Rental Income Properties in Ontario: What you Need to Know

Written by the Keith and Françoise Real Estate Team, Ontario REALTORS®, with eXp Realty Brokerage. We help investors across the GTA and Niagara Region evaluate rental income properties in Ontario, run the numbers, and build portfolios that generate real cash flow.

Buying a rental property is the most common entry point for real estate investors in Ontario. The concept is straightforward: you purchase a property, rent it to a tenant, and collect monthly income that covers your costs with cash flow left over. But the gap between concept and reality is where most new investors run into trouble.

Ontario’s rental market has shifted. Vacancy rates are trending toward 3% or higher in many cities. New rental supply is coming online. And the 2026 OSFI mortgage rules mean each property must stand on its own financially. This article covers how to evaluate rental income properties in Ontario, calculate real cash flow, and avoid the mistakes that turn a potential asset into a monthly liability.

For an overview of all investment strategies, see our guide to real estate investing in Ontario.

How to Calculate Cash Flow on a Rental Property

Cash flow is the single most important number in rental property investing. It tells you whether a property makes money or loses money every month. Here is how to calculate it.

Monthly Income

Start with the realistic monthly rent. Check comparable listings in the area on sites like Rentals.ca or Kijiji. Don’t use the asking rent from the listing agent or the seller’s optimistic estimate. Use actual rented comparables in the same neighbourhood, with the same number of bedrooms and similar finishes.

Monthly Expenses

Subtract all of the following from your rental income:

Mortgage payment (principal and interest). Property taxes (divide annual amount by 12). Property insurance. Maintenance and repairs (budget 1% to 2% of the property’s value per year, divided by 12). Vacancy allowance (5% to 8% of annual rent, divided by 12). Property management fees (8% to 12% of rent, if applicable). Utilities you pay as the landlord (water, heat, hydro, depending on your lease terms).

The Cash Flow Formula

Monthly rent minus total monthly expenses equals cash flow. If the result is positive, the property generates income. If it is negative, you are paying out of pocket every month to own it. A property with negative cash flow is not an investment. It is a bet on future appreciation, and that is speculation.

Example: A Brampton townhouse rents for $2,800 per month. Your mortgage payment is $1,650, property taxes are $350, insurance is $120, maintenance reserve is $200, vacancy reserve is $170, and management is $280. Total expenses: $2,770. Cash flow: $30 per month. That is a breakeven property, not a strong investment. One unexpected repair wipes out your annual cash flow.

Which Property Types Work Best as Rentals in Ontario

Not every property type works as a rental. The best choice depends on your market, budget, and the tenant pool you want to attract.

Single-Family Homes

Detached and semi-detached houses attract long-term tenants, usually families. Turnover is lower and tenants tend to maintain the property better. The downside is higher purchase prices, which often mean tighter cash flow. In Mississauga or Oakville, a single-family home may not cash flow at all. In Hamilton or St. Catharines, the numbers are more likely to work.

Condos

Condos have lower purchase prices and attract young professionals and students. Maintenance is handled by the condo corporation, which simplifies ownership. The downside is monthly condo fees, which eat into cash flow and can increase annually. Special assessments for building repairs are an additional risk. Before buying a condo as an investment, review the reserve fund study and the corporation’s financial statements.

Townhouses

Townhouses split the difference between houses and condos. They attract families and couples who want more space than a condo but cannot afford a detached home. Monthly fees (if freehold) are minimal. Rental demand for townhouses is strong across Brampton, Milton, and Burlington.

Multi-Unit Properties

Duplexes, triplexes, and small apartment buildings generate the strongest cash flow because multiple tenants share a single mortgage. For a detailed look at this approach, see our guide to duplexes and multi-family investing in Ontario.

Operating Expenses Every Investor Must Budget For

New investors consistently underestimate expenses. Here is what a realistic operating budget looks like.

Maintenance and Repairs

Budget 1% to 2% of the property’s value per year. On a $600,000 property, that is $6,000 to $12,000 annually. This covers routine maintenance (furnace servicing, plumbing repairs, appliance replacements) and builds a reserve for larger expenses like a roof or water heater.

Vacancy

No property stays rented 100% of the time. Budget 5% to 8% of annual rent for vacancy periods. With Ontario vacancy rates trending upward, the higher end of that range is more realistic in 2026. On a $2,800 per month rental, 8% vacancy means $2,688 per year in lost income.

Property Management

If you hire a property manager, expect to pay 8% to 12% of monthly rent. This covers tenant placement, rent collection, maintenance calls, and lease administration. Even if you plan to self-manage, factor this cost into your analysis. Your time has value, and your situation may change.

Insurance

Landlord insurance costs more than homeowner insurance, typically $1,200 to $2,400 per year depending on the property. Make sure your policy covers rental income loss, liability, and property damage.

Property Taxes

Property taxes vary by municipality. Brampton and Mississauga have some of the highest rates in the GTA, while Toronto’s rate is lower but property values are higher. Always verify the current tax amount with the municipality before buying.

Financing a Rental Property Under the 2026 OSFI Rules

The 2026 OSFI mortgage rules fundamentally changed how rental properties are financed in Ontario. Each investment property must now stand on its own financially. The property’s rental income must support its own mortgage, taxes, and operating costs.

Lenders classify rental property mortgages as IPRRE (income-producing residential real estate) when more than 50% of the qualifying income comes from rent. This classification means higher interest rates and stricter terms. Income recycling, where investors used the same personal salary to qualify for multiple mortgages, is no longer permitted.

For non-owner-occupied rentals, you need a minimum 20% down payment. Lenders count only 50% to 70% of expected rental income when calculating qualification. If the property’s income doesn’t cover its costs on paper, the mortgage won’t be approved regardless of your personal salary.

This makes cash flow analysis more important than ever. Before making an offer, confirm that the property’s rental income supports the mortgage at the rate your lender quotes, with all expenses included. Properties that worked on paper under the old rules may not qualify under the new ones.

Rising Vacancy and What It Means for Rental Investors

Ontario’s rental market is shifting. Vacancy rates are trending toward 3% or higher in many cities as new purpose-built rental supply comes online and demand slows. A significant reduction in international students arriving in Ontario has eased pressure on the rental market, particularly in university cities like Hamilton, St. Catharines, and areas near Toronto’s colleges.

For investors, this means three things. First, finding tenants takes longer than it did two or three years ago. Budget more time and money for vacancy between tenants. Second, tenants have more options, so the condition and pricing of your unit matters more. A dated unit at top-of-market rent will sit empty while a well-maintained unit at a fair price fills quickly. Third, rent growth has slowed. Don’t project annual rent increases into your cash flow model. Assume flat rents for the first two to three years and treat any increase as a bonus.

This is not a reason to avoid investing. It is a reason to be more disciplined about the properties you buy and the assumptions you make.

Where Rental Income Properties Make Sense in Ontario

Location determines your tenant pool, rental rate, vacancy risk, and long-term appreciation. Here is where the rental math works for investors in 2026.

Brampton offers strong rental demand from families and new residents. Entry prices are lower than Mississauga and Toronto, which improves cash flow ratios. Hamilton continues to attract investors for the same reason: lower prices relative to rental rates. St. Catharines and the broader Niagara Region provide some of the most affordable entry points in southern Ontario, with growing demand from GTA buyers relocating.

In all of these markets, due diligence matters more than the city name. A property in a high-demand neighbourhood of Hamilton can outperform a property in a slow pocket of Brampton. Analyze the specific location, comparable rents, and vacancy trends before committing.

For tenanting your property, proper screening is essential. See our guide to tenant screening in Ontario. And for setting up your lease correctly, read our guide to Ontario lease clauses.

Before helping any of our clients purchase a rental property, we run the numbers first. There was a time when a small monthly shortfall wasn’t a deal breaker because home prices were rising quickly and you were building equity. That is not the case in today’s market. With rents softening and interest rates still elevated, it makes sense to go in with a sizeable down payment and conservative cash flow expectations.

Common Mistakes With Rental Income Properties

Most rental property failures in Ontario come from the same mistakes. Avoiding them puts you ahead of the majority of first-time investors.

Using the Seller’s Rent Estimate

Sellers and listing agents often inflate expected rents to make properties look more attractive. Always verify rents with current comparable listings and recently rented units in the same area. If you can’t confirm the rent, assume a lower number.

Ignoring Vacancy in Cash Flow Projections

A property that cash flows at 100% occupancy but loses money with one month vacant is not a strong investment. Build vacancy into every calculation. In the current market, 8% is a safer assumption than 5%.

Buying Based on Appreciation Alone

Counting on property values to rise is not a strategy. If the property doesn’t cash flow at today’s rents and today’s interest rate, it doesn’t work. Appreciation is a long-term bonus for properties that already generate income.

Underestimating the Work of Being a Landlord

Tenants call at inconvenient times. Repairs cost more than expected. The Landlord and Tenant Board process for non-paying tenants takes months. If you are not prepared for this, hire a property manager or reconsider whether rental property investing is right for you.

Rental income, vacancy rates, property values, and financing terms vary by location, property type, and market conditions. This article reflects Ontario market conditions as of early 2026.
