The Ontario Standard Lease, Explained

Before you hand over a deposit, you should understand the document you're about to sign. In Ontario, most landlords are legally required to use the Ontario Standard Lease — a plain-language government form designed to make tenancies fair and clear. This guide walks through what the standard lease covers, the rights it protects, and your options if a landlord skips it.

Key takeaways

• The Ontario Standard Lease is mandatory for most residential tenancies.
• It's a plain-language form that sets out rent, parties, term and the rules of the tenancy.
• Any term that conflicts with the Residential Tenancies Act is not enforceable.
• If your landlord doesn't provide one, you can demand it in writing — and may be able to withhold rent if they still refuse.
• Rent increases on the lease still follow the 90-day notice and guideline rules.

What is the Ontario Standard Lease?

The Ontario Standard Lease is a fill-in-the-blanks form created by the provincial government. Since it became mandatory, most landlords renting a home in Ontario must use it for new written tenancy agreements. It replaced the patchwork of homemade and template leases that often buried unfair clauses in fine print.

The goal is simple: every tenant in Ontario should be able to read and understand their lease. It's written in plain language and lays out the essentials in a consistent order, so you know exactly what you're agreeing to.

It's the law for most rentals

The standard lease is required for most residential tenancies under the Residential Tenancies Act. A few tenancy types are exempt, but the typical apartment, house, condo or basement unit is covered.

What's inside the lease

The standard lease captures the core terms of your tenancy. Key sections include:

• The parties — the legal names of the landlord and every tenant.
• The rental unit — the address and what's included (parking, storage, utilities).
• The term — fixed-term (e.g. one year) or month-to-month.
• Rent — the amount, the due date, and how it's paid.
• Services and utilities — who pays for heat, water, hydro, internet and the like.
• Rules and key terms — any additional terms, which must follow the law.

It also includes a built-in explanation of the rights and responsibilities both sides have under Ontario law, so the rules aren't a mystery.

Why it protects you

The biggest protection isn't on the form itself — it's the principle behind it. Any clause that tries to remove a right the Residential Tenancies Act gives you is not enforceable, even if you signed it. A lease can't legally let a landlord enter without notice, skip required repairs, or raise rent outside the rules.

For example, your lease can't override the rent rules: increases still require 90 days' written notice on Form N1, can only happen once every 12 months, and — for units first occupied on or before November 15, 2018 — are capped at the annual guideline (2.1% in 2026). See how much a landlord can raise rent for the details.

Read additional terms carefully

Landlords can add their own terms in the standard lease, but those terms still have to obey the law. If something looks like it strips a right — such as 'no LTB applications' or a blanket 'no guests' rule — it likely isn't enforceable.

What if your landlord won't provide one?

If your tenancy requires a standard lease and you didn't get one, you have leverage. The law gives tenants a process:

1. Ask in writing for the Ontario Standard Lease.
2. If the landlord doesn't provide it within the time the law allows, you may be able to withhold one month's rent.
3. If they still don't provide it after that, you may not have to repay that withheld month.

Even without a written lease, you're still a tenant with full rights under the RTA — verbal and informal tenancies are still protected. If a dispute develops, the Landlord and Tenant Board can step in.

Signing a lease vs buying

A standard lease gives you clear, legally backed terms — one of renting's real advantages. Still, many tenants reach a point where buying starts to make more financial sense. Weigh it with renting vs buying a home in Canada and the rent vs buy calculator.
