Not that I agree at all with increasing the inclusion rate, but it's worth considering how the present cost of real estate in some of Canada's major centres is already resulting in human outflows, reducing the future tax base, and creating life-altering debt levels. 

Given the frightening importance of real estate/construction to the economic health of places like BC (and, increasingly it would seem, Ontario), properly addressing that mess would be FAR more impactful on GDP, individual net worth, and job creation. 

What I'm saying is: if you're an older land owning Canadian (i.e. a primary beneficiary of the policy-driven real estate gains we've seen) it's probably worth being thankful that the government is unlikely to be taking meaningful action to change the special treatment and interventions on behalf of real estate.
