In terms of customs, CATSA doesn't have a role. CATSA is responsible for passengers who are departing. Our role is very prescribed. Transport Canada is our regulator, and we're responsible for aviation security.
Essentially, Transport prepares a list of prohibited items that are not permitted on the plane. Our job is to detect them. We do that by screening passengers and their baggage, whether it's carry-on or checked luggage.
We also have a screening program for airport workers. The people who work at the airport who go from the public side to the secure side have to go through certain checkpoints, and we screen them as well. If we find a prohibited item, then we intercept it. That is essentially our mandate.
