So where in Canada do people have this accent, anyway?

Fictional regions in American media.

From my understanding, its an Atlantic accent, although one that has mostly disappeared over the last few decades.

It isn’t quite like the stereotype, but I and others have it out here in BC. However, it’s more like “a-bow-oot” (with “bow” pronounced like the front of a ship). Likewise with “out”, it’s like “ow-oot”. There’s a small but distinctive “oot” on the last part if you listen for it. Not sure how many regions have it, though, or how much more distinctive it is than the USian version.

The closest I've heard was in one of the US states as a kid but I don't remember which. I haven't spent a lot of time in each province but I have stopped in some random places back when I actually liked driving and most people just talk more or less like in vancouver. no boots or ehs near my ears anyway.

Rochester NY here, I definitely hear it in Toronto / Ontario residents in the words "about" and "sorry", but I wouldn't go so far as to say it sounds like a-boot and soo-ry. I think that's an extreme exaggeration. The one word that's always a dead giveaway for me though is the word "process".

There's something about the O sound that's just more....O pronounced I hear when visiting the Ontario area. Although, I think it's rather us in the Rochester area that mispronounce it as AH more than O...we say PRAHcess and RAHchester rather than PROcess and ROchester. 🤷‍♂️

I’ve heard that it’s really subtle? Idk though, I don’t hear it either. I’ve had American coworkers make the aboot joke even when we both say about the same way to my ears.

Closer to the east coast, the more likely it is. Met a lot of people with the accent in pei

The first time i heard the accent not as a joke was in trailer park boys and even then it might be a joke since it's a comedy.

Born in BC, grew up in Alberta, my "ou"s sound like "oa"s. About -> Aboat, Out -> Oat, couch/coach basically sound the same lol
