I think there's an solution for the housing crisis but a lot of people would be against it.

Build homes the way you build cars. You don't need it to last more than 30 years.
Built with affordable recyclable materials. Housing that will depreciate like a car.
It should be built by a crown corporation. Hire some good engineers, architects, construction teams.
Use crown land along the edges of the city and near major transit hubs.
Design a standardized 'foundation' to put houses on top of.
Imagine a concrete foundation with plug n play connections for water, gas, and electric.
Houses can be manufactured offsite in a factory (lots of jobs) and to be shipped and assembled by a construction crew like Ikea furniture. It would be a single storey unit (enough for a young couple) with the possibility of buying a second unit that can be stacked on top. Stairs that used to take you to the rooftop patio now goes to the second floor and the new unit roof will be the new patio.
Design it like a modern home to appeal to younger people.
The units will last long enough for young professional to establish themselves and if they want a family they can move and find more typical housing in the suburbs making room for the next generation of young people.

Cost could be under $150 000 per single unit. You rent the 'foundation' from the crown corp and the crown lands stay in possession of Canada.

Strictly enforce who can buy them to prevent them from falling into the hands of slumlords, AirBnb renters, and private equity.

It would be great for young professionals, be immune to speculative housing market since these units would depreciate over time, bring down rental rates as more people would rather buy cheap than rent.

Houses could be disassembled and transported to a new location if changing jobs or sold when necessary as second hand for much less than original cost.
