Key Takeaways
- Toronto’s Census Metropolitan Area (CMA) experienced its first recorded population decline outside of the pandemic, losing about 1,000 residents in the year ending July 1 2025.
- The drop reversed a massive gain of nearly 270,000 people the previous year, pushing Toronto from first to 412nd place among 435 Canadian and U.S. metropolitan areas in growth rankings.
- Although net international migration remained relatively strong (≈53,000 newcomers), it fell 84 % compared with 2024, exposing a deeper domestic out‑migration problem.
- Toronto lost roughly 77,500 more residents to other parts of Ontario and Canada than it gained through domestic migration in 2025, driven largely by unaffordable housing.
- The population slowdown is contributing to higher rental vacancy rates, a weakening condo market, and mounting fiscal pressures for the city.
- Calgary and Edmonton were the only Canadian cities to break into the top‑10 fastest‑growing list, highlighting a broader national trend of moderating growth.
- Researchers warn that without addressing housing affordability and retaining domestic migrants, Toronto’s fiscal health and economic competitiveness could deteriorate further.
Population Decline Overview
Toronto’s CMA, which includes the City of Toronto and its surrounding municipalities, recorded a net loss of approximately 1,000 people between July 1 2024 and July 1 2025. This marks the first annual decline for the region since Statistics Canada began tracking such data, excluding the anomalous pandemic years of 2020‑2021. The figure represents a stark reversal from the previous 12‑month period, during which the CMA gained nearly 270,000 residents—a surge that had propelled Toronto to the top of North American growth rankings. The sudden shift underscores how quickly demographic momentum can change when underlying drivers such as immigration flows and domestic migration patterns are disrupted.
Immigration Trends and the International Migration Slowdown
Despite the overall population loss, Toronto continued to attract a substantial number of new immigrants, adding about 53,000 people through net international migration in 2025. However, this figure represents an 84 % decline compared with the 2024 inflow, which had exceeded 300,000 newcomers. The drop aligns with federal policy changes that tightened restrictions on temporary foreign workers and international students, reducing the pipeline of temporary residents who often transition to permanent status. While international migration remains a positive contributor, its sharp contraction removed a key buffer that had previously offset losses from other migration streams.
Domestic Out‑Migration: The Core Challenge
The primary driver of Toronto’s population decline is a pronounced exodus of residents to other parts of Ontario and Canada. In 2025, the city experienced a net domestic migration loss of roughly 77,500 people—meaning far more individuals left the CMA than arrived from elsewhere in the country. Researchers Diana Petramala and Frank Clayton note that this out‑migration reflects growing dissatisfaction with the cost of living, particularly housing affordability. Many households, unable to find suitable or reasonably priced accommodation, are relocating to smaller cities, suburban areas, or regions with lower living costs, thereby eroding Toronto’s resident base.
Housing Affordability as a Push Factor
Toronto’s housing market has long been characterized by high prices and limited supply, a dynamic that intensified through 2024‑2025. Rising mortgage rates, constrained new‑home construction, and speculative investment have pushed both rental and ownership costs beyond the reach of many middle‑ and lower‑income families. As a result, even those who secure employment in the city often find it financially untenable to stay long‑term. The affordability crisis not only fuels out‑migration but also discourages prospective in‑migrants from choosing Toronto as a destination, creating a feedback loop that hampers population growth.
Impact on Rental Vacancies and the Condo Market
The population slowdown has begun to manifest in tangible market signals. Rental vacancy rates in Toronto have climbed as new supply hits the market while demand weakens, a trend highlighted by recent reports from real‑estate analysts. Higher vacancies put downward pressure on rents, potentially benefiting tenants but squeezing landlords’ revenues and discouraging further investment in rental construction. Simultaneously, the condo market—once a robust engine of growth—shows signs of strain, with unsold inventory lengthening and price growth stagnating. These dynamics threaten the city’s property‑tax base, which relies heavily on residential assessments.
Fiscal Implications for the City
A shrinking population directly affects municipal finances. Fewer residents mean reduced revenue from property taxes, transit fares, and user‑fee‑based services, while fixed costs such as infrastructure maintenance and public‑sector salaries remain relatively constant. The outflow of higher‑earning households can also diminish income‑tax‑linked transfers from provincial and federal governments. Analysts warn that if the demographic trend persists, Toronto may face widening budget gaps, necessitating difficult choices between service cuts, tax increases, or increased borrowing—each of which carries its own economic and social risks.
Comparative North American Context
When placed alongside other metropolitan areas, Toronto’s fall is striking. The TMU‑CURB analysis of 435 Canadian and U.S. CMAs showed the city dropping from first place to 412nd in annual growth ranking—a decline of over 400 positions in a single year. Only Calgary and Edmonton managed to retain spots in the top‑10 fastest‑growing Canadian cities, reflecting a broader moderation of growth across the nation. The contrast highlights that while some Canadian metros continue to attract domestic migrants—often due to more affordable housing or expanding job markets—Toronto’s combination of high costs and out‑migration is unique among major urban centers.
Policy Responses and Future Outlook
Addressing Toronto’s demographic reversal will require a multifaceted approach. Policymakers could accelerate housing supply through streamlined approvals, incentives for purpose‑built rentals, and measures to curb speculative vacancy. Simultaneously, enhancing transit connectivity to more affordable suburbs might retain workers who currently leave for lower‑cost regions. Retention strategies—such as targeted subsidies for first‑time buyers, rent‑control adjustments, or workforce‑development programs tied to local employment—could mitigate domestic out‑migration. Finally, maintaining a welcoming stance toward immigrants, while adjusting for federal policy shifts, will remain crucial to sustaining net international inflows. Without decisive action, the city risks prolonged fiscal strain and a diminished role as Canada’s premier economic hub.
