That last Toronto shot is killer, as is the third Montreal shot. The first Ottawa pan is impressive for its sheer scope.
BTW, I think Detroit's waterfront skyline isn't that flattering, at least taken from head on like all of the tourists and voyeurs. As most of the tallest buildings are at the front and the skyscrapers are aligned away from the river, it hides the rather vast built up area behind it.
I'd love to see you get an angle either from "behind" the skyline, or if it's from the other side of the river form Malden Park in Windsor:
