I think each particular complaint would have to be looked at specifically. I can tell you generally that the implementation of these changes was done over, first, a consultation period that lasted a better part of a year. However, of all of the changes in the flight paths that were adopted, none of them resulted in aircraft flying at lower altitudes. In fact, most of them are at higher altitudes and therefore less intrusive from a noise point of view. I think what you may be hearing about is that with the change in some of the patterns, people now see airplanes in places they didn't used to see them. There's a difference between seeing airplanes and hearing airplanes.
We'd be happy to look into the specifics of any particular complaint but we've had surprisingly few complaints since the implementation of this system, which was back in February. Both Dorval Airport and Pearson have had the same experience. We need to look at the specifics.
