If you are looking for cheaper options that that, I recommend the Airport Rocket (bus #192) which goes to the Kipling Station. Get off at the Bay station and walk approx 1 block to the hotel.

The third option is the Pacific Western's Airport Express bus - get off at Royal York and take the subway at Union Station on the Spadina line to the Museum stop and it will be across the street from the Royal Ontario Museum.
