I think it's not just the Liberals, but the Conservatives that are at fault. Neither parties have done much of anything when they were in power to help this and other significant stagnation issues over the least two or three decades.

At least for Toronto, the federal and provincial governments had to be punched in the sides to make public transit investments after being forgotten for most of a half century, and even then the new constructions are still quite inadequate and will require at least two more decades of consistent work before things reach a decent level, presuming that other areas don't get worse in the meantime.

It's unfair to just blame the Liberals. All our leading parties suck because they see themselves as invulnerable. They've gotten used to being an oligarchy, and the NPD is no longer scaring them, but instead have become a part of the oligarchy. Layton was great, Mulcair was okay, but Singh is just a puppy following Trudeau. Without someone new (it can be the Rhinoceros Party for all I care) getting a decent number of seats to become a legitimate threat to the oligarchy and make them actually move their asses for real and positive change, I think we're stuck with nothing but corrupt personal interests.

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.

It is a fundamental issue with the way we have been building and running the urban and economic fabric of our cities. Car centric design and infinite growth housing goals have pushed our cities into debt building sprawling suburbia. The economy also shifted away from manufacturing and production towards more service industries that support suburbia and add less value to the overall economy. Canadians have been spending more on necessities while making less in wages and part of this is influenced by the financially unstable ways we build our cities, the reliance on automobiles, and a less productive per capita economy.

They don't want to bring the prices down because they've made their own wealth and that of other wealthy property owners, and a good chunk of Canada's economy, dependent on the prices staying high. So they have to pay lip service and make statements about how they want to make housing affordable without actually, you know, bringing the prices down.

Or rent.

I had to move from my apartment to a rooming house. Next is the street. :(

Supply and demand are key factors in pricing. If no one wanted to buy houses, prices would go down. Of course, people foolishly want to live in dwellings rather than under bridges, so there will always be some amount of demand. Therefore, increasing the number of dwellings will have an impact on both rental prices and house prices. People can still charge whatever they want for their house, but if there is something more desirable for a lower price, it isn't going to sell. Likewise for rental properties, landlords want to make as much as possible, but vacant units bring in less money than units with reduced prices. Again, that only matters when there is a sufficient supply of residences for the population.
