From the article: "Those fees have so far amounted to a total of $24.5 million — not enough to develop a single social housing project, according to housing experts."

I don't know about construction costs in Canada, but in many cities in the United States, 24 million dollars could renovate at least 120 homes, assuming a cost of $200,000 per renovation. Renovation is more expensive than building new. You could easily build 240 modest homes on undeveloped land with 24 million dollars.

I've left them half a million for administrative costs.
