In addition to screening passengers and their baggage, the Canadian Air Transport Security Authority (CATSA) is responsible for screening non-passengers entering into restricted areas at Canada's airports as an added layer of security for Canada's air transportation system

Non-passengers might include, but are not limited to:

• Flight crews
• Airport crews
• Caterers
• Maintenance workers
• Baggage handlers

Non-passenger screening (NPS) was regulated by Transport Canada in 2004 to enhance both airport and civil aviation security.

NPS involves random and unpredictable security screenings at mobile checkpoints located at entry points within airport-restricted areas. Most recently, several permanent checkpoints equipped with state-of-the-art, biometric technology have been erected at some of the eight largest airports.

NPS continues to evolve as a program. The one constant is the cooperation needed between Screening Officers and non-passengers to make the process hassle-free. The vast majority of screenings at NPS are quick and routine, however non-passenger cooperation helps to ensure screenings are carried out quickly and efficiently for the benefit of everyone involved.
