Map showing regional accents in the US and Canada.
Meh. It’s close, but there’s literally no way my Vancouver people talk exactly like they do in the T.Dot. (To start with, those weirdoes don’t even say “dude!” What’s wrong with them??) I’ll wager that little blue line marking the border might be more porous on the left coast than the right. And the accents on Vancouver Island (where my aunt and grandparents live) are a whole thing in and of themselves.
Also, pretty much nobody in my city says “aboot” or “eh,” so just you shoo that old canard out of your heads as soon as possible. (Fucking Tim Horton’s and their Canadian cultural imperialism!)
