Keep More of What You Earn: Tax Deductions for Ontario Landlords
Owning rental property in Ontario can be a great investment, but it comes with real costs. Mortgage interest, repairs, insurance, property taxes — it adds up fast. The good news is that the Canada Revenue Agency (CRA) allows rental property owners to deduct most of these expenses from their rental income, which can significantly reduce what you owe at tax time.
This guide breaks down the deductions that matter most for Ontario landlords, explains how to claim them properly, and helps you avoid some of the common mistakes that cost property owners money every year. That said, tax situations vary, so always work with a qualified accountant familiar with real estate income before filing.
How Rental Income and Expenses Work for Tax Purposes
When you own a rental property in Canada, the income you earn is considered business income for tax purposes and must be reported on your T1 personal tax return using Form T776 (Statement of Real Estate Rentals). You report your gross rental income and then subtract eligible expenses to arrive at your net rental income, which is what gets taxed.
The basic principle is straightforward: if an expense is incurred to earn rental income, it is generally deductible. The CRA does draw a clear line, though, between current expenses and capital expenses. Current expenses are day-to-day costs that keep your property running. Capital expenses improve the property or extend its useful life. This distinction matters a lot, because capital expenses are handled differently through the Capital Cost Allowance (CCA) system rather than as a straight deduction.
The Deductions Ontario Landlords Should Know About
Mortgage Interest
This is often the largest deduction a landlord can claim. You can deduct the interest portion of your mortgage payments on your rental property. Note that it is the interest only, not the principal repayment. Keep your annual mortgage statement handy, as your lender will typically provide a breakdown of how much you paid in interest for the year.
Property Taxes
Whatever you paid in municipal property taxes for your rental property during the year is fully deductible. In Ontario, property tax rates vary by municipality, so this amount will differ depending on whether your property is in Barrie, Orillia, Midland, or another community in Central Ontario.
Insurance Premiums
Landlord insurance premiums paid on your rental property are deductible. This includes building insurance and liability coverage. Keep in mind that tenant insurance is the tenant's responsibility, but your own policy costs come off your rental income.
Repairs and Maintenance
This is where things get a little nuanced. Routine repairs and maintenance costs are fully deductible in the year you pay them. Fixing a leaking roof, replacing a broken furnace part, repainting a unit between tenants — these are current expenses. However, replacing the entire roof or adding a new bathroom is considered a capital improvement and must be treated differently. When in doubt, ask your accountant how to classify a specific project.
Property Management Fees
If you work with a property management company, the fees you pay are a deductible expense. This includes monthly management fees, leasing fees, and any other service charges. For many landlords, this deduction alone makes professional management an even smarter financial decision.
Advertising Costs
Money spent advertising your rental unit is deductible. This covers paid listings on rental platforms, signage, and any other marketing costs you incur to find tenants.
Utilities
If you pay for any utilities on behalf of your tenants (water, heat, electricity, internet in some cases), those costs are deductible. If your tenant pays their own utilities, you cannot claim them.
Professional and Legal Fees
Accounting fees for preparing your rental income statement, legal fees for drafting a lease or dealing with a tenant dispute under the Residential Tenancies Act, and costs related to collecting overdue rent can all be deductible. Legal fees to purchase a property are not deductible, though they may be added to the adjusted cost base of the property.
Office Expenses and Record-Keeping
If you maintain records, purchase software to manage your properties, or incur other administrative costs related to your rental business, a reasonable portion of those expenses may be deductible. Keep receipts and be prepared to justify these if asked.
Capital Cost Allowance: The Depreciation Deduction
The CCA allows you to deduct a portion of the cost of depreciable property over time. Rental buildings fall into CCA Class 1 (4% per year) or Class 3, depending on when they were built. While this can create a useful deduction, there is an important catch: claiming CCA can trigger a recapture of depreciation when you eventually sell the property, meaning you could owe more tax at that point. Many accountants recommend against claiming CCA on rental properties unless cash flow is a real concern. This is a decision worth discussing carefully before you file.
What You Cannot Deduct
It is just as important to understand what is off the table. Land does not depreciate, so you cannot claim CCA on the land portion of your property. Personal use expenses are not deductible. If you live in part of the property yourself, you must prorate your expenses based on the rental portion. Principal mortgage repayments are not deductible. And costs related to buying or selling the property, like land transfer tax or realtor commissions, are generally treated as capital costs rather than current deductions.
Record-Keeping: The Habit That Protects You
The CRA can audit rental income going back several years. The simplest way to protect yourself is to keep organized records throughout the year. A separate bank account for your rental income and expenses makes bookkeeping significantly easier. Save all receipts, invoices, and statements. Track your rental income by unit. If you ever face a review, having clean records makes the process far less stressful.
Under the Income Tax Act, you are required to keep supporting documents for at least six years from the end of the tax year they relate to. Many landlords keep them longer, especially those who own properties they plan to hold for decades.
Ontario-Specific Considerations
Ontario landlords operating under the Residential Tenancies Act have some unique situations worth noting. Costs related to Landlord and Tenant Board (LTB) hearings, including filing fees and any legal representation, may be deductible as expenses incurred to earn rental income. If you are dealing with an above-guideline rent increase application or a dispute with a tenant, document those costs carefully.
HST is another area to watch. Most residential rental income is exempt from HST in Ontario, which means you generally cannot claim HST input tax credits on expenses related to residential rentals. Commercial properties are treated differently. If you own both, your accountant needs to track this separately.
Working With a Property Manager Makes Tax Time Easier
One of the less obvious benefits of working with a professional property management company is the paperwork they handle on your behalf. At Blue Anchor Property Management, we provide landlords with clear, organized summaries of income received and expenses paid throughout the year. When your accountant sits down to prepare your return, everything is already in order. That saves time, reduces errors, and means fewer missed deductions.

Frequently Asked Questions
Can I deduct expenses if my rental property has no income for part of the year?
Generally yes, as long as the property was available for rent and you were actively trying to rent it. Expenses during a vacancy period are typically still deductible, but you should document your efforts to find a tenant to support your claim.
Can I deduct travel expenses to visit my rental property?
If you travel to your rental property to manage or maintain it, those travel costs may be deductible. If you drive, you would track your mileage and apply the CRA's prescribed rate. Keep a log of your trips and their purpose.
What happens if my rental expenses exceed my rental income?
A rental loss can generally be applied against your other sources of income, which reduces your overall tax bill. However, the CRA will look closely if you report rental losses year after year. They want to see a reasonable expectation of profit from your rental activity.
Do I need to register for HST as a residential landlord in Ontario?
For most residential rentals, no. Long-term residential rentals are exempt from HST, so you do not charge HST on rent and are not required to register. Short-term rentals (under one month) are treated differently and may require HST registration if you exceed the $30,000 threshold.
Is there a difference between repairs and capital improvements?
Yes, and it matters. A repair restores something to its original working condition and is fully deductible in the current year. A capital improvement upgrades or extends the life of the property and must be added to the property's cost and depreciated through the CCA system over time.
