A2 Application

Evicting an Illegal Occupant in Ontario

Sometimes a tenant moves out…but someone else refuses to follow. Whether it’s a roommate, partner, or friend who was never approved to live there, unauthorized occupants can quickly become a major headache for landlords. The good news? Ontario’s Landlord and Tenant Board (LTB) has a specific process designed to help you regain control of your property. It’s called the A2 Application — and if used properly, it ensures a fast, lawful eviction through the Board and the Sheriff.

Evicting an Illegal Occupant in Ontario: What Landlords Need to Know About the A2 Application

If you’re a landlord in Ontario, there may come a time when a frustrating situation arises: your tenant moves out, but someone else refuses to leave. It could be a friend, roommate, partner, or family member — someone who was never officially on the lease and never had your permission to live in the unit.

Thankfully, Ontario’s Landlord and Tenant Board (LTB) provides a clear legal pathway to help you regain control of your property. That’s where the A2 Application comes in.

✅ What Is the A2 Application?

The A2: Application About an Agreement Between a Landlord and Tenant is used when:

  • The original tenant has legally moved out, and
  • A person still occupying the rental unit was never authorized by the landlord to stay there.

This gives landlords a lawful mechanism to have the unauthorized occupant removed through the LTB and the Sheriff, rather than taking matters into their own hands — which could expose landlords to legal risk.

🏠 When Should a Landlord Use an A2 Application?

The A2 Application is appropriate when:

  • The legitimate tenancy has already ended
  • A subtenant or guest remains without permission
  • The unauthorized occupant refuses to leave voluntarily

This application confirms that the person living there has no legal right to remain on the premises.

⚠️ Why Not Just Change the Locks?

In Ontario, landlords cannot forcibly remove someone — even if they were never a tenant. Actions like:

  • Changing the locks
  • Removing belongings
  • Shutting off utilities
  • Intimidating the occupant

…can result in serious penalties under the Residential Tenancies Act (RTA).
Only the Sheriff can carry out an eviction once the LTB issues an eviction order.

📝 What Happens After Filing?

Once filed with the LTB:

  1. A hearing date is scheduled
  2. The unauthorized occupant is served with notice
  3. The Board reviews evidence confirming the tenancy has ended
  4. If approved — an eviction order is issued
  5. The Sheriff enforces the eviction legally

This process protects your rights as a landlord while ensuring the eviction is handled properly.

👋 Need Help Navigating This Process?

Dealing with an unknown or unauthorized occupant can be stressful — but you do have options. Understanding the A2 Application ensures you stay compliant with the law while taking the right steps to protect your property.
