Madam Chair, the act is fairly clear on the accountability process. There are a number of ways to enforce a lot of the stuff; whether it's through the enforcement officers or through the Minister's authority. Also, we have to remember that a lot of these lands that fall under the airport jurisdiction also are within the city. We follow very closely with the zoning requirements. We also require our leases to have permits that are issued from the city. So we have a number of ways, checks and balances, that we ensure that the proper rules are followed.
