The estimates say that there are between 65,000 and 100,000 owned but VACANT homes in Toronto.

And that right there shoots down your attempted emphasis on there being more buyers than listed homes, pretending there is some kind of compelling meaning there.

There is no compelling meaning, there: You are scrutinizing the wrong part of the body, you are coming up with the wrong diagnosis.

Yes, Toronto, like Vancouver, is in a disease state, but it is a disease state characterized not by SUPPLY pathology, it is instead characterized by USAGE pathology.

And that disease of pathological under-use is the result of COMMODIFICATION, of converting "homes" (word written on paper) to what functionally might as well be big gold bricks that overseas money likes to buy and leave sit like, well, big gold bricks.

Building more houses will not solve that manner of billions of dollars of overseas money flooding in, which is why your treatment plan (build more) will fail to return affordability here.
