Atlas Obscura is one of the largest, most well-known and most impeccably awesome archives of amazing places, foods and experiences in the world.
Here is their list of places to see in the Canadian province of Ontario! From a Toronto bookstore with a random book vending machine, to a 98-room castle that bankrupted a multimillionaire , to Hamilton, Ontario, home to over 130 different waterfalls and cascades, to barren, rolling red hills, Ontario is chock full of interesting places! How many of these awesome sites have you been to?
Note: Some of these you cannot visit or see anymore, which have been marked with (Permanently Closed). So therefore, if you haven't already seen them, I don't know if you'll ever be able to completely finish this list.
Note 2: This is as of May 4, 2024. Sorry future people, there will definitely be more that can't be added.
