Could try Wawa. Never been there myself, but my brother spent a few weeks a summer up there over many years, lots of fishing rentals. Definitely checks the rural roads and plenty of canoeing boxes, most of the lakes they fished had a strict 10HP limit. Not a heck of a lot in SW Ontario beyond farmland, though, one would have to get north or east of Toronto entering from Detroit.

Google says Wawa is 10h 9m from Dayton, so nevermind, it is outside of the OPs parameters by 9 minutes
