How to Request Accessible Unit Modifications in Ontario

Discrimination & Accessibility Ontario 4 min read · published March 09, 2026 Flag of Ontario

Tenants with disabilities in Ontario may need changes to their rental unit to make daily life safer and more independent. This guide explains how tenants can ask a landlord for accessible unit modifications, what documentation to prepare, reasonable timelines to expect, and when to seek formal help from the Landlord and Tenant Board or the Human Rights Tribunal of Ontario. It uses plain language and practical examples aimed at renters and tenants, including when to include medical or support letters, how to propose cost-sharing or restoration agreements, and how to track communications to strengthen your case. Read on for step-by-step actions and links to official forms and resources for Ontario tenants.

Understanding your rights in Ontario

Under the Residential Tenancies Act, 2006 tenants have protections about habitability and certain obligations around alterations; use the Act for legal details and limits.[1] If you and your landlord cannot agree, the Landlord and Tenant Board handles tenancy disputes in Ontario and can explain processes for unresolved modification requests.[2] Where a denial may raise discrimination or accommodation issues, the Human Rights Tribunal of Ontario considers claims about disability discrimination and accommodation obligations.[3]

For practical context on duties and expectations, review obligations for both sides and tenant-specific facts such as provincial protections and common landlord responses. See Obligations of Landlords and Tenants: Rights and Responsibilities Explained to compare common responsibilities, and consult Tenant Rights and Landlord Rights in Ontario for a province-focused overview.

How to prepare a clear written request

Start with a polite, dated, written request so there is a record. State the change you need, why it is necessary for accessibility, and any suggested timelines or installers you recommend. Offer to discuss reasonable cost arrangements and whether you will restore the unit at the end of tenancy.

  • A clear written request describing the modification needed, the reason, and the date you delivered the request.
  • Supporting documents such as a letter from a health professional, an occupational therapist assessment, or photos showing current barriers.
  • A proposed timeline for the work and your availability for access, with a suggestion to agree on reasonable scheduling.
  • A short proposal about costs and restoration, for example: "I can pay up to $X now and will restore the unit on move-out if you prefer."
Keep a dated copy of every message you send and receive about the modification.

If the landlord refuses or delays

Try to resolve by phone or meeting, then follow up in writing summarizing what was discussed and any offers. If the landlord refuses without discussing reasonable alternatives, you can consider formal options: mediation, filing a tenancy application at the Landlord and Tenant Board for related tenancy issues, or pursuing an accommodation claim at the Human Rights Tribunal.

  • Contact local tenant supports or community legal clinics for help drafting your request and understanding options.
  • File an application or request information from the Landlord and Tenant Board when the dispute relates to tenancy matters.
  • Consider the Human Rights Tribunal of Ontario for claims about discrimination or refusal to accommodate.
Respond to any landlord communication promptly and keep all records to protect your rights.

FAQ

Do I need a doctors note to ask for a modification?
No. You can request a modification in writing without a medical note, but supporting documentation like a doctors or therapists letter can strengthen your case and clarify the need.
Can a landlord charge me for accessibility changes?
Landlords may ask for reasonable cost agreements or require restoration at move-out; its best to propose clear terms in writing and keep copies of any agreements.
What if the landlord allows the change but wants independent contractors?
Agree on licensed, insured installers and confirm timelines in writing; keep receipts and photos in case of future disputes.

How-To

  1. Write a dated, clear request describing the exact modification, why its needed, and attach any supporting documents.
  2. Give the landlord reasonable time to respond and suggest dates for inspection or work to begin.
  3. If denied, collect evidence of communications, estimates, and expert letters to support your position.
  4. If informal resolution fails, file with the appropriate body (LTB for tenancy issues or HRTO for accommodation complaints) and include your records.

Key Takeaways

  • Always make modification requests in writing and keep dated copies.
  • Supporting documentation strengthens accommodation requests.
  • Seek help early from tenant clinics or official tribunals if you cannot reach an agreement.
