U.S. border preclearance
Montréal–Trudeau provides border preclearance for passengers bound for the United States. This means that you will be screened by a U.S. Customs and Border Protection (CBP) officer before departure, and will not have to submit to any other formalities when arriving in the United States.
You must have all the required documentation with you, including a valid passport. Note also that you cannot take certain products, such as fruit from other countries, into the United States.
NOTE: Canadian and U.S. passport holders can now use the automated passport control kiosks to save time. The new process involves four steps:
Scan your passport;
Have your photo taken;
Answer the questions on the screen;
Present your documents to the CBP officer.
Passengers holding a passport from another country must follow the usual procedure and manually complete Declaration form 6059B.
NEXUS and Global Entry members enjoy the advantage of having access to a special express line through security checkpoints and in the U.S. border preclearance area where they can use Automated Border Control kiosks.
Note that in all cases, CBP officers are empowered to request a secondary inspection. You will be directed to an adjoining room and, if need be, your checked luggage will be recalled.
U.S. Customs and Border Protection will no longer process inadmissibility waivers at YUL Montréal-Trudeau. Travelers may continue to apply for inadmissibility waivers at the U.S. Embassy in Ottawa or at U.S. Consulates. In addition, CBP will continue to process the I-192 form, the I-212 form and the I-824 form at designated ports of entry. Waiver applicants are encouraged to submit their applications online via e-SAFE.
