Yes.
The Rouge is part of the Toronto area of concern under the Great Lakes Water Quality Agreement, and, under that, Environment Canada did a scientific report called “How Much Habitat is Enough?” They said that for a healthy watershed—good water quality and biodiversity—you need a minimum of 30% to 50% forest cover. The Little Rouge River watershed, where the park is, has 13% forest cover. They said 10% wetland; it's 1%.
Now the reason that this is so important is that people have lost the economic aspect. The premise of the province's whole growth plan was the Rouge watershed plan. It said that to offset the flooding and erosion of extreme storm events from climate change and also from the runoff from planned urban growth, we have to restore forests and wetlands or our liabilities are going to skyrocket, insurance-wise, and with infrastructure and property damage.
The restoration in the existing greenbelt plan and Rouge park plans was premised on that due diligence. If the federal government ignores that, they're ignoring the due diligence at great risk. We've seen what happened in Calgary, the southern prairies. Even in Toronto, one big downpour is $1 billion in damage; it basically shut down the financial district for a couple of days.
