Ontario LTB arrears: the N4 to L1 process step by step

The Ontario Landlord and Tenant Board's arrears process is procedurally demanding. Most failed applications are not dismissed because the landlord had the wrong facts — they're dismissed because a form was served incorrectly, the ledger included non-rent charges, or the Information Update wasn't filed five days before the hearing. This guide walks through every required step so you arrive at the hearing with a clean file.

Step 1: Serve the N4 Notice

The N4 (Notice to End a Tenancy Early for Non-Payment of Rent) is the prerequisite for any L1 application. You can serve it the day after the missed due date. There is no waiting period for serving the N4 — if rent is due on the 1st and it hasn't arrived by the 2nd, you can serve the notice.

N4 rules that commonly cause defective notices

• The amount on the N4 must be rent only — no NSF fees, late fees, maintenance deductions, or any other charges. Including non-rent amounts makes the N4 defective.
• The termination date must give the tenant at least 14 days for a monthly tenancy (7 days for weekly/daily). The date must be the last day of a rental period — typically the last day of the month.
• Tenant names must match the lease exactly. A wrong name gives the tenant grounds to challenge.
• The current lawful rent must be accurate. If you entered an incorrect rent amount at any point, the N4 figures may not match the lease.

What happens if the tenant pays in full before the termination date

If the tenant pays the total arrears on the N4 in full before the termination date, the N4 becomes void. You cannot file an L1 on that notice. If the same tenant falls behind again the following month, you need to serve a fresh N4.

Step 2: File the L1 Application

The L1 (Application to Evict a Tenant for Non-payment of Rent and to Collect Rent the Tenant Owes) can be filed the day after the N4 termination date passes, provided the tenant has not paid in full. You cannot file before the termination date. There is no upper deadline for filing, but delays add to the arrears and push your hearing date further out.

• Filing fee: $186 online through the Tribunals Ontario Portal; $201 by mail, courier, or in person. The fee is recoverable in your order if you win.
• Required at filing: the served N4, a completed Certificate of Service, a current rent ledger, and your lease.
• File online where possible — the portal processes applications faster than paper.

Step 3: Serve the L1 on the tenant

The LTB will issue a Notice of Hearing after your L1 is accepted. You are required to serve a copy of the application and the Notice of Hearing on the tenant. Document how you served it — hand delivery, mail, or authorized courier — and complete a Certificate of Service. Keep this on file. The LTB may ask for it.

Step 4: File the L1/L9 Information Update

This is the step that trips up the most landlords. At least five business days before your hearing, you must file an L1/L9 Information Update form with the LTB and serve it on the tenant. The Information Update tells the board the current arrears balance — accounting for any payments the tenant made after you filed the L1. If you miss this deadline, the LTB may refuse to hear your case entirely and you could lose the filing fee.

Set a calendar reminder the moment you receive your hearing date. Five business days is tighter than it sounds: if your hearing is on a Thursday, you need to file by the previous Thursday at the latest, accounting for any non-business days.

What to bring to the hearing

• A printed, organized rent ledger showing every charge and payment from the start of the tenancy (or at least 12 months back if the tenancy is long).
• A copy of the lease.
• Proof of service for the N4 and the L1/Notice of Hearing.
• The filed L1/L9 Information Update.
• Any written communication with the tenant about the arrears (texts, emails, letters).
• If applicable: the signed PAD agreement, payment receipts, bank records confirming NSF events.

Realistic timelines for 2026

As of 2026, LTB hearings for L1 applications are scheduled approximately two to three months after filing. From the N4 service date to enforcement of an eviction order, the full process typically takes four to six months. If the tenant does not vacate by the order date and you need to involve the Court Enforcement Office (sheriff), add another three to six weeks. These timelines are reasons to start the process promptly — each month of delay adds to your arrears and extends your timeline.

Upcoming changes: Bill 60

Ontario's Bill 60 proposes to shorten the N4 notice period from 14 days to 7 days for monthly tenancies. As of this writing, those amendments have not been proclaimed in force. The government and Tribunals Ontario are preparing for implementation. Watch the Tribunals Ontario website for updates before serving any N4 — the applicable notice period may change with minimal advance public notice.
