Actually, it shouldn't make any difference whether the money is foreign or domestic or from Mars. Fact is there is a significant portion of the condo and freehold market in the hands of speculators, which is fine. But if a buyer is trading real estate just as someone trades stock, the same rule on the Capital Gain should apply. Buy a residential property and hold it and rent it (or not) as part of a passive investment strategy, no change. Pay Capital Gains tax on 50% of the gain. Trade and flip real estate as a income source, foreign or domestic, pay Capital Gains on 100 % of the gain. Simple solution to quell the market. Perhaps too simple for our Peerless Leaders in Ottawa.
