If you look at the Treasury Board website, there is a long list of federal custodians. The top 14, as Caroline mentioned, which are part of the sustainable development strategy, cover the majority. I have a list here. It's available, as I said, on the web.
Defence has 14,900 buildings in its inventory. As you go down the list, by the time you get to department number 11, it's 1,000 buildings; with department 14, it's 335 buildings. So the number pares down very quickly.
