Real Estate in Canada is interesting. We invest way more of our wealth in it than Americans, yet many can't afford to get started with their first purchase. Somehow the government needs to get more people into houses without destroying the nominal value (i.e. triggering big price decreases). I suspect they'll focus on supply and programs to help people pay the high list prices, but not try and control what a home costs directly. Inflation can then solve some of the real volume problem, but with a lot of knock-on impacts and also push it down the road. Tough scenario to try and address...
I think this would be fine if the government was willing to eat some cost of mortgage adjustments. The biggest problem with price decreases in what I believe to be in the way you mean - that existing home owners see their values drop - is one the mortgage is underwater you have an upside down situation for both the owner and the bank.
One way to offset this is if the government eats the difference in some way. I don't exactly know how this would be structured, but if this were to be the case, I imagine it would go a long way to getting more people on board with housing reform.
It shouldn't have ever been treated like a store of wealth to begin with. You're either the homeowner or the landlord, this middle path of being both your own homeowner and effectively treating it as a store of wealth - there by in a sense making you your own landlord if you will - is the problem.
