Transport committee  I would like to say that I don't believe we've identified the need to regulate or control that beyond what we already do with the airports.

Transport committee  But the experience helps to drive policy, so that's something that I think we need to take a look at. But I can't tell you we're about to put something into place, because there are no plans, to my knowledge.

Transport committee  The other part of our responsibility clearly is not to put regulation in place without need. One of the things we have to justify through Treasury Board is to make sure when we put regulations in place that there is a need. So that's the trade-off.

Transport committee  That's not my area. I won't comment.

Transport committee  I think it's fair to say that until recent times, beyond that 10-mile limit, which doesn't necessarily have a deep scientific basis, typically there were not issues because the aircraft were at sufficient altitude that the noise hadn't been an issue. That may be part of what's ch

Transport committee  It was my understanding that the process for ADM is the same. The process isn't really the same in the case of ADM. It's not a direct delegation. We're asking ADM to have a consultation process.

Transport committee  All airports accept all complaints.

Transport committee  The airports are responsible for managing the noise procedures and they are the ones who are responsible for accepting the complaints within the context of the airport.

Transport committee  I need to check my facts on that. It seems as if we are at cross-purposes. I'd like to verify that point.

Transport committee  I think the points of Nav Canada relate back to some of my opening remarks at the start of this session. We deal with noise exposure forecasts, and I explained at the time that any level greater than 35 was an issue.

Transport committee  I think that's something we would have to look at. The point I wanted to make was that the noise levels at altitude are unlikely to cross any known limits. So obviously any involvement by Health Canada would be appropriate. But compared with the noise in the vicinity of an airp

Transport committee  Absolutely.

Transport committee  The consultation is required when they're changed, if they want to change the procedures, either because it's a new airport and they put them in place or there are changes that need to be reworked for other reasons. It's not ongoing. It's—

Transport committee  Yes, sorry.

Transport committee  It has escaped me for a minute; I apologize.
