The Greater Golden Horseshoe has a population of 7.5-million with politicians predicting 15-million by 2030.  The population is forced to grow through immigration,  though 42% of existing jobs will be lost to automation and artificial intelligence within 20 years.  Canada also permits foreign investors to buy up homes and land without any limitations or foreign investment tax.  These are the causes of rising prices, not the Greenbelt, which is much skimpier and disconnected than shown in the accompanying schematic.  Interesting how the article included  two satellite photos of real GTA subdivisions but did NOT include a satellite photo of the Greenbelt which would reveal its rather insignificant size.  Housing tracts approved since the 1950s can still be built in the Greenbelt, and it also includes some large quarry operations. The Greenbelt is all about politics, not real conservation.  Over-population hasn't worked anywhere in the world yet. It is not sustainable.
