U.S. CBP Pre-Clearance Station

Montréal–Pierre Elliott Trudeau International Airport has a U.S. CBP Pre-Clearance Station where goods en route to the U.S. can clear U.S. Customs upon departure from Canada and prior to arrival in the U.S. This eliminates the need to clear customs upon arrival back in the U.S. To utilize this service with an ATA Carnet, contact CBP - Montréal–Pierre Elliott Trudeau International Airport at 514.394.7377. Note that the ATA Carnet white re-exportation voucher will have to be validated by Canadian Customs PRIOR to U.S. CBP validating the yellow re-importation voucher at the pre clearance station in Montréal. Also, the goods will have to be available for examination both for Canadian and U.S. Customs upon departure from Montréal.
