The Canada Border Services Agency (CBSA) requires ocean carriers and freight forwarders to electronically transmit data to the CBSA 24 hours before the loading of cargo at a foreign port. For containerized cargo, the data must be submitted 24 hours prior to loading. For bulk cargo, the data must be submitted 24 hours before the arrival at a Canadian port. The conveyance report must be submitted within 24 hours of departure from the last foreign port. Empty containers require a conveyance and cargo report to be submitted 96 hours before the arrival at a Canadian port. For voyages that are less than 96 hours, the reports are required at the time of departure. Any questions or clarifications regarding these policies can be addressed to the CBSA EDI Hotline at 1-888-957-7224.
