Tax Deductions for Ontario Landlords: What You Can Claim

Property Management in Ontario

Rental income is taxable, but rental property expenses are generally deductible — understanding the rules maximizes your after-tax returns.

Rental income from Canadian property is included in the landlord's personal income and taxed at their marginal rate. For landlords in Ontario, the combined federal-provincial marginal rate on rental income at the middle income level is approximately 43%. Maximizing deductible expenses directly reduces this tax burden.

Key Responsibilities and Best Practices

Mortgage interest (not principal) is deductible against rental income. This is one of the most significant deductions for leveraged landlords. Maintain accurate records of interest paid each year — your mortgage lender provides an annual statement showing principal and interest components.

Property taxes paid on the rental property are fully deductible in the year paid. For landlords who also receive property tax bills on their principal residence, maintaining separate records for the rental property's tax payment is necessary for accurate deduction.

How D&D Property Management Helps

Insurance premiums for the rental property are deductible in the year the premium applies. If you pay a multi-year premium in advance, it must be pro-rated across the years of coverage.

Repairs and maintenance expenses are deductible in the year incurred. This includes plumbing and heating repairs, appliance service, painting, minor fixture replacements, and similar ordinary maintenance costs. Capital expenditures — improvements that substantially extend the property's useful life or add a new asset — are not immediately deductible but can be claimed through capital cost allowance (CCA) over time.
