Revised Stats Can data shows new housing supply, not fading demand, drove rent declines
A widely shared explanation for Canada's cooling rental market — that a retreat in population growth had reduced demand — has been substantially complicated by revised data from Statistics Canada.
An analysis by Rentals.ca of Statistics Canada's updated quarterly population estimates reveals that the country's population held up considerably better than earlier data indicated.
The cumulative upward revision to population, stretching back to Q4 2021, reached +301,008 as of Q2. What previously appeared as three consecutive quarters of population decline has been revised to show a single modest dip of 7,225 persons in Q4 2025.
The most dramatic single adjustment came in Q3 2025, where a previously reported decline of 76,068 persons was revised to a gain of 114,941.
Annual population growth from Q1 2025 to Q1 2026, earlier reported as -0.5%, has now been revised to +0.5%.
The driver was net non-permanent residents, adjusted upward by +275,942, representing more than 90% of the total revision. Statistics Canada attributes the correction to additional data from Immigration, Refugees and Citizenship Canada (IRCC) covering temporary residents with expired permits who remained in Canada while awaiting processing of permit extensions.
Under the previous methodology, these individuals were recorded as outflows at the moment their permit expired, regardless of whether they were still physically present in the country.
The implications for brokers and their investor clients are direct: demand did not collapse. Supply did the heavy lifting.
Why new supply deserves more credit
Average asking rents fell 7.6% from their May 2024 peak, according to Rentals.ca, a decline that unfolded even as population continued to grow at a modest pace. That combination points firmly to new apartment completions, rather than fading demand, as the central force reshaping rental affordability over the past year.
Canada Mortgage and Housing Corporation (CMHC) vacancy data supports that reading. Vacancy gains have been largest in the highest-priced unit quartile, where new construction has been concentrated.
Critically, all four rent price quartiles are now at multi-year vacancy highs, lending weight to the "filtering" concept, in which higher-priced new units are absorbed by higher-income households, freeing up more affordable stock further down the chain.
The supply pipeline and the risk ahead
The Rentals.ca analysis highlights a developing tension that brokers tracking the supply crunch risk ahead of 2028 will recognise. The economics of new construction have shifted against developers: softening rents, higher build costs, and tariff-driven pressure on materials have stalled condo starts and put new rental launches in doubt.
CMHC's MLI Select program has been credited with significantly expanding purpose-built rental construction in recent years. But Rentals.ca notes that many projects now completing were launched under more optimistic demand forecasts.
The policy environment — permitting timelines, zoning reform, tax relief, and construction financing — will need to support viable economics at current market rents if the gains from CMHC's record-setting rental construction activity are to continue into the next decade.
With population growth expected to recover as the temporary-resident adjustment cycle runs its course, and supply pipelines taking multiple years to move from project launch to completion, the affordability improvements of the past year could prove short-lived unless construction economics improve.
