I have to admit it's difficult for me to commit at this point on this request. What I would say is that this would be an extremely complex exercise that may take a while to arrive at assumptions that make sense. Given the complexity of the issue, there are so many factors at play.
We know for sure that we're going in the right direction in terms of reducing building costs. As I mentioned, it's between 3.2% and 5%; that's the GST value. Some provinces may also jump in. It would be an extremely difficult exercise. I wonder whether the number we would end up with, based on the quality or lack of quality of assumptions because of the lack of data, would really be informative.
