Ontario Form N10: Agreement to Increase Rent Above the Guideline

N10 is a voluntary written rent-increase agreement for qualifying capital work or new/additional services. It is not an ordinary N1 rent-increase notice or an L5 application for an LTB-approved increase.

This guide explains Form N10; only the PDF issued by Tribunals Ontario is the official form. Use the current PDF for any actual notice or agreement.

When can N10 be used?

The landlord and tenant can agree to an increase above the provincial guideline because the landlord has completed or will complete capital work, or will provide a new or additional service. Both parties must agree; a landlord cannot unilaterally issue an N10. An N10 generally requires at least 12 months since the tenancy began or the last rent increase.

How much can the rent increase?

The agreed increase cannot exceed the relevant annual guideline plus 3 percentage points. For example, Ontario’s 2026 guideline was 2.1%, so an eligible N10 increase taking effect in 2026 could be at most 5.1% (not an extra 3% of the increase). The 2027 guideline is 1.9%; always use the guideline for the year the increase takes effect.

Complete the form, field by field

1. Names: include all tenants and landlords, including mailing addresses, and identify the rental unit.
2. New rent: write the exact total amount, whether it is monthly/weekly, and the date the new rent begins.
3. Work or service: specify the real capital work or added service, what will be done and when. Attach details if needed; do not just write “upgrades.”
4. Dates: the agreed increase cannot start until at least six calendar days after the agreement is signed, and the ordinary 12-month rule still applies.
5. Signatures: both landlord and tenant sign and date; everyone keeps a copy.

Can the tenant cancel?

Yes. The tenant may cancel the N10 agreement by giving written notice to the landlord within five calendar days after signing. Keep proof of delivery. If not cancelled, this agreement takes the place of a normal rent-increase notice; the landlord does not need a separate N1 for this agreed increase.

What if the promised work never happens?

If the landlord fails to do the work or add the agreed service, the tenant may apply to the LTB to invalidate all or part of the amount above the guideline. The N10 explains a two-year application deadline from the date the rent increased under the agreement. This is different from disputing an ordinary above-guideline L5 order.

Do not use this simplified example where an exemption or specialized rent regime changes the ordinary rules. Check whether rent control applies to the unit.

Common mistake to avoid

The N10 is voluntary, not a demand. Before signing, confirm both the 12-month rule and the five-day cancellation window.
