We enjoyed staying in Ontario at the Fifty Point Conservation area. It is on Lake Ontario and within easy driving distance of Niagara Falls.
From Aurora, you could drive north to Port Huron, MI where we crossed the border into Canada. That is a much better crossing than the one at Detroit, and we had no delay and no difficulty in entering. We came back into the US at Niagara Falls, NY. Again, without difficulty.
BTW, I first visited Aurora, IN more than 60 years ago. To see your location brings back some very pleasant memories. I believe we sometimes crossed the river on a ferry instead of going up by Cincinnati.
