When I was in university, I spent three terms in Ottawa working for Radarsat. I'd have to take a cab across town a few times every week, and inevitably, the driver would hear me ask to be taken to our Nepean office, and he would say, "Are you British?"
Funny thing was, I had a roommate who actually was British (he was born in Norwich). He said, "You don't sound at all British. Mind you, you don't sound Ontarian, either. I can't tell
what your accent is."
OTOH, when I was in Chicago for the 2000 Worldcon, there was a young lady who latched onto me because of my Canadian accent. Every time she saw me she'd run up to me and say, "Say 'out'! Say 'out'!" And when I said "out", she'd start jumping up and down giggling.
So I guess my accent is in the ear of the beholder. (Or maybe it changes, depending on where I am and whom I'm talking to - I did once manage to keep up a conversation with an Aussie I'd just met, using an Australian accent for about 15 minutes. He finally said, "So, mate, where ya from Down Under?" I changed back to my normal voice and said, "Actually, I'm from Toronto." He got a kick out of it.)
Michael Hogan (of BSG fame) probably has one of the strongest Canadian accents you'll ever hear.
I saw him on stage a few times last year, and he told a story about how every so often, a director on BSG would say to him, "You're getting a little regional there, Hogan!" He was actually trying to tone it down.
There are, of course, regional distinctions even there and I find the Newfoundland accent particularly perplexing (I'm guessing it's more of a dialect than accent).
Little bit of column A, little bit of column B. They have phrases heard nowhere else in Canada, but they also have a very strong accent. "Lard t'underin' Jaysus, b'y!"
