9 Proven Ontario Standard Lease Additional Terms (And the Costly Mistakes to Avoid)

Ontario Standard Lease Additional Terms: Why Section 15 Matters for Every Tenancy

Are you confident that your lease covers every detail—without stepping over legal boundaries? For nearly every residential tenancy in Ontario, understanding how ontario standard lease additional terms work is essential for both landlords and tenants. Section 15 of the mandated Ontario standard lease is a powerful tool, letting both sides add specific rules to their agreement. But there’s a catch: these extra terms must comply with the Residential Tenancies Act (RTA) and cannot override legal rights or obligations.

Section 15 is the only part of the lease where you can add unique arrangements—think rules about shared amenities, parking expectations, or move-in logistics—that aren’t already outlined in the standard form. According to the official government guide, these terms must be firmly attached to the lease if used, clearly marked as part of the agreement, and written in plain language understood by both sides. For downloadable forms and official instructions, visit the Ontario standard lease forms portal.

But what makes a term “additional” within the meaning of section 15? To be valid, it must address elements that are unique to your tenancy—such as special storage rights, approved paint colors, or the use of backyard amenities. It should never seek to remove or limit tenant rights or landlord responsibilities established by Ontario law. If you’re dealing with investment property rentals or specialized agreements like student rental agreements, section 15 is where the critical details live.

When used right, ontario standard lease additional terms bring instant clarity, reducing the chance of costly misunderstandings or legal disputes down the road. For both landlords and tenants, knowing how to make section 15 work in your favor is the first step toward a peaceful and law-abiding rental relationship.

What You Can (and Can’t) Include in Ontario Standard Lease Additional Terms

Thinking of adding those “little extras” to your rental agreement? Before you personalize, remember: Ontario standard lease additional terms can only enhance, not restrict, tenant or landlord rights granted by the Residential Tenancies Act. Section 15 allows you to handle specific situations—like rules about laundry, use of parking spots, procedures for keys, or responsibilities for snow clearing. For more examples and a detailed breakdown, the official Ontario standard lease guide is an excellent reference.

Permissible Ontario standard lease additional terms must be tailored to the unique features of your property or tenancy. Common examples include:

• Designated move-in/out times
• Protocols for use of shared amenities (like pools or gyms)
• Utility setup steps and deadlines
• Expectations for key hand-off and return
• Rules around minor cosmetic modifications (such as painting with pre-approved colors)
• Instructions regarding the use and care of major appliances

However, there are strict limits. Any clause that would remove a right or responsibility protected under the RTA is automatically void. Unlawful examples include:

• Banning pets outright (unless required by condo by-laws and not simply by landlord choice)
• Forbidding guests, additional occupants, or roommates
• Charging illegal deposits, fees, or penalties (beyond what the RTA allows)
• Assigning repair costs for landlord responsibilities to the tenant

One of the most common myths is that any “reasonable” clause is enforceable. In reality, even a well-intentioned rule about visitor limits, pet bans, or forced renter’s insurance can still conflict with the law on landlord rights and be ruled invalid. Legal outcomes depend on strict adherence to the RTA and current best practices, which you can monitor through trusted resources like this CLEO legal guide and the SingleKey Ontario lease overview.

The bottom line? Before you add, double-check compliance—especially if you’re managing multiple properties or navigating hidden legal risks in landlord-tenant relations.

Don’t hesitate to ask questions or challenge unlawful terms before signing—doing so can save hundreds in disputes later on.

Making Ontario Standard Lease Additional Terms Suit Your Needs
