Sometimes you can get a pretty good price if you book your flight and hotel as a package deal. I assume you'll be flying United, but you can book it through Air Canada because they code share their flights. If you use aircanadavacations.com you can book the flight and hotel together, which will usually save you some money over booking separately (the only problem is that you have to pay the whole price up front, and can't change your hotel booking - which is why they give you a lower rate). You can also try the same thing through Expedia or Travelocity.

If you want to save the most, and don't have any specific hotel in mind, try using Priceline. There you specify which area of the city you want to stay in, the class of hotel you want, and the price you want to pay. They have agreements with various hotels to sell rooms at deep discounts and if your bid is high enough, they book your room. They only drawback is that you have no say over which hotel you get booked into, and can't specify anything more than the general area you want to stay in. Also, you can't cancel the booking, and your credit card is charged immediately. The advantage is that you can get a very nice hotel for significantly less than what you would pay otherwise.

A word of warning about Priceline, don't go for anything less than a 3 star rated hotel (try for 4 if possible) because things can get pretty dodgy if you bid on a 2 star or less. Anytime I've done at least a 3 star, I've had decent rooms in nice hotels.
