Which Landlord and Tenant Board Form Do You Need? A Guide by Situation

The Landlord and Tenant Board form you need depends on what you are trying to do. A notice, such as the N4 for unpaid rent or the N1 for a rent increase, goes to your tenant. An application, such as the L1 or L2, goes to the Board. Match your situation in the table below, then download the current version from the LTB's forms page.

Notice or application: the two kinds of LTB forms

Landlord and Tenant Board (LTB) forms fall into two groups, and mixing them up is a common early mistake.

• Notices (N forms) go to your tenant. You do not file them with the Board. You give the notice, keep a copy and keep proof of how and when it was given.
• Applications (L, A and T forms) go to the Board. L forms are for landlords, T forms are for tenants and A forms can be used by either side.

Most eviction routes have two steps: a notice first, then an application if the tenant does not comply or leave. The LTB says the application you can file depends on the notice you served, and that some notices expire if the application is not filed in time. Our overview of LTB applications shows how the pieces fit together.

Which Landlord and Tenant Board form fits your situation

Find your situation in the first column. Each row names the usual notice and application. Read the LTB's instructions for each form before you act. They are linked next to every form on the LTB site.

Other forms cover narrower cases, such as the L8 when a tenant changed the locks, the A2 for a sublet or assignment and the A1 on whether the Act applies.

Rent increase forms: N1, N2, N3, N10 and L5

For a rent increase the standard notice is the N1. Related notices exist for special cases: the N2 for a unit that is partly exempt from the guideline, the N3 for care services and meals charges, and the N10 for an agreement to increase rent above the guideline. A landlord who wants the Board to approve an above-guideline increase files the L5. It goes by email, mail, courier or ServiceOntario, not the portal.

Ontario's rules say the notice must be written, in the proper form and given at least 90 days before the increase takes effect. In most cases 12 months must also have passed since the last increase or the start of the tenancy. Our guide to the N1 walks through filling it out. D&D Property Management's lease management work tracks those dates for owners.

N4, N12 and L1: the forms landlords ask about most

L1. The L1 is the application to evict a tenant for non-payment of rent and to collect the rent owed. You need a copy of the N4 you gave, a certificate of service showing how and when you gave it, and the fee. You wait until the day after the N4's termination date. You cannot use it once the tenant has moved out, which is what the L10 is for. Our L1 walkthrough covers the form in detail.

N4. The N4 is the notice to end a tenancy early for non-payment of rent and the first step toward an L1. For notices given on or after September 21, 2026, the LTB says the termination date must be at least 7 days after you give the notice, down from 14. The LTB publishes the N4 as a PDF with instructions. Be wary of a homemade or third-party template. The instructions warn that a notice completed wrongly may not be valid and you may have to start over.

N12. The N12 ends a tenancy because the landlord, a purchaser or a family member requires the unit. You do not file it with the LTB. You give it to the tenant by hand, in the mailbox, under the door, by courier or by mail, never by posting it on the door, and you keep a copy. Its termination date must be at least 60 days after you give it and fall on the last day of the rental period or fixed term. If the tenant does not leave, you file an L2 with a copy of the N12 and a certificate of service, no later than 30 days after the termination date. The N12 instructions are the place to confirm who qualifies and what compensation applies.

Outdated versions: check before you download or reuse a form

Forms change with the law. On September 21, 2026 the LTB released an updated N4 and replaced the N5, N6, N8, N12, N13, L1, L2, L9, L10 and T5. It says previous versions of the forms on that list will no longer be accepted as of November 30, 2026. The updated N12 instructions, for instance, now describe a 120-day option on compensation. Good habits:

• Download from the LTB's forms page each time. Do not reuse a PDF you saved last year or a copy from a template site.
• Right-click the form name, choose Save link as, and open the saved file in Adobe Reader. The LTB says not to complete forms in your browser because some browsers will not let you save them.
• Check the updated date on the form's instructions.
• If you already served a notice on an older version, ask the LTB or a lawyer or paralegal what that means for your situation. We cannot tell you.

Where to download LTB forms and how to submit them

Every current form and its instructions sit on the LTB's Forms, Filing and Fees page at tribunalsontario.ca. If you are unsure which one fits, the Navigate Tribunals Ontario tool asks questions about your situation and points you to the right information. Then choose how to file.

• Tribunals Ontario Portal for the L1, L2, L3, L4, L9 and L10. It guides you step by step and takes the fee by card.
• Email with online payment for the L6, L7, L8, A1, A2 and A4. You pay first, then email the form and receipt to ltbpayments@ontario.ca. The L5 has its own email steps. Never put card details in an email. The LTB deletes those applications.
• Mail, courier or a ServiceOntario centre that accepts LTB filings, for any application. Mail can mean processing delays.

LTB fees are non-refundable, so confirm the form before you pay. Our filing fees guide covers costs and timelines.

Landlord and Tenant Board form questions

What is the L1 form at the Landlord and Tenant Board?

The L1 is the Application to Evict a Tenant for Non-Payment of Rent and to Collect Rent the Tenant Owes. A landlord files it after giving an N4 and waiting past its termination date. It is filed with the LTB, either on the Tribunals Ontario Portal or by mail, courier or at a ServiceOntario centre.

How do I file an N12 form?

You do not file an N12 with the LTB. You give it to the tenant and keep a copy. If the tenant does not leave, you then file an L2 application with a copy of the N12 and a certificate of service, no later than 30 days after the termination date on the notice.

Is there an N4 notice template I can use instead of the LTB form?

Use the LTB's own N4. It is published as a PDF with instructions, and the instructions warn that a notice completed incorrectly may not be valid. A third-party template could be out of date, since the N4 was updated on September 21, 2026. Download the current version from the LTB site.

Can I still use an LTB form I saved last year?

Check first. The LTB replaced several forms on September 21, 2026, including the N4, N12, L1 and L2, and says previous versions will not be accepted as of November 30, 2026. Download a fresh copy from the forms page instead of reusing an old file.
