Indeed, to ensure that our emergency response plan is functional, it is validated on a regular basis through exercises, audited by Transport Canada and verified by CALEA. In fact, our security service is accredited by CALEA, as Mr. Rainville mentioned.
Both the exercises and the actual incidents, which are then the subject of feedback, allow us to improve and ensure that the communication channels and the alerting system are always at the cutting edge of technology and meet the needs.
When an incident is triggered, all key players in the response systems and services have access to a radio that allows them to listen and exchange communications immediately, pending the establishment of a command system.
A number of years ago, we adopted the widely-recognized incident command system, the international standard for these kinds of events. The system is regularly validated and tested, either in real events or by exercises.
