This is really locale dependent. For instance, when YYZ operated under Transport Canada, the airport was federal property and policed by the Mounties. As soon as it came under the GTAA, out go the Mounties, in comes Peel Regional Police, and the place becomes an operating establishment in the province of Ontario (i.e. not federal property any more...).
This will likely mean provincial booze regs apply where your airport is not operated by Transport Canada.
