Rising Operating Costs and NOI Pressure: What Eastern Ontario Commercial Property Owners Need to Know 📊
A multi-unit property owner in Eastern Ontario, Canada recently discovered that insurance premiums alone had jumped 25% in a single renewal cycle, pushing total operating expenses past the growth in rental income for the first time in a decade. That owner is far from alone. Across the Ottawa-Gatineau corridor and the broader Eastern Ontario region, escalating operating costs are compressing net operating income and fundamentally altering how commercial properties are valued.
What Is the Operating Cost Trend in Eastern Ontario Right Now? 📍
Operating expenses for commercial properties across Eastern Ontario have increased by roughly 18% since 2023, driven primarily by insurance, property taxes, utilities, and labour costs, according to BOMA Canada's 2025 operating cost benchmarks. Net operating income (NOI) is the total revenue a commercial property generates minus all operating expenses, excluding mortgage payments and capital expenditures. NOI is the single most important figure in the income approach to commercial real estate appraisal because it determines property value when divided by the cap rate.
"In Eastern Ontario, commercial property operating costs have risen approximately 18% since 2023, while average gross rents have grown only 8 to 10% over the same period, creating a widening NOI gap that directly affects appraised values."
This gap matters because every dollar of lost NOI translates into a proportionally larger reduction in market value. For a property with a 6.5% cap rate (capitalization rate), which is the ratio of a property's net operating income to its market value, each $10,000 decline in annual NOI reduces appraised value by roughly $154,000. In a region where commercial property appraisal activity is closely tied to refinancing cycles and institutional lending, that math has real consequences for owners and the brokers who serve them.
What Should Property Owners in Eastern Ontario Do Now? 🏢
Property owners should conduct a thorough review of their current operating statements and obtain a current commercial real estate appraisal before entering any refinancing or sale process in 2026. In our experience working with property owners across Eastern Ontario, many are surprised by the cumulative effect of cost increases that crept in over two or three renewal cycles. Insurance, in particular, has moved sharply enough that a policy renewed in early 2024 may look entirely different at the 2026 renewal.
Owners considering mortgage refinancing appraisals should factor in several considerations:
- If your NOI has declined by more than 5% since your last appraisal, your property's current market value has likely shifted materially. A property worth $2.4 million at a 6.5% cap rate with $156,000 in NOI drops to $2.25 million if NOI falls to $146,000.
- Lenders will underwrite based on actual, trailing NOI from the most recent 12 months. Owners who proactively reduce controllable costs before seeking a valuation can improve their position.
- For those weighing a sale, the current environment favours disposing of assets with high controllable cost exposure, such as older office buildings with inefficient mechanical systems, before further compression occurs.
Owners of multi-unit residential properties face a specific challenge. Ontario's rent increase guideline for 2026 is capped at 2.5% for units covered under the Residential Tenancies Act, while operating costs for those same buildings are climbing at two to three times that rate. This structural mismatch creates the sharpest NOI compression in the multi-unit sector.
What Expense Reductions Have the Biggest Impact on Property Value?
Reducing insurance premiums and utility costs delivers the greatest per-dollar impact on appraised value because these two categories represent the largest and fastest-growing expense line items for Eastern Ontario commercial properties. Energy efficiency retrofits such as LED lighting conversions, building envelope improvements, and HVAC upgrades can reduce utility costs by 10 to 20%, according to Natural Resources Canada. Re-tendering insurance policies through a commercial broker rather than simply accepting renewal terms has saved some Eastern Ontario owners 8 to 15% on annual premiums. A property tax assessment appeal through MPAC is another avenue that can yield ongoing annual savings when an assessment exceeds market value.
What Should Brokers Tell Their Clients About Rising Operating Costs? 🤝
Mortgage brokers should advise clients that declining NOI will directly affect loan-to-value ratios and that obtaining a current CUSPAP-compliant appraisal before approaching lenders is now a critical step in every refinancing conversation. Lenders across Canada, including the major banks and CMHC, underwrite commercial mortgages using a debt coverage ratio (DCR) that relies on verified NOI. When NOI shrinks, the maximum supportable loan amount shrinks with it.
Here is what that looks like in practice. A client whose property had a $160,000 NOI two years ago may now show $138,000 after cost increases. At a 1.25x DCR requirement and a 5.2% mortgage rate, the maximum loan drops from approximately $2.05 million to $1.77 million. That $280,000 gap catches clients off guard if they have not reviewed their numbers recently.
When advising clients on investment analysis, brokers should encourage a full operating cost review at least 90 days before any mortgage renewal or refinancing application. This gives clients time to address controllable costs, gather documentation, and commission an appraisal. Lenders expect to see trailing 12-month actuals, and a well-prepared file with a current AACI-certified appraisal report reduces turnaround time and improves approval odds.
What's Driving Operating Cost Increases Across Eastern Ontario? 🔍
Four primary factors are driving operating cost inflation for commercial properties in Eastern Ontario as of Q1 2026: insurance premium escalation, municipal property tax increases, utility rate adjustments, and tight labour markets for building maintenance and property management. Each of these factors has structural characteristics that suggest they will persist through at least late 2026.
Insurance premiums have been the most dramatic mover. Following significant weather-related claim events across Ontario in 2023 and 2024, commercial property insurers have repriced risk across the board. BOMA Canada reported that average commercial property insurance costs in Ontario rose 20 to 30% between 2023 and 2025, with some older buildings and properties in flood-prone areas seeing even steeper increases. Eastern Ontario's exposure to Ottawa River flood plain risk has compounded this trend in certain corridors.
Municipal property taxes continue to rise as municipalities face their own inflationary pressures. Ottawa's 2026 budget included a 4.9% residential tax increase that flows through to commercial rates. Smaller municipalities in the region, including Kingston, Belleville, and surrounding townships, have enacted comparable increases ranging from 3.5 to 6.2%. For commercial property owners, property tax often represents the single largest operating expense line item, sometimes exceeding 30% of total costs.
Utility costs have climbed steadily as Ontario's Global Adjustment charges and natural gas distribution rates increased through 2025. Statistics Canada data shows the Ontario commercial and industrial electricity price index rose 12% between January 2024 and January 2026. Maintenance labour costs reflect the broader skilled trades shortage, with HVAC technicians, electricians, and plumbers commanding 10 to 15% higher rates than they were two years ago, according to NAIOP Ontario chapter surveys.
How Does This Trend Play Out Differently Across Eastern Ontario? 🗺️
The NOI compression effect varies significantly by property type and sub-region within Eastern Ontario, with multi-unit residential and older office properties in Ottawa showing the tightest squeeze while industrial properties in the Kingston corridor have remained more resilient. Understanding these differences is essential for owners, brokers, and lenders evaluating individual assets.
| Property Type / Sub-Region | Avg. Operating Cost Increase (2023-2026) | Avg. Rent Growth (2023-2026) | NOI Impact |
|---|---|---|---|
| Multi-Unit Residential (Ottawa) | +19% | +7% | Significant compression |
| Office (Ottawa CBD) | +17% | +3% | Severe compression |
| Retail (Eastern Ontario corridor) | +15% | +9% | Moderate compression |
| Industrial (Kingston corridor) | +14% | +16% | Stable to expanding |
| Mixed-Use (Belleville / Quinte West) | +16% | +10% | Moderate compression |
Markets like Kingston and Belleville illustrate different aspects of this trend. Kingston's industrial sector has benefited from strong logistics demand tied to the Highway 401 corridor and proximity to the U.S. border, allowing landlords to push rents faster than costs have risen. Ottawa's office market, by contrast, still carries the effects of the federal government's hybrid work policies, which have kept vacancy rates above 12% and limited landlords' ability to pass through rising costs.
For owners seeking a mixed-use property appraisal in Belleville, understanding how each component of a mixed-use building responds differently to cost pressure is a material factor in determining overall value. The residential floors may face rent-controlled income growth while the commercial floors have more flexibility.
How Does This Trend Affect Commercial Appraisals in Ontario? ⚖️
Rising operating costs directly affect how AACI-designated appraisers calculate value under the income approach, which is the primary valuation method for income-producing commercial properties under CUSPAP standards. When operating costs rise and NOI falls, the income approach produces a lower value, all else being equal. But the analysis goes deeper than simply plugging in current numbers.
An AACI-certified appraiser evaluates whether current operating costs are typical, or whether they include anomalies that should be normalized. For example, a property whose insurance costs spiked 40% due to a recent claim may be normalized to market-typical rates if the claim circumstances are non-recurring. Similarly, a building undergoing a major maintenance catch-up may show temporarily elevated repair costs that an appraiser would adjust.
The direct comparison approach also reflects operating cost trends indirectly. When comparable sales show declining prices per square foot, rising costs are often the underlying driver. Appraisers working under CUSPAP standards must explain the basis for all adjustments, giving lenders and owners transparency into how costs affected the final value estimate.
"Aion Appraisals & Consulting Inc. provides CUSPAP-compliant commercial real estate appraisal reports prepared by AACI-designated appraisers with a verified 5-day turnaround and 100% lender approval rate across all major Canadian financial institutions."
For specialized situations like office building appraisals, appraisers must account for both the direct cost impact and the indirect effect on tenant retention and vacancy assumptions. A building with above-market operating costs is more likely to experience tenant turnover, which compounds the NOI problem through lost rent and leasing costs.
Properties in markets like Oshawa may see different cost dynamics than those in Ottawa's core, and an appraiser with regional expertise can distinguish between localized conditions and province-wide trends. This distinction matters for both accuracy and lender confidence in the report.
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. All reports meet the standards required by major Canadian lenders, CMHC, and institutional investors.
What's the Outlook for Eastern Ontario Over the Next 12 Months? 📈
Most indicators suggest that operating cost pressure in Eastern Ontario will persist through at least Q4 2026, though the rate of increase should moderate from the 2024-2025 highs as insurance markets stabilize and the Bank of Canada's rate cuts filter through to borrowing costs. As of March 2026, the Bank of Canada's overnight rate sits at 2.75%, down from its peak of 5.0% in mid-2023, which has eased debt service costs even as operating expenses remain elevated.
The key variables to watch over the next 12 months include insurance renewal cycles in Q2 and Q3 2026, Ontario's electricity rate adjustments scheduled for May 2026, and the outcome of MPAC's ongoing valuation updates that will affect 2027 property tax bills. Each of these could either accelerate or moderate the NOI compression trend.
For industrial assets along the Highway 401 corridor between Kingston and Cornwall, NOI growth may actually continue as logistics demand from cross-border trade remains robust. The sector-level divergence highlighted in the regional data above is likely to persist, making asset-specific analysis more important than ever.

Frequently Asked Questions ❓
How do rising operating costs affect the value of my commercial property in Eastern Ontario?
Rising operating costs directly reduce net operating income (NOI), which is the primary input in the income approach to commercial real estate appraisal. In Eastern Ontario, a 10% increase in operating costs on a property with a 6.5% cap rate can reduce appraised value by roughly $150,000 per $10,000 of lost NOI. AACI-designated appraisers account for current and projected expense levels when preparing CUSPAP-compliant valuations for commercial property appraisals.
What is net operating income and why does it matter for commercial real estate?
Net operating income (NOI) is the total revenue a commercial property generates minus all operating expenses, excluding mortgage payments and capital expenditures. NOI is the single most important figure in commercial real estate appraisal because it drives property value under the income approach. When operating costs rise faster than rental income, NOI compresses and property values decline proportionally based on the applicable cap rate.
Which operating costs are increasing the fastest for Ontario commercial properties in 2026?
Property insurance premiums have seen the steepest increases, rising approximately 20 to 30% across Eastern Ontario since 2023, according to industry data from BOMA. Municipal property taxes, utility costs, and maintenance labour follow closely, each climbing between 8 and 15% over the same period. These four expense categories together account for over 70% of typical operating budgets for multi-unit and office properties in the region.
Should I get a commercial appraisal now or wait for operating costs to stabilize?
Getting a commercial real estate appraisal now is generally advisable if you are refinancing, selling, or managing estate or tax obligations. Waiting for costs to stabilize introduces uncertainty, and lenders require current valuations regardless of market timing. An AACI-certified appraiser can reflect both current expense levels and supportable forward projections, giving you a defensible value. Aion Appraisals & Consulting Inc. delivers CUSPAP-compliant reports within a 5-day turnaround.
How should mortgage brokers advise clients whose properties have declining NOI?
Brokers should proactively communicate that declining NOI will affect loan-to-value ratios and potentially trigger covenant reviews on existing facilities. Recommending a current commercial real estate appraisal before approaching lenders gives clients a clear picture of where value stands. Lenders across Canada accept CUSPAP-compliant reports from AACI-designated appraisers, and having one in hand before a renewal discussion strengthens the client's negotiating position.
How long does a commercial appraisal take in Eastern Ontario?
A commercial real estate appraisal with Aion Appraisals & Consulting Inc. takes 5 business days from engagement to delivery. Complex portfolios or specialized property types such as mixed-use buildings or large industrial facilities 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.
Can property owners reduce operating costs to protect their property value?
Yes, targeted expense management can protect NOI and by extension property value. Common strategies in Eastern Ontario include energy efficiency retrofits that reduce utility costs by 10 to 20%, competitive re-tendering of insurance policies, appealing MPAC property tax assessments, and renegotiating service contracts. An AACI-certified appraiser can identify which cost reductions would have the greatest impact on appraised value under the income approach.
What documentation is needed for a commercial appraisal in Ontario?
A CUSPAP-compliant commercial appraisal in Ontario typically requires current rent rolls, two to three years of operating statements, and a copy of the property tax assessment notice. Lease agreements, capital expenditure records, and recent building condition reports are also helpful. Insurance appraisal assignments may require additional documentation such as replacement cost estimates and policy details. AACI-designated appraisers work with whatever information is available to produce a defensible valuation.
