Here is how I see it. Although we have no accurate data, it would seem that air traffic operates within a more disciplined environment, with less disruption to the lives of the neighbouring communities.
Take Pierre-Elliott-Trudeau Airport, for example. People living near the airport complained about the noise. Accommodations were made, and all live in harmony. This type of regulation could be applied to other areas.
I find it interesting that, when I listen to the people from out West, they sound just like the people who live in Charny. I can relate to what they are saying; the noise that they describe is identical to what we hear in Charny. So the problem isn't a local one, nor is it unique to one area. It is common to all of Canada, and involves a single industry.
We understand the requirement of the just-in-time delivery system, as explained earlier. These operators have time constraints and, because they have a tight schedule, they must work around the clock.
We think that the industry should be able to adjust, as the airlines have done; flights arrive from all over the world, yet they manage to respect the schedules. But there are a number of things to consider before setting an exact decibel level.
Of course, noise-level standards are one option. Attitudes must also be factored in. Earlier, the Western delegation expressed some doubt about the workers' ability to judge how much noise they were making. Engines are left to idle for long periods of time and alarms sound when they are put into reverse. Employee attitudes aside, it is also important to maintain cordial relations with the neighbouring residents; this must be done through Transportation Agency regulations.
I have touched on a number of points. I'm not sure that it can be expressed in terms of decibel levels, but that is one of the components that should be considered.
