Renting a home in Ontario comes with its own set of legal terms and industry-specific language. Whether you’re reviewing a lease, speaking with a landlord, or filing an application with the Landlord and Tenant Board, it’s essential to understand the vocabulary being used. This glossary provides plain-language definitions of the most commonly used terms in Ontario’s rental system.

Accessibility modifications: Changes to help tenants with disabilities. Landlords must accommodate up to the point of undue hardship.

Arrears: Rent that is overdue.

Assignment: A permanent transfer of the tenancy to another person, with landlord consent.

Bad faith: Giving a notice without a genuine reason. A T5 application can address it.

Co-signer or guarantor: Someone who agrees to be responsible if the tenant doesn’t pay.

Common areas: Shared spaces, such as lobbies and laundry rooms. Landlords maintain these.

Deposit: In Ontario, a rent deposit of up to one month’s rent, plus a refundable key deposit. Damage deposits are not permitted.

Essential or vital services: Heat, hydro, fuel, and hot and cold water. Landlords cannot withhold them.

Eviction: Ending a tenancy by a Board order, enforced by the Sheriff.

Fixed-term lease: A lease for a set time, usually 12 months. It normally continues month to month afterward.

Human Rights Code: Ontario law that bans discrimination in housing on protected grounds.

Human Rights Tribunal of Ontario: The tribunal that hears discrimination applications.
