I'm going to answer in French, even though I don't know certain technical terms in that language. I'm sorry about that.
First, there is an airport security system in Canada. It is a highly complex system because, at an airport, there are local police officers, border officers, investigators and auditors from Transport Canada, who audit CATSA's systems and procedures. There are also people for CATSA and perhaps other federal agencies, including the Royal Canadian Mounted Police. It's a complex system. In my view, the line structure isn't clear.
If I understand correctly, CATSA is solely responsible for screening. The only things that employees try to detect are prohibited items. If they find some banned item, they can tell passengers that they may not be in possession of that item or hit the red button and call someone who can conduct an investigation. Under the current system, CATSA has very limited responsibilities.
In response to your question and to what Mr. Sela said, I would say that we in Canada have the technology to monitor the identity of airport workers and to ensure security. It's called the restricted area identity card. This card has won awards in the field of innovative technology in Canada. It is also a model for other air authorities in the world. Uniforms are part of the system and are not a threat to air security because the biometric card is very reliable.
Under the current system, the sole task of CATSA workers is screening. They must detect prohibited items. This is not a security function, but rather an observation function. If CATSA calls on subcontractors, I don't think that's a problem because their task is not really a security one. I'm aware of your security concern, but I think that, if this function remains an observation function, hiring subcontractors will not pose a real problem.
I'll now let Mr. Sela answer.
