CATSA works at every departure checkpoint. The problem I was referring to involves customs at arrivals.
For departures, Montreal does not really have unreasonable line-ups. The CATSA Plus program is partly operational in Montreal. At departures, things are going well, they do not have the problem. The situation is completely different in some other Canadian airports, but, in Montreal, things are going relatively well.
For us, the bottleneck is in customs for arrivals. As I was explaining to you, we are in the process of taking care of it.
