Let me start. I'll just give you a couple of comments.
This legislation is separate from the Canada National Parks Act, so although it adopts the ecological integrity definition, it is a separate piece of legislation and it flows from 30 years ago.
The roots of this flow from a report called “Parks 2000” by John Theberge. In that “Parks 2000” report, John Theberge laid out that new types of parks that Parks Canada would create might involve more partnerships. They already involve many partnerships, but perhaps more partnerships.
The Rouge is a model of that, and in moving to a new model wherein you have these partnerships and you're bringing parks to people, the idea is that you cannot be high-handed, that you can actually support what has already been done, such as the greenbelt plan.
The basis for the Rouge legislation and plans is the greenbelt plan of 2005. They gave the Rouge the policy priority in that area. Ecological integrity and practicality, as Dr. Woodley said, are relative, and in the Rouge, Environment Canada has actually—for Great Lakes “areas of concern”, which the Rouge is—put down definitions of what they think ecological integrity means. Those definitions are based on whether the biodiversity is similar to what that area could support, whether the water running through the rivers is clean, and whether it meets standards.
There are already, then, criteria established by Environment Canada for what ecological integrity would mean in the Rouge. In the Rouge, the Environment Canada standards are that 50% to 60% of the park landscape would, in the long term—and this could be 40 or 50 years away—be in a natural sort of cover, and that natural cover could include some types of agricultural use.
