This is my last question. I'll say that I was a bit distressed, more than disturbed. Part of my theme has been about retaining existing building stock as opposed to knocking down and land-filling; and then you came out and said that if we want to get where we want to go, the only way to get there is to knock down, land-fill, and start over.
I find that really disheartening. We've learned that 75% of the building stock will be in place when a lot of the targets we've committed to kick in by 2030. It's not realistic to knock down 75% of the building stock.
How are we going to get there? I get the point that it's not cost-effective to do it now, but, again, is it a regulatory issue? What's the lead point to get us there? If we impose new standards, and we went to the kind of work we're doing on all new buildings between now and 2030, that's only going to give us 25% of the stock. How do we get to this retention of our existing stock? Is there any hope there?
Anybody is free to comment on that.
