I think they would be in a better position to identify the specific costs. What we would say is that the situation in Toronto has been pretty dire now for a couple years. It's not just Toronto. Look at the Lower Mainland. It's in a very similar situation.
The fact is that the project completion time frames are getting pushed out further and further, in part because, as you point out, there are only so many bodies available. The fact that Ontario hit this past July an unemployment rate of 1.3% I think says it all. Pretty much everyone who can work is working right now.
As for the cost implications, I would turn it over to the home builders.
