Mediation or Adjudication at Ontario's LTB: Which Is Right?

Dispute Resolution & LTB Ontario 5 min read · published March 09, 2026 Flag of Ontario

Facing a dispute with your landlord—whether it's over rent increases, repairs, or potential eviction—can feel overwhelming. In Ontario, the Landlord and Tenant Board (LTB) offers two main options to resolve tenancy disputes: mediation and adjudication. Knowing how each process works empowers you to choose the best path forward under the Residential Tenancies Act, 2006.[1]

Gather key documents now: your lease, rent receipts, any notices, and a concise summary of the issue. Bring these to mediation or to your LTB hearing.

Understanding the LTB: Ontario's Rental Tribunal

The Landlord and Tenant Board (LTB) handles disputes between tenants and landlords in Ontario. It provides processes designed to be accessible and fair for both sides, even without legal representation.

You can access free information and, in some cases, brief legal advice from community legal clinics or CLEO resources; check local clinics for eligibility.

Mediation and Adjudication Defined

When you have a tenancy problem, such as a disagreement about unpaid rent, repairs, or a notice to vacate, your case may go through either mediation or adjudication at the LTB. Here’s what each process involves:

What Is Mediation?

Mediation is a voluntary process where you and your landlord meet with an LTB mediator to try to reach a mutually agreeable solution. It's informal, confidential, and focuses on collaborative problem-solving.

  • You control the outcome—nothing is decided unless both sides agree.
  • It's faster and less formal than a traditional LTB hearing.
  • Agreements can be written and enforced by the LTB if needed.
Many tenants find that mediation helps resolve disputes without stress. It's especially helpful if you want to maintain a positive rental relationship.

Common issues resolved by mediation include repayment plans for overdue rent, arrangements for repairs, or decisions about moving-out dates. How to Handle Complaints in Your Rental: A Tenant’s Guide provides more information on resolving disputes early.

What Is Adjudication?

Adjudication is a formal process where an LTB Member (similar to a judge) listens to both sides and makes a binding decision. This process is often used when mediation fails or parties prefer a formal resolution.

  • The LTB Member applies Ontario rental law to decide the outcome.
  • You have less control over the result—it is legally binding.
  • The outcome is based on evidence, arguments, and legislation.

Adjudication typically occurs in more complex cases, or if previous attempts to settle the issue (such as through mediation) were unsuccessful.

Mediation vs Adjudication: How to Choose?

The best choice depends on your situation and goals. Here’s a summary to help you decide:

  • Mediation: Ideal if you want a quick, cost-effective, and collaborative outcome where you and your landlord can talk things through.
  • Adjudication: Necessary if you need a legal ruling, the relationship has broken down, or you require an official decision to enforce your rights.

Consider mediation first, especially for less severe issues or if both parties are open to compromise. If not, adjudication assures a final, enforceable result.

The best choice depends on your situation and goals. Here’s a summary to help you decide:

Tip: Mediation is usually faster and cheaper, but adjudication provides a formal ruling if you need enforceable rights. Review which issues fit each path before filing.

Key LTB Forms for Tenants

You may need to use one or more official LTB forms to start or respond to a dispute process. Here are some of the most common forms used by Ontario tenants at the LTB:

  • Form T2: Application About Tenant Rights (download from the LTB)
    Use this form to ask the LTB to address issues such as maintenance, harassment, or illegal landlord actions.
    For example, if your landlord refuses to do essential repairs, you can file a T2 application with supporting evidence.
  • Form T6: Tenant Application About Maintenance (download from the LTB)
    Use when trying to get the LTB to order your landlord to complete necessary repairs or compensate you for losses due to poor maintenance.
    For instance, if your unit has pests or mould and the landlord won't fix it, submit a T6 with proof.
  • Form N12 or N4 (Notices to End Tenancy) (all LTB forms)
    Tenants may receive these forms from landlords if there's an allegation of non-payment or for landlord's own use. It's important to respond on time.

All forms should be submitted according to instructions on the official LTB forms page. If you disagree with a notice, you can attend the scheduled hearing and request mediation or adjudication.

Action Steps: Starting Dispute Resolution at the LTB

Here are the general steps for tenants facing a dispute:

  • Receive a notice or recognize a problem (e.g., repair issue, notice to end tenancy).
  • File the correct LTB form (such as T2 or T6) if initiating a complaint, or prepare your response if a hearing is scheduled.
  • Attend your LTB hearing (usually virtual or in-person)—you’ll often be offered the option to try mediation before adjudication begins.
  • If both parties agree in mediation, sign a settlement. If not, proceed to a formal hearing for adjudication.

FAQ: Tenants and LTB Dispute Resolution

  1. What is the main difference between mediation and adjudication at the LTB?
    Mediation is a voluntary process where parties try to reach an agreement with the help of an LTB mediator. Adjudication is a judicial process where an LTB Member makes a legally binding decision.
  2. Can I refuse mediation and go directly to a hearing?
    Yes. Mediation is voluntary. You can choose to go straight to a hearing for adjudication if you prefer or if mediation isn’t successful.
  3. Do I need a lawyer or paralegal for LTB mediation or adjudication?
    No, you do not need legal representation, but you can choose to have one. Both processes are designed to be accessible to the public.
  4. What happens if an agreement is reached during mediation?
    The agreement is written down and becomes legally binding. If either party breaks the agreement, the LTB can enforce it.
  5. Where do I find official LTB forms?
    All current forms are available on the LTB official forms page.

Conclusion: Key Takeaways

  • Mediation offers a collaborative and quicker way to resolve disputes.
  • Adjudication is necessary for formal, enforceable decisions if mediation fails or isn’t appropriate.

Summary: Whether you choose mediation or adjudication, the LTB process in Ontario aims to help tenants and landlords resolve disputes fairly and efficiently.
