I don't know all the ins and outs of the new plan. I don't understand all the gobble-de-gook about targeting foreign speculators,   but I do know this: this new revenue stream will be added to all house prices of all real estate across the GTA. I can guarantee you it will just be the new cost of doing business, as agents add 15% to everybody and only some of that going to the government as intended. Homes will actually get more expensive, thus being utterly counter productive.  You can take that to the bank.
