Non-Standard Lease Forms in Ontario: Tenant Risks

Leases & Agreements Ontario 4 min read · published June 24, 2026 Flag of Ontario

If you're renting in Ontario, signing a non-standard lease form can introduce unexpected rules that change your rights and responsibilities. Tenants often accept clauses that conflict with the Residential Tenancies Act or ask for extra fees, waivers, or personal obligations not permitted by law. This guide explains common red flags in non-standard leases, practical steps tenants can take to protect deposits and safety, and how to use official forms and the Landlord and Tenant Board if a dispute arises. It focuses on clear, tenant-friendly advice and shows when to seek help so renters can make informed decisions and avoid costly mistakes.

What non-standard lease forms mean in Ontario

Non-standard lease forms are any rental agreements that add terms beyond Ontario's standard rules under the Residential Tenancies Act[2]. These clauses can try to shift legal responsibilities, require payments the Act does not allow, or ask tenants to waive rights. Because the Act sets minimum rules, any clause directly contradicting it is likely unenforceable, but that does not stop landlords from asking tenants to sign such forms.

Avoid signing clauses that require you to waive legal rights.

Common red flags to watch for

  • Clauses requiring extra non-refundable fees or large up-front payments beyond standard deposits.
  • Terms that ask you to waive rights under the Residential Tenancies Act or to accept illegal penalties.
  • Language allowing unrestricted landlord entry without proper notice or a specified reason.
  • Requirements that shift normal repair and maintenance obligations onto tenants for issues that affect habitability.
  • Demands for unusually large deposits described as "security" but marked non-refundable.
Document concerns with photos and dated notes before you sign.

What tenants should do before signing

Before you sign any lease, read every clause carefully and compare it to your basic rights. Ask the landlord to put any agreed changes in writing and keep a signed copy. If a clause refers to a deposit, cleaning fee, or damage charge, check what is lawful and reasonable and consult official guidance or legal help if unsure. For practical details about deposits and how they must be handled, see Understanding Rental Deposits: What Tenants Need to Know.

Always get a dated, signed copy of the final agreement before handing over money.

After signing: what to do next

Once the lease is signed, record the unit condition with photos and a written checklist and follow the guidance about next steps and tenant responsibilities in What Tenants Need to Know After Signing the Rental Agreement. Keep receipts for rent and any agreed payments, and keep copies of all communications in case you need to prove the landlord agreed to changes.

Official forms you may need and when to use them

The Landlord and Tenant Board provides formal application forms for disputes and enforcement. Common examples include:

  • L1 (Application to evict for non-payment of rent) — used by a landlord to recover arrears; a tenant may respond if asked to sign a lease that tries to require extra rent payments beyond the lawful amount.
  • L2 (Application related to damage, illegal activity or serious breaches) — used when alleged behaviour or damage is in dispute; tenants can use the Board to challenge unfair clauses that impose unreasonable responsibilities.
  • N11 (Agreement to End a Tenancy) — if both parties agree, this form documents a mutual, voluntary move-out date.

These forms and the Board's filing instructions are available from the Landlord and Tenant Board website[1]; they include user guides and information about online filing, timelines, and fees. For example, if a landlord tries to keep a non-refundable "cleaning" deposit that duplicates normal wear, you could file an application asking the Board to decide.

You can file many Board applications online or by mail through the Landlord and Tenant Board portal.

How the Landlord and Tenant Board and the law protect you

The Landlord and Tenant Board adjudicates disputes under the Residential Tenancies Act[2] and can issue orders requiring refunds, repairs, or that a landlord stop enforcing an illegal clause. Knowing the Act's basics helps you spot unenforceable terms. For a concise summary of tenant rights specific to Ontario, see Tenant Rights and Landlord Rights in Ontario.

FAQ

Are non-standard lease clauses enforceable in Ontario?
Some are enforceable if they do not conflict with the Residential Tenancies Act; any clause that tries to remove your statutory protections is likely unenforceable and can be challenged at the Board.
What should I do if a landlord asks me to sign a non-standard lease?
Ask for time to review, request written changes, document the discussion, and consult official resources or legal aid before paying money or moving in.
How do I challenge a clause after I have already signed?
Gather evidence, save communications, and consider filing an application with the Landlord and Tenant Board to dispute the clause; bring photos, receipts, and copies of the agreement to your hearing.

How-To

  1. Read the entire lease carefully and highlight any unfamiliar or one-sided clauses.
  2. Contact the Landlord and Tenant Board or local tenant advice services to ask whether a clause is lawful.
  3. Collect evidence such as photos, receipts, dated messages, and witness names to support your case.
  4. File the appropriate application form with the Board and pay any required fee, following the Board's filing instructions[1].
