The Ontario N5 Notice, Explained: Damage, Disturbance or Overcrowding
The N5 is served when a tenant substantially interferes with the reasonable enjoyment of the landlord or other tenants, wilfully or negligently damages the unit, or allows more people to live in the unit than health and safety standards permit. Unlike the N4, a first N5 gives the tenant a chance to fix the problem.

Notice period
First N5: termination date at least 20 days after service. Second N5 within six months: at least 14 days.
Can the tenant cancel it?
On a first N5 the tenant has 7 days to correct the behaviour (stop the disturbance, repair or pay for the damage, reduce the occupancy) — do that and the notice is void. A second N5 within six months has no correction window.
Compensation
None required for this notice.

When to Use the N5
The N5 is the right notice when the tenant is disturbing others, damaging the unit, or overcrowding it. Typical situations:
A tenant repeatedly disturbs neighbours — noise, smoke, harassment.
The tenant or their guests have damaged the unit or building.
More people are living in the unit than is safe or permitted.
How the N5 Process Works
Each step matters — a mistake at any stage, especially the notice itself, can reset the whole process and cost you weeks or months.
Document the problem thoroughly
Dates, times, descriptions, photos, repair estimates, and any complaints from other tenants. Vague allegations fail; specific evidence wins.
Serve the first N5
The termination date must be at least 20 days out. The notice must describe exactly what the tenant did and what they must do to correct it.
Watch the 7-day correction window
If the tenant fixes the problem within 7 days, the N5 is void. If they do not, the notice stands and you can move to the LTB.
Serve a second N5 or file an L2
If the tenant corrects but re-offends within six months, a second N5 (no correction window) can be served. Otherwise, file an L2 within 30 days of the termination date.
Attend the LTB hearing
Present your documented evidence. A paralegal can establish the pattern of conduct and rebut the tenant's explanations.

Mistakes That Void a N5
Describing the problem too vaguely — the N5 must state specific incidents and dates.
Missing the 7-day correction window rules, or treating a first N5 like it has none.
Waiting too long: an L2 must be filed within 30 days of the termination date.
Thin or missing evidence — photos, logs, and third-party complaints matter enormously.
