Not sure what point you are trying to make? What does capital gains exemption have to do with anything? If anything we should follow the US and only exempt a base amount.

I'm saying use taxes to disincentivize speculation.

There's a reason the market became detached from fundamentals when rates were lowered. I'm not saying we don't need to build more. Of course we do. But I'd rather not build homes that go to more investors than FTHB like is currently happening. Otherwise the situation only gets better if you over build.

Also yes, it only takes a small number of speculators to create unaffordable housing. Real estate is a market based on benchmarks. You should look into the history of the BC market and how a small number of speculators drove that market bananas.
