Thank you, Mr. Chair. I can respond to this.
As mentioned earlier, there's a real dearth of information on vacancies writ large across the country. What we do have is data from the Canada housing statistics program on foreign ownership. We have that for four provinces. We have some data from the B.C. sales and vacancy tax on foreign ownership and vacancy among that foreign ownership component.
We have to extrapolate and impute what's going on across the country in the various other provinces to build up the estimate of revenues.
This is a new tax; it has not been imposed yet. We don't have any filers. We'll have a lot more information ultimately, but probably it's no surprise that the incidence is larger in Ontario, because of its size and population, B.C., Quebec and Alberta.
