Ontario condo owners systematically under-claim rental expenses on their tax returns. Some of the misses are large — condo fees, professional management fees, mortgage interest. Some are small but compound — advertising, screening fees, banking charges. This is the working list.

Rental income from your condo is reported on Form T776 (Statement of Real Estate Rentals) and flows through to your personal return. You report gross rent received in the year, then subtract eligible expenses to arrive at net rental income (or loss).
Ontario condo rentals are typically considered rental income rather than business income — the distinction matters for tax treatment but rarely for individual condo investors.
CCA lets you deduct depreciation on the building (not the land) at 4% per year on a declining-balance basis. It's optional and worth thinking carefully about — claiming CCA can reduce current-year tax but recapture rules mean some of it is added back when you sell.
For owners planning to hold long-term, CCA may make sense. For owners likely to sell within 5–7 years, the recapture often eliminates the benefit. Talk to your accountant before claiming.
Routine repairs (replacing a broken faucet, patching drywall, fixing an appliance) are immediately deductible in the year incurred. Capital improvements (renovating the kitchen, installing new flooring throughout, replacing the HVAC) are capitalized and depreciated over time.
The CRA's distinction is roughly: does the work restore the property to its previous condition (repair) or improve it beyond that condition (capital)? Document accordingly.
Periods of vacancy are not automatically a problem for tax purposes — expenses during reasonable vacancy between tenants remain deductible. But extended vacancies, especially if the unit is not actively listed, can trigger CRA scrutiny over whether the property is actually held for rent or for personal use.
Document active marketing during vacancy: MLS listings, online ads, showings. The paper trail justifies the deduction.
Owners who claim cleanly at year-end have organized records: a rent ledger, condo fee statements, mortgage interest statements (T5008-equivalent), property tax bills, insurance invoices, and an itemized list of repairs and capital expenditures.
CentreKey owners receive a year-end statement bundle that compiles most of this automatically. The remaining items — mortgage interest, property tax — you provide. The whole package goes straight to your accountant.
