Safety and security are an essential part of airport management. With this in mind, Aéroports de Montréal is responsible for protecting both people and facilities and ensuring that airport regulations are followed.
In addition to ADM’s Airport Patrol and Fire Service, several other agencies responsible for law enforcement, security, safety, intelligence and crime control operate at the Montréal–Trudeau and Montréal–Mirabel airports, each fulfilling the responsibilities specified in its mandate.
- Canadian Air Transport Security Authority: passenger searches at pre-boarding screening checkpoints in the terminal, searches of checked luggage, supply of search equipment, employee searches at restricted-area access points.
- Canada Border Services Agency: customs, immigration, inspection of goods and passengers.
- Royal Canadian Mounted Police: enforcement of federal laws, support of federal agencies, combating organized crime, in-flight security, investigations prior to issuing access passes, intelligence.
- City of Montréal Police Service (SPVM): 911 service, armed intervention, crime control.
- Canadian Security Intelligence Service: intelligence
- Transport Canada: regulation and control with regard to airport and aircraft safety and security, background checks prior to issuing access passes, tests and audits
In addition, the airlines work to ensure the security of aircraft and cargo, that access to aircraft is controlled and that aircraft are searched in the event of a threat. Tenants of buildings next to the airport are responsible for controlling access to restricted areas within their own facilities and following applicable regulations.
