What the secretariat keeps an eye on is the rust-out costs that are brought to our attention. The rust-out costs would typically be described to us in terms of the portfolio writ large, but from time to time we do become very aware of particular cases of rust-out, especially where they go to health and safety issues.
Two examples I would give you have to do with museums that were quite recently given a certain amount of cash over a number of years and the National Arts Centre. Both had rust-out problems that were funded in the order of $100 million over a number of years, the bulk of that going to the NAC.
However, in direct answer to your question, we don't track at the secretariat, on an explicit basis, what the maintenance costs are in a given building.
