Aww, that's too bad about your grandmother ;; But New York's pretty nice! If you're in the northern area, you should go to Saratoga Springs and Lake George! Both have some really nice views! The "North Pole" is also about an hour away from there, and it's definitely open during summer! It may be for children but I still love visiting, to be honest :B
Or if you're going to be in the Niagara Falls/Buffalo area you should definitely check out the falls if you haven't yet! I think there's a Hard Rock Cafe there, too, but I didn't get to eat there, so yeah.
...Of course, you could've done all this stuff already and I'm just being your average tour guide XD;
I wanna go to British Columbia! In fact, if I were to go anywhere in Canada first, it'd probably be there (despite Ontario and Quebec being considerably closer XD;).
