Landlord and Tenant Board Forms: A Step-by-Step Map for Landlords and Tenants

In Ontario, the Landlord and Tenant Board (LTB) supplies the forms that landlords and tenants use when a rental dispute arises under the Residential Tenancies Act, 2006 (the RTA). Some forms are used mostly by landlords, some by tenants, and some by either side. Below this guide is the full list, and every form has its own page walking through what it does, when it is due, how each part is completed and which slips cause trouble. Start here to see how the pieces connect.

The five groups at a glance

Who uses each group, and for what

N notices: one side tells the other

A notice passes directly between the parties. It is not an application.

• Raising the rent: the standard notice is the N1. Care homes use the N3, units outside the rent increase rules use the N2, and the N10 is a signed agreement to exceed the guideline.
• Ending a tenancy:
• unpaid rent: N4
• damage, overcrowding or interference: N5
• paying late again and again, or other grounds tied to the end of a term: N8
• the landlord or a purchaser wants to live there: N12
• conversion, demolition or repairs: N13
• Endings that start with agreement or with the tenant: both sides sign an N11 when they agree on a move-out; a tenant who wants to leave gives an N9.

Section 43 of the RTA sets the basics for any notice of termination: it has to be on the approved form, name the unit, give the termination date and carry a signature.

L applications: a landlord asks for an order

Here the landlord is asking the Board for an order: possession of the unit, unpaid rent, another sum of money, or permission to raise rent past the guideline.

• Unpaid rent: L1.
• Most other eviction grounds, or money from a tenant who has not moved out: L2.
• No hearing needed in many cases: L3 and L4.
• Money only, with the tenancy continuing: L9 and L10.
• Rent above the guideline: L5.

T applications: a tenant asks for an order

Examples are the T2 (tenant rights), the T5 (a notice given in bad faith) and the T6 (maintenance). Tenants file them; landlords respond to them, so both sides benefit from knowing what they cover.

A applications: open to either side

The A1 asks whether the RTA applies at all, the A2 deals with a sublet or assignment, and the A4 asks to vary a rent reduction.

Procedural forms: keeping a file on track

Think of these as the paperwork between the start and the end of a case. Proof of delivery goes on a Certificate of Service. Other examples are the Payment Agreement, the L1/L9 Information Update, motions like the S3, requests to move a hearing date or change a time limit, and requests to correct an order or to have an order reviewed.

The usual sequence: notice, wait, then apply

For most eviction grounds, a landlord follows the same three steps:

1. Serve the right N notice on the tenant.
2. Let the notice period pass (plus any window the tenant is given to correct things).
3. File the L application that pairs with that notice.

Section 69 of the RTA requires an eviction application to rest on a notice of termination. Unless the ground is unpaid rent, the filing window closes 30 days after the notice's termination date. The LTB's Rules of Procedure list, in Rule 6, timing mistakes that get an application refused. One example: an L1 filed on the N4's termination date or earlier. Four landlord applications skip the notice of termination altogether: L3, L4, L9, L10.

If you are a tenant holding an N notice, this sequence tells you what normally comes next: the matching L application, filed with the LTB.

Four steps to the right form

1. Name the result you are after. Do you want the unit back, money, an increase, or a decision about whether the Act covers the tenancy?
2. Match it to a legal ground and its notice. Every form page identifies the RTA section behind it.
3. Check the timing before you serve or file. The Board cannot stretch or shrink a notice period (O. Reg. 516/06, s. 56).
4. Open the official instructions and follow them. Filings are checked against those instructions by Board staff.

Filing checklist and the November 30, 2026 cut-off

• Portal forms: six landlord applications (L1, L2, L3, L4, L9, L10) are filed online, at a reduced fee, using the Tribunals Ontario Portal.
• Other applications: most go by email, mail, courier or ServiceOntario. Amounts are set out in the guide to LTB filing fees.
• PDF forms: save the file first, then complete it in Adobe Reader; browsers handle these forms poorly.
• Fresh copies: download a new copy every time instead of reusing a saved one.

Bill 60 and Bill 97 led the LTB to swap out ten forms on September 21, 2026. They are the L1, L2, L9, L10, N5, N6, N8, N12, N13 and T5. Two more arrived the same day: a new N4 (its notice period is 7 days) and a new "Issues a Tenant Intends to Raise at a Rent Arrears Hearing" form. Tribunals Ontario says the Board will refuse earlier versions of the ten replaced forms from November 30, 2026. Neither the N4 nor the Issues form appears in that statement, so nobody can yet say for certain whether the cut-off covers them.

Common questions

Does an N4 or N12 notice get sent to the LTB?

No. The tenant receives it. A copy reaches the Board only if the landlord files an application, with a Certificate of Service included.

Is a form I saved last year still good?

Not if it is one of the ten replaced in September 2026 (L1, L2, L9, L10, N5, N6, N8, N12, N13, T5). Those older copies are refused starting November 30, 2026. For everything else, the new N4 included, download the current version to be safe.

How is an L1 different from an L9?

An L1 follows an N4 and can lead to eviction plus an order for the rent owed. An L9 asks only for the rent, and it is used while the tenant remains in the unit.
