Ontario's Residential Tenancies Act: The Basics
In Ontario, the relationship between landlords and tenants is governed by the Residential Tenancies Act (RTA), administered by the Landlord and Tenant Board (LTB). The RTA sets out the rights and obligations of both parties, and it is heavily tenant-protective compared to many other Canadian provinces. GTA landlords who don't understand their rights — and obligations — risk costly mistakes.
Rent Increase Rules in Ontario
For rental units first occupied before November 15, 2018, Ontario's rent increase guideline applies. In 2025, the guideline is set annually by the provincial government (historically 1.5%–2.5%). Landlords must provide 90 days' written notice of a rent increase using the proper N1 form, and cannot increase rent more than once every 12 months.
Units first occupied on or after November 15, 2018 are exempt from rent increase guidelines — landlords can increase rent by any amount with proper 90-day notice. However, the notice requirements still apply, and tenants retain the right to dispute increases they believe are improper.
Right of Entry: When Can You Enter Your Rental Property?
Ontario landlords cannot enter a rental unit whenever they choose. Under the RTA, landlords must provide 24 hours' written notice before entering, except in genuine emergencies (fire, flood, immediate safety risk). The notice must specify the reason for entry and the time of entry (between 8am and 8pm). Failure to follow proper entry procedures is a violation of the tenant's right to quiet enjoyment — a serious issue that can result in LTB complaints.
Maintenance Obligations: What Landlords Are Legally Required to Do
Ontario landlords are legally required to maintain their rental properties "in a good state of repair and fit for habitation." This obligation exists regardless of what a lease says, and regardless of a tenant's consent. Key areas include:
- Heating (must be maintained at minimum 20°C from September 1 to June 15)
- Plumbing, electrical, and structural systems
- Pest control
- Exterior grounds and common areas
- Appliances provided at the start of the tenancy
Tenants who experience maintenance issues can file T6 applications at the LTB, potentially resulting in rent abatements and repair orders. Proactive property maintenance is both a legal requirement and a sound investment strategy.
