The responsibility to file the eManifest on the House Air Waybill (HAWB) / House Bill of Lading (HB/L) lies with the freight forwarder for both air and sea freight.
The CBSA no longer permits freight forwarders to commission carriers to file on their behalf. Shipping companies and airlines will be required to file the information on master level.
The eManifest requires more data to be transmitted than the ACI.
The existing ACI is now needed for cargo routed via a Canadian port/airport which does not remain in Canada, whereas the eManifest applies to cargo with final destination in Canada.
