see, i listen to all sorts of accents, and i don't think there are enough similiarities to get the two confused. i know you know what im saying eh? i dun remember if i told you this, but when i was in costa rica, i hung out with a bout 9 canadians, from quebec. and we picked apart eachothers accents. and the biggest one i can remember off the top of my head is, for most californians: we say something like, "that was fun, huh?" where as you may say "that was fun, eh?"
please correct me if that is an incorrect generalization.. =P
