The biggest concentration of them are located in Quebec (the province).
Not to be confused with The Brayons, living in the northern part of New-Brunswick (a lot of them will speak a fluent, yet in a funny accent, english. And if you address a citizen in french, they'll respond in a "good enough french", but you oughta know some english!).
New-Brunswick officially declares itself bilingual (french-english). Go figure.
Cajuns people (called "Acadiens", "Cadiens" or "Cayens" in french) also have their own dialect called Chiac (pronounced SHE'ACK (no pause)). It's spoken by most cajuns of southern New-Brunswick, although canjuns' elite tend to snob it and will either use a well-spoken french or english. That's mainly because chiac's known to be of a strong redneck-from-the-far-east french pronunciation plus a few english words. One can use less or more english... it's complex. I personally never lived there to fully grasp it, although my roots are from Quebec's far east.
Members of the band Radio-Radio raps in chiac. check it out on You-Tube.
-Hi, I'm a quebecer and consequently a french canadian. What about you?
Some chiac, in 'Cliché Hot' from Radio-Radio :
-1 frippe, 2 frippe, 3e frippe aussi?
-T'as pas besoin d'prescrition, ta première frippe est free!
translates to :
"1 fry, 2 fry, a 3rd fry too?"
"You ain't need a prescription, you're first fry's free!
note that Quebecers say "frite", not "frippe"
