Welcome and hello from Western NY: not far at all from parts of Ontario, but very far away from other parts!
I travel up to the Golden Horseshoe quite a bit, having friends and family up that way.
I have also done a few trips to the London area, passed through to/from Michigan a few times, a summer trip to Tobermory, several trips to Wolfe Island and the Kingston/Thousand Islands area, and a road trip home from Winnipeg via Kenora. All that is to say, I have been around the province of Ontario a good bit, but still haven't seen all there is to see by any means!
