ACI eManifest is a program run by the Canada Border Services Agency (CBSA) that requires carriers to electronically transmit shipment information to CBSA before the goods arrive at the Canadian border.
This program is designed to improve border security and facilitate the processing of commercial shipments into Canada
The eManifest system requires carriers to submit shipment information such as the carrier's name and contact information, the shipment's origin and destination, and a detailed description of the goods being transported.
This information is used by CBSA to identify potential security risks and to determine whether the shipment complies with Canadian laws and regulations
Carriers who fail to comply with the eManifest requirements may face penalties and delays at the border.
It is important for carriers to ensure that they are properly registered with CBSA and are submitting accurate and complete shipment information in a timely manner
