Construction labour in Canada is near 100% utilization in Canada.

True but there are other ways to spend money that doesn’t involve having more construction happening at once. For example, buying land to be used for non-market housing. This one taken seriously would dry up the whole 73B already. Buy already built properties, give more financial incentives for multi-family housing, etc. There’s a long list of things of expensive solutions waiting.

Send that money to provinces tied to strict usage rules towards transit oriented development and non-market housing. For example, Translink needs funding and expanding mass transit is one way to improve the housing crisis.
