I'm on ventrillo with 3 Canadians at this moment, they are from Ontario. They just sort of sound normal, no real accent, they don't say ey, like people think...least these 3 do not. They do like jokes I'll admit that
There isn't too much difference actually. Just the little things, like when they say about, it might sound like a boat. They might say aye or Eh a lot too. I am not sure if I am getting this mixed up with something else but I think they might say Pop instead of soda. But I could be wrong.
