Nothing has been written about Ontario here, and neither Wikipedia nor Wikivoyage has an article we could draw one from. If you know the place, that makes you a better source than anything we have. Tell us what is worth knowing and where you got it.
We show Toronto as the capital of Ontario. If that is wrong, tell us what it should be and where you read it.
