How to File a Tenant Complaint in Ontario

Tenant Rights & Responsibilities Ontario 4 min read · published March 09, 2026 Flag of Ontario

Living in a rental home in Ontario comes with certain rights and responsibilities for both tenants and landlords. If you're experiencing issues such as unresolved repairs, unsafe conditions, unwarranted rent increases, or difficulties communicating with your landlord, it's important to know how to file a formal complaint and protect your rights as a tenant. This guide explains the steps, forms, and resources available to Ontario tenants when problems arise.

Understanding Tenant Complaints in Ontario

Tenant complaints can range from maintenance issues and health hazards to unlawful eviction or rent increases. Common reasons tenants file complaints include:

  • Lack of essential repairs (e.g., plumbing, heating, electricity)
  • Health and safety code violations
  • Unreasonable rent increases
  • Unauthorized entry by landlord
  • Disputes over security deposits or lease agreements

Ontario tenants are protected under the Residential Tenancies Act, 2006, which sets out the rights and duties for both tenants and landlords.

Start by Communicating Directly

If you face an issue, try resolving it directly with your landlord first. Put your request in writing and clearly outline the problem and your expectations for resolution. Keeping records of all correspondence is essential.

Email or text your landlord about the issue first, then follow up with a dated letter if needed. This creates a clear paper trail that will strengthen your case if you need to escalate.

Filing a Complaint: Step-by-Step Guide

Depending on your concern, you may contact your municipality (for building or health code issues) or the official tribunal responsible for rental disputes: the Landlord and Tenant Board (LTB) of Ontario.

Step 1: Identify the Complaint Type

  • Is your complaint about essential repairs, safety, or standards? Contact your municipality’s bylaw or public health office first.
  • For issues around evictions, rent, or landlord behavior, file directly with the LTB.

Step 2: Gather Documentation

  • Written communication between you and your landlord
  • Photos or evidence of the issue
  • Relevant receipts, notices, or agreements
Take date-stamped photos of maintenance issues weekly until resolved. This creates visual proof of how long problems persist and their severity.

Step 3: Submit the Appropriate Form to the Landlord and Tenant Board

  • T2: Application about Tenant Rights – Use this form if your landlord has interfered with your rights (e.g., entered without notice, withheld services, harassed you).

  • T6: Tenant Application about Maintenance – Use this if your landlord is failing to maintain your unit according to health, safety, or municipal standards.

Submit your LTB application within one year of the issue starting. Missing this deadline could prevent you from getting help for maintenance-related complaints.

Step 4: Pay the Filing Fee

Most LTB applications require a fee (as of 2024, generally $53 for tenants, but check the current LTB fee schedule). Fee waiver requests are available for tenants with financial hardship.

Step 5: Attend the Hearing

After filing your complaint, you’ll receive a notice of hearing. At the hearing:

  • Present your evidence and documentation
  • Explain your situation to the LTB Member (decision maker)
  • The Board will make a legally binding order or ruling

Tips for Filing Effective Complaints

  • Be clear and specific about the problem
  • Keep a detailed timeline of events
  • Maintain copies of all forms, emails, and letters
  • If you need advice, consider seeking support from tenant advocacy organizations

Your Rights: Key Points for Ontario Tenants

Tenants in Ontario are protected by robust regulations, and you cannot be evicted, harassed, or penalized for filing a legitimate complaint. If you feel your rights are being violated, knowing your options and acting quickly is essential.

Landlords must give 24 hours written notice before entering your unit, except in emergencies. Keep a log of any unauthorized entries with dates/times as evidence if needed.
