As a Canadian, the quickest way that I can spot a fellow Canadian is by listening for their pronunciation of "out" and "about". It's not an "oot" sound, it sounds like "oat". Most Americans I've heard typically round their "out" sounds, so it sounds more like "ow", like what someone exclaims when they're hurt.

As a Canuck, I’ve read this before, but literally everyone I’ve ever met from Ontario westward says out, not oat. I’ve only ever heard oat from the Atlantic provinces.
