Mr. John O'Hara:

I might come in there. I think it boils down to what is called the Pareto principle. More energy and effort is needed to get a relatively few number of vacant properties occupied than is the case to select larger sites or to rezone land for greenfield development, which is still a priority in some areas throughout the country. The latter is easier to do and can be done with far fewer time and resource implications. We should be doing both in parallel. Pursuing vacant properties alone will not be the solution to the housing crisis.
