YYZ, pearson Airport, consists of 2 terminals, one and three. T2 was torn down and will be replaced by a new T1 pod eventually. There is a Sheraton Hotel on the property opposite T3 but reachable from T1 by the airport tram. T1 is used primarily for *A although both Etihad and Emirates are there also. I beleive Alitalia is in T1 also. Almost everyone else is at T3 but bear in mind there is some movement of carriers between T1 and 3. YTZ is the home of Porter airlines and is just off the downtown core at the Toronto Island airport called Billy Bishop .
