The system was developed as a proposal. We worked in this case in conjunction with the airports in Toronto, Ottawa, and Montreal. The material was published. We set up special websites. We held public meetings with the noise management committees in all three cities. A whole host of activities went on, I think for the better part of a year. I'm looking at my colleague—yes, it's something like that. It was pretty transparent and open.
We spoke to all the groups who historically had expressed interest or concerns about aircraft noise. Of course, the airports in all three cities are very sensitive about this, and they all have noise management committees with members of the public involved. It was pretty extensive consultation, and again we can provide that to you. But I can tell you, as someone who's been in this business all my life, there's less noise as a result of the changes we made than before.
