The question was asked about what measures should be taken. Chris mentioned green infrastructure; you can call it low-impact development or whatever. That's what you would apply to those new, urbanizing areas where you have the ability to implement that. One of the problems we have with implementing low-impact development right now in Canada is that a lot of the measures are very well known and used in Europe and in the U.S.A., but we don't have the experience and the information on how these measures perform in Canada under the climatic conditions we have.
So if you're a developer looking to develop, you're going to use the old method because your engineer's going to know exactly how to engineer that, how to size it, and put it in. TRCA, with the help of the Credit Valley Conservation Authority and the Lake Simcoe Region Conservation Authority, established the sustainable technology evaluation program, which is generating the types of engineering and design data, performance data, that's required to develop that kind of thing. But we need to do it on a broader scale.
