I think it will still be possible to come if you top up local economy with $250k or so, which is nothing for people snatching up 2 million+ homes. Besides many investments are made by people who don't intend to set foot on Canadian or American soil, it's a quick win given how fast it's been climbing within the past 5 years. There is a whole industry outside of Canada that revolves around selling Canadian properties and as long as those people believe it will be going up the prices will be going up. The government, as some mentioned, cannot back out, it is too dependant on that tax money. I've been cycling a lot around the city lately and virtually every vacant or semi vacant piece of land has condo construction proposed, everything is "luxury" with bachelor units staring around 500k. At those prices I doubt that enough locals can participate in this celebration of life to guarantee even a 30% occupancy. As such we will see more and more foreign investment into real estate and prices will continue to climb (I wish I'm wrong by the way).As America closing its border for immigration, more international money esp. Chinese money will flow into GTA to increase real estate. Our government will not let real estate fails as property tax is government biggest income.
