Was your question specifically with respect to noise and the health effects of increased capacity and increased flights?
It's a very good question. I'm not close to that in my role in terms of noise and noise management. I know there has been a lot of work, and the minister and his predecessor in the previous government have really challenged Canada's airports to be more in tune with those challenges.
One of the big answers, of course, is the purchase of the most fuel-efficient, modern, quiet aircraft. When you look at our Boeing 737 MAX aircraft, or even a Boeing 737-800, versus a 600 or a 200 or something, it really does make a major difference. We're talking about a 10%, 20% or 30% decrease, both in terms of emissions and in terms of noise.
We find that to be the single best way to address it—to invest—and that requires us to be profitable and entrepreneurial. So there is that, but I can't offer too many more comments about noise protocols. We do participate at an industry association level with some of these, but I'm happy to get more information about that for you.
