Rising Commercial Operating Costs in Eastern Ontario: What Property Owners and Brokers Need to Know 📊
A multi-unit commercial building owner in Kingston, Ontario just received their 2026 mid-year utility reconciliation and discovered heating and cooling costs jumped 14% compared to the same period last year. That increase, combined with insurance premiums that rose 9%, has eroded net operating income by nearly $30,000 on a single property. This scenario is playing out across Eastern Ontario, and it has real consequences for property values, refinancing capacity, and investment returns.
What Is Happening With Commercial Operating Costs in Eastern Ontario? 📍
Commercial operating costs across Eastern Ontario, Ontario have increased 8-12% year over year as of mid-2026, driven primarily by utility rate hikes, insurance premium escalation, and rising property management labour costs, according to BOMA's latest national benchmarking data. Operating costs (sometimes called operating expenses or OPEX) represent the recurring expenditures required to maintain and run a commercial property, including utilities, insurance, property taxes, maintenance, and management fees. These costs are subtracted from gross revenue to calculate net operating income (NOI), which is the foundation of income-based commercial real estate appraisal.
"As of Q2 2026, Eastern Ontario commercial properties are experiencing operating cost increases of 8-12% year over year, with Class B and C office buildings and older multi-unit retail properties absorbing the largest proportional increases due to less energy-efficient building envelopes."
The impact is not uniform across property types. Industrial properties with triple-net lease structures pass most operating costs through to tenants, insulating owners from direct NOI compression. But owners of office buildings and older retail properties on gross or modified gross leases are absorbing these increases directly. For a typical 20,000-square-foot office building in Eastern Ontario generating $400,000 in gross revenue, a 10% rise in operating costs translates to roughly $18,000 to $22,000 in lost NOI annually.
What Should Property Owners in Eastern Ontario Do Now? 🏢
Property owners should order a current commercial real estate appraisal before the end of Q3 2026 to establish a defensible baseline value while NOI compression is still manageable and before lenders tighten underwriting further. In our experience working with property owners across Eastern Ontario, those who act proactively secure better refinancing terms than those who wait for costs to stabilize. The reality is that operating costs rarely reverse quickly once they climb.
Owners considering mortgage refinancing appraisals should factor in these practical steps:
- Review all lease structures immediately. Properties on gross leases should be transitioned to modified gross or triple-net structures at renewal to shift future cost increases to tenants. According to Altus Group's Q1 2026 report, landlords in Eastern Ontario who converted to net lease structures retained 6-8% more NOI than those who maintained gross leases.
- Invest in energy efficiency upgrades now. Natural Resources Canada data shows that commercial energy retrofits in Ontario can reduce utility costs by 15-25%, and these improvements are recognized as value-add by AACI-designated appraisers when applying the income approach.
- Challenge your MPAC assessment. If operating costs are rising but your property tax assessment has not been updated, you may be overpaying. A tax assessment appeal appraisal can provide the documentation needed to pursue a reduction.
Owners of multi-unit residential properties face a particular challenge. Ontario's rent increase guideline for 2026 is capped at 2.5%, well below the 8-12% rise in operating costs. This creates a widening gap between revenue growth and expense growth that directly compresses NOI and, by extension, appraised values.
What Should Brokers Tell Their Clients About Rising Operating Costs? 🤝
Brokers should advise clients that lenders across Eastern Ontario are now applying a 5-7% operating expense stress test above trailing actuals, meaning deals structured on historical cost assumptions may not survive underwriting in the current environment. This shift started with institutional lenders in early 2026 and has since spread to credit unions and private lenders operating in the Kingston, Belleville, and Brockville markets.
When advising clients on investment analysis, brokers need to present realistic NOI projections that account for continued cost escalation. CMHC's most recent Rental Market Survey noted that Eastern Ontario's operating expense ratios for multi-unit properties have risen from an average of 38% of gross revenue in 2024 to 43% in 2026. That 5-percentage-point shift represents a material change in underwriting assumptions.
Brokers should also recommend that clients obtain their appraisal before approaching lenders. A CUSPAP-compliant report from an AACI-certified appraiser carries more weight in underwriting than a broker opinion of value, and it eliminates the risk of lender-ordered appraisals coming in below expectations. Aion Appraisals & Consulting Inc. maintains a 100% lender approval rate, which means the report will not create a bottleneck in the deal process.
What's Driving Commercial Operating Costs Higher in 2026? 🔍
Three primary factors are driving Eastern Ontario's commercial operating cost increases as of Q2 2026: Ontario Energy Board-approved utility rate hikes of 6.5% effective January 2026, commercial insurance premium increases averaging 9-14% across the region, and property management labour costs rising 5-7% due to ongoing skilled trades shortages. Each of these cost categories affects different property types with varying intensity.
Utility costs represent the single largest variable expense for most commercial properties. The Ontario Energy Board approved a 6.5% increase to distribution rates in January 2026, and natural gas costs have risen approximately 8% due to increased North American export demand. For properties without modern HVAC systems or building envelope upgrades, these increases translate directly to higher operating costs. Statistics Canada's Industrial Product Price Index confirms that commercial energy costs in Ontario have risen 22% cumulatively since 2022.
Insurance is the second major driver. According to the Insurance Bureau of Canada, commercial property insurance premiums in Ontario rose an average of 11% in 2025 and another 9-14% in the first half of 2026. Eastern Ontario properties located in flood-prone areas near the St. Lawrence River, Rideau Canal, and Bay of Quinte have seen even steeper increases of 15-20%. Owners of insured commercial properties should ensure their coverage reflects current replacement costs rather than market value to avoid both overpaying on premiums and being underinsured.
Labour costs for property management, janitorial services, and maintenance have climbed 5-7% year over year. Ontario's minimum wage increase to $17.20 in October 2025 created upward pressure across the entire wage structure for building operations staff. NAIOP Ontario reported that property management firms in smaller markets like Belleville and Brockville face particular recruitment challenges, often paying 10-15% above GTA rates to retain qualified building operators.
How Does This Trend Play Out Differently Across Eastern Ontario? 🗺️
Operating cost pressures vary significantly across Eastern Ontario's submarkets, with Kingston experiencing the most moderate increases at 7-9% and smaller centres like Belleville and Greater Napanee seeing spikes of 10-14% due to fewer service provider options and older building stock. The region's commercial real estate market functions as an interconnected economic unit stretching from Cobourg in the west through Kingston and east to Brockville, but local conditions create meaningful submarket variation.
| Eastern Ontario Submarket | Operating Cost Increase (YoY %) | Most Affected Property Type | NOI Impact Estimate |
|---|---|---|---|
| Kingston | +7-9% | Class B Office | -4% to -6% NOI compression |
| Belleville / Quinte West | +10-13% | Multi-Unit Residential | -6% to -9% NOI compression |
| Brockville / Leeds-Grenville | +9-12% | Retail Strip Plaza | -5% to -8% NOI compression |
| Cobourg / Port Hope | +8-11% | Mixed-Use | -5% to -7% NOI compression |
| Greater Napanee / Prince Edward County | +11-14% | Seasonal / Tourism Retail | -7% to -10% NOI compression |
Markets like Kingston benefit from a larger, more competitive service provider market and a higher proportion of newer commercial building stock, particularly near the Innovation Park and Cataraqui corridors. These factors moderate cost increases relative to smaller centres. Properties in Belleville and the Quinte West corridor face steeper increases partly because the building stock skews older, with many commercial properties built before 1990 carrying less efficient mechanical systems.
For owners seeking commercial appraisal services in Brockville, understanding how submarket-specific operating cost trends affect valuations is a material factor. An AACI-designated appraiser working in Eastern Ontario will apply local operating cost benchmarks rather than provincial averages, producing a more accurate and defensible valuation.
How Does This Trend Affect Commercial Appraisals in Ontario? ⚖️
Rising operating costs directly change the inputs used in income-based commercial real estate appraisal, requiring AACI-certified appraisers working under CUSPAP standards to carefully project forward-looking expense trajectories rather than relying solely on historical averages. The income approach, which calculates property value by dividing NOI by the applicable cap rate (capitalization rate), is the most common methodology for valuing income-producing commercial properties in Eastern Ontario.
A cap rate (capitalization rate) is the ratio of a property's net operating income to its market value. It serves as the primary metric appraisers use to value income-producing commercial properties in Ontario. When NOI decreases due to rising operating costs, the numerator in this calculation shrinks, and the resulting value falls proportionally. For example, a property with $120,000 in NOI valued at a 6.5% cap rate is worth approximately $1,846,000. If operating costs rise enough to compress NOI to $105,000, that same cap rate produces a value of roughly $1,615,000, a decline of $231,000 or 12.5%.

For specialized situations like multi-unit residential appraisals, appraisers must account for the disconnect between rent-controlled revenue growth and uncapped operating cost increases. This requires careful analysis of lease rollover schedules, tenant turnover rates, and the potential for above-guideline rent increases on unit turnover.
Properties in markets like Cobourg may see additional appraisal complexity where tourism-driven seasonal revenue patterns intersect with year-round fixed operating costs. AACI-designated appraisers apply property-specific expense analysis rather than broad benchmarks in these situations, producing more accurate valuations that lenders can rely on.
Aion Appraisals & Consulting Inc. provides CUSPAP-compliant commercial appraisals across Ontario, completed by AACI-designated appraisers with a verified 5-day turnaround and 100% lender approval rate.

What's the Outlook for Eastern Ontario Operating Costs Over the Next 12 Months? 📈
Most indicators suggest operating costs in Eastern Ontario will continue rising through mid-2027, though the rate of increase should moderate to 5-7% as utility rate adjustments stabilize and insurance markets begin to soften following two years of premium hardening, according to the Insurance Bureau of Canada's June 2026 market outlook. As of July 2026, no major cost category shows signs of declining in absolute terms. The question is the pace of increase, not the direction.
The Bank of Canada's decision to hold its policy rate at 3.25% in June 2026 provides some stability for borrowing costs, but it does not directly address operating expense inflation. Property owners should monitor three key signals over the next 12 months: Ontario Energy Board rate proceedings scheduled for Q4 2026, the commercial insurance renewal cycle in January 2027, and any changes to Ontario's minimum wage scheduled for October 2026.
For owners who have been considering capital improvements to reduce operating costs, the current environment creates a compelling case for action. Energy retrofits that reduce utility costs by 15-20% can partially offset other rising expenses and improve appraised values under the income approach. Properties with documented energy efficiency improvements are also seeing 25-50 basis points of cap rate compression relative to comparable assets with higher operating cost profiles, according to Altus Group's mid-2026 investor sentiment survey.

Frequently Asked Questions ❓
How do rising operating costs affect commercial property values in Eastern Ontario?
Rising operating costs directly reduce net operating income (NOI), which is the primary input for income-based commercial real estate appraisal. In Eastern Ontario, a 10% increase in operating expenses on a property generating $200,000 in gross revenue can reduce NOI by $15,000 to $20,000, potentially lowering appraised value by $200,000 or more depending on the applicable cap rate. AACI-designated appraisers account for both current and projected operating cost trajectories when completing valuations.
Should I get a commercial appraisal now or wait for operating costs to stabilize?
Property owners should not wait. A current commercial real estate appraisal captures today's cost environment and provides a defensible baseline for refinancing, selling, or tax appeal decisions. Waiting risks further NOI compression that could reduce your negotiating position. Aion Appraisals & Consulting Inc. delivers CUSPAP-compliant reports within a 5-day turnaround, giving owners the data they need to act while market conditions are still favourable for strategic moves.
What is net operating income (NOI) and why does it matter for my commercial property?
Net operating income (NOI) is the total revenue a property generates minus all operating expenses, excluding debt service and capital expenditures. NOI is the single most important figure in commercial real estate appraisal because it directly determines property value under the income approach. When operating costs rise and rents remain flat, NOI falls, and so does your property's appraised value. In Eastern Ontario, rising utility and insurance costs are the primary drivers compressing NOI in 2026.
How are lenders reacting to rising operating costs in Eastern Ontario right now?
Lenders are increasing their scrutiny of operating expense projections in Eastern Ontario. Many institutional lenders now require trailing 24-month expense documentation rather than the previous 12-month standard. They are also stress-testing NOI at higher expense ratios before approving refinancing or acquisition financing. Brokers should prepare clients for longer underwriting timelines and ensure all appraisal reports are completed by AACI-certified appraisers with CUSPAP-compliant methodology to avoid lender pushback.
What documentation is needed for a commercial appraisal in Eastern Ontario?
A CUSPAP-compliant commercial real estate appraisal in Eastern Ontario typically requires current rent rolls, trailing 24-month operating statements, and property tax assessment notices. Additional documents may include lease agreements, capital improvement records, and utility cost breakdowns. Aion Appraisals & Consulting Inc. provides a complete documentation checklist at engagement and completes most reports within a 5-day turnaround. All reports are prepared by AACI-designated appraisers and accepted by major Canadian lenders.
How long does a commercial appraisal take in Eastern Ontario?
A commercial appraisal with Aion Appraisals & Consulting Inc. takes 5 business days from engagement to delivery. Complex portfolios or specialized property types may require additional time. All reports are prepared by AACI-designated appraisers, delivered in formats accepted by major Canadian lenders, and compliant with CUSPAP standards. This turnaround applies across Eastern Ontario, including Kingston, Belleville, Brockville, and surrounding communities.
Are property tax assessments in Eastern Ontario keeping pace with rising operating costs?
Property tax assessments in Eastern Ontario have not been updated since the 2016 MPAC reassessment cycle, meaning assessed values do not reflect current operating cost realities. This creates a disconnect where owners may be paying taxes based on outdated valuations while experiencing significantly higher expenses. A professional tax assessment appeal supported by a current AACI-certified appraisal can help owners reduce their tax burden and partially offset rising operating costs.
What should mortgage brokers advise clients about refinancing during a period of rising operating costs?
Brokers should advise clients to lock in refinancing before further NOI compression reduces loan-to-value ratios. Lenders in Eastern Ontario are currently applying more conservative underwriting to properties showing rising expense ratios, which means delays could result in lower approved loan amounts. Brokers should recommend clients obtain a CUSPAP-compliant appraisal from an AACI-designated firm before approaching lenders, ensuring the report reflects current market rents and realistic expense projections.
