Further on liabilities, then, let me ask a question regarding property management and Public Works. In the industry, they say that if a building is more than 40 years old, the costs of removing asbestos would be equal to the cost of building the building originally. You made passing reference to hazardous or harmful products, or something, and asbestos removal must have been a big cost in the renovation of the Wellington, West Block, and John A. Macdonald buildings, etc.
Have you measured the ongoing liability of the presence of Canadian asbestos in Canadian federal buildings across the country? How much of the total renovation cost was asbestos removal in the renovations of, for instance, those buildings you have ongoing now?
