There's the inconvenient fact that housing is way more provincial and municipal than federal. The feds can't (and shouldn't) be able to tell a town/city what they can or can't do as per the rules of our democracy.

That being said, the Feds should be building their own public/rent geared to income housing.

One of the biggest hurdles is NIMBY voters who alway turn up and vote against density and constantly jam the system regardless of need - and those who need affordable housing generally don't show up to vote.

If the feds build their own housing, or blast provincial/local governments who are preventing the proliferation of Federally funded housing the narrative should hopefully flip.

Currently its the spider-man meme of feds, premiers, and municipal governments pointing at each other as the source of housing inequality - and all of them are correct. But it's lack of public understanding that allows the inaction to continue.

This isn't something that needs to be profitable, it's fulfilling the basic role of government working for the people and giving them value.

This would also put pressure on developers collectively refusing to build due to costs. If you're not developing, the land moves to the feds to be developed instead.

Some things need to exist outside of profit seeking.
