The CBSA defines Freight Remaining on Board (FROB) shipments as follows:

a) Marine – Cargo on a vessel that is not being discharged at a Canadian seaport but remains on board the vessel for furtherance to its ultimate destination outside of Canada

b) Air – Cargo that is not being discharged at a Canadian airport but remains on board the aircraft for furtherance to its ultimate destination outside of Canada Supplementary Cargo Report - a document submitted by a freight forwarder for shipments that have, or will be deconsolidated from an air or marine cargo control document for freight remaining on board (FROB) shipments only.

Cargo that is staying on board in Canada is subject to a supplementary filing instead of an eManifest HBL filing. A supplementary filing is what we're currently sending to CBSA for all types of goods (Imported or Stay on board) and is basically a paired down version of the HBL filing we'll be sending for eManifest.

An exception to the rules for Stay On Board cargo is that the freight forwarder doesn't need to file a supplementary if the cargo stays on board in Canada and ultimately discharges in the U.S.

An eManifest filing needs to be completed for U.S. goods traveling through Canada to an overseas location, like Asia or Europe (U.S. exports through the port of Montreal to Europe, for example). The CBSA expects freight forwarders to provide electronic house bill data for US loaded in-transits.
