How to Fill Out the N4 Form in Ontario (Step-by-Step)

Filling out the N4 form looks simple — but small errors get LTB applications dismissed every day. Follow these six steps to complete your N4 correctly.

1. 1

   Enter landlord information

   Provide the legal name of every landlord listed on the lease, along with a current mailing address and phone number. If a representative (paralegal, property manager) is signing, capture their LSUC number and firm details too.

2. 2

   Add tenant and property details

   List every adult tenant on the lease — exactly as their name appears on the lease. Then enter the rental unit address including unit number, city, province, and postal code.

3. 3

   Itemize the rent owing

   For each rent period that has unpaid amounts, enter the period start and end dates, the rent charged, and the amount paid. The N4 requires a row for each separate period — not a lump sum.

4. 4

   Choose service method and notice date

   Pick how you will serve the notice (hand, courier, or mail). The termination date is then auto-calculated by adding the minimum notice period (14 or 7 days — 7 for monthly and yearly N4s served on or after September 21, 2026 under Bill 60) plus any service-method adjustment.

5. 5

   Sign the form

   Type your name, draw a signature, or have a representative sign. The signature date must match or follow the notice date.

6. 6

   Review, pay, and download

Top Mistakes to Avoid

• Don't serve the N4 on the same day rent is due — wait until the next day.
• Don't lump multiple months into one rent period row.
• Don't forget to add the +5 days when serving by mail.
• Don't omit any tenant listed on the lease.
• Don't forget to keep a Certificate of Service for the L1 application.
