Form N5 is Ontario’s notice for ending a tenancy early because of conduct, not rent: substantial interference with others, damage to the property, or overcrowding. A first N5 gives the tenant 7 days to correct the problem and void the notice, and its termination date must be at least 20 days after the notice is given.
That second chance is where landlords lose cases. Serve it with vague details, count the days wrong, or file too early, and the Landlord and Tenant Board (LTB) can dismiss the application. This guide covers the three reasons, the two versions of the notice, how to complete and serve it, and what happens next. It sits alongside our guide to the N4 notice and the LTB timeline for unpaid rent.
What is Form N5 used for?
The N5 covers three reasons, and only three. Each can be triggered by the tenant, another occupant of the rental unit, or a guest the tenant permits in the complex.
| Reason | What has to have happened | RTA section |
|---|---|---|
| 1. Interference | Conduct that substantially interferes with the reasonable enjoyment of the residential complex, or with a lawful right, privilege or interest of the landlord or another tenant. | Section 64 |
| 2. Damage | Undue damage to the rental unit or the residential complex, caused wilfully or negligently. Wear and tear is not undue damage. | Section 62 |
| 3. Overcrowding | More people living in the unit on a continuing basis than health, safety or housing standards required by law allow. | Section 67 |
Is it a first or a second N5?
The same form does two different jobs depending on whether the tenant has had an N5 in the past 6 months.
| First N5 | Second N5 (within 6 months) | |
|---|---|---|
| Termination date | At least 20 days after the notice is given | At least 14 days after the notice is given |
| Can the tenant void it? | Yes, by correcting the problem within 7 days | No |
| When can you file Form L2? | On or after day 8, if the notice was not voided | As soon as the notice is given |
A second N5 needs fresh conduct. Under section 68 of the RTA it is a further-contravention notice, and Interpretation Guideline 10 adds two limits: it cannot rest only on the same incidents listed in the first notice, and conduct from before the first notice’s 7-day correction window closed cannot support it. The new problem need not be the same type as the old one, and a second N5 can be given whether or not the tenant voided the first.
How does a tenant void a first N5?
By fixing the exact problem the notice describes, within 7 days after receiving it. What counts as a fix depends on the reason:
- Interference: stop the conduct or activity, or correct the omission the notice sets out.
- Damage: repair the damaged property, replace it if repair is not reasonable, pay the reasonable cost of repair or replacement, or make arrangements with the landlord to do one of those.
- Overcrowding: reduce the number of people living in the unit enough to comply with the standard the notice cites.
If the tenant corrects the problem, the notice is void and you cannot apply to the Board. That is the design of the form, not a loophole.
How is overcrowding measured?
Neither the RTA nor the form sets a persons-per-bedroom number. The test under section 67 is whether the number of people occupying the unit on a continuing basis contravenes health, safety or housing standards required by law.
Two consequences follow. Guests staying over are not occupants. And your notice has to name the law or by-law that sets the maximum and state it; on a first notice it also has to state the number the household must come down to. The LTB’s instructions tell landlords to ask the municipality which by-law applies.
How do you complete the notice so it holds up?
Work through the form’s checklist before serving. It reads like a list of reasons applications get dismissed, because it is one:
- Name every tenant in possession, spelled correctly, and give each tenant a copy. Name a subtenant or assignee where there is one. You do not name other occupants, such as children or guests.
- Give the complete address of the rental unit, with the unit identifier and postal code.
- Mark the reason or reasons, and mark the notice voidable (first) or non-voidable (second). It cannot be both at once, even across reasons.
- Write the Details section like evidence, not a complaint. Who did it, on what dates, at what times, what happened, who was affected. Attach extra pages rather than compressing months of incidents into two lines. For damage, give the repair or replacement cost, and say whether you know the incident date or only the discovery date.
- Sign and date it. An unsigned or undated notice may be invalid.
The details section does double duty: it tells the tenant exactly what to stop or fix inside the 7-day window, and it becomes the outline of your case at a hearing. Our guide to commonly damaged items in rental properties covers the wear-and-tear side of the damage question and how repair costs are valued.
How do you serve an N5, and what is the Certificate of Service?
The LTB’s instructions list the permitted ways: hand it to the tenant or an adult in the unit, leave it in the mailbox or where mail is delivered, slide it under the door or through the mail slot, fax it, or send it by courier, mail or Xpresspost. Posting it on the door is not allowed.
Your method sets the clock. Do not count the day you give the notice. Hand delivery and the mailbox count from the day given. Courier adds one business day. Mail adds five days. The instructions’ example: handed over on November 15, a first N5 can carry a December 5 termination date; mailed the same day, December 10.
After serving, complete a Certificate of Service. It states how and when the notice was given, and the server signs it. The certificate is filed with your L2 application, together with a copy of the notice, and at a hearing months later it is your proof of service.
What happens after you serve it? Form L2 and the hearing
The notice alone does not end the tenancy, and the termination date is not a move-out order. If the tenant stays, only the Board can terminate the tenancy, after a hearing.
On a first N5, you can file Form L2, the Application to End a Tenancy and Evict a Tenant, starting on the 8th day if the tenant has not voided the notice (section 70 bars filing during the 7-day window). On a second N5, you can apply as soon as the notice is given. Either way, section 69 sets the outer deadline: no later than 30 days after the termination date. Miss it and the notice is spent, however strong the conduct was.
The L2 filing fee is $201, or $186 through the Tribunals Ontario Portal.
At the hearing, you have to prove the claims in the notice and the application; the tenant can attend and dispute them. Dated notes, photographs, written complaints from other tenants, and repair invoices carry that proof. Two cautions: if the Board orders eviction, the tenant will likely be ordered to pay your filing fee; and even where a ground is proven, the Board can refuse or delay eviction under section 83. A valid notice gets you a hearing, not a guaranteed order.
When is the N5 the wrong form?
Three situations belong on Form N7, with a termination date as early as day 10 and no chance to void:
- Safety: an act or omission that seriously impairs the safety of any person in the residential complex (RTA section 66).
- Wilful damage: damage caused deliberately, where you can prove it (section 63). If you cannot prove deliberate damage, the N5 instructions say to use the N5, where negligence is enough.
- Interference in a small building where you live: substantial interference in a building of three or fewer units where the landlord also lives (section 65).
What are the mistakes that get N5s dismissed?
- Vague details. “Ongoing noise complaints” proves nothing. Dates, times, and what happened are the minimum.
- A termination date that is too early. Under 20 days on a first notice, under 14 on a second, or forgetting the extra days mail and courier add.
- Counting the day of service as day one.
- Filing the L2 inside the 7-day window on a first notice, or past the 30-day deadline after the termination date.
- Serving by an unlisted method, such as taping the notice to the door, or with no Certificate of Service to prove service.
- A second N5 built on the first notice’s incidents, or on conduct from inside its correction window.
- An overcrowding notice with no standard behind it: no law or by-law named, no maximum stated.
- Treating wear and tear as damage. Scuffs, tired paint and worn carpet are the cost of a tenancy, not undue damage, and leading with them weakens the real items.
What this guide can’t tell you
It cannot tell you whether your facts clear the bar. “Substantial” interference and “undue” damage are judgement calls the Board makes on the whole record, and relief from eviction under section 83 turns on circumstances no article can see. It cannot tell you how long a hearing will take, either: Board timelines move.
Handling an N5 yourself is reasonable. A landlord with one property, a good incident log, and the patience to read the form’s instructions twice can serve a clean first notice, and many first notices end the problem inside the 7 days. Management earns its keep on the paper discipline: logs, correct day counts, filing inside the deadline, and a hearing-ready file. That is the work RentSetGo Property Management does under its full-service property management in Ottawa, alongside the broader framework in our guide to landlord rights and responsibilities in Ontario.
The Bottom Line
The N5 is a correction notice first and an eviction tool second. Get the reason right (interference, damage, or overcrowding under sections 64, 62 and 67), respect the 7-day correction window, count to 20 or 14 days without counting the day you serve, and write the details like evidence. Most N5 files are lost on dates, details and service, not on the underlying conduct.
Frequently Asked Questions
How much notice does a first Form N5 give?
At least 20 days after the notice is given, not counting the day you give it. The tenant has 7 days after receiving it to correct the problem and void the notice. Served by mail, add 5 days for delivery before the 20 start counting.
Can a tenant void a second N5?
No. A second N5 rests on new conduct that arose more than 7 days and less than 6 months after a first N5. It cannot be voided, its termination date must be at least 14 days out, and the landlord can apply to the Board as soon as it is served.
When can a landlord file Form L2 after serving an N5?
On a first N5, on or after day 8, if the tenant did not correct the problem inside the 7-day window. On a second N5, as soon as the notice is given. Either way, the application must reach the Board no later than 30 days after the termination date in the notice.
How much does it cost to file an L2 application?
The current Form L2 fee is $201, or $186 through the Tribunals Ontario Portal. The Board will not process the application without it, and a fee waiver request is available if you cannot afford it.
Does an N5 end the tenancy on its own?
No. The notice starts the process; it does not end the tenancy or require the tenant to move out. If the tenant stays, the landlord applies to the Landlord and Tenant Board, and only the Board can order the tenancy terminated, after a hearing the tenant can dispute.
What counts as overcrowding under the N5?
More people living in the unit on a continuing basis than health, safety or housing standards required by law allow. Neither the Act nor the form sets a persons-per-bedroom number, so the notice has to name the law or by-law that sets the maximum and state that maximum.
What if the tenant seriously impaired someone’s safety?
That is not an N5 ground. Seriously impairing someone’s safety is section 66 of the Residential Tenancies Act, served on Form N7: termination date at least 10 days after the notice is given, and no opportunity to void it.
