What an N5 notice covers

The N5, formally "Notice to End your Tenancy For Interfering with Others, Damage or Overcrowding," is the form a landlord uses in Ontario to address certain kinds of tenant conduct that fall short of an illegal act but still cause real problems. Unlike the N4 for unpaid rent, the N5 has a distinctive two-step structure built into the RTA: in many cases, a tenant can void the notice entirely by fixing the problem within a set window, but that option disappears if the same kind of problem happens again within six months.

The three grounds: interference, damage, overcrowding

An N5 can generally be used for three different categories of issues, and a single notice may cite more than one:

Substantial interference with the reasonable enjoyment of the landlord or other tenants — for example, ongoing excessive noise, harassment of other tenants, or disruptive behaviour affecting the residential complex.
Wilful or negligent damage caused by the tenant, someone the tenant permitted in the unit, or a guest — ordinary wear and tear does not count, but damage beyond that generally does.
Overcrowding beyond what health, safety, or occupancy standards allow for the unit.

Because these grounds can overlap with more serious situations, it is worth understanding how the N5 differs from other notices — an illegal act (like drug trafficking from the unit) generally falls under an N6, and conduct that is severe enough to seriously endanger someone's safety may instead warrant an N7, which does not offer the same voiding option. Our notices and forms hub compares the full set of notice types.

The voidable first N5

For a first-time issue of this kind in the preceding six months, the RTA generally gives the tenant seven days from the day the N5 is given to correct the behaviour — for example, stopping the disruptive conduct, repairing or paying for the damage, or reducing occupancy to a compliant level. If the tenant corrects the problem within that seven-day window, the notice becomes void, and the landlord cannot use it as the basis for an LTB application.

Key point

The seven-day correction period only works for a genuinely first-time issue within the last six months. Tenants should treat a first N5 seriously — correcting the problem promptly and, ideally in writing, documenting that it was corrected, since this protects against a dispute later about whether the issue was actually fixed in time.

A repeat within six months cannot be voided

If the tenant has already received an N5 for the same type of conduct within the previous six months and does it again, the notice generally cannot be voided by correcting the behaviour — the landlord may proceed directly toward an LTB application once the notice period passes, even if the tenant tries to fix the problem again. This distinction is the core design of the N5: Ontario law gives tenants one meaningful chance to correct a first-time problem, but not unlimited chances for repeat conduct.

Common misconception

Some tenants assume that fixing the problem always stops an eviction application, regardless of how many times it has happened. That is not correct — once a genuine repeat within six months is established, correcting the issue again generally does not void the notice, though it may still be relevant to what happens at an LTB hearing.

What happens next: the L2 application

If the N5 is not voided — either because the correction period passed without the problem being fixed, or because it was a non-voidable repeat notice — the landlord's next step is generally to file an L2 application with the Landlord and Tenant Board (LTB). This is the standard application used for most notices other than non-payment of rent. As with any LTB matter, filing the application does not end the tenancy on its own; the LTB will generally schedule a hearing where both sides can present evidence, and only a Board order can authorize an eviction. Our LTB hearing guide covers what to expect at that stage, and our evictions in Ontario guide explains the enforcement steps that follow an order.

How to respond to an N5

A tenant who receives an N5 should first identify which ground (or grounds) it cites and whether it is described as a first notice or references an earlier one. If it is a first-time issue, acting quickly within the seven-day window — and keeping evidence of having done so — is generally the most direct way to resolve the situation. If the notice is disputed, for example because the tenant believes the conduct did not happen or was not as described, or the "damage" is actually ordinary wear and tear, that dispute is generally best raised at the LTB hearing following an L2 application, ideally with the help of a paralegal or lawyer.

Landlords, for their part, should keep clear documentation of the specific incident, dates, and any communication with the tenant, since these details generally matter both in deciding whether the notice was properly issued and later at any LTB hearing.
