While I agree that we should allow more six plexes and multi plexes in general, the entire housing problem is in reality a transportation problem, not a housing one.
If we built reliable, 24/7, two way trains out to Barrie / Peterborough / Guelph, and those cities had streetcar networks within them, then we would have an exponential amount more space to work with, and density would naturally follow the train lines as people try to live close to them.
It is problematic that our "solution" to the housing crisis is to tear down reasonably sized single family homes and replace them with cramped shoe boxes sized condos and apartments. Really rushing to all be miserable living in Tokyo and Manhattan rather than trying to build out more of the rather ideal streetcar suburbs.
Apple is such a piece of shit company.
