First, you need to get around the urban blockade. Stouffville forms a blockade between the northern part of the proposed park and the actual heart of the Oak Ridges Moraine. You need the Pickering lands.
Second, they were already announced as a federal green space preserve, or a significant amount of them were, in 2002. We should carry that forward to link to the moraine.
Three, the bigger the park, the more room you have to balance the needs of nature, the needs of visitor use, and the needs of farming.
I guess the last one is that in Markham, the Rouge is only 5% forested. If you go across into Pickering, it's 25%. So there's a little bit more work to be done on the Markham side. You could trade lands. There are fallow lands in the Pickering area that aren't being farmed right now where you could say, “Farmer, you're in the ecological corridor. We don't want to disadvantage you. We'll give you a slice of land over here. But we do need this backbone of the park, that 600-metre ecological corridor, to have a place for nature and public use.”
