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.
