Toronto is also a relatively short drive from Chicago. It's actually far more similar to Chicago than to coastal NYC.
It is really geographically "midwest" by US standards, not "east"
When I was in elementary school in Alberta in the 80s we called this "central Canada." And that's how I still think of it. But there's a growing trend especially in Alberta to call this "down east" which is in my mind a very political way of "othering" what is actually geographically quite central and economically and demographically as well.
We used to have bumper stickers that said "Let those eastern bastards freeze in the dark". Funny to mention this on an article referencing the PET.
Ah, our geography. I live in Arnprior, about half an hour west of Ottawa (technically, my house is a couple of clicks from the Ottawa border, but we don't really start counting until the burbs).
Anyway. I live closer to James Bay than DC. Let that sink in a moment (and sink is what you will do if you attempt the drive).
Indeed - Chicago is considered "midwest" even though it is geographically in the eastern US. Maybe that's New York City-centrism from long ago?
Edmonton is as far west from the geographical centre of Canada as Toronto is east. I think it's a a bit of a stretch to call the GTA "geographically central". Economically and demographically, definitely.
The Weather Network, which really should consider geographic markers only, calls the GTA "central Canada". I think there would be an outcry if they started saying "eastern Canada".
