    Creating a Lease Agreement: Key Clauses to Include

    A well-drafted lease agreement is your most important tool as a landlord. While Ontario requires using the Standard Lease, you can add additional legal terms and conditions. Here are the key elements to include.

    Standard Required Information

    The Ontario Standard Lease covers the basics: tenant and landlord names, property address, rent amount and due date, lease term, and what's included (utilities, parking, etc.). Ensure all this information is accurate and complete.

    Additional Terms to Consider

    Guest and Occupancy Policies

    Specify who is authorized to live in the unit and establish reasonable guest policies. This helps prevent unauthorized occupants or subletting.

    Maintenance Responsibilities

    Clarify who is responsible for what. While major systems are always the landlord's responsibility, specify tenant duties like lawn care, snow removal, or changing furnace filters.

    Pet Policies

    Note that Ontario law limits a landlord's ability to prohibit pets. However, you can include clauses about tenant responsibility for any pet-related damage.

    Insurance Requirements

    Require tenants to maintain renter's insurance. This protects their belongings and provides liability coverage that can benefit both parties.

    Notice Requirements

    Specify how formal notices should be delivered and what constitutes proper notice. Include current contact information for all parties.

    Smoking and Cannabis

    You can prohibit smoking of any substances in the rental unit. Be specific about what is and isn't allowed.

    What You Cannot Include

    Some clauses are automatically void under Ontario law:

    • Requiring a key deposit or damage deposit
    • Prohibiting pets (though you can address damage)
    • Requiring post-dated cheques
    • Limiting guests unreasonably
    • Waiving rights under the Residential Tenancies Act

    Have your lease reviewed by a legal professional or experienced property manager to ensure it's both comprehensive and enforceable.
