The Ontario housing market is undergoing one of its most significant structural resets in over a decade. For years, the story of real estate across Southwestern Ontario—and specifically within the City of London—was defined by hyper-competition, severe supply deficits, and staggering price acceleration. However, macroeconomic shifts, persistent borrowing costs, and a major influx of housing supply have fundamentally altered the landscape.
According to data from the Canadian Real Estate Association (CREA) and the London and St. Thomas Association of REALTORS® (LSTAR), a clear divergence has emerged between raw market classifications and seasonal transactional behavior.
To determine whether London, Ontario is officially a buyer’s market, we must analyze the exact empirical thresholds that define market balance: Months of Inventory (MOI) and the Sales-to-New-Listings Ratio (SNLR).
Defining the Threshold: The Metrics of a Buyer’s Market
In real estate analytics, market types are not determined by emotion, but by mathematical ratios that track supply absorption. CREA classifies market balance using the Sales-to-New-Listings Ratio (SNLR):
- Sellers’ Market: SNLR above 55%
- Balanced Market: SNLR between 45% and 55%
- Buyers’ Market: SNLR below 45%
When analyzing local LSTAR data, the shift toward a buyer-favorable climate becomes immediately apparent. In early spring, the regional SNLR hit 36.0%, directly positioning the market deep within buyer territory. While late spring and early summer data showed a minor seasonal rebound—with the SNLR adjusting to 42.8%—it remains firmly under the 45% threshold.

Simultaneously, Months of Inventory (MOI)—the time it would take to completely exhaust current listings at the active pace of sales—has hovered between 4.3 and 5.0 months. Historically, anything over 4 months of inventory signals a market normalizing toward buyers, giving them the luxury of time, choice, and leverage that did not exist during the pandemic-era boom.
The Divergence by Housing Segment
While the macro metrics point toward a buyer’s market, the reality on the ground is highly segmented. A blanket classification does not accurately reflect how different property types are behaving in the London area.
| Housing Segment | Average/Median Price Trends | Active Inventory Status | Market Behavior |
| Single-Family Detached | Average: ~$662,292 | ~4.1 Months of Supply | Relatively stable; well-priced detached homes under $600k still attract steady, selective demand. |
| Townhouses & Row Units | Average: ~$479,810 | ~6.5 Months of Supply | Buyers’ market. High relative inventory gives buyers immense negotiating leverage on terms. |
| Apartment Condominiums | Average: ~$297,458 | ~7.2 Months of Supply | Deep buyers’ market. Highest first-quarter inventory levels recorded in over a decade; extended days on market. |
As outlined above, the high-density segments (condos and townhouses) are facing severe supply absorption friction. With months of inventory for apartments stretching past 7 months and average prices softening year-over-year, this segment represents the truest iteration of a buyer’s market in London.
Conversely, single-family detached homes sit in a more balanced, transitionary zone. While inventory has grown to over 4 months, a steady monthly uptick in transactional volume has prevented a total downward price spiral, even causing a modest seasonal bump in the overall regional average price to $662,292 during peak spring activity.
Key Drivers Behind London’s Housing Inventory Surge
This massive influx of active inventory—which reached thousands of active listings concurrently on the MLS system—is driven by three distinct economic forces:
1. The Mortgage Renewal Cliff
A significant percentage of homeowners who purchased or refinanced during the historic low-rate environment of 2020 and 2021 are facing mortgage renewals at drastically higher fixed and variable percentages. For some, the increased carrying costs have triggered defensive listings, adding steady secondary inventory to the local market.
2. Sidelined Buyer Psychology
Even with minor adjustments from the Bank of Canada, the cost of borrowing remains high relative to median household incomes in Southwestern Ontario. Buyers are no longer acting out of urgency or FOMO (Fear Of Missing Out). Instead, they are content to wait on the sidelines, stretching the median Days on Market (DOM) to roughly 24 to 26 days across the region.
3. The Slowdown of the GTA Migration Effect
During the peak of remote work trends, an unprecedented influx of buyers migrated from Toronto and the Greater Toronto Area (GTA) into London, driving up demand. As corporate return-to-office mandates normalized and capital became more expensive, this outward migration slowed down, allowing local London inventory to accumulate rather than being immediately absorbed by out-of-market capital.
What Current Inventory Levels Mean for Your Next Move
Whether you are looking to purchase your first home, downsize, or liquidate an investment property in London, St. Thomas, or the surrounding Middlesex County, this high-inventory environment requires highly specific strategies.
For Real Estate Buyers: Negotiation Power is Back
If you are buying in the current market, the paradigm has completely flipped.
- Reintroduce Conditions: The days of waving home inspections and financing clauses are largely gone. Buyers can—and should—protect themselves with conditional offers without fear of being automatically rejected.
- Price Discovery: With a Sale-to-List Price Ratio averaging 97.4%, homes are routinely trading below their original list price. Look for listings that have surpassed 30 days on market, as these sellers are often the most amenable to price corrections or closing cost credits.
- Target High-Inventory Pockets: Investors and first-time buyers looking for entry-level pricing should look closely at the condo and townhouse segments in London North and South, where inventory accumulation is highest.
For Real Estate Sellers: Strategy Over Speed
Selling a home in a 5-month inventory market requires an aggressive departure from past expectations.
- Accurate Pricing from Day One: In a buyers’ market, overpricing a home is a fatal strategic error. A property that sits on the MLS past the critical 21-day mark quickly becomes “stale” in the eyes of buyers, eventually forcing a deeper price drop than a correct initial valuation would have required.
- Expect a Longer Timeline: Sellers must plan for a realistic marketing period. Homes are taking significantly longer to sell than a year ago. Prepare your moving timelines and bridge financing options accordingly.
- Condition and Presentation: Because buyers have hundreds of options to choose from, properties that are poorly staged, deferred on maintenance, or inadequately photographed will simply be ignored. Professional staging and strategic digital marketing are mandatory to stand out in a crowded market.
Conclusion: A Normalizing, Healthier Ecosystem
Is London, Ontario officially a buyer’s market? By structural metrics like the Sales-to-New-Listings ratio and high inventory markers in the condo and townhouse spaces, yes—the balance of power firmly favors the buyer.
However, it is more accurately described as a healthy normalization. The current climate represents a transition away from extreme volatility and toward a predictable, rational real estate ecosystem. Prices have established a steady baseline, inventory offers genuine choice, and both sides of a transaction can finally negotiate with transparency and deliberation.
