Security is the responsibility of Mr. Boivin, Vice-President of Airport Operations.
As I explained in my presentation, this is not a simple issue. Some aspects of security are completely outside our direct purview. For example, criminal activities on the airfield are the responsibility of a number of government agencies. However, whenever we obtain information on such activities, we are responsible for conveying it to the appropriate agencies.
I'd like to ask Mr. Boivin to answer.
