Canada’s housing debate usually starts with prices. We think it should start with arithmetic. The average Canadian household holds about 2.4 people (2021 Census). So for every 2.4 people the country adds, it needs roughly one more home, before counting the homes we already lacked.
Canada Mortgage and Housing Corporation (CMHC) counts every home that breaks ground each month. Statistics Canada estimates the population every quarter. Put them side by side and the story of the last four years is hard to miss.
Housing starts, Canada
Annual starts, all areas. CMHC estimates Canada needs 430,000 to 480,000 a year through 2035 to restore affordability.
Five people for every home
In 2022 Canada grew by 1,050,110 people. In 2023 it grew by 1,271,872, a 3.2% jump and the fastest rate since 1957. Most of that came from temporary residents: international students, temporary foreign workers and asylum claimants. Housing starts actually fell that year.
Divide population growth by housing starts and you get the number of new residents per home started. A sustainable ratio sits near household size. In 2023 it was more than double that.
New residents per housing start
Calendar-year population change divided by housing starts. The dashed line is average household size.

| Year | Population change | Housing starts | Residents per start |
|---|---|---|---|
| 2022 | +1,050,110 | 261,849 | 4.0 |
| 2023 | +1,271,872 | 240,267 | 5.3 |
| 2024 | ≈ +750,000 | 245,367 | 3.1 |
| 2025 | ≈ −102,000 (prelim.) | 259,028 | −0.4 |
At 259,000 starts a year and 2.4 people per home, housing construction supports about 620,000 new residents a year. In 2023 Canada added twice that.
What happened when growth slowed
Ottawa cut temporary resident intake in 2024 and 2025. The number of non-permanent residents fell by a record 176,479 in the third quarter of 2025, and the population shrank, its first quarterly decline since the pandemic. Rental markets responded fast.
Purpose-built rental vacancy rate, Canada
Share of purpose-built rental apartments sitting empty in October each year. Around 3% is considered a balanced market.
That is the whole argument in one chart. When population growth matched what we could build, the pressure eased. Vacancy in Vancouver reached 3.7%, its highest since 1988. Toronto hit 3% for the first time since the pandemic.
The lesson is not that Canada should stop growing. It is that growth and building have to move together. The right answer is to build faster and set immigration levels against what we actually build.
What we’re asking for
- Publish a single annual target for total population growth, permanent and temporary, alongside CMHC’s housing projections.
- Keep new residents per housing start within a band around household size, and report it every quarter.
- Give construction trades priority in economic selection so immigration helps close the gap it can otherwise widen.
How this is measured
Housing starts count units where construction has begun (foundation poured), from CMHC’s monthly survey. Starts lead completions by one to three years, so they show what supply is coming, not what has arrived.
Population change is Statistics Canada’s January-to-January estimate, including permanent and non-permanent residents. Estimates are revised; 2024 and 2025 figures here are rounded and the 2025 figure is preliminary.
Limits: the ratio ignores demolitions, household size shifts and regional mismatch. It is a pressure gauge, not a forecast.
