The given reason for this is to make housing for hundreds of thousands of people coming to Canada. This is laughable, considering the houses will be high-value, low density R1 zone lots designed to pad developers pockets and do little towards giving people places to live.

Mid to high density housing in transit-centric areas will do infinitely more to solve this problem, but is far less profitable. So either Doug Ford continues to blatantly pad the pockets of his friends and goes through with this plan, or he does the right thing for Ontario and commits to higher density development in places that already have available land.
