For any flights that Air Canada has that would fly within the domestic United States, my understanding is that the domestic implementation of that portion has happened and that they are in the process of moving towards the implementation of flights flying from Canada into the United States.
There are two programs in the United States. One of them is called APIS, and one of them is called secure flight. The APIS program is one that is used by customs and border protection, and it's very similar to a program Canada has where advanced passenger information, the passenger name record, is sent to the U.S. government, and it's sent for the purposes of customs and immigration admissibility, as people land in the United States and have to go through customs.
