Treasury Board established that in the eighties when there was a whole review of the land holdings in the national capital region. At that time the NCC was told they would need to have good reason to hold lands for their purposes for the national capital. So when we say it's a planning tool, it's where the NCC identifies lands that have a purpose for the capital now and in the long term. They don't necessarily own all those lands. If they don't own them they have absolutely no power over them. It depends on who the owner is and whether or not provincial or municipal zoning applies.
