A rental property can build long-term wealth, but in Ontario it is a business with real obligations. This guide covers the upside, the downside and the rules every GTA landlord should know in 2026.
The advantages
- Tenants pay down your mortgage. Each month of rent builds equity, even if cash flow is small.
- Long-term price growth. Over decades, GTA property has tended to rise with population and limited land, although 2022 to 2025 showed prices can also fall for years.
- Deductible expenses. Mortgage interest, property tax, insurance, repairs and management fees can be deducted from rental income.
- Leverage. A 20 per cent down payment controls a much larger asset.
The disadvantages
- Cash flow is tight. Many GTA condos bought at 2022 prices rent for less than they cost to carry.
- Tenant disputes take time. Landlord and Tenant Board cases for non-payment or possession can take months.
- Rent increases are limited. See the rules below.
- It is not liquid. Selling takes time and costs commission, legal fees and possibly a mortgage penalty.
- Capital gains tax applies when you sell, unlike your principal residence.
Ontario rules every landlord should know
Rent control. The 2026 rent increase guideline is 2.1 per cent. It applies to most units first occupied for residential use on or before November 15, 2018. Units first occupied after that date are exempt from the guideline. Either way, you can raise rent only once every 12 months, with at least 90 days’ written notice on the proper form.
Standard lease. Most residential tenancies in Ontario must use the provincial standard lease form.
Deposits. You can collect a rent deposit of no more than one month’s rent (or one period’s rent) and must use it for the last month. Damage deposits are not allowed.
Short-term rentals. In Toronto, short-term rentals are only allowed in your principal residence, so a dedicated investment property cannot legally operate as one. See our Toronto short-term rental guide.
Second units. Basement apartments must meet the Ontario Building and Fire Codes, and Brampton and Mississauga require them to be registered.
Condo or house for a rental?
Condos are easier to manage and attract young professionals, but condo fees and special assessments eat into returns, and many buildings have more investor units than owners. Freehold homes with a legal basement unit often produce better cash flow because two rents cover one mortgage, but you handle all maintenance. More in our guide to buying a house or a condo.
Run the numbers first
Before you buy, estimate rent from recent leases in the building or street, then subtract mortgage payments at today’s rate, property tax, insurance, condo fee, a vacancy allowance of at least one month a year and a repair reserve. If it only works with rising prices, read the investing mistakes to avoid.
