In any policy void,  Canadian governments resort to more taxation.  Capital gains tax on real estate investment shows a lack of understanding of rational markets, especially the development of critical housing stock called rentals.  The root issue is supply of detached homes.  Not the supply of condo's.  The homes people crave are made difficult to build by a mountain of provincial regulations.  Recognize the market shortcoming,  open it up and let it work.  Stop resorting to capital gains tax, mortgage approval criteria, elevated CMHC hurdles etc.   The solution is not more government intervention.
