We do have a Sustainable Development Policy. Work is underway for the Land Use Sustainability Framework which will incorporate that sustainability policy into a broader land use framework. We do try to strike the balance across the North in terms of land that is open for development and land that has been put aside for conservation and protection purposes. That figure ranges anywhere from 45 to 50 percent. It has to be unencumbered, 50 to 60 percent. Thank you.
