Pre-board screening (PBS)
In the screening process, passengers and their carry-on baggage are examined to prevent a passenger from transporting a prohibited item, such as a knife, firearm, incendiary device, or explosive, onto the airplane. CATSA is responsible for ensuring that passengers are screened at designated Canadian airports.

Hold Baggage Screening (HBS)
CATSA is responsible for screening checked baggage at Canadian airports through the use of high-tech Explosives Detection Systems (EDS) equipment. This responsibility includes purchasing, installing, operating and maintaining the equipment.

Non-passengers Screening (NPS)
CATSA operates a system for the random screening of non-passengers accessing restricted areas at Canadian airports. The screening applies to individuals such as airline personnel, airport employees, refuelers, caterers and maintenance personnel. CATSA's role includes the administration of the program, training of screening personnel and the purchase, deployment, operation and maintenance of all screening equipment.

Restricted Area Identity Card System (RAIC)
Together with Transport Canada and Canadian airports, CATSA operates an enhanced Restricted Area Identity Card (RAIC) system for all non-passengers working in a restricted area of the airport. Biometrics and centralized databanks allow CATSA to track, in real time, the issuance, verification and cancellation of RAICs.
