Any interesting POI between Toronto & NYC

I will be travelling between Toronto to NYC. I am asking to see if anyone has any good suggestion for any interesting Points of Interests (POI) along the way. The attach map is the planned route, I don't mind taking a small deviation to see something interesting along the way. Any suggestion anyone?
