Ontario Required Landlord Disclosures: What You Must Tell Tenants

Ontario landlords have several mandatory disclosure obligations under the Residential Tenancies Act, 2006 (effective 31 January 2007) and related regulations. Failing to meet these requirements can give tenants the right to withhold rent or file applications with the Landlord and Tenant Board (LTB).

Summary of Required Disclosures

Ontario Standard Form of Lease

Since April 30, 2018, most private residential landlords must use the Ontario Standard Form of Lease for all new tenancy agreements. This applies to:

• Apartments and houses
• Condominiums rented by the owner
• Single rooms in a house (in most cases)
• Secondary suites and basement apartments

What the Standard Lease Includes

The government-prescribed form covers:

• Names of the landlord and tenant
• Address of the rental unit
• Term of the tenancy (start date, fixed-term or month-to-month)
• Rent amount and payment due date
• Services and utilities included in rent
• Rent deposit information
• Rules about smoking and insurance
• Additional terms (which must comply with the RTA)

If the Landlord Does Not Provide the Standard Lease

If a tenant requests the standard lease in writing and the landlord fails to provide it within 21 days, the tenant may:

1. Withhold the lesser of one month's rent or $10,000 as a remedy (RTA s. 12.1(6))
2. If the landlord still does not provide it within the next 30 days, the tenant can keep the withheld rent (the landlord is not entitled to the withheld rent per RTA s. 12.1(9))
3. The tenant's obligation to pay future rent is only suspended until the lease is provided, but the specific withheld amount is permanently forfeited if the 30-day deadline is missed.

Landlord Identity Disclosure

This information must be provided within 21 days of the start of the tenancy. Failure to do so may affect the enforceability of notices served on the tenant.

Information for New Tenants Brochure

Under Section 11 of the RTA, every landlord must provide a new tenant with a document containing information about the rights and responsibilities of landlords and tenants, the role of the Landlord and Tenant Board (LTB), and how to contact the Board.

• Required Form: "Information for New Tenants" brochure (prescribed by the LTB).
• Deadline: On or before the day the tenancy begins.
• Consequence: Failure to provide this brochure may be considered by the LTB in applications regarding maintenance or harassment.

Rent Increase Disclosures

Before increasing rent, landlords must:

1. Provide at least 90 days' written notice using Form N1 (for rent-controlled units) or Form N2 (for units exempt from rent control)
2. The notice must specify the new rent amount and the effective date
3. Informal communications (emails, text messages, verbal conversations) are not legally valid rent increase notices

Suite Metering Disclosure

If the rental property uses utility sub-metering (where tenants pay for their own electricity usage separately from rent), landlords must:

• Disclose the sub-metering arrangement before the tenancy begins
• Ensure the sub-metering provider is licensed under the Ontario Energy Board Act, 1998 (RTA s. 137(2))
• Provide clear information about how utility charges are calculated

Lead Paint and Environmental Disclosures

Unlike some other jurisdictions, Ontario does not have a specific lead paint disclosure statute for residential rentals. However:

• Properties must comply with general health and safety standards
• If the landlord is aware of hazardous materials (asbestos, mold, lead paint), they have a general duty under common law and the Occupational Health and Safety Act to ensure the premises are safe
• Municipal property standards bylaws may require specific hazard disclosures

Disclosure of Prior Eviction Notices

When applying to the LTB for a no-fault eviction (N12 for landlord's own use, N13 for demolition/renovation), landlords must disclose:

• All notices of termination given under s. 48 or s. 50 in the previous two years for any rental unit (regardless of whether an application was filed)
• Whether previous evictions were carried out in good faith
• This helps the LTB assess whether the current application is genuine (RTA s. 71.1)

Best Practices for Ontario Landlords

1. Always use the Ontario Standard Lease — Even if not strictly required, it protects both parties
2. Keep copies of all documents — Maintain signed copies of leases, notices, and disclosures
3. Provide lease copies promptly — Within 21 days to avoid rent withholding
4. Use proper forms for notices — LTB forms are mandatory; informal notices are not valid
5. Document everything in writing — Verbal agreements are enforceable but harder to prove
6. Stay updated on regulatory changes — Ontario periodically updates disclosure requirements
