Number one, it's still a great goal. Continue to pursue it, but also use your voting capabilities at all three levels of government.
All three levels of government have a role to play in making housing more affordable and more accessible, and probably the place that Canadians focus on the least but has the most impact is actually municipally, especially for young Canadians looking for new types and new forms of housing. There are a lot of municipal things that get in the way, from zoning to bylaws to Nimbyism to anti-infill—all of those things.
Don't give up on the dream. Keep pursuing it, but be loud and active as well.
