In Ontario, dealing with the Landlord and Tenant Board can feel intimidating, especially when a single wrong form can delay your case or derail it entirely. Many landlords and tenants search for “LTB forms” because they need answers quickly and cannot afford to guess. When your housing, income, or property is on the line, paperwork stops being routine and starts feeling personal.
This guide breaks down the complete list of Ontario LTB forms and explains exactly when to use each one. Instead of scanning government pages or relying on advice that may be outdated, you will find clear, practical explanations in one place. We also highlight common mistakes that cause delays, rejections, or unnecessary stress, so you know what to avoid before filing anything.
Whether you are issuing an eviction notice, responding to an application, or applying for a rent increase, choosing the right LTB form matters more than most people realize. This resource is designed to help both landlords and tenants move forward with clarity, confidence, and fewer surprises when navigating the Ontario Landlord and Tenant Board system.
Why Ontario LTB Forms Confuse So Many People
If Ontario LTB forms feel confusing, you are not alone. Most people encounter them only when something has already gone wrong. Missed rent, unresolved repairs, noise complaints, or an unexpected notice can all push landlords and tenants into unfamiliar territory fast.
One of the biggest challenges is the language. LTB forms are written in legal terms that do not always match everyday meaning. Words that seem simple can carry very specific legal definitions, and misunderstanding them can completely change the outcome of a case. On top of that, there are dozens of different LTB forms, many of them similar in name but very different in purpose. Choosing the wrong one is easier than people expect.
Another issue is that LTB forms are procedural, not flexible. A small mistake like using the wrong form, serving it incorrectly, or missing a deadline can delay a case by months or cause it to be dismissed altogether. That pressure creates real anxiety, especially for people dealing with financial stress or housing uncertainty.
Forms also change over time. Many people rely on outdated versions they find online, not realizing the LTB may no longer accept them. Without clear guidance, it is easy to feel stuck, frustrated, and worried about making a mistake that cannot be undone.
How Ontario LTB Forms Work
Ontario LTB forms are standardized documents designed to guide landlord and tenant disputes through a formal process. Each form has a specific role. Some are notices that must be served before anything else can happen. Others are applications that officially bring a matter before the Landlord and Tenant Board.
The process usually starts with serving the correct notice, followed by filing an application if the issue is not resolved. Some LTB forms are filed online, while others can be submitted by mail. Certain applications require a filing fee, which must be paid before the case moves forward.
Once a form is filed, the other party is notified and given the opportunity to respond. In many cases, the LTB schedules a hearing where both sides present evidence. Timelines vary depending on the form and the issue involved, which is why accuracy from the start matters so much.
LTB forms are not just paperwork. They set legal timelines, define rights, and shape what the Board can and cannot consider. Understanding how the system works helps landlords and tenants avoid delays, missed steps, and unnecessary disputes.
LTB Forms Used by Landlords
N4 – Notice to End a Tenancy for Non-Payment of Rent
The N4 is one of the most commonly used Ontario LTB forms. It applies when a tenant has not paid rent on time. This notice tells the tenant exactly how much is owed and gives them a clear opportunity to pay before the landlord takes the next step.
For most tenancies, tenants have 14 days from the date the N4 is served to pay the outstanding rent. If they pay in full within that period, the notice becomes void and the tenancy continues.
The N4 must be completed carefully. The amount owing must be accurate, and the notice must be served properly. Proof of service is critical. If the tenant disputes the notice, the landlord must be prepared to show rent records and payment history.
An N4 alone does not end a tenancy. If rent remains unpaid, the landlord must file an L1 application with the LTB to move the process forward.
N5 – Notice to End a Tenancy for Interfering With Others or Damage

The N5 is used when a tenant’s behavior interferes with others or causes damage to the property. Common examples include ongoing noise complaints, damage beyond normal wear and tear, or actions that disrupt other tenants.
This form requires detail. Landlords must clearly describe what happened, when it happened, and how it affected others or the property. General statements are not enough. Documentation such as photos, written complaints, or incident logs can make a major difference.
After receiving an N5, the tenant usually has 7 days to correct the behavior. If the issue continues or happens again, the landlord may proceed with an L2 application.
Because disputes around behavior can escalate quickly, following the correct process from the start is essential.
N6 – Notice to End a Tenancy for Illegal Acts
The N6 is used in serious situations involving illegal activity at the rental property. This can include violence, drug-related activity, or other criminal acts.
This form carries higher risk and higher scrutiny. Allegations must be supported by clear evidence. Suspicion or hearsay is not enough. Police reports, incident records, or other reliable documentation are often necessary.
Timelines for the N6 can be shorter, and the consequences more immediate. Because of this, mistakes with this form can have serious legal consequences for both landlords and tenants. Careful preparation is critical before serving or filing anything related to an N6.
N7 – Notice to End a Tenancy for Serious Problems
The N7 is used when there are serious issues that affect health or safety, or when a tenant has seriously impaired the safety of others. This is not for minor concerns.
Landlords must clearly explain the nature of the problem and why it rises to a serious level. Evidence is often required, especially if the matter proceeds to the LTB.
The notice period depends on the situation, and the form must be served correctly. If the issue is not resolved, the landlord may move forward with an application to the Board.
N8 – Notice to End a Tenancy at the End of Term
The N8 is used to end a tenancy at the end of a fixed term or rental period. In most cases, no reason is required, but the notice must meet strict timing rules.
The end date must be clear and accurate. If the notice is late or the date is wrong, the N8 may be invalid. Tenants still have rights during this process, and misunderstandings often arise when communication is unclear.
Confirming delivery and keeping records helps avoid disputes later.
N12 – Notice to End a Tenancy for Landlord’s Own Use
The N12 applies when a landlord, or a close family member, intends to move into the rental unit. This form is closely monitored by the LTB.
Landlords must provide proper notice and compensation where required. They must also genuinely intend to occupy the unit. Tenants have the right to challenge an N12 if they believe it is being used improperly.
Because misuse of this form can lead to penalties, accuracy and honesty are essential.
N13 – Notice to End a Tenancy for Demolition, Conversion, or Repairs
The N13 is used when major work requires a tenant to move out. This includes demolition, conversion to another use, or extensive repairs that cannot be done while the unit is occupied.
The notice period is longer, and landlords must explain the scope of the work clearly. Permits and plans are often required. Tenants have the right to dispute the notice and, in some cases, the right to return after the work is complete.
This is one of the most complex LTB forms and should never be rushed.
L1 – Application to Evict a Tenant for Non-Payment of Rent
The L1 is filed after an N4 when rent remains unpaid. This application formally asks the LTB to order an eviction and possibly repayment of rent.
Landlords must provide accurate rent records and proof that the N4 was served correctly. The tenant is notified and may respond or attend a hearing.
The outcome depends heavily on documentation and timing.
L2 – Application to End a Tenancy and Evict a Tenant
The L2 is used for reasons other than non-payment, such as ongoing behavior issues or serious breaches of the tenancy agreement.
Landlords must show that proper notices were served and that reasonable steps were taken before filing. Even then, eviction is not automatic. The LTB weighs evidence and circumstances carefully.
LTB Forms Used by Tenants

T1 – Tenant Application for a Rebate of Money the Landlord Owes
The T1 form is used when a tenant is owed money by their landlord. This often includes illegal charges, rent overpayments, or costs the tenant covered because repairs were not completed. To file a strong application, tenants must provide clear evidence such as receipts, bank records, or written communication.
Once submitted, the landlord is notified and allowed to respond. The Landlord and Tenant Board reviews the information and may schedule a hearing. Filing the T1 early and keeping organized records improves the chances of a successful outcome.
T2 – Application About Tenant Rights
The T2 form applies when a landlord violates a tenant’s legal rights. Common issues include harassment, illegal entry, or interference with reasonable enjoyment of the unit. Tenants must clearly explain what happened and which rights were violated.
Supporting evidence such as emails, photos, or witness statements is critical. After filing, the landlord can respond and the LTB may hold a hearing. Tenants should file within deadlines and keep copies of all documents.
T3 – Tenant Application for a Rent Reduction
The T3 form allows tenants to request a rent reduction when the value of the rental unit has decreased. This may happen due to unresolved maintenance issues or reduced services. Tenants must clearly explain why the rent is no longer justified.
Evidence such as maintenance requests, photos, or written complaints strengthens the application. The landlord may dispute the request, and the LTB may schedule a hearing. Filing on time and keeping good records is essential.
T5 – Tenant Application About Maintenance
The T5 form is used when a landlord fails to maintain the rental unit. This includes serious issues like no heat or water, as well as ongoing repair problems. Tenants should document the issue with dates, photos, and repair requests.
After submission, the landlord can respond and the LTB may hold a hearing. Filing the T5 promptly can help resolve maintenance problems faster and protect tenant rights.
A1 – Application About Whether the Act Applies
The A1 form is used to confirm whether the Residential Tenancies Act applies to a living situation. This is common in shared housing or unique rental arrangements. Both landlords and tenants can use this form to get clarity.
Providing detailed information helps the LTB make an accurate decision. Filing early avoids uncertainty and potential legal mistakes. Keeping records of all communication is recommended.
Other Important LTB Forms and Agreements

There are many additional LTB forms that apply to specific situations, such as repayment agreements or consent forms. Knowing which forms exist helps prevent errors and delays.
Forms and rules can change, so it is important to use the most current versions from the LTB website. Missing deadlines or using the wrong form can cause complications. Professional guidance can help in complex cases.
N9 – Tenant’s Notice to End the Tenancy
The N9 form allows tenants to formally end a tenancy. The required notice period depends on the type of lease, so accuracy is important. Tenants must complete the form correctly and deliver it properly to the landlord.
Keeping proof of delivery protects the tenant if disputes arise. Submitting the N9 on time helps avoid extra rent obligations and protects rental history.
N10 – Agreement to Increase the Rent Above the Guideline
The N10 form is used when a landlord and tenant agree to a rent increase above Ontario’s annual guideline. The agreement must be voluntary and in writing.
The form must state the new rent, the start date, and the reason for the increase. Proper notice, usually 90 days, is required. Both parties should keep a signed copy for their records.
N11 – Agreement to End the Tenancy
The N11 form is used when both the landlord and tenant agree to end the tenancy. It clearly sets the move-out date and must be signed by both parties.
While reasons are optional, outlining final responsibilities can prevent misunderstandings. Keeping a copy of the signed agreement protects everyone involved.
