Rental income is fully taxable, but the CRA also allows landlords to deduct a genuinely wide range of expenses against that income. Here's a practical rundown of what's actually deductible — and a few things landlords commonly get wrong.
The Core Categories of Deductible Expenses
Mortgage interest — the interest portion of your mortgage payments on a rental property is deductible, though the principal portion is not.
Property taxes on the rental property.
Insurance premiums, including standard landlord insurance and any group policy you carry specifically for the rental.
Repairs and maintenance — genuine repairs (fixing what's broken) are deductible in the year you pay for them, though this is an area where landlords commonly make a costly mistake (more on that below).
Property management fees, including a professional property manager's monthly fee, tenant placement fees, and any other management-related costs.
Utilities, if you pay them on the tenant's behalf rather than the tenant paying directly.
Advertising costs for finding a tenant.
Legal and accounting fees related to the rental — including costs for preparing leases, pursuing an LTB matter, or having your rental income properly filed.
Condo fees, if applicable, for a rental unit in a condominium.
The Repair vs. Improvement Distinction (Where Landlords Get Tripped Up Most)
This is genuinely one of the most common — and most expensive — mistakes we see: confusing a current expense (fully deductible the year you incur it) with a capital expense (which must be depreciated over time through Capital Cost Allowance, not written off all at once).
A repair restores something to its original condition — fixing a broken window, patching a leaking roof, repairing a malfunctioning appliance. Generally a current expense, fully deductible now.
An improvement enhances the property beyond its original condition — a full kitchen renovation, replacing a roof entirely rather than patching it, adding a new structure. Generally a capital expense, deducted gradually over years through CCA.
Landlords who deduct a major renovation in full the year they pay for it, assuming it counts the same as a repair, risk a reassessment down the road. If you're unsure which category a specific expense falls into, this is exactly the kind of question worth confirming with an accountant before you file, not after.
Capital Cost Allowance (CCA): Use With Caution
CCA lets you deduct a portion of the building's value (not the land) over time — but claiming CCA has a specific consequence worth understanding: it can trigger recapture and capital gains implications when you eventually sell the property. Many accountants advise against claiming CCA on a rental property you intend to hold long-term specifically because of this future tax consequence. This is a genuinely case-by-case decision worth discussing directly with an accountant familiar with rental property taxation.
What Non-Resident Owners Need to Know Additionally
If you're a non-resident owner, your rental income is subject to a separate withholding and reporting regime — generally a flat withholding tax on gross rental income, unless you file a Section 216 election to be taxed on net rental income instead, which allows you to claim these same deductions against your income. Given how different non-resident tax obligations are from a standard domestic landlord's filing, this is an area where professional guidance genuinely pays for itself.
What Good Record-Keeping Actually Looks Like
Keep every receipt and invoice, organized by property if you own more than one rental.
Separate current expenses from capital expenses as you incur them, rather than sorting through a year's worth of receipts at tax time.
Track mileage and any home-office-related costs if you self-manage and do legitimate work related to the property from home.
Get a clear monthly and annual expense breakdown if you use a property manager — this is something we provide as a standard part of our service, specifically so it can go straight to your accountant.
The Bottom Line
The list of deductible rental expenses is genuinely broad, but the repair-versus-improvement distinction and the CCA decision are exactly where landlords most commonly make costly mistakes. A conversation with an accountant familiar with rental property taxation before you file is almost always worth the cost.
