Thank you, Mr. Chair.
Thank you, Mr. Crichton for being here.
I want to go back to the noise contour issue, and the issue that I've heard a lot about as well. Perhaps you haven't had a lot of complaints about this because it's very difficult to find the number on the website of whom to complain to at Pearson airport.
As I understood the issue, to save the airlines fuel, Nav Canada was changing the arrival and departure runways in Toronto in order that they could use less fuel to get from the runway to the gates.
I understand flight path changes, but as we understood it, there used to be a distribution, a kind of even-handed distribution, of which neighbourhoods were going to experience the noise—depending on the weather, of course. If the wind is strong enough, you can't do this.
Can you comment a bit on whether that's something you've done and whether that has in fact changed the exposure patterns?
