N4 vs N12 in Ontario: Which Eviction Notice Do You Actually Need?

By Solutions Property Management — Sat Jul 11 2026

We get this call a few times a month. A landlord is frustrated, the tenant situation has gone sideways, and the question is always some version of the same thing: "Which form do I serve?"

It matters more than most people think. The N4 and the N12 are not interchangeable. They solve completely different problems, they run on different clocks, and serving the wrong one is one of the fastest ways to lose weeks at the Landlord and Tenant Board.

Here is how to tell them apart without a law degree.

The short version

• N4 is for one thing only: the tenant owes you rent and has not paid it.
• N12 is for when you, a buyer, or a close family member genuinely intends to move into the unit.

If money is the issue, you are in N4 territory. If you need the unit back for personal use, that is an N12. Mixing them up is the classic mistake.

The N4: unpaid rent

The N4 is a Notice to End a Tenancy for Non-payment of Rent. You can serve it the day after rent is late, and the termination date you write on it has to give the tenant at least 14 days (7 days for daily or weekly rentals).

The part landlords forget: the N4 is not an eviction. It is a warning with a deadline. If the tenant pays everything they owe before that date, the notice is void and the tenancy carries on like nothing happened. That is by design under the Residential Tenancies Act.

Only if the deadline passes and the balance is still outstanding can you file an L1 application with the Board to actually end the tenancy and collect the arrears. Get the arrears math wrong on the N4 and adjudicators will often toss it, so double-check every dollar and every month.

The N12: you or family need the unit

The N12 is a Notice to End a Tenancy Because the Landlord, a Purchaser or a Family Member Requires the Unit. This is the form for:

• You moving in yourself
• Your spouse, child, parent, or your spouse's child or parent moving in
• A buyer of the property (or their close family) moving in, as part of a sale

The N12 gives the tenant 60 days notice, and the termination date has to land on the last day of a rental period. So if rent runs the first to the end of the month, your end date is the last day of a month, at least 60 days out.

There are two more strings attached that catch people:

1. One month's rent compensation. You have to pay the tenant one month's rent (or offer another acceptable unit) on or before the termination date. 2. Good faith. The person named on the notice has to actually intend to live there for at least a year. If a tenant challenges the N12 and the Board decides you used it to flip the unit to a higher-paying renter, you can face serious penalties. Adjudicators take bad-faith N12s seriously.

A quick side-by-side

| | N4 | N12 | |---|---|---| | Reason | Unpaid rent | Owner or family use | | Notice period | 14 days (7 for weekly) | 60 days | | Can the tenant cancel it? | Yes, by paying in full | No | | Compensation owed | None | One month's rent | | Next step | L1 application | L2 application |

Where landlords go wrong

The most common errors we see are small and fatal:

• Wrong termination date (too soon, or not the end of a period)
• Arrears added up incorrectly on the N4
• No compensation paid on an N12
• Serving an N12 when the real goal is a rent bump

Any one of those can send you back to square one after a two- or three-month wait for a hearing. That is why the paperwork is worth slowing down for. A clean, correctly served notice is the difference between a case that moves and a case that dies on a technicality.

If you are staring at a late tenant or a unit you need back and you are not sure which form fits, that is exactly the kind of thing we handle every week. Our team serves these notices, files with the Board, and shows up to the hearing so you do not have to guess.
