London is about an hour and a half west of Toronto. Not exactly Mid-Western Canada!
Now, I'm from Toronto, and I really don't think I have the 'oot and aboot' thing going. But EVERYTIME I talk to my grandparents, who are American and from Brooklyn, they always make fun of me and tell me I say ABOOT. EVERYTIME. IT makes me CRAZY.
That's okay tho. They say WUATAH

.
I don't hear myself saying those words with an accent. But then again, I guess I wouldn't.
And all I can say is, just try to Annex us! It went so well the first time!
