I have the pleasure to fly to most of the major airports in the world. I can say that the noise abatement procedures of Transport Canada, Nav Canada and the local airport authorities are some of the strictest in the world.
You have certain countries that don't have any at all, because aviation is number one to them in the Middle East, but throughout Europe and most of North America, including Canada, they have very thorough procedures. Our pilots are trained on every single departure. They brief the procedures and they follow the procedures. If they don't, we're quickly made aware of it.
