ACI – Air Mode
Conveyance Arrival Certification Message (CACM)

Data Requirements

With the implementation of Phase 2 of the Advance Commercial Information (ACI) program, completed in 2006, all air carriers are required to electronically transmit air cargo, conveyance, and (if applicable) supplementary cargo data to the CBSA four hours prior to arrival in Canada or before the time of departure if the flight is less than four hours in duration.

Under Phase 3 of the ACI program, known as eManifest, the CBSA introduced new functionality.  As of June 9, 2013, the CBSA requires air carriers operating a conveyance that is transporting specified goods, or their authorized service providers, to transmit a Conveyance Arrival Certification Message (CACM) to the CBSA using an Electronic Data Interchange (EDI) method at first point of arrival (FPOA).

On May 6, 2015, the regulatory amendments supporting eManifest were published in the Canada Gazette, Part II. The publication of these amendments is the final step in the regulatory process and makes the eManifest requirements, as set out in the regulations, legally binding. Air Carriers who do not comply with CACM requirements may be issued monetary Administrative Monetary Penalty System (AMPS) penalties.

The CACM is required in addition to the cargo and conveyance Advance Commercial Information (ACI) previously transmitted according to the prescribed time frames as described in the Reporting of Imported Goods Regulations.

The requirement for the CACM replaces the arrival process that is based on the Estimated Date and Time of Arrival (EDTA) provided by air carriers as part of the advance conveyance data. The CACM allows carriers to meet the reporting requirements under section 12(1) of the Customs Act electronically.

The air carrier (conveyance operator), or a service provider authorized by that carrier to transmit on their behalf, prepares and transmits a CACM to the CBSA through EDI. The CACM must be transmitted electronically to the CBSA without delay after the aircraft that is transporting cargo (specified goods) is cleared by NAVCAN to land at an airport following arrival in Canada.

Conveyances exempt from transmitting ACI data to the CBSA are also exempt from transmitting the CACM. Exempt conveyances must be reported to the CBSA at the FPOA, under section 12(1) of the Customs Act, in the same manner as they are today. However, if an air carrier (conveyance operator) chooses to voluntarily transmit an electronic ACI conveyance report for an ACI exempt aircraft (i.e. commercial passenger aircraft that are not carrying commercial cargo; empty aircraft), the CACM must be transmitted in order for the arrival status in the CBSA system to be finalized. For example, if a carrier's common practice is to transmit an electronic pre-arrival ACI conveyance report for aircraft with no cargo on board, they must also transmit the CACM.

The following data elements must be transmitted as part of the electronic conveyance arrival certification message:

Upon receipt, validation and acceptance of the CACM, the CBSA system updates the status of the conveyance and related cargo, and acknowledges the report of the conveyance and cargo with a section 12(1) “Reported Notice” to the originator of the arrival message. This notice indicates the carrier operating the conveyance (as identified by the CBSA carrier code transmitted within the conveyance report) has met their obligation to report under section 12(1) of the Customs Act for the conveyance and all shipments detailed on cargo documents that are linked to that conveyance. The CACM will generate any release (for shipments requesting FPOA release) and referral notification messages accordingly.

The carrier must keep on file all section 12(1) “Reported Notices” that it receives and make them available to the CBSA when requested during compliance monitoring, supported by the requirements in the Transportation of Goods Regulations.

Third party service providers may continue to act as agents of carrier companies and submit the CACM on their behalf. However, consistent with the law of agency, the carrier company's CBSA-issued carrier code must be used.

Carriers and authorized service providers must register with the CBSA's Technical Commercial Client Unit (TCCU) to have their profile created or updated for the new message and notification transactions.

Detailed information on transmitting the CACM is available in the ACI/eManifest Non-Highway Conveyance Arrival Certification Message Implementation Guide available on the EDI section of the CBSA Web site.
