Ontario Landlord Tenant Board Forms: Which LTB Form Do You Need?

The Two Categories of LTB Forms Landlords Use

The Landlord and Tenant Board publishes dozens of forms, but as a landlord you only deal with two categories: notice forms (what you serve on the tenant) and application forms (what you file with the Board). Mix them up and the Board dismisses your case before you say a word.

Notice forms start with "N" — N4 for rent arrears, N5 for conduct problems, N12 for personal or purchaser use, N13 for demolition or major renovation. You serve these on the tenant to start the process. They are a statutory prerequisite, not an eviction order.

Application forms start with "L" — L1 to collect arrears after an N4, L2 for everything else (conduct, personal use, renovation), L3 when the tenant agreed to leave on a Form N11 but didn't. You file these with the Tribunal after serving the notice and waiting through the required period.

Notice Forms: Matching Your Situation to the Right N-Form

Here's what each notice covers under the Residential Tenancies Act, 2006 (rules as at October 2026, including Bill 60 amendments in force September 21, 2026):

Form N4 — Non-Payment of Rent: Your tenant hasn't paid rent. The notice period is 7 days regardless of tenancy type. Only lawful rent can appear on the N4 — no utility disputes, maintenance costs, or late fees. The tenant can void the notice by paying the full arrears before you file the L1.

Form N5 — Interference, Damage, or Overcrowding: Noise complaints, property damage, or overcrowding. The first notice gives the tenant 7 days to fix the problem; a second N5 within 6 months carries no cure period. If you live in the same building and it has three or fewer units, N7 is also available for interference with your reasonable enjoyment.

Form N6 — Illegal Activity or Misrepresentation: Specified drug-related illegal acts get a 10-day notice. Other illegal acts and income misrepresentation in rent-geared-to-income housing get a 20-day notice, with no cure period. A 14-day second N6 notice may be used in the circumstances described by the LTB instructions when the first notice was an N5 the tenant voided by correcting the problem.

Form N7 — Causing Serious Problems: The tenant's actions or omissions seriously impair someone's safety. N7 is also available for certain serious problems, including interference with a resident landlord's enjoyment in a building with three or fewer units. Ten-day notice, no cure.

Form N8 — Persistent Late Payment: The tenant pays rent more than 7 days late at least three times in six months. Sixty-day notice for monthly tenancies, and the termination date must land on the last day of a rental period.

Form N12 — Personal or Purchaser Use: You, a close family member, or a buyer with a signed Agreement of Purchase and Sale needs to move in. Since September 21, 2026, landlord own-use has a 60-day compensated path or a 120-day compensation-free path; purchaser use remains at least 60 days with one month's compensation.

Form N13 — Demolition, Conversion, or Major Repair: You need vacant possession for work that requires a building permit. For extensive repairs or renovations, the N13 must include a qualified-person report. The notice period is 120 days. Toronto and Hamilton municipal renovation licences may apply to renovations that require the tenant to vacate.

Application Forms: Filing with the Board

Once you've served the right notice and the notice period has passed, you file an application:

• Form L1: Arrears only (follows N4). Filing fee is $186 online through the Tribunals Ontario Portal, or $201 by mail. Attach your N4, Certificate of Service, and an L1/L9 Update Form showing the current balance.
• Form L2: Everything else — conduct, personal use, renovation, persistent late payment. Same fees. Attach the relevant notice and Certificate of Service; for N12 cases, include the required affidavit, and for extensive N13 repairs or renovations, the qualified-person report.
• Form L3: When a tenant agreed to leave (Form N11 or N9) but hasn't vacated. Same fees.

The Form Most Landlords Forget: Certificate of Service

When you apply to the LTB, you need a completed Certificate of Service showing how and when the notice was served. It is signed by whoever delivered the document. Without it, you may be unable to prove service.

Where to Download Current Forms

All prescribed forms are free on the Tribunals Ontario website. The critical word is "current" — using an outdated version of any form is a procedural defect that can sink your application. Download fresh copies each time.

LTB staff can answer questions about which form to file, but they are legally barred from advising you on which notice to serve, how to calculate your notice period, or whether your situation fits a particular ground.

Choosing the Right Path for Your Situation

If you're a private Ontario landlord facing a tenancy that needs to end, the form selection is the first step — and getting it wrong means restarting the entire process. Our Ending a Tenancy in Ontario guide walks through the full decision tree: which form fits your situation, how to calculate the notice period correctly (including the +5 day mail buffer), and how to complete the Certificate of Service so your application holds up at the Board.
