Sadly, the NDP response to every issue is just another tax. Your kids are fat, put a tax on soft drinks, what ever happened to sending them outside.
Why not deal with the real problems in housing. The housing crisis is due to the systemic failure of a lot of government agencies and such. Fintrac, CRA, CBSA, the Realtors Association and the Legal profession all turning a blind eye to what was happening. Yes, many are government employees. Examples abound of illicit money in the market, bidding up homes and looking for a quick resale. Now governments at all levels find themselves in a bind. If the market crashes, and it will, how about the poor family that grossly overpaid for a half duplex in Abbotsford that finds themselves underwater. 
These taxes never generate the funds aspiring politicians think they will. Capital is mobile and will go where it is most wanted. 
The public should be asking tougher questions.
