Ontario LTB Forms for Landlords: How the Notices, Applications and Requests Fit Together

All of the notices, applications and procedural forms in an Ontario rental dispute governed by the Residential Tenancies Act, 2006 (RTA) come from the Landlord and Tenant Board (LTB). The list beneath this guide links to a separate page for each one, setting out its purpose, its deadlines, how to complete it and the errors that lead to a refusal or dismissal. Start here to see how they connect: a wrong form at the outset is hard to fix later in a case.

Quick reference

The five groups

N notices

One party gives an N notice to the other. On the rent side there is the N1, the N2 for units exempt from the rent increase rules, the N3 for care homes, and the N10, which records an agreement to raise rent above the guideline. To end a tenancy, a landlord uses: unpaid rent, N4; overcrowding, damage or interference, N5; persistent late payment and the other end-of-term grounds, N8; use of the unit by the landlord or a buyer, N12; and conversion, repairs or demolition, N13. Tenants give their own notice on the N9, and an N11 records an agreement by both sides that the tenancy will end. Section 43 of the RTA requires a notice of termination to be on the approved form, to identify the unit, to give the termination date and to be signed.

L applications

An L application asks the Board to make an order for eviction, rent, other money or a rent increase above the guideline. The ones landlords file most are the L1 for non-payment of rent and the L2, which covers most other eviction grounds and money owed by a tenant who is still living in the unit. An L3 or L4 can be granted with no hearing at all. The L9 and L10 recover money while leaving the tenancy in place, and the L5 asks for an above-guideline increase.

T applications

Tenants file T applications, for example the T2 on tenant rights, the T6 on maintenance and the T5 alleging a notice was given in bad faith. As the respondent, a landlord should know what each one claims.

A applications

Either party can bring the A1 (does the RTA apply?), the A2 (sublet or assignment) or the A4 (varying a rent reduction).

Procedural forms

These move a file along once it is open. They include the Payment Agreement, the L1/L9 Information Update and the Certificate of Service; motions like the S3; and requests to amend, to reschedule, to extend or shorten time, or to review an order.

The notice comes before the application

On most eviction grounds the sequence is set. You serve the N notice, wait out the notice period and any period the tenant has to fix the problem, and only then file the L application that matches. Section 69 of the RTA says an eviction application has to rest on a notice of termination and, apart from non-payment of rent, must be filed no later than 30 days after the termination date in the notice. The LTB's Rules of Procedure, at Rule 6, set out timing errors that lead to a refused application, one example being an L1 filed on or before the termination date in the N4. No landlord's notice of termination is needed to start an L3, L4, L9 or L10.

Choosing your form in four steps

1. Begin with the result you are after: getting the unit back, unpaid rent, some other sum, a higher rent, or a decision on whether the Act applies at all.
2. Identify the legal ground and the notice that goes with it. Every form page lists its RTA section.
3. Confirm the deadlines before you serve. Notice periods cannot be lengthened or shortened by the LTB (O. Reg. 516/06, s. 56).
4. Work from the official instructions, since Board staff compare what you file against them.

Where to file, and outdated versions

Six landlord applications (L1, L2, L3, L4, L9, L10) are filed online through the Tribunals Ontario Portal, at a reduced fee. Most other applications are sent by email, mail or courier, or filed through ServiceOntario (details are on the LTB filing fees page).

On September 21, 2026, to implement Bill 60 and Bill 97, the LTB swapped in new versions of ten forms: N5, N6, N8, N12, N13, L1, L2, L9, L10 and T5. On the same date it released a new N4 with a 7-day notice period and a new form, "Issues a Tenant Intends to Raise at a Rent Arrears Hearing." According to Tribunals Ontario, older versions of the replaced forms stop being accepted as of November 30, 2026. That statement does not name the N4 or the Issues form, so it is not confirmed whether the cut-off reaches them. Download a new copy each time instead of relying on one you saved.

Frequently asked questions

Does an N4 or N12 get filed with the Board?

No, it is served on the tenant. The LTB only sees it later, attached to your application along with the Certificate of Service.

Is last year's downloaded form still usable?

Not for the ten forms replaced on September 21, 2026 (listed above); the Board stops taking their older editions as of November 30, 2026. Any other form, the new N4 among them, should still be downloaded fresh.

How does an L1 differ from an L9?

The L1 is based on an N4 and both ends the tenancy and recovers rent. The L9 recovers rent only, from a tenant who remains in the unit.
