Which takes me to my third point. Your options are limited in Toronto because you don't have other large airports nearby available to you. You said communities tend to grow up around airports, and that's exactly what's happened around Pearson, because when Pearson was put there, Mississauga and Brampton weren't anywhere near the size they are now, and they've developed those cities close to the airport, which has partially contributed to the problem.
I was in Edmonton this summer, and I was impressed by the fact that they had a very positive relationship with the surrounding communities and business community, and it's because they don't have that build up around the airport. We have the Pickering lands, which were secured many years ago, and there's a lot of space around that.
Wouldn't it be sensible to put an airport there, given the opportunity to develop a situation where you don't have that problem?
