Canada's Housing Shortage Holds at 3.5 Million Units: What the Stalled Figure Means for Your Investment
CMHC published its housing gap figure in September 2023 at 3.5 million units. Two years later, the number hasn't moved. That's not because the problem got solved. It's because construction stalled, population forecasts shifted, and the political math around immigration changed faster than anyone could build.
The gap was always an estimate. CMHC modeled household formation rates, vacancy thresholds, and affordability targets to arrive at what Canada needed by 2030 to meet decent housing conditions. The 3.5 million figure assumed population growth would continue at the pace set between 2016 and 2021, when the country added roughly 1.8 million people in five years. Immigration targets were climbing. Municipalities were rezoning. Developers were filing permits.
Then the pipeline choked. Municipal approvals slowed. Construction costs spiked. Developers shelved projects when financing at 6% made the pro forma impossible to close. The shortage didn't shrink because supply caught up. It held steady because demand stopped growing at the rate the model assumed.
What Changed Between 2023 and Now
Population growth is slowing. Statistics Canada's most recent estimates show net migration falling from the 2022 peak, and the federal government revised its immigration levels plan downward in 2024. Fewer people arriving means fewer households forming, which mechanically reduces the number of units needed to close the gap. The 3.5 million figure bakes in assumptions that no longer match the actual inflow.
At the same time, housing starts fell. CMHC reported 223,513 starts in 2023 (urban centres 10,000+), well short of the 280,000-per-year pace needed to meet the target. Multifamily construction, which was supposed to carry the load in urban centers, dropped hardest. Developers couldn't pencil out a 40-story condo tower in Toronto when construction loans were expensive and presale buyers were walking away from deposits.
The gap stayed at 3.5 million because demand moderated and supply undershot simultaneously. The net effect: the shortage neither grew nor shrank measurably.

A static shortage is not the same as a solved shortage. Vacancy rates in major markets vary widely, with some cities such as Calgary at 5% and Montreal at 2.2-2.9%, though other markets remain tight. Rent growth has cooled from the 2021-2022 spike, but it hasn't reversed. A landlord in Vancouver holding a condo bought in 2019 is still collecting rents 30% higher than five years ago, even if year-over-year growth is now single digits.
The risk is mistaking a plateau for a peak. If population growth restarts, either through a policy reversal or an economic recovery that pulls migrants back in, the gap widens again. And construction, once it stops, is slow to restart. A project shelved in 2024 doesn't come online in 2027 just because demand picks back up. There's a two-to-three-year lag between a developer's go decision and occupancy.
The other risk is regional divergence. The 3.5 million figure is national, but housing shortages don't work that way. Whitehorse doesn't help Toronto. A landlord in Calgary, where vacancy ticked up and starts outpaced absorption in 2025, faces different math than one in Ottawa, where vacancy rose to 3.5% by late 2025 on record new supply.
What You Should Do Differently
Stop assuming the national figure tells you anything about your specific market. CMHC's housing gap is a macro estimate. Your rental yield, your capital appreciation, and your refinancing options depend on what is happening in your postal code, in your building, on your street.
If you own in a market where construction has picked up and vacancy is rising, the plateau matters. Rent growth will compress. If you own in a market where nothing is getting built and population is still growing locally, the plateau is noise. You're still in a supply-constrained market with pricing power.
The figure held at 3.5 million because the assumptions changed, not because the problem went away. Build your investment decisions around what is actually happening in your building, on your block, in your city. The national number is for the headlines. Your cash flow is local.
