5sdad had the question about which accent is the easier to understand.
Some of the Canadian women have an accent I could listen to for hours. And, consider that Canada being Canada, there are many accents within Canada, regional , but also, French, Italian, and many more.
Richard - one time I was sitting at the McDonald's in Dryden and there was a group of older men visiting at the table next to me. They were clearly speaking English, but I could not for the life of me make out what they were saying. I think that it was as much the "lilt" in their voices as anything that was causing the disconnect. (I always enjoy conversing with the folks up that way.)
