I do agree that only quick fix to bring down prices is stopping immigration. With 15% youth unemployment in Toronto its still called racist for saying so however. But I see your point that a GST rebate for investors is very silly.

Of course continuing near the current immigration level still requires rezoning all over Canada. I still think that's the best plan, as it is the only thing to deal with the land shortage. BC had done it, as has much of Alberta, because they are actual progressives, but we need to force the likes of Ford and Chow.
