## Market summary

Toronto's semi-detached inventory fell to 2.4 months in Q2 2026, a sharp tightening that contrasts with the city's overall 4.8-month supply. This divergence signals shifting leverage for buyers of attached homes in the broader Toronto market.

## Central finding

The strongest measured finding is a segment-specific supply squeeze in Toronto: semi-detached months of inventory dropped from 3.0 at the end of Q2 2025 to 2.4 at the end of Q2 2026, while condominium apartment inventory eased from 7.0 to 5.0 months over the same period. This indicates that demand for semi-detached homes is outpacing new listings more aggressively than for condos, creating a distinct price-pressure dynamic within the city's resale market. Sources:

## How the numbers connect

Calculates the year-over-year change in semi-detached months of inventory in Toronto. Calculation: (2.4 - 3.0) / 3.0 = -0.2 or -20% decrease in months of inventory from Q2 2025 to Q2 2026. Definitions: Months of inventory is the number of months it would take to sell current inventories at the current rate of sales activity. The geography is the City of Toronto, and the property type is semi-detached units. Limit: This calculation establishes a change between two specific quarter-end dates but does not establish a sustained trend, structural shift, or cause for the decline. Sources:

## Semi-Detached Supply Squeeze Diverges from Broader Market Balance

In the City of Toronto, the supply environment for semi-detached homes has tightened significantly, with months of inventory falling to 2.4 at the end of the second quarter of 2026 from 3.0 at the end of the second quarter of 2025. This represents a 20% reduction in available supply relative to sales velocity, placing the segment well below the balanced market threshold of 3 to 6 months. In contrast, condominium apartment inventory in Toronto declined more moderately from 7.0 to 5.0 months over the same period, suggesting that the pressure on attached home stock is more acute than on high-rise units. These figures are measured at the city level and do not constitute a measurement of the Corinthian neighbourhood specifically.

For buyers targeting semi-detached properties in the broader Toronto market, this inventory contraction implies reduced negotiating leverage compared to the condo segment. Sellers of semi-detached homes may find their listings absorbing faster, though median days on market for sold semi-detached units rose slightly to 15 days in Q2 2026 from 14 days in Q2 2025, indicating that the pace of absorption has not yet accelerated dramatically. The divergence between the 2.4-month semi-detached supply and the 4.8-month total city inventory highlights a compositional shift where attached homes are becoming scarcer relative to the overall market mix.

## Mortgage Renewal Wave Tests Affordability Limits

National financing conditions present a headwind for demand, as the final wave of pandemic-era five-year fixed-rate mortgages comes up for renewal. Approximately 12% of all outstanding Canadian mortgages will face an average 15% increase in monthly payments over the next year, according to Bank of Canada data cited by Royal LePage. This payment shock reduces household disposable income and borrowing capacity, potentially dampening entry-level demand across the country. While the Bank of Canada cut its key policy rate to 2.50% in September 2025, the cumulative effect of prior increases means that renewing borrowers face significantly higher costs than when they originally qualified.

The transmission of these national financing pressures to the local market is indirect. The mechanism operates through reduced affordability for existing homeowners who might otherwise trade up or for potential buyers whose purchasing power is constrained by higher debt service requirements. As of mid-2026, the Bank of Canada's policy rate has stayed near 2.25 percent, contributing to stable fixed mortgage rates after the sharp increases seen in 2022 and 2023, which provides some stability for new entrants but does not offset the renewal burden for those exiting low-rate terms.

## Condo Starts Plunge While Student Housing Pipeline Expands

New construction activity in Toronto shows a stark contrast between private condo development and institutional student housing. CMHC data indicates that only 156 new condo unit starts were recorded in the first half of 2026, signaling a severe constriction in new-purpose rental condo supply. This low start count suggests developers are cautious about entering the market given weak presale performance, such as the 33-35% presale rate reported for Yonge City Square before construction began in January 2025. Conversely, the Greater Toronto Area leads Ontario in student housing completions, with 2,734 beds projected for completion in 2026, representing 43% of the provincial total.

The composition of new supply is shifting toward larger units and institutional projects. Developers like Gupta Group have reduced unit counts on projects like Yonge City Square to increase the proportion of two- and three-bedroom residences, responding to demand for larger spaces. Meanwhile, the federal Build Communities Strong Fund, allocating $51 billion over 10 years starting in 2026-27, aims to support public infrastructure including housing, though specific allocations to residential projects depend on future selection. These delivery trends indicate that while private condo supply is shrinking, other segments of the housing market continue to see significant investment and completion activity. Sources:

## The strongest counter-case

While semi-detached inventory tightened, the overall Toronto market remains in buyer's territory with a sales-to-new-listings ratio of 42.1% and 4.8 months of total inventory as of September 2026. Furthermore, the MLS HPI composite benchmark for the GTA fell 4.5% year-over-year in August 2026, indicating that broad-based price declines are still occurring despite the segment-specific supply squeeze.

## The early signal

Months of inventory for semi-detached units in Toronto. How it reaches the market: A drop in months of inventory below the balanced threshold signals that sales are outpacing new listings, which typically exerts upward pressure on prices for that specific property type as competition among buyers intensifies for limited stock. Typical lead time: Inventory levels typically lead price changes by one to two quarters, as sellers adjust asking prices in response to observed absorption rates and competing offers. Sources:
[Toronto Market Conditions | CREA Statistics](https://stats.crea.ca/mls/treb-market-conditions)

## Next 3 months, through December 2026

Prices: flat. Stable pricing in the broader Toronto market, with potential slight softening due to seasonal slowdown. This is not a measured Corinthian result. Why: The overall Toronto market remains in buyer's territory with a 42.1% sales-to-new-listings ratio and 4.8 months of inventory as of September 2026. Seasonal factors typically reduce activity in Q4, supporting flat price movement in the parent geography. Buyers: wait. Waiting allows buyers to observe if the semi-detached inventory tightness persists into winter, potentially offering better negotiation opportunities if supply does not recover. Sellers: either way. Sellers can list now to benefit from the tighter semi-detached supply, or wait for spring if they prefer higher visibility, as the current balance supports reasonable absorption. Watch: A rise in semi-detached months of inventory above 3.0 would signal a return to balanced conditions, reducing seller leverage. Confidence: moderate. Sources:

## Next 6 months, through March 2027

Prices: rising. Modest price appreciation in the broader Toronto semi-detached segment as spring market activity begins. This is not a measured Corinthian result. Why: The 2.4-month inventory level for semi-detached homes in Toronto suggests underlying demand strength that may translate to price gains as the spring selling season ramps up. However, national mortgage renewal pressures could cap the magnitude of any increase. Buyers: buy now. Acting now secures a purchase before anticipated spring price increases driven by low inventory and renewed demand, avoiding paying a premium later. Sellers: list now. Listing now positions the home to capture early spring demand, leveraging the tight inventory to attract multiple offers and potentially exceed asking price. Watch: A further decline in sales volume or a rise in total inventory would indicate weakening demand, negating the expected price rise. Confidence: low. Sources:

## Next 12 months, through September 2027

Prices: flat. Prices likely to stabilize in the broader Toronto market as new supply deliveries and financing costs reach equilibrium. This is not a measured Corinthian result. Why: The combination of low condo starts (156 in H1 2026) and ongoing student housing completions suggests a mixed supply outlook. National funding initiatives like the Build Communities Strong Fund may support long-term stability, but immediate price momentum is tempered by affordability constraints. Buyers: either way. Buyers can act either now or later, as the 12-month horizon suggests a stabilizing market where timing differences in price are likely to be minimal. Sellers: either way. Sellers have flexibility in timing, as the market is expected to remain balanced, allowing them to choose listing dates based on personal circumstances rather than urgent market pressure. Watch: Significant new condo completions or a major interest rate hike would shift the market back to buyer's territory, altering the flat price expectation. Confidence: low. Sources:

Assumptions: No major changes to national monetary policy beyond the current trajectory of stable rates near 2.25-2.50%; Continued execution of federal housing infrastructure funds without significant delays in project approval; Seasonal patterns in housing demand remain consistent with historical norms. What would reverse this: A sudden spike in mortgage delinquencies or a rapid increase in interest rates could accelerate price declines, overriding the supply-side tightening effects. Sources:
