I would suggest that when you have a standard, you can then make that kind of determination. Until we actually have a measurable, scientifically based, human-health-focused standard of what is acceptable and what is not in Canada, you can't really make that decision. You're making it just on the basis that it's noisy. Well, “noisy” doesn't tell you a hell of a lot.
That's why I keep pushing this simple little thing that we all go skating around, because it would start to tighten things down. When people phone in a complaint, the airport could then say, “Well, it was within the standard.” That's legitimate.
