Truthfully I don't think this is an issue the federal government is in a position to solve any time soon. The long and short is that our population has grown faster than our supply of housing, COVID being an unfortunately timed disruption which further strained that supply. Nothing was built for almost a year, but the population continued to grow.
If I had a singular policy suggestion, after having talked to some friends in the industry, it would be to pump federal money into expediting site plan approvals and environmental assessments done at a county or municipal level. Some of these offices have tiny rosters who end up being the bottlenecks for enormous projects which otherwise would be breaking ground. Environmental assessments are notoriously time-consuming and particular in Canada, something we're largely very proud of. That said, I believe if there were ever a time for Canadians to be okay with cutting corners if it meant getting more of us into homes, I think it would be now. From my understanding, there are many housing projects in Ontario for which construction could begin next week, if not for the Sisyphean approval processes.
Here's an example of a site plan approval process for a town in Ontario[2] - just imagine all the points in which that chain of communication can get gummed up and projects can sit idle. We're used to steps like this taking a couple weeks in tech, but in the land development industry things move s l o w.
Canadians often take pride in our ability to do things the way they're meant to be done and to follow the rules as presented, even when they might not make sense in the moment. I think occasionally our love of process can be our downfall.
