Mental Health & Tenancy Ontario 3 min read · published March 09, 2026 Flag of Ontario

If you are a tenant in Ontario planning to take a mental-health leave and need temporary help covering your rent, subletting can be an option. This guide explains what subletting means for renters, how to get landlord consent, what to include in a written sublet agreement, and steps to protect your tenancy and finances while you are away. It focuses on practical steps tenants can take to avoid disputes, document arrangements, and find a qualified temporary occupant, including how to involve official resources and when to escalate a refusal to the Landlord and Tenant Board. The tone is supportive and aimed at tenants who want clear, usable steps during a stressful period.

What the law says in Ontario

Under Ontario law tenants generally need the landlords permission to assign or sublet a rental unit. The Residential Tenancies Act, 2006 sets out tenants and landlords rights and includes rules about consent and disputes related to assignments and sublets[1]. If a landlord refuses consent you can apply to the Landlord and Tenant Board to resolve the dispute; the Board handles residential tenancy disputes in Ontario[2].

When subletting is allowed

Subletting is usually allowed if the lease does not explicitly ban it and the tenant follows the RTA process. Landlords cannot arbitrarily refuse a reasonable request to sublet, but they may consider the proposed subtenants suitability. Always check your lease for any clauses about assignments, sublets, or notice requirements before you proceed.

Practical steps to sublet while on mental-health leave

  1. Get written consent from your landlord as soon as you can and keep that consent with your tenancy records.
  2. Use a written sublet agreement that states the rent amount, who pays utilities, the sublet term, and responsibilities of the subtenant.
  3. Screen applicants and collect references, ID, and contact details to document who will be occupying your unit.
  4. Decide who will collect and remit rent during your leave and keep clear receipts or electronic payment records.
  5. Complete a move-in condition report and take dated photos to protect against damage claims when you return.
  6. Set a clear end date for the sublet and provide notice to your landlord as required under your lease or by agreement.
Keep all written agreements, receipts, and dated photos together in one folder for quick access.

Dealing with a landlord who refuses

If your landlord refuses a reasonable request to sublet, try negotiating in writing first: explain your leave, share the proposed sublet agreement, and offer references for the subtenant. If negotiation fails, you can consider filing an application with the Landlord and Tenant Board to challenge an unreasonable refusal. For practical guidance on raising formal complaints or preparing evidence see How to Handle Complaints in Your Rental: A Tenant's Guide and review the Boards application instructions and forms[3].
