The Residential Tenancies Act vs. Your Lease: Which One Wins?
Both parties can sign a lease clause that conflicts with Ontario's tenancy law — and it generally won't matter. Here's why the Act almost always wins.

A floor, not a ceiling
It's a common and understandable assumption: if both a landlord and a tenant sign a lease, whatever it says is the deal. For most contracts, that's roughly true. For residential tenancies in Ontario, it isn't — and the reason is that the Residential Tenancies Act, 2006 (RTA) is designed to operate as a floor of minimum protections, not a ceiling on what a lease can address. A lease can add detail, cover situations the Act doesn't speak to, and set out the practical terms of a tenancy. What it generally cannot do is take away a right or protection the RTA gives a tenant, even where the lease language is clear and both parties agreed to it.
This idea — sometimes summarized as the Act being a floor a lease can build on but not dig beneath — is one of the more consequential and least understood features of Ontario tenancy law, and it's worth understanding in some depth, because it changes how a lease should actually be read.
Key point
A lease clause that conflicts with the RTA is generally void and unenforceable to the extent of the conflict, whether or not the tenant realized that when they signed it, and whether or not the landlord intended anything improper by including it.
Why both parties signing doesn't fix it
In ordinary contract law, two parties who freely agree to a term are generally bound by it. Tenancy law departs from that principle deliberately, because the legislature recognized that residential landlords and tenants often don't negotiate lease terms from equal footing — a prospective tenant facing a competitive rental market is rarely in a position to negotiate out a problematic clause, and may not even recognize a clause as problematic until a dispute arises. The RTA responds to that imbalance by making certain protections non-negotiable, regardless of what a signed document says.
This means a signature on a lease containing a void clause doesn't retroactively make that clause valid, and it generally doesn't stop a tenant from later relying on their RTA rights despite having signed something that appeared to give them up. It also means a landlord can't point to a tenant's agreement as a defence if a dispute over that clause ends up in front of the LTB.
Common clauses that generally don't hold up
A few examples come up repeatedly. A clause banning guests entirely, or requiring landlord approval for any overnight visitor, generally conflicts with a tenant's right to reasonable enjoyment of their unit and is not enforceable in that form. A clause purporting to let the landlord enter the unit at any time, or without the notice the RTA requires, generally cannot override the Act's entry and privacy rules — see our guide on landlord entry and tenant privacy for what proper notice actually requires. A clause requiring a separate, non-refundable "damage deposit" or "pet deposit" on top of a lawful rent deposit generally isn't enforceable either, since the RTA limits what a landlord can collect and how it must be used — our companion piece on how rent deposits actually work covers this in detail.
Other examples include clauses that try to waive a tenant's right to a proper eviction process (for instance, language suggesting a landlord can simply "take back" the unit without an LTB order), clauses that attempt to make a tenant responsible for repairs that are legally the landlord's obligation, or clauses purporting to let a landlord increase rent outside the RTA's timing and guideline rules. In each case, the lease may look formal and specific, but the underlying term is generally unenforceable because it conflicts with a statutory protection.
Common misconception
Some tenants assume that because they signed a lease with a problematic clause, they're stuck with it. In most cases, the opposite is true: the clause itself is generally what's unenforceable, not the tenant's underlying RTA rights.
What a lease can still validly do
None of this means a lease is powerless or that its terms don't matter. A lease can validly set the rent amount, the term length, which utilities are included, parking arrangements, pet policies that don't conflict with human rights obligations, and countless other practical details the RTA doesn't dictate. A lease can also be more generous to a tenant than the RTA requires — for example, promising notice periods longer than the statutory minimum — and that kind of term is generally enforceable, because it doesn't take away a protection, it adds one. The general rule is directional: a lease term that gives a tenant more than the RTA requires is generally fine; one that gives a tenant less is generally the kind of term that won't hold up.
If a clause turns out to be unenforceable
Discovering that a signed lease contains an unenforceable clause doesn't usually void the entire lease — generally, only the conflicting term itself is treated as unenforceable, while the rest of the agreement remains in effect. If a dispute over such a clause reaches the LTB, an adjudicator will generally look at what the RTA actually requires and apply that, regardless of what the lease says on the point. This is part of why disputes over an unusual or restrictive lease clause are often worth raising rather than simply assumed to be binding — see our overviews of tenant rights and landlord rights in Ontario for the baseline protections and obligations the RTA sets for each side.
Why the law is built this way
The floor-not-ceiling structure reflects a policy choice that residential tenancies aren't purely private contracts between equal parties — housing is treated as important enough that certain protections are made mandatory rather than left to negotiation. For landlords, the practical takeaway is that a lease drafted around restricting statutory tenant rights is likely to create problems rather than protection, since those clauses tend not to hold up when tested. For tenants, the practical takeaway is that an unusual or restrictive clause in a signed lease is worth checking against the RTA rather than assumed to be the final word. See our full overview of the Residential Tenancies Act for how its protections fit together, and our glossary for definitions of the terms used throughout this piece.
Why Ontario also has a standard lease form
Because disputes over unclear or restrictive lease language come up so often, Ontario requires most residential tenancies to use a standard, government-issued lease form, rather than a fully custom document drafted by either side. The standard form already builds in the RTA's core protections and clearly marks where additional terms can be added — which makes it considerably harder, in practice, for a problematic clause to be slipped into a lease without either side noticing. Landlords and tenants can still negotiate additional terms within that structure, but the baseline protections are harder to accidentally sign away than they would be with a lease drafted entirely from scratch.
This doesn't mean every lease in Ontario actually uses the standard form correctly, or that older tenancies that began before the standard form became common are automatically problem-free. It does mean that a lease that looks unusually informal, hand-drafted, or missing the standard form altogether is worth a closer look — not because that alone makes it invalid, but because it increases the odds that non-standard, potentially unenforceable terms have been included.
A practical way to check your own lease
For a tenant or landlord wondering whether a specific clause in their own lease is likely to hold up, a useful first step is simply asking what the clause actually takes away, and from whom. A clause that adds detail, sets a practical term, or gives the tenant more than the RTA's minimum is very likely fine. A clause that reduces notice periods, limits a right the RTA grants, or shifts a landlord's legal obligation onto the tenant is the kind of term worth double-checking against the Act, a reliable plain-English resource like this site's guides, or a licensed professional before assuming it's binding. When in doubt, the safest working assumption is the one this article started with: the RTA sets the floor, and no signature lowers it.

Frequently Asked Questions
Generally, no. A lease clause that tries to waive or reduce a tenant's rights under the Act is typically void and unenforceable, even if both parties signed it willingly.
Generally, the Act prevails. Where a lease clause contradicts a minimum protection set out in the Residential Tenancies Act, that clause is typically unenforceable, while the rest of the lease usually remains valid.
A lease may include such a clause, but it's generally unenforceable for most residential tenancies in Ontario, since the Act typically limits a landlord's ability to evict solely over pet ownership (subject to certain exceptions, such as condo board rules or specific safety concerns).
The RTA and municipal bylaws (such as property standards) generally operate alongside each other rather than one simply overriding the other — both can apply to the same rental situation in different ways.
Generally, yes — a lease can provide tenants with greater protections than the Act's minimums (such as requiring more than 24 hours' notice), since the RTA sets a floor, not a ceiling, on tenant protections.
Generally, yes. An unenforceable clause that conflicts with the RTA typically doesn't invalidate the whole lease — the remaining terms usually continue to apply as written.
Only where the Act allows it, and generally only to give the tenant greater protection — not less. Agreements that reduce a tenant's statutory protections are typically not enforceable.
Some arrangements are excluded or only partly covered, such as certain owner-occupied shared accommodations where the owner shares a kitchen or bathroom with the tenant, some care facilities, and some seasonal or commercial properties.
