I'm sorry to perhaps not sound as clear as would be ideal, but the problem is that there are many sources of that type of information.
An airport is a fairly non-homogeneous environment, with many employers and many workplaces that are often somewhat isolated. Some are not in the main terminal, and so forth.
Sometimes, in a workplace in one of those areas, there could be a question that would be raised in the group of workers. They could decide to go to the transportation security inspector and raise the question there. That has happened and can be very effective.
They could also go to the airport security people, because, as was mentioned, they have an obligation to report any concerns that they see, or they could go to their own employer who could come to us.
Additionally, there are other environments that have information come up about an employee. For example, let's say they had a Facebook account that said they were an airport employee, and something of concern arose there. That could then be reported by anyone to the RCMP or someone else.
There are many venues. They are all responded to by Transport Canada, very seriously. Any question like that immediately comes back to our transportation security group. As I said, if we have any reservations at all about what we hear, the clearance is suspended while we investigate.
