Is there a special name for the southern peninsula of Ontario? The area is in roughly the shape of an arrowhead, pointing more or less at Detroit and bounded by Lake Huron and Georgian Bay on the north and Lakes Erie and Ontario on the south. The neck of this peninsula is roughly at Toronto going up to Georgian Bay.
If I google for Ontario paninsula, all I get is hits for the Bruce Peninsula, which is only part of the region I’m looking at.
This area is simply called Southern Ontario.
Oh wait. This is the dope. Here’s the cite!
Southwest Ontario. http://swotc.ca/wp-content/uploads/SWOTCmap3.pdf
Seriously, that’s it.
Southern Ontario works as well.
Well, since the OP specified Toronto as the neck, I’d dispute that you’re being a bit too narrow! Southwest Ontario is more, well, south and west of Toronto!
Once again, cite.
I’m really not this nitpicky. Honest!
PS to Grey: Are you from the county that is relevant to this topic?
If you’re curious, the other “barb” of the “arrowhead” is the Niagara Peninsula. However, I don’t think that there’s a specific name for the entire region beyond “Southern” or “Southwestern” Ontario, any more than there’s a fancy name for the Lower Peninsula of Michigan.
Based on your initial cite, Southern Ontario is not the answer either. Southern Ontario includes a whole bunch of area to the east (all the way to the Ottawa River).
The Lower peninsula is sometimes known as the Mitten.
Fair enough. I don’t think we divide it the way you’re looking for, then. Southern Ontario is divided in Southwest, Central, and East. Yes - we don’t add the South part to the Central and East. So if I’m understanding you correctly, you’re thinking of some or all of Central Ontario + Southwestern Ontario. I think that’s the best you’re going to do.
I agree with D18 - when I was living in Kingston and Ottawa, I always thought of that area as Eastern Ontario, not Southern Ontario.
Fair enough. I was hoping there was some colorful name for this region based on its shape (much like the aforementioned Mitten), but I guess no one has felt the need for one.
If the OP is looking for some meta-regional name like the UP, there isn’t really one. Tourism Ontario call Southern Ontario everything from Ottawa west to Midland and south to Windsor. Northern gets Sudbury, the Saulte and Thunderbay.

But that’s the Tourism people in the government so really what can you expect. 
The Ministry of Health Ontario Newsroom sent out something about Southwestern Ontario which in the Press Kits details work in Owen Sound which ties back to the top portion of the OP’s barb.
Basically we demand rigidly defined areas of doubt and uncertainty! I can’t think of a colloquial name like the Nape, or Barb.
Slightly OT, but Ontario extends far enough south to allow a trivia question with an answer that many find surprising:
Q: How many US States have some part of their territory north of some part of Canada?
A: 27
The whole area is shaped like a baby elephant trumpeting if you look at it sideways. I don’t know of anyone who calls it that, though.
I’ve heard it jokingly referred to as the Canadian Riviera.
I grew up in Sarnia. It’s Southwestern Ontario.

Technically, it was, but I (as a native Torontonian) never thought of it that way.
To me and my friends in Toronto, there were two Ontarios: Northern and Southern. The dividing line was roughly between Parry Sound and Pembroke. North of that was Northern Ontario, and anything else was southern.
So, Ottawa, Kingston, London, Windsor, and Cornwall are in southern Ontario; while Sudbury, Kapuskasing, Wawa, Sault Ste, Marie, and Thunder Bay are in northern Ontario.
I’m no authority on this, and I cannot claim to speak for those in Kingston or Ottawa, but that’s how we looked at it from Ontario’s biggest city.
Aside to all: I once found myself in Capreol, Ontario; and was reminded of something an old acquaintance told me: “Fools rush in where angels fear to tread, and Capreol, Ontario isn’t a place where you’d ever find an angel.”
My family and friends in Southwestern Ontario used to call the area around Windsor and Leamington “the Banana Belt”…
Didn’t really seem appropriate when there were no bananas, although there were cactus and Carolinian forest in Point Pelee National Park.
To enlarge a bit, you rotate the map about 150 deg clockwise. The Niagra penninsula is one of the feet, Windsor is at the tip of the trunk. Owen Sound was once referred as the asshole of the elephant. This from a neighbor of mine who showed me this, and spent part of WWII training there.
Its obviously an elephant balancing on it’s trunk. Sheesh
