Ontario LTB · Notice

N5: Notice to End Tenancy for Interfering with Others, Damage or Overcrowding

Used when a tenant substantially interferes with the reasonable enjoyment of others, wilfully or negligently damages the unit, or allows more people to occupy the unit than standards permit.

How the N5 Works

  • First N5: termination date at least 20 days after service; the tenant has 7 days to correct the behaviour and void the notice.
  • Second N5 (within 6 months but at least 7 days after the first): termination date at least 14 days after service — no correction window.
  • Document every allegation thoroughly: dates, descriptions, photos, and estimated repair costs.
  • If the tenant does not correct the issue (or it's a second N5), file an L2 application — no later than 30 days after the termination date.

Fixed-Fee Help — No Hourly Billing

OLH handles the N5 on transparent fixed-fee rates (quoted in your free consultation, plus taxes and disbursements). Legal Guarantee clients pay nothing extra — every notice, filing, and LTB hearing is included at $199/month.

Approved Methods of Service

Invalid service is one of the most common reasons notices fail at the LTB. Approved methods:

MethodEffective date of service
Handed to the tenant (or an adult in the unit)Same day
Placed in the mailbox or mail slotSame day
Slid under the doorSame day
CourierFirst business day after sending
Regular mail5 days after mailing (add 5 days to notice period)
EmailDay sent — only with written consent in the lease

Not valid: taping to the door, leaving with a neighbour, posting in the building, text message, or voicemail. Always complete a Certificate of Service the day you serve.
