If you operate residential rental properties in Ontario, the Landlord and Tenant Board (LTB) “N-forms” are the foundational legal documents of your business. With very few exceptions, you cannot change rent, alter a lease agreement, or address a tenancy issue without serving or signing one of these standardized forms.
Because the LTB operates on a strict zero-tolerance policy for technical mistakes, using the wrong form—or filing it with an incorrect notice window—will result in your case being completely thrown out.
To help you navigate the regulatory landscape under the Residential Tenancies Act (RTA), this master directory indexes all 15 active LTB N-forms, broken down cleanly by their functional purpose.
1. Notices Governing Rent Rates and Financial Changes
These forms are strictly operational, handling how much a tenant pays and ensuring any financial changes comply with provincial rent controls.
- N1 (Notice of Rent Increase): The standard form used to increase a tenant’s rent once every 12 months, restricted to the annual Ontario rent guideline cap. Requires a strict 90-day notice period.
- N2 (Notice of Rent Increase – Exempt Units): Used for newer rental units first occupied for residential purposes after November 15, 2018. While these units are exempt from provincial percentage caps, landlords must still provide the full 90 days’ notice.
- N3 (Notice for Care Home Charges): Specifically for retirement or assisted-living facilities to separate physical rent costs from care services and meal provisions.
- N10 (Agreement to Increase Rent Above Guideline): A voluntary agreement where a tenant agrees to a rent hike above the guideline (up to 4%) in direct exchange for a major unit upgrade or a brand-new amenity (e.g., adding an air conditioner).
- N14 (Notice of Rent Reduction): Issued to a tenant if their rent is being lowered, which automatically occurs if municipal property taxes drop significantly or a standard utility service is discontinued.
2. Fault-Based Eviction Notices (Tenant Default)
When a tenant violates the terms of their lease agreement or the RTA, landlords must use “for cause” notices. Most of these forms grant a correction window where the tenant can resolve the issue to void the notice.
- N4 (Notice for Non-Payment of Rent): The most common form in Ontario, giving a tenant 14 days to pay outstanding rental arrears or face an LTB application.
- N5 (Notice for Damage, Disturbance, or Overcrowding): Used for behavior-based issues, noise complaints, or property damage. The first notice gives the tenant 7 days to correct the issue.
- N6 (Notice for Illegal Acts): Issued if a tenant commits an illegal act or runs an illegal business on the rental property premises.
- N7 (Notice for Serious Problems): An urgent, non-correctable 10-day notice used if a tenant causes massive structural damage, poses an immediate physical safety risk, or manufactures illegal drugs.
- N8 (Notice for Persistent Late Rent): Used when a tenant eventually pays their rent, but has established a documented, chronic pattern of paying late. This takes effect at the end of the lease term.

3. No-Fault Eviction Notices (Landlord Portfolio Use)
These notices are issued when a landlord needs to reclaim a unit for reasons completely unrelated to tenant behavior. They often carry mandatory financial compensation penalties that must be paid to the tenant.
- N12 (Notice for Purchaser’s or Own Use): Used when the property owner, a close family member, or a home buyer intends to move into the rental unit for at least one full year. Requires one month’s rent compensation.
- N13 (Notice for Demolition, Conversion, or Major Repairs): Issued if the building is being demolished, converted to commercial use, or requires renovations so extensive that they require a building permit and complete vacant possession.
4. Tenant-Issued Notices and Mutual Agreements
Tenants have their own legal forms to assert their rights, break a lease, or coordinate a clean exit with a property manager.
- N9 (Tenant’s Notice to End the Tenancy): The formal written notice a tenant provides to a landlord when they intend to move out voluntarily at the end of their lease term.
- N11 (Agreement to End the Tenancy): A dual-signed, voluntary contract where both the landlord and tenant mutually agree to dissolve the lease on an agreed-upon date, completely bypassing standard notice timelines.
- N15 (Tenant’s Notice – Domestic or Sexual Violence): Urgent protective notice that allows a tenant to break a fixed-term lease with only 28 days’ notice if they or a child residing with them are facing safety risks or abuse.
Best Practices for Successful Filing
Whether you are executing an annual rent increase via an N1 or repossessing a unit using an N12, the LTB treats administrative errors with absolute rigidity. Always implement these safeguards:
- The “Clear Days” Rule: When calculating notice windows, never count the day you deliver the notice or the final termination date itself. Missing the count by a single day renders the form invalid.
- Verify Consent for Email: LTB forms can only be served via email if your tenant has explicitly opted-in by signing the electronic service clause in their Ontario Standard Lease.
- Complete a Certificate of Service: The moment an N-form leaves your hands, fill out a Certificate of Service (Form CS). This document is your only legal proof to the LTB that the tenant actually received the notice.
