Margret only got the rent control part right. We don’t need economists or other experts. Common sense suffices.  First, supply is not the problem. Toronto is always the magnet for new immigrants, and the overall immigration number didn’t grow that much recently. How come housing prices weren’t this crazy in the past? Second, speculation is the sole culprit. Third, measures: A) complete ban of foreign ownership (foreign-buyer tax inadequate), B) ban of multiple property ownership (this is to discourage speculation by local folks). All problems solved once A) and B) are implemented.
