In my last job, I was in British Columbia. We were looking at this question in earnest a year or so ago. We determined that about the closest thing to a source of information that would give you this information is the real estate sector. They'll track through their contracts of purchase and sale, but what we found in British Columbia is that it's not aggregated anywhere in a way that you can do any form of analysis on it.
To your first question, Mr. Grewal, I think the only jurisdiction that is tracking purchases according to the source of the income, whether it's foreign or domestic, is British Columbia now, and that has only been since June or July.
