What is Conveyance Arrival Certification Message (CACM)?

The carrier or its authorized agent must submit the CACM to the CBSA after the aircraft is cleared by NAVCAN to land at the airport. The CACM must be submitted in addition to the cargo and conveyance reports. Exemptions to the CACM rule are conveyances that are also exempt from the ACI data requirements. If the air carrier voluntarily submits an ACI conveyance report for an exempt aircraft, however, the carrier must also submit the CACM. If a third-party agent submits the CACM to the CBSA, the agent must use the CBSA-issued carrier code on the document.
