Security Screening Wait Times

CATSA encourages all passengers to arrive at their departing airport well in advance of their flight. Many airlines advise passengers to arrive two hours in advance for domestic flights and three hours in advance for US and international flights.

Working As a Screening Officer for One of CATSA’s Partners

The Canadian Air Transport Security Authority (CATSA) fosters a culture of accountability, excellence and trust through its people, its partners and its governance. CATSA values its partnership with contracted security firms, who employ screening officers. Together, we ensure critical elements of the air transportation system are secure - from passenger screening to baggage screening.

All screening officers in Canada are security cleared and rigorously trained on a program built on the principle of continuous improvement. The classroom, on the job and computer and web-based training never stops and evaluations – both written and practical – are conducted frequently. Screening officers at Canada’s airports must be CATSA certified.

The role of screening officer is an important part of ensuring the security of air travellers, airline staff, airport employees and others who work in and travel through our country’s airports. Screening officers are also vital to Canada’s overall security measures, working as part of a team that keeps our country, our citizens and our skies safe.
