Recent data from the City of Toronto indicates that there were approximately 106,000 new residential units completed between 2019 and 2023. That averages to about 26,500 homes per year.

At the same time, Toronto is reporting that 258,397 units are currently approved for development and that 436,421 units are currently under review. The former means that the projects have been approved and that a building permit has been applied for or has been issued. And the latter means that the units are still under review or under appeal.

These feel like staggering numbers. If we were to use the same completion rate as 2019-2023, it would take over 26 years to build these 694,818 new units (homes approved + under review).

However, I think it's safe to assume that not all of these homes will be built; at least not in the short term. Many (perhaps most) of these projects are simply going to evaporate in the current market environment. They're unfinanceable.

Because that's the thing, zoning approved does not necessarily equal built and occupied. And right now, in this market, these two things feel like they're diverging. Toronto grew by about 207,000 people between 2019 and 2023. And it built about half of this number in new homes.

When we look back at the next four years, I suspect that this housing supply number will be noticeably lower. This is despite the staggering headline numbers.
