N4 and N12 Forms: Ontario Landlord Notice Requirements Explained

Ontario landlords use the N4 form to start the process when rent is late, and the N12 to reclaim a unit for personal or family use. An N4 can be served the day after rent is due; an N12 requires at least 60 days' notice and one month's compensation to the tenant.

Ontario landlords rely on two forms to handle the most common rental issues: the N4 when rent is late, and the N12 to reclaim a unit for the landlord’s or a family member’s own use. Both have strict notice, content, and delivery requirements, and small errors on either form cause real delays.

When can I serve an N4 form?

An N4 can be served the day after rent is due — a landlord doesn’t need to wait for a promise to pay or give a grace period before starting the process.

When rent is late, you can take action right away. Here’s what to do:

When to send the notice:

  • Send it the day after rent is due
  • Don’t wait for promises to pay
  • Start the process right away to protect yourself

How to fill out the form:

  • Write down all tenant names
  • Put in the full address
  • List the exact amount owed
  • Use the right delivery method

How does the N12 form work?

The N12 requires at least 60 days’ notice and one month’s compensation to the tenant, and it can only be used to move in the landlord or an eligible family member.

Sometimes a landlord needs the rental property back — maybe to move in themselves, or because their child needs a place to live. The N12 form handles this.

Important rules to know:

  • Give at least 60 days’ notice
  • Pay one month’s rent to the tenant
  • Make sure the person moving in is actually allowed under the notice
  • Follow the rules about who can live there afterward

What mistakes should I avoid on the N4 or N12?

The most common errors — wrong dates, missing tenant names, incorrect amounts, and improper delivery methods — are avoidable, but any one of them can cause significant delays.

Many landlords make simple mistakes that cause big delays:

  • Wrong dates on forms
  • Missing tenant names
  • Wrong amounts listed
  • Incorrect delivery methods

Where can Ontario landlords get help with these forms?

Frequently asked questions

When can I serve an N4 form in Ontario?
The day after rent is due — you don't need to wait for a promise to pay or give the tenant extra time first. Starting the process immediately is what protects a landlord's position if the arrears continue.
How much notice do I need to give for an N12?
At least 60 days. The N12 is used when a landlord (or an eligible family member) needs to move into the rental unit themselves, and the notice period is longer than the N4's because it isn't tied to a tenant default.
Who can move into a unit under an N12 notice?
The landlord, or their children, parents, or spouse. The person moving in has to be someone the notice actually permits — using an N12 for anyone outside that list is one of the mistakes that causes delays or a dismissed application.
Do I have to pay the tenant if I use an N12?
Yes — one month's rent in compensation is required when serving an N12. This is a mandatory part of the process, not optional or negotiable.
Do I need to wait for a tenant's promise to pay before serving an N4?
No. Landlords can and should send the N4 the day after rent is due rather than waiting on a promise to pay, since delaying only pushes back the rest of the arrears process.
What are the most common mistakes landlords make with N4 or N12 forms?
Wrong dates, missing tenant names, incorrect amounts owed, and using the wrong delivery method. Any of these can cause real delays in an already slow process, so accuracy on the form matters as much as timing.
