Toronto

'"The Boss' has decided she wants to go to Toronto for her birthday this September as she has always wanted to visit Niagara Falls.
So I have a few questions for my fellow V-flyers:
1) Planning on spending a night at a hotel at Niagara but how many days will we need in Toronto itself and what is there to do?
2)Want to earns some Miles/Tier points so planning on Flying VS to either New York or Boston and then making the short hop up to YYZ
