This large international airport is located outside of Toronto. It has fairly easy access to it from the roadways, and has good parking if you are familiar with it at all.
If you are flying out, you can stay at the airport hotel (Sheraton) the night before and park your car for a reduced rate for a one week trip. This is a nice benefit and good thing to know if travelling from Buffalo to use the airport. The hotel is connected to the airport, so once inside you just have to get your luggage to the right area of the airport (they have a transit system).
Since its a real international airport, there are not many places you cant get to direct from Toronto. Flying to most from Buffalo you would have to connect in NYC or Detriot/Atlanta etc.
The airport itself is fine, a little older, and it shows. But the stores are ok, the walks not too bad, and the people are nice.
