Waterdown: Hamilton's 45% Sales Ratio and 3.9% HPI Drop Define a Balanced Market

Key facts and reporting periods

Market summary

The Hamilton Region recorded a 45% sales-to-new-listings ratio in September 2026, placing the market at the threshold between seller and buyer dynamics. This balance is accompanied by a 19.35% year-over-year decline in new listings and a 3.9% drop in the MLS Home Price Index.

Central finding

Hamilton's market has shifted to balanced conditions with a 45% sales-to-new-listings ratio and a 3.9% year-over-year decline in the MLS Home Price Index. The contraction in new listings (down 19.35%) suggests sellers are holding back, which may stabilize prices despite softening demand.

Balanced Conditions Mask Underlying Price Softening

The Hamilton Region entered September 2026 with a sales-to-new-listings ratio of 45%, a metric that typically defines a balanced market where neither buyers nor sellers hold significant leverage. This equilibrium is supported by 4.5 months of supply and an average of 43 days on market, figures that suggest a stable but cautious environment. However, these balance indicators coexist with a 3.9% year-over-year decline in the MLS Home Price Index, indicating that while transaction volume is steady, the value of those transactions is eroding.

New listings in Hamilton fell 19.35% year-over-year to 546 units, a sharp contraction that may be preventing a deeper price slide. This reduction in supply contrasts with the 6 months of inventory reported for August, which some analysts classify as a buyer's market. For residents in Waterdown, this divergence means that while the broader city shows signs of stabilization, the underlying price pressure remains a critical factor for any transaction.

Mortgage Renewals and Rate Stability Shape Borrower Capacity

The Bank of Canada held its policy rate at 2.25% in July 2026, keeping lenders' prime rate at 4.45% and leaving variable mortgage payments unchanged for existing borrowers. Despite this stability, rising five-year Government of Canada bond yields near 3.65% are exerting upward pressure on fixed rates, with the lowest available five-year fixed rate reaching 4.24% as of September 18, 2026. These financing conditions create a complex landscape where variable-rate holders enjoy stability, but those renewing fixed-term mortgages face higher costs.

Borrowers renewing pandemic-era five-year fixed-rate mortgages can expect an average 15% increase in monthly payments, affecting approximately 12% of all outstanding Canadian mortgages over the next year. This renewal wave represents a significant headwind for affordability, potentially dampening demand as households adjust to higher debt service. In Hamilton, where the median household income is $103,831, these increased payment obligations may limit the pool of qualified buyers, particularly in the entry-level segment.

Federal Infrastructure Funds Target Housing-Enabling Projects

The Canada Housing Infrastructure Fund (CHIF), established with $6 billion in federal funding over 10 years, aims to accelerate the construction and upgrading of housing-enabling water, wastewater, stormwater, and solid waste infrastructure. To qualify for CHIF funding, communities with populations over 30,000 must implement zoning changes allowing four units as-of-right. This requirement directly impacts municipalities like Hamilton, which must align their local planning frameworks with federal conditions to access capital for essential infrastructure upgrades.

Additionally, the Build Communities Strong Fund will provide $51 billion over 10 years starting in 2026-27, plus $3 billion annually ongoing, for public infrastructure including housing. These federal initiatives signal a long-term commitment to addressing housing supply constraints through improved community amenities and transit links. While the direct impact on private housing supply is mediated by municipal planning decisions, the availability of such funds may support higher-density development patterns and improve overall housing affordability in the region.

Local Policy Alignment and Municipal Housing Targets

A new report from the University of Ottawa found that Toronto is falling “well short” of its housing targets along with 22 of the 34 other municipalities in the Greater Golden Horseshoe. This finding underscores the challenges faced by municipalities in meeting provincial housing goals, a context that likely applies to Hamilton as well. The gap between target and actual delivery highlights the need for more aggressive policy measures and efficient use of available funding streams to close the supply deficit.

In Hamilton, the population has surpassed 575,000 in 2025, driven by relatively lower home prices compared to the GTA and ongoing downtown revitalization. This growth places additional pressure on the housing market to absorb new residents, further emphasizing the importance of both public and private sector efforts to increase housing supply. For Waterdown, this regional dynamic suggests that local planning decisions will play a crucial role in determining how effectively the neighbourhood can accommodate growth while maintaining its character.

The strongest counter-case

While the sales-to-new-listings ratio indicates balance, the 6 months of inventory reported by Wahi for August 2026 characterizes the market as a buyer's market. Additionally, the LJM Tower creditor protection event in Hamilton signals ongoing risk in the condo sector, which could dampen broader confidence.

The early signal

Monitor the following measure: Sales to New Listings Ratio. How it reaches the market: The sales-to-new-listings ratio moves before headline price indices because it reflects real-time buyer interest relative to available supply. A shift in this ratio often precedes changes in the MLS Home Price Index, providing an early warning of market direction. Typical lead time: 1-2 months ahead of the MLS Home Price Index.

Next 3 months, Through December 2026

Prices: flat. 0% to -1% for all property types in Hamilton; not a measured Waterdown result. Why: The 45% sales-to-new-listings ratio and 4.5 months of supply suggest balance, but the 3.9% HPI decline indicates underlying softness. Mortgage renewal pressures may limit demand growth. Buyers: wait. Waiting allows buyers to benefit from potential further price adjustments as mortgage renewals impact affordability. Sellers: list now. Sellers should act now to capitalize on the current balance before potential demand declines from mortgage renewals. Watch: A sustained drop in the sales-to-new-listings ratio below 40% would indicate a shift to a buyer's market. Confidence: moderate.

Next 6 months, Through March 2027

Prices: falling. -1% to -3% for all property types in Hamilton; not a measured Waterdown result. Why: The 15% increase in mortgage payments for renewing borrowers is expected to reduce demand, potentially leading to further price declines. The 19.35% drop in new listings may not be enough to offset this demand weakness. Buyers: buy now. Buyers may find better pricing opportunities as demand softens due to mortgage renewal pressures. Sellers: wait. Sellers may face more competition and lower offers if demand continues to weaken. Watch: An increase in new listings above 600 units per month would suggest a return to seller-friendly conditions. Confidence: low.

Next 12 months, Through September 2027

Prices: rising. +1% to +3% for all property types in Hamilton; not a measured Waterdown result. Why: Federal infrastructure funds and potential rate cuts could stimulate demand and support price recovery. The long-term commitment to housing supply through CHIF and Build Communities Strong Fund may improve affordability and attract buyers. Buyers: either way. Buyers have flexibility depending on whether they prioritize current pricing or potential future appreciation. Sellers: either way. Sellers can choose to list now or wait for potential price increases driven by improved market conditions. Watch: A significant increase in housing starts or completions in Hamilton would indicate a stronger supply response, potentially limiting price gains. Confidence: low.

Assumptions: The Bank of Canada maintains its current policy rate stance through 2026; Federal infrastructure funds are allocated to Hamilton as planned; No major economic shocks occur that significantly impact housing demand. What would reverse this: A sudden increase in interest rates or a negative economic shock could accelerate price declines and extend the buyer's market conditions.
