Changing Locks in Ontario: Tenant and Landlord Rights

Evictions Ontario published: June 10, 2025 Flag of Ontario

For tenants renting in Ontario, questions around changing the locks are common—especially when there are security concerns or conflicts with a landlord. Understanding who is allowed to change the locks and when is crucial to avoiding legal trouble and ensuring your home remains safe and accessible.

Who Can Change the Locks? Ontario Law Explained

The Residential Tenancies Act, 2006 sets clear rules for changing locks in rental units:

  • Neither tenants nor landlords can change locks without the other's consent or an order from the Landlord and Tenant Board (LTB).
  • If either party changes the locks, they must provide keys to the other party right away.

For example, if your landlord decides to upgrade the locks, they must immediately give you a working key to the new lock. The same applies if you change the locks—for instance, after a break-in or for personal safety—you must give your landlord a new key.

Legal Reference and Tribunal

These rules are enforced by the Landlord and Tenant Board (LTB) of Ontario. Violating them can lead to orders for damages or even eviction.

When Can a Tenant Change the Locks?

Tenants may only change locks in limited situations:

  • With written landlord permission
  • When ordered by the Landlord and Tenant Board
  • In emergencies (e.g. after police advise for immediate safety), but you must still provide the landlord a new key as soon as possible
Changing locks without consent or without giving a new key can result in a landlord filing to evict you—even if your reasons feel justified. Always communicate promptly about lock changes.

If The Landlord Changes the Locks Without Warning

If your landlord changes the locks and doesn't give you a new key, this is called an "illegal lockout," which is prohibited under Ontario law. You have the right to apply to the LTB for an order to regain access, and the landlord may face penalties.

What Forms and Actions Are Involved?

  • Tenant Application About Maintenance (Form T6): Used if your landlord refuses to repair or replace locks, impacting your security. Find Form T6 on the Ontario Tribunals website. Tenants use this to ask the Board to order the landlord to take appropriate action and/or pay compensation.
  • Application About Tenant Rights (Form T2): Used if your landlord locks you out or changes the locks without giving you a key. Download Form T2 (Application About Tenant Rights). This helps you regain access and may entitle you to damages.

Both forms are submitted to the LTB. Fill them out with as much detail as possible, including dates, times, and any communications with your landlord.

Landlord and Tenant Responsibilities Around Locks

Both tenants and landlords share the responsibility for keeping the rental unit secure and accessible. For a full breakdown of each side's legal duties beyond just locks, see Obligations of Landlords and Tenants: Rights and Responsibilities Explained.

Emergencies and Safety Concerns

If you change the locks due to threats to your safety (such as after police involvement or immediate risk), you must still provide the landlord with a new key right away. Document your reasons and communications with your landlord.

Always save written proof (emails, police reports, or texts) about your reasons for changing locks and your offer to provide a key. This can protect your rights if a dispute arises.

How Lock Changes Affect Moving Out

If you're moving out and want to change the locks in your last days, the same laws apply, and you still need landlord consent and must provide them a new key. This is true whether your departure is planned or after an eviction notice has been given. For overall moving processes, see Moving Out Tips: A Tenant's Guide to a Smooth Rental Exit.

Other Practical Considerations

  • Changing locks does not affect your responsibility to pay rent or meet the lease terms.
  • Unauthorized lock changes can result in compensation claims or eviction orders from the Board.
  • If your landlord claims emergency access is needed (e.g., for repairs), you cannot refuse if proper notice is provided.
