Crossing the border on this lane
Advance cargo data has to be filed before the truck reaches the bridge. Into the US, CBP's ACE Truck e-Manifest links the customs broker's entry to the shipment (the PAPS number, now labelled Simple Bill). Into Canada, CBSA requires eManifest data at least 1 hour before arrival, and the broker can release the goods through PARS. FAST is a program for pre-approved low-risk trade: the driver holds the FAST card, and the carrier and importer must also be approved.
