If your flight originated outside Canada or the United States and you need to take a connecting flight to a U.S. destination, follow the signs "Connections to the United States". There are two possible options:
1- Your airline offers the option of automatically transferring your luggage, and you have a boarding pass for your connecting flight:
You will be directed through the transit lane to pre-boarding screening checkpoint “C” and then to U.S. Customs and Border Protection (CBP). You do not need to worry about your checked baggage. However, U.S. customs officers are authorized to recall your luggage, if necessary, for manual inspection. If the customs officers do not yet have the information on your luggage at hand, you will be asked to proceed to the waiting area.
2- Your airline does not offer the option of automatically transferring your luggage:
- You must pick it up your luggage from the carousel, then follow the normal procedures for international arrivals, then for U.S. departures.
