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

Filling out an N4 looks simple — but small errors get LTB applications dismissed every day. Follow these six steps to complete yours correctly. (New to the form itself? Start with the complete N4 form guide.)

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: the correct notice period for your rent frequency and service date (Bill 60-aware), plus any service-method days. Use the free N4 termination-date calculator to check a date yourself.

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

Top Mistakes to Avoid

The quick list — the full breakdown of the five N4 mistakes covers each one in detail:

• 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.
