Thank you, Madam Chair.
I'd like to make a comment before I begin my questions. During the presentations by the witnesses who appeared via videoconference, the sound was so bad that it was practically impossible for the interpreters to do their work. When the committee receives guests via videoconference, I wonder whether it would not be worthwhile to do a sound test before the meeting begins to ensure that the communication will be good. That is the end of my comment, and I will leave that with you, Madam Chair.
My questions are for the Aéroports de Montréal, because that is the area I know best. However, I invite the other witnesses to intervene without hesitation if some of the issues speak to them as well.
Some of the points in your presentation were of particular interest to me, such as your statement that you co-operate with many organizations, including Transport Canada. That department is the regulatory body in charge of enforcing acoustic criteria. I have asked about the nature of those acoustic criteria about twelve times. Acoustics are a clear concept for musicians like myself; they are measured in decibels, frequencies, reverberation and even in soundproofing terms. Every time I asked the question, however, no one was able to provide me with any clear acoustic criteria, nor with any scientific numerical standard. Would you, Mr. Massé, be in a position to clarify these acoustic criteria you are attempting to have respected?
