I have another one further to that on the building side, and this is really reduction or conservation, as there are many old high-rise office buildings throughout Canada. There are millions of square feet out there--we know this. The region of Waterloo put in a program with a bit of success, I think, on actually looking at all the water that's used--the taps, the toilets, and so forth--because we know there's a tremendous amount. Whether it is on the back end or the front end, whatever way you want to look at it, it's reducing the actual infrastructure costs that they're going to have as the economies expand.
I just wonder if you have any comments, Mr. Murray, on this one. Do you have any ideas or thoughts to help us promote this? I think it was a good program, and it's really tough for a region to promote it, because they have a limited marketing budget.
