Whats wild about affordable housing in Canada is that for every newly built unit we lose 15. Yet almost nobody is talking about that part. You cant build your way out of the problem before you plug the leak. But there are obvious misaligned incentives to do that. The value system of our economy and culture seems to be obsessed with making basic needs a profit center, at all costs, regardless of the consequence.
Where do the 15 go? Destroyed?
So I expect the answer to your question to be "they are still available, but at a rent higher than $750".
