N10 Notice Ontario: Agreement to Increase Rent Above the Guideline

An N10 in Ontario is a voluntary written agreement between a landlord and tenant to raise rent above the province’s annual guideline, typically in exchange for completed capital work or a new service. It requires both signatures, at least 90 days’ notice before the new rent takes effect, and the increase is capped at the guideline amount plus 3%. Tenants can cancel within 5 days of signing.

Every year, Ontario sets a rent increase guideline — the maximum percentage most landlords can raise rent without going through a formal application. But there’s a lesser-known path that lets a landlord and tenant agree, together, to a bigger increase: the N10.

Because it’s a genuine agreement rather than a one-sided notice, the N10 works differently from almost every other LTB form. Here’s how it actually functions, and what both sides should watch for.

What Is an N10 Notice in Ontario?

The N10 is officially titled “Agreement to Increase the Rent Above the Guideline.” It’s authorized under section 121 of the Residential Tenancies Act, 2006 (RTA), and it allows a landlord and tenant to voluntarily agree to a rent increase larger than the annual guideline would otherwise permit.

Unlike a notice, the N10 is a contract. Both the landlord and the tenant must sign it, and if they do, it takes the place of a standard Notice of Rent Increase — the landlord doesn’t need to serve a separate N1 for the same increase.

When Can Landlords and Tenants Use an N10?

An N10 agreement is generally used in one of two situations:

• Capital work: The landlord has carried out, or agrees to carry out, significant capital expenditures on the building or unit — things like a new roof, updated plumbing, or major structural repairs.
• New or additional services: The landlord provides a new service the tenant didn’t previously have, such as air conditioning, parking, or additional appliances.

Some qualifying improvements don’t even require a written agreement under a separate set of rules — but for the standard N10 route, both a completed (or committed) qualifying project and mutual written consent are required.

N10 vs. N1: What’s the Real Difference?

The core distinction: an N1 is something a landlord can serve unilaterally within the guideline. An N10 requires the tenant’s active, informed agreement — and gives them a built-in right to change their mind shortly after signing.

How Much Can Rent Increase Under an N10?

The increase permitted under an N10 is capped at the annual guideline amount plus an additional 3%. For example, if the guideline for a given year is 2.5%, the maximum increase under an N10 agreement for that year would be 5.5%. This cap exists specifically to prevent capital-work agreements from becoming a workaround for unlimited rent increases.

What Must an N10 Agreement Include?

• Full names and addresses of all landlords and tenants involved.
• The rental unit’s address and the date the new rent takes effect.
• The new rent amount and payment frequency.
• A detailed description of the capital work or new/additional service, including specifics like items purchased, installation dates, and completion timelines.
• Signatures from both the landlord and tenant, along with the date signed and phone numbers for each party.

Because an N10 replaces the standard notice process entirely, an incomplete or vague description of the work can leave the agreement open to challenge later. Our Notice and Rent Rate service helps landlords draft an N10 that holds up if it’s ever questioned.

A Tenant’s Right to Cancel

Tenants who sign an N10 have a short window to change their mind: they can cancel the agreement by giving the landlord written notice within 5 days of signing. Once that window passes without cancellation, the agreement generally becomes binding, subject to the landlord actually completing the promised work or service.

If the agreement isn’t cancelled but the landlord never follows through on the capital work or new service, the tenant can apply to the LTB (using Form T4) and ask that all or part of the above-guideline increase be declared invalid.

What Happens After the N10 Is Signed?

• The agreement takes effect on the date specified, provided it’s at least 90 days after the agreement was made.
• If a separate N1 notice had already been served for the same rent period, it becomes void once the N10 is signed.
• The landlord should retain proof the work was completed or the service was provided, in case the increase is ever disputed.
• The tenant should keep a signed copy of the agreement along with any documentation about the promised work.

Common Mistakes With the N10 Agreement

• Setting the increase above the guideline-plus-3% cap
• Vague or incomplete descriptions of the capital work or new service
• Failing to get a genuine signature from every tenant on the lease
• Not giving the tenant the full 90 days’ notice before the new rent takes effect
• Landlords who collect the higher rent but never complete the agreed-upon work, exposing themselves to a T4 application

Getting any of these wrong can unwind an otherwise legitimate rent increase. Our landlord paralegal services in Toronto help landlords structure N10 agreements that are clear, fair, and enforceable.

Why Work With a Paralegal for Rent Increase Agreements?

Because the N10 is a negotiated agreement rather than a one-sided notice, both landlords and tenants benefit from having the terms reviewed before signing. A licensed paralegal can help with:

• Confirming the proposed increase falls within the guideline-plus-3% cap
• Drafting a clear, specific description of the qualifying work or service
• Advising tenants on whether an agreement is fair before they sign
• Filing or responding to a T4 application if the agreed-upon work is never completed

Frequently Asked Questions About the N10 Notice Ontario

Is a tenant required to sign an N10 agreement?

No. The N10 is entirely voluntary. A tenant who doesn’t want to agree to an above-guideline increase can simply decline to sign.

How much can rent increase under an N10?

The increase is capped at the annual guideline amount plus an additional 3% for that year.

Can a tenant cancel an N10 after signing?

Yes, within 5 days of signing, by giving the landlord written notice of cancellation.

What if the landlord doesn’t do the promised work?

The tenant can apply to the LTB using Form T4 to have all or part of the above-guideline increase declared invalid.

How much notice is required before the new rent takes effect?

At least 90 days from when the agreement is made, the same minimum that applies to a standard N1 notice.

What’s the difference between an N10 and an N1?

An N1 is a notice a landlord can serve on their own, capped at the annual guideline. An N10 is a mutual agreement that allows an increase above the guideline, capped at guideline-plus-3%, in exchange for capital work or a new service.

Do I need a paralegal to draft or review an N10 agreement?

It isn’t required, but given how easily a vague description of the work can lead to a later dispute, having a paralegal review the terms through our Notice and Rent Rate service is a smart safeguard for both sides.
