How to Create a Strong, Legal Lease Agreement in Ontario’s Rental Market

Introduction

A lease agreement is more than just a piece of paper — it’s the foundation of the landlord-tenant relationship. In Ottawa’s active and competitive rental market, having a clear, legally compliant lease is essential to protecting your property, ensuring consistent rental income, and avoiding unnecessary disputes.

The Legal Requirement in Ontario
In Ontario, most residential landlords are legally required to use the provincial Standard Lease Agreement. This standardized form was introduced to simplify rental terms, improve transparency, and reduce misunderstandings between landlords and tenants. While the core structure is fixed, landlords can add additional clauses — provided they don’t conflict with the Residential Tenancies Act (RTA). These custom clauses can be critical for protecting your specific property and clarifying expectations.

Why Details Matter
The basic Standard Lease Agreement covers essential information such as rent amount, payment schedule, and included services. However, the finer details — like maintenance responsibilities, rules for subletting, pet policies, or parking arrangements — can make the difference between a smooth tenancy and a costly dispute. A vague or incomplete lease can leave room for misunderstandings, while a precise one sets clear boundaries and expectations from the start.

Key Clauses Landlords Should Consider
While the RTA sets many default rules, certain terms can and should be spelled out clearly in the lease:

  • Maintenance and Repairs: Outline tenant and landlord responsibilities for upkeep.

  • Smoking and Pets: State your property’s policy clearly to avoid conflicts later.

  • Utilities: Clarify which utilities are included in rent and how others will be billed.

  • Guest Policies: Prevent unauthorized long-term guests that could lead to wear and tear.

  • Move-Out Conditions: Specify cleaning expectations and key return procedures.

Compliance and Clarity
It’s important to remember that any clause conflicting with the RTA is unenforceable. For example, you can’t include a “no overnight guests” clause if it violates tenant rights, and you can’t require a security deposit beyond the legal rent deposit limit. Ensuring that every term is both legal and practical is critical for enforceability.

The Bottom Line
In Ottawa’s competitive rental market, a well-crafted lease agreement is one of the most valuable tools a landlord has. It sets the tone for the tenancy, protects both parties’ rights, and minimizes the risk of disputes. By combining the standardized provincial form with clear, property-specific clauses — and by working with experienced professionals — landlords can enjoy smoother tenancies and stronger legal protection.

1. Why a Strong Lease Matters

A well-crafted lease agreement:

  • Sets clear expectations for both parties.

  • Protects the landlord’s rights.

  • Reduces misunderstandings.

  • Serves as evidence in case of disputes.

Without a detailed lease, landlords risk legal challenges and income loss.

2. The Ontario Standard Lease Requirement

Since April 30, 2018, the Government of Ontario has required landlords to use the Standard Lease form for most residential rental agreements. This form includes:

  • Names of the landlord and tenant(s).

  • The rental unit’s address.

  • Start and end date of the tenancy.

  • Rent amount, due date, and payment method.

  • Services included in the rent (utilities, parking, etc.).

  • Rules for maintenance and repairs.

Landlords may attach additional clauses as long as they do not conflict with the Residential Tenancies Act (RTA).

3. Key Clauses to Include

While the Standard Lease covers the basics, adding specific clauses can protect your property further:

  • Late payment policy – Specify when rent is considered late and the process for handling it.

  • Property maintenance – Outline tenant responsibilities for cleanliness and reporting repairs.

  • Pet policy – While “no pets” clauses are generally unenforceable in Ontario, you can still set rules about pet damage or noise.

  • Smoking policy – Indicate whether smoking or vaping is allowed and where.

  • Insurance requirement – Require tenants to maintain renter’s insurance.

4. Rent Payment Terms

A strong lease should detail:

  • The exact rent amount.

  • Due date (usually the first of the month).

  • Accepted payment methods (e-transfer, cheque, online portal).

  • What happens if rent is late (in line with Ontario law).

5. Maintenance and Repairs

Tenants are responsible for keeping the unit clean and reporting issues promptly. Landlords are responsible for maintaining the property in good repair and meeting health and safety standards. Your lease should clearly define each party’s duties to avoid disputes.

6. Entry to the Unit

Under Ontario law, landlords must give 24 hours’ written notice before entering a tenant’s unit (except in emergencies). Your lease should outline:

  • Valid reasons for entry (repairs, inspections, showings).

  • How notice will be given (email, printed letter).

7. Lease Renewals and Terminations

The Standard Lease automatically renews as a month-to-month tenancy if neither party gives notice at the end of the term. The lease should include:

  • Notice requirements for ending the tenancy.

  • Rules for renewals.

  • Procedures for increasing rent in compliance with Ontario’s guidelines.

8. Security Deposits and Last Month’s Rent

Ontario does not allow traditional “security deposits” for damages. However, landlords can collect last month’s rent in advance. This must be applied to the final month of tenancy and accrues interest annually at the guideline rate.

9. Avoiding Illegal Clauses

Any lease clause that contradicts the Residential Tenancies Act is unenforceable. Examples include:

  • Charging more than one month’s rent as a deposit.

  • Waiving the tenant’s right to maintenance.

  • Banning guests entirely.
