That is helpful. When this information came out initially, some people were making assumptions that these 47,000 property owners were perhaps required to register. The case is we do not know. It could be that a good number of them are required to register and a good number are not. I thank Mr. Culhane. It is useful to have that clarification.

Will the RTB witnesses provide more information on these 47,000 unknown rental arrangements which we do not know how many are or are not required by law to be registered? How will the RTB go about finding that out, addressing it and ensuring that, within that figure of 47,000, the ones who are required by law to register do so? The witnesses talked about their general approach to it, but will they take a particular approach to those 47,000?
