Your solution focusing on increasing the supply of single family homes is questionable. Single family homes are incapable of supporting affordable housing markets in high demand areas like Toronto, Quebec, Ontario, and Vancouver, which are where most Canadians live. North America needs more flexibility and capital to support upzoning the housing supply we already have from the overused SFH to missing middle multiplexes, or from those to low rise apartments, or from those to 5 over 1 style buildings, or from those to towers. The rigid Euclidean zoning policies of North America mean that even if all housing stock was privately owned by residents, there would still be a shortage in the high demand places where most people live, leading to continued high prices. Especially because we have so much trouble building quality public transit that would open up more land as desirable for development. High speed rail between Windsor and Quebec City could spread out the demand to existing supply in smaller low-cost cities while providing a boon to those cities' economies, but Via Rail has pretty definitively shut that down in favor of HFR at this point for cost reasons
