Why the Same Duplex Produces Wildly Different Returns Across Ontario

If you have spent any time comparing rental markets across Ontario, you have probably noticed that the same property type can produce dramatically different returns depending on where it sits. A duplex in Belleville and a duplex in Toronto might look similar on paper, but their cap rates tell completely different stories. Understanding those differences is not just useful for academic purposes. It is the difference between buying a property that builds wealth and one that quietly drains it.

At Blue Anchor Property Management, we manage long-term residential rental properties across Central Ontario, covering Oshawa to Belleville, with properties as far north as Campbellford and down into Picton. Cap rate comes up in almost every serious conversation we have about property performance. So we put together this comparison to give Ontario investors a grounded, honest look at how Belleville, Toronto, and Ottawa stack up right now.

A quick note before we dive in: cap rate figures vary by property type, condition, neighbourhood, and how you calculate expenses. Where we cite specific figures, we name the source or label the example as illustrative. Use this as a starting point for your own analysis, not as financial advice. Always consult a qualified financial advisor or real estate accountant before making investment decisions.

What Is a Cap Rate?

A capitalization rate, or cap rate, measures how much annual income a property generates relative to its current market value. The formula is straightforward:

Cap Rate = Net Operating Income (NOI) / Current Property Value

Net Operating Income is your gross annual rental income minus all operating expenses. Operating expenses include property taxes, insurance, maintenance, property management fees, and any utilities you cover as a landlord. What it does not include is your mortgage payment. Cap rate is a pre-financing metric, which is part of why it is so useful for comparing properties across different purchase scenarios.

To make this concrete, here is an illustrative example. Suppose a property in Belleville generates $24,000 per year in gross rent and operating expenses total $10,000. The NOI is $14,000. If the purchase price was $280,000, the cap rate is 5.0%. That same NOI on a $700,000 Toronto property produces a cap rate of just 2.0%. The income is identical; the entry price is what changes the math entirely.

Cap rate also helps you evaluate whether a property is performing at market rate or underperforming relative to similar properties nearby. We use it as one of several benchmarks when we talk to landlords about whether their current rents and expense structure are working in their favour. For a broader look at the metrics that matter, see our post on KPIs every investment property owner must know.

How to Calculate Cap Rate Accurately in Ontario

Many investors underestimate their operating expenses, which inflates their cap rate and makes a property look more attractive than it actually is. Here is what a realistic Ontario expense breakdown looks like for a single-family rental or small multi-unit property:

• Property taxes: Belleville and Quinte West carry higher mill rates than Toronto on a percentage basis, though absolute dollar amounts are lower because assessed values are lower.
• Insurance: Landlord insurance for a typical Belleville rental has generally run in the range of $1,200 to $2,000 per year, though premiums have been rising across Ontario. Toronto properties often run higher due to replacement cost values. Get a current quote rather than relying on older estimates.
• Maintenance and repairs: A conservative rule of thumb is 1% of property value per year. Older properties in Central Ontario can run higher. We have written separately about the hidden costs of owning rental properties that many investors miss.
• Property management fees: Fees vary by provider and service level. At Blue Anchor, our Standard plan is 5% of collected rent per unit per month with a $50 minimum on occupied units and no fee in any month a unit sits vacant with no rent collected. Our Platinum plan is $295 per unit per month on a 12-month minimum with ancillaries included. Tenant placement on Standard is 50% of one month's rent. You can review the full breakdown on our pricing page.
• Vacancy allowance: Even in tight markets, budget 4% to 8% of gross rent for vacancy and turnover costs.
• Utilities (if landlord-paid): Water, heat, and hydro can add several thousand dollars per year for a single-family home in Ontario, depending on the season and property size.

Once you have an accurate NOI, divide it by the purchase price or current market value. It is worth recalculating cap rate using current market value periodically, not just your original purchase price. A property bought in Belleville several years ago has likely appreciated, which means your effective cap rate on current value may be lower than it was at purchase, even if rents have increased.

Cap Rate Comparison: Belleville vs Toronto vs Ottawa

Rather than cite figures we cannot currently attribute to a named source, we will describe each market qualitatively and show the method with illustrative numbers. Markets shift, and any specific figure we print today could be outdated within months. The directional relationships between these three cities, however, have been consistent for years and remain useful for framing your analysis.

Toronto

Toronto remains one of the most expensive residential real estate markets in Canada. Even after the price corrections seen in 2022 and 2023, investment-grade properties in Toronto proper, meaning detached homes and small multi-unit buildings in the two-to-four unit range, carry purchase prices that make cash flow extremely difficult to achieve.

Rents in Toronto are high in absolute terms, but they have not kept pace with property values over the long run. As a result, residential cap rates in Toronto have historically sat in the low single digits, often in the 2% to 3.5% range depending on property type and neighbourhood. The math is challenging for cash-flow investors. To illustrate: a property purchased at $1.2 million generating $3,500 per month in rent produces gross annual income of $42,000. After realistic operating expenses, the NOI might land around $20,000 to $24,000, producing a cap rate somewhere between 1.7% and 2.0%. These are illustrative figures, not current market quotes.

Investors buy Toronto for appreciation and long-term equity growth, not for monthly cash flow. That is a legitimate strategy, but it is a different strategy, and it carries different risks, particularly in periods when price growth slows or stalls.

Ottawa

Ottawa occupies a middle position. As the national capital, it benefits from a large, stable base of federal government employees and a relatively low unemployment rate compared to other major Ontario cities. That stability supports consistent rental demand and lower vacancy risk.

Cap rates in Ottawa for residential rentals have generally been higher than Toronto but lower than smaller Central Ontario markets. The federal workforce creates a reliable tenant pool, but property values in Ottawa have also risen substantially over the past decade, compressing returns. Investors in Ottawa tend to find a balance between appreciation potential and modest cash flow, though achieving strong cash flow still requires careful property selection and disciplined expense management.

Ottawa also has a more active purpose-built rental sector than many Ontario cities, which means individual investors face meaningful competition when setting rents and attracting tenants.

Belleville and Central Ontario

This is where the cap rate story becomes most interesting for the investors we work with at Blue Anchor. Belleville, Trenton, Cobourg, Oshawa, Quinte West, and Picton all offer entry prices that are substantially lower than Toronto or Ottawa, while rents, though lower in absolute terms, have not compressed to the same degree relative to purchase price.

To illustrate the difference: a small multi-unit property in Belleville purchased for $400,000 generating $3,000 per month in total gross rent produces $36,000 in annual gross income. After realistic operating expenses of perhaps $14,000 to $16,000, the NOI lands around $20,000 to $22,000. That produces a cap rate in the range of 5% to 5.5%. These are illustrative numbers only, but they reflect the directional reality we see in our market regularly.

That gap between a 2% Toronto cap rate and a 5% Belleville cap rate is not trivial. It represents real monthly cash flow that either exists or does not. For investors who need their portfolio to generate income now rather than waiting for appreciation to materialize, Central Ontario has a compelling case to make.

What Drives Cap Rate Differences Across Ontario?

Cap rate differences between cities come down to a few consistent factors:

• Speculative demand: In markets like Toronto, a significant portion of purchase prices reflects anticipated future appreciation rather than current income. That drives prices up faster than rents, compressing cap rates.
• Supply and demand for rentals: Markets with tight rental supply and high tenant demand support stronger rents relative to purchase prices, which improves cap rates for investors.
• Economic base: Cities with diversified or stable employment bases tend to have lower vacancy risk, which supports more reliable NOI calculations.
• Property tax structures: Municipal tax rates vary considerably across Ontario. Higher mill rates in smaller municipalities can reduce NOI, partially offsetting the advantage of lower purchase prices.
• Operating cost differences: Insurance, maintenance costs, and utility expenses vary by region and property age. Older housing stock in some Central Ontario communities can carry higher maintenance costs than newer builds in suburban markets.

Should You Chase the Highest Cap Rate?

Not automatically. A high cap rate can reflect genuine value, or it can reflect risk that the market has already priced in. A property with a 7% cap rate in a market with declining population, weak employment, and rising vacancy is not necessarily a better investment than a 5% cap rate property in a stable, growing community.

The questions worth asking alongside cap rate include: What is the vacancy trend in this market? Is the tenant pool stable? What is the condition of the building and what deferred maintenance exists? What does the regulatory environment look like for landlords?

On that last point, Ontario's landlord-tenant framework has continued to evolve. Bill 60, which received Royal Assent on November 27, 2025, shortened the N4 notice period from 14 days to 7 days effective September 21, 2026, and introduced a written persistent late payment test for N8 applications. Bill 97, passed in 2023, brought renovation right-of-first-refusal duties and a bad faith presumption on own-use eviction notices. These changes affect how you manage non-payment situations and what documentation you need to maintain. Understanding the regulatory context is part of evaluating any Ontario market. Our post on Ontario eviction rule changes in 2026 covers this in more detail.

The 2026 rent increase guideline is 2.1%, which applies to most existing tenancies. That figure matters for your forward-looking NOI projections on occupied units.

Cap rate is a snapshot. A good investment requires understanding what that snapshot is likely to look like in three, five, and ten years. We encourage investors to read our post on what to look for when buying a rental property before making any acquisition decision.

Why Central Ontario Investors Are Rethinking Their Strategy

We have seen a meaningful shift in the conversations we have with investors over the past few years. Landlords who previously focused exclusively on the Greater Toronto Area have been looking east and north, drawn by the combination of lower entry prices, stronger cap rates, and a tenant base that has grown as remote work made smaller cities more viable for working households.

Markets like Belleville, Trenton, Cobourg, and Oshawa have all attracted attention from investors who want income now rather than deferred appreciation. That increased interest has pushed prices up in some of these markets, which is worth accounting for in your analysis. The gap between Central Ontario and Toronto cap rates has narrowed somewhat from where it was five years ago, but it remains substantial.

Blue Anchor manages properties across this corridor and sees the performance data from these markets directly. If you are evaluating a specific property or community, we are happy to share what we observe on the ground. Our Belleville property management page and our Oshawa property management page are good starting points if you want to understand how we work in each market.

Frequently Asked Questions

What is a good cap rate for a rental property in Ontario?

There is no universal answer, because a good cap rate depends on your investment goals, the specific market, and the risk profile of the property. In Central Ontario markets like Belleville and Trenton, cap rates in the 4.5% to 6% range are generally considered reasonable for residential rentals, though this varies by property type and condition. In Toronto, investors routinely accept cap rates below 3% because they are prioritizing appreciation. Neither approach is wrong; they reflect different strategies with different risk and return profiles.

Does cap rate include mortgage payments?

No. Cap rate is calculated using Net Operating Income, which excludes financing costs. This is intentional. It allows you to compare properties regardless of how they are financed. Your actual cash flow after mortgage payments will be lower than what cap rate alone suggests, sometimes significantly lower depending on your down payment and interest rate. Always model your cash-on-cash return separately to understand what a property will actually put in your pocket each month.

How does the 2026 rent increase guideline affect cap rate calculations?

The 2026 rent increase guideline is 2.1%, set by the Ontario government. This applies to most existing tenancies covered under the Residential Tenancies Act. For cap rate purposes, it means that your NOI on occupied units can grow by up to 2.1% through guideline increases this year, assuming you serve the appropriate N1 notice and your leases qualify. Units that turn over are not subject to rent control under current Ontario rules, which means vacancy can actually reset rents to market rates. This distinction matters significantly for properties with below-market rents on long-term tenancies.

What expenses do investors most commonly forget when calculating cap rate?

The most common omissions we see are vacancy allowance, capital reserve for major repairs, and property management fees. Many self-managing landlords calculate cap rate without accounting for management costs, which makes their numbers look better than they would be under professional management. They also tend to underestimate maintenance, particularly on older properties. We have written about the hidden costs of owning rental properties in more detail if you want to build a more complete expense model.

Is cap rate the only metric I should use to evaluate a rental property?

No. Cap rate is a useful starting point, but it does not tell you everything. Cash-on-cash return accounts for your financing costs and tells you what you are actually earning on the cash you invested. Gross rent multiplier gives you a quick sense of how a property is priced relative to its income. Internal rate of return models the full investment over time, including appreciation and eventual sale proceeds. We use cap rate as one benchmark among several when we talk to investors about property performance. A property that looks strong on cap rate but has deferred maintenance, a difficult tenant situation, or a weak local rental market may still be a poor investment.
