How to Become a Landlord in Ontario: Complete 2026 Guide

Why Ontario Is Different

Ontario landlord law is genuinely distinct from the rest of Canada and dramatically different from the US. The Residential Tenancies Act gives Ontario tenants some of the strongest legal protections in North America: rent control on older units, a specialized tribunal (the LTB) for all disputes, mandatory notice forms, strict deposit rules, and lengthy eviction timelines when things go wrong.

This isn't reason to avoid becoming a landlord — Ontario also has strong rental demand, a large investor community, and solid long-term appreciation in most markets. But it does mean you need to know the rules before you start. Landlords who learn the RTA on the fly often make procedurally defective errors that cost them months of time at the LTB.

Step 1 — Choose the Right Property

The property you buy determines almost everything about your experience as a landlord. Consider:

For first-time landlords, a duplex or single-family home with a legal secondary suite is generally the right starting point. It lets you learn the RTA, develop landlord systems, and make your first mistakes at a scale that's manageable.

Step 2 — Run the Numbers (Ontario-Specific)

Most rental property calculators are built for the US market. They miss Ontario Land Transfer Tax, the GTA municipal surtax, CMHC insurance premiums (if less than 20% down), and CRA's specific rules for rental income reporting on the T776.

For any Ontario property, you need to model:

• Ontario LTT — provincial land transfer tax. First-time buyers of principal residences get a rebate up to $4,000, but investment properties do not.
• GTA municipal surtax — if buying in Toronto, add the municipal LTT on top of provincial LTT.
• CMHC insurance — if putting less than 20% down, the premium (0.6%–4% of the mortgage) is added to your mortgage principal.
• Realistic vacancy allowance — budget for 4–8% vacancy (roughly 3–4 weeks per year per unit) unless you have evidence of unusually strong local rental demand.
• Maintenance reserve — budget 1% of property value per year for maintenance and capital reserves. On a $600,000 property, that's $6,000/year or $500/month.

Step 3 — Understand Your Financing Options

Your financing structure depends on whether you'll live in the property:

• Owner-occupied (1–4 units): Minimum 5–10% down, CMHC-insured mortgage available. Rental income may be partially used to qualify for a larger mortgage.
• Pure investment property: Minimum 20% down, no CMHC insurance available, typically higher interest rates than owner-occupied.

Work with a mortgage broker who has experience with Ontario investment properties. They can help you understand how lenders calculate rental income offsets for qualification and which lenders are most favourable for your situation.

Step 4 — Know Your Legal Obligations Before You Start

Before your first tenant moves in, understand these core legal obligations:

• You must use the Ontario Standard Form of Lease for all new residential tenancies. Custom leases are not permitted. If asked, you must provide a signed copy within 21 days.
• You can only collect last month's rent as a deposit. No security deposits, pet deposits, or damage deposits are permitted.
• You must pay interest on the last month's rent deposit annually at the Ontario rent increase guideline rate (2.1% in 2026).
• You must maintain the unit in a good state of repair under section 20 of the RTA — regardless of what the tenant knew when they moved in.
• You must never interrupt vital services (heat, electricity, water) — even if the tenant owes rent.
• Rent increases require 90 days' written notice on the official N1 form, and are limited to the guideline percentage for units first occupied before November 15, 2018.

Step 5 — Screen Tenants the Right Way

Tenant screening in Ontario is governed by the Ontario Human Rights Code (OHRTO) — not just by what's practical. There are 17 protected grounds under the Code, and asking questions that discriminate on any of those grounds during screening can result in an HRTO complaint against you.

You can legally ask about:

• Employment status and income
• Rental history and landlord references
• Credit history (with the applicant's written consent)
• Number of occupants (to assess whether unit size is appropriate)

You cannot ask about or discriminate based on: race, ancestry, place of origin, colour, ethnic origin, citizenship, creed, sex, sexual orientation, gender identity, age, marital status, family status, disability, or the receipt of public assistance.

Step 6 — Sign the Lease and Collect the Deposit

Use the current Ontario Standard Form of Lease, downloaded from ontario.ca. Complete all sections carefully — see our Standard Form of Lease Guide for a section-by-section breakdown. Add any property-specific terms in Section 15 (pet policy, smoking, guest parking rules).

Collect last month's rent at signing. Issue a written receipt that states the amount collected and that it is a last month's rent deposit. Record the date — this is the start date for your annual interest obligations.

Step 7 — Complete the Move-In Process

The move-in inspection is one of the most important steps that new landlords skip. Without a documented move-in condition report, you cannot prove what condition the unit was in when the tenant moved in — and therefore cannot successfully claim for tenant-caused damage at the end of the tenancy.

• Complete the inspection with the tenant present
• Document the condition of every room, appliance, fixture, wall, floor, and ceiling
• Take photographs or video — date-stamped
• Have both parties sign the inspection report
• Keep a copy — you'll need it at move-out

Provide the tenant with keys and any parking or access fobs. Confirm contact information for maintenance requests. Set up a simple system for receiving and tracking maintenance requests in writing.

Ongoing Obligations

Once the tenancy is active, your ongoing obligations include:

• Maintaining the unit in a good state of repair and responding to maintenance requests promptly
• Paying annual interest on the last month's rent deposit
• Following the proper notice procedure (N1 form, 90 days, guideline rate) before any rent increase
• Reporting rental income on your T776 each tax year — even if the rental results in a loss
• Renewing HRTO-compliant screening practices for any new tenants
