Why are so many Ontario landlords losing cases at the Landlord and Tenant Board? Because they’re still using illegal lease agreements from 2017.
If you’re a landlord in Ontario and you’re not using the Ontario Standard Lease Agreement (Form 2229E), your lease is legally unenforceable. That means if a tenant stops paying rent, damages your property, or violates the lease, the Landlord and Tenant Board (LTB) can dismiss your application outright — even if you’re 100% in the right.
This isn’t a recommendation. It’s Ontario law. Since April 30, 2018, the Residential Tenancies Act (RTA) has mandated that all new residential tenancies use the standardized provincial lease form. Yet thousands of Ontario landlords — many in Niagara Falls, St. Catharines, Welland, and across the region — continue to operate with outdated, non-compliant agreements they downloaded from Google or inherited from previous owners.
This guide explains exactly what the Ontario Standard Lease is, what clauses are mandatory, which clauses are illegal, and how to avoid the costly mistakes that land landlords in legal trouble. Whether you’re renting out a basement apartment, a condo, or a multi-unit building, this is required reading.
What Is the Ontario Standard Lease Agreement?
The Ontario Standard Lease Agreement (officially titled Form 2229E) is a legally mandated document created by the Ontario government to standardize residential rental agreements across the province. It applies to most private residential rental units, including:
- Single-family homes, townhouses, and condos
- Basement apartments and secondary suites
- Multi-unit rental buildings (apartments)
Who is exempt from using the Standard Lease?
- Social housing or rent-geared-to-income units
- Commercial or mixed-use properties
- Long-term care homes or retirement homes
- Co-op housing
- Mobile home sites or land lease communities
📋 CRITICAL: If your rental property is a standard residential unit, you MUST use the Standard Lease. There are no exceptions.
Why Was the Standard Lease Created?
Prior to 2018, Ontario landlords used a chaotic mix of homemade templates, real estate board forms, and lawyer-drafted contracts. Many included illegal clauses that violated tenant rights. The Ontario government standardized the lease to:
- Protect tenants from predatory or illegal lease terms
- Clarify rights and obligations for both landlords and tenants
- Reduce disputes by ensuring everyone operates under the same legal framework
- Streamline LTB hearings by providing a universal reference document
The 7 Mandatory Components of the Standard Lease
The Ontario Standard Lease is a pre-formatted 13-page document. You cannot remove sections, but you can add legal, compliant addendums. Here are the 7 mandatory components:
Here is exactly what you need to have ready:
| Mandatory Section | What It Covers |
|---|---|
| 1. Parties & Property Details | Full names, rental address, unit number, parking, storage |
| 2. Term & Rent Amount | Start date, rent amount, payment method, due date, utilities included |
| 3. Services & Utilities | Who pays for hydro, gas, water, heat, internet, cable, garbage |
| 4. Rent Discounts | Disclosure of promotional discounts or incentives (e.g., first month free) |
| 5. Rent Deposit | Last month’s rent only — no other deposits allowed by law |
| 6. Smoking Rules | Cannabis, tobacco, and e-cigarette policies |
| 7. Tenant & Landlord Responsibilities | Maintenance, repairs, entry notice, insurance requirements |
What You CAN Add to the Standard Lease (Legal Addendums)
The Standard Lease allows landlords to attach Additional Terms as long as they comply with the Residential Tenancies Act. Legal addendums include:
- Condo-specific rules: Noise bylaws, pet restrictions per condo board rules, guest policies
- Maintenance schedules: HVAC filter changes, lawn care responsibilities, snow removal
- Key replacement fees: Actual cost only (e.g., $50 for electronic fob, not $300)
- Move-in condition report: Attached photos documenting pre-existing damage
- Insurance requirements: Proof of tenant liability insurance minimum coverage
✅ KEY RULE: Any additional clause must NOT contradict or weaken a tenant’s rights under the RTA. If it does, it’s void — even if the tenant signed it.
The 10 Illegal Clauses Landlords MUST NEVER Include
These clauses are automatically void under Ontario law, even if both parties agree and sign:
- No guests allowed — You cannot restrict guests or overnight visitors
- Mandatory professional cleaning — You cannot force tenants to hire cleaners upon move-out
- No subletting — Tenants have a legal right to request sublets (you can refuse with valid reason)
- Security deposits — Only last month’s rent is legal. No damage deposits, pet deposits, or key deposits beyond actual cost
- Automatic rent increases — Rent can only increase once per 12 months with 90 days written notice
- Waiving the right to LTB hearings — You cannot force arbitration or waive tenant’s right to file complaints
- Landlord entry anytime — Landlord must provide 24 hours written notice except emergencies
- No children allowed — This is a Charter rights violation and a Human Rights Code breach
- Move-out cleaning fees — You cannot charge cleaning fees deducted from deposits
- Holding deposits — You cannot take money to ‘hold’ a unit before signing the lease
⚠️ WARNING: If the LTB finds an illegal clause in your lease, your eviction application can be dismissed, and you may owe the tenant compensation.
What Happens If You Don't Use the Standard Lease?
Failure to provide the Standard Lease has serious consequences:
- Tenant can withhold one month’s rent — They notify you, and you have 21 days to provide the correct form
- Tenant can terminate the lease early — After 21 days, they can give 60 days notice to end the tenancy
- LTB may dismiss your applications — Your eviction or arrears claims may be thrown out on procedural grounds
- You lose negotiating power — Non-compliance weakens your legal standing in disputes
How to Properly Execute the Standard Lease (Step-by-Step)
- Download the official form from ontario.ca or obtain it from a licensed Realtor
- Fill in all mandatory fields — Do not leave blanks; write ‘N/A’ if a section doesn’t apply
- Attach legal addendums if needed (condo rules, move-in report, insurance requirements)
- Have all parties initial every page and sign the final signature page
- Provide the tenant a signed copy within 21 days of move-in
- Keep your signed copy in a secure file — you’ll need it for LTB hearings if disputes arise

FAQ — Ontario Standard Lease: Landlords' Top Questions Answered
Can I modify the Standard Lease wording?
No. The core sections are legally protected and cannot be altered. However, you can attach Additional Terms as an addendum, as long as they comply with the RTA.
What if my tenant signed a non-Standard Lease before 2018?
Leases signed before April 30, 2018 are grandfathered in and remain valid. However, if you renew or create a new lease, you must use the Standard Lease.
Can I charge a damage deposit in Ontario?
No. Ontario law allows only one deposit: last month’s rent. Damage deposits, pet deposits, and key deposits (beyond actual replacement cost) are illegal. You can sue for damages after move-out, but you cannot collect deposits upfront.
Do I have to pay interest on the last month's rent deposit?
Yes. Ontario landlords must pay interest annually on the deposit at the same rate as the provincial rent increase guideline (2.5% in 2025). You can apply this interest to the tenant’s final month’s rent.
Can I ban pets in my rental property?
Not in most cases. The RTA allows landlords to refuse pets only in condos where the condo corporation explicitly bans them. For other properties, you cannot refuse tenants with pets. However, you can evict if the pet causes damage, allergies, or safety issues.
What happens if my tenant refuses to sign the Standard Lease?
A tenancy can exist without a signed lease (it becomes month-to-month under RTA rules). However, you should always provide the Standard Lease within 21 days of occupancy. If the tenant refuses to sign, document this in writing.
Can I include a clause requiring tenant insurance?
Yes. Requiring tenant liability insurance is legal and recommended. Specify the minimum coverage (e.g., $2 million) in the Additional Terms section of the Standard Lease.
How do I evict a tenant for non-payment of rent?
You must file an N4 Notice (Notice to End a Tenancy Early for Non-payment of Rent) giving the tenant 14 days to pay. If they don’t pay, you file an L1 Application with the LTB. The Standard Lease does not change eviction procedures — it just ensures your lease is legally valid when you file.
Can I update my existing non-Standard Lease mid-tenancy?
No. You cannot force a tenant to sign a new lease mid-tenancy. However, when the lease expires and converts to month-to-month, or if you mutually agree to a renewal, you must use the Standard Lease.
Should I hire a lawyer or a Realtor to handle my lease?
