western Ontario. They emphasize sentemces differently, I'm trying to imagine it in my head so I can describe it, but I don't if that'd be correct. They say "oat" and "a-boat" (but not oot and a-boot as the stereotype). Also, I've only noticed this within the blue collar types in these regions.

What other accents are there that you know of? I've never actually heard any of the Newfoundlander accents.

Also, with all the immigration over recent years, and larger ethnic enclaves developing than we've ever had before, is it possible that certain areas of cities could develop their own accent (such as the Italian-American influence to create the Brooklyn accent)?
