Maybe just as a point of reference, I need to acknowledge the work that we do with the conservation authority to get back to the wetland area, and I apologize for that. But also critically important to your question and the fact that when we're looking to develop greenfield, I'll say, Toronto has very little greenfield left. It's pretty much all urbanized. But to your point, in terms of meeting stormwater quality management requirements, inherently if it's a large enough subdivision, as part of the stormwater management plan the developer through their engineering firm will propose a stormwater pond/wetland. So it's inherent within the makeup of that subdivision to manage stormwater runoff twofold. One is to control flow to minimize erosion in the stream to which it discharges; and second is the water quality component, which is critically important.
In Toronto's context, we have developed wet weather flow management guidelines. What we're seeing an awful lot of is redevelopment, and so we've imposed stringent criteria to developers who are developing in the city to actually provide on-site stormwater controls, and we prescribe a level of flow as well as water quality control.
