Unless gov't allows more housing to be built, these measures, vacant house tax, foreign buyer tax, won't make any difference to house prices.  

If Canada is going to continue to accept 250-300k immigration per year, they gotta live somewhere and if supply of new homes is lagging demand then, and it ain't rocket science, prices will rise.  Now if there was an excess of supply, then prices would moderate or depending on the oversupply, actually decline.

But since gov't shows no interest in increasing supply, nor in reducing demand, then we will all be in the same boat next year only with higher home prices but perhaps a few less sales.  What's not to love?  A gov't policy that brings in money but accomplishes nothing.
