In terms of the approach on buildings I think what you're referring to are situations when we are in buildings that are close to the end of their life and need very significant refurbishment. That's the bulk of what the real property folks deal with.
When buildings get to that situation, there's a cost-benefit analysis done, where we look at all the options: would it be better to sell the building, would it be better to invest and refurbish the entire building, would it be better to look at some public-private partnership to see if one could build a new building?
I think the approach is to look carefully at all the available options, look at which one has the best value for the taxpayer and still meets the needs of the public service, the people who will be working in those buildings.
The answer is different depending on that analysis.
