Can a Landlord Evict a Tenant for Installing a Bidet That Causes a Leak in Ontario?

Yes, a landlord in Ontario can issue an N5 eviction notice if a tenant’s unauthorized DIY bidet installation leaks and causes property damage. However, the tenant has the legal right to void this notice within 7 days by paying for the repair costs of the water damage and returning the plumbing to its original state.

Bidet attachments have become incredibly popular across Canada. They are cheap to buy online and seem easy to install. However, connecting aftermarket plumbing to an apartment toilet without professional help carries massive risks. In multi-story buildings in Toronto, Waterloo, or Kingston, a single botched bidet installation can cause thousands of dollars in water damage to the unit below yours.

Landlords are understandably furious when unauthorized alterations destroy flooring and drywall. 📍 Under the Residential Tenancies Act, causing undue damage to the rental property is a highly valid reason for eviction. This guide outlines how landlords can legally proceed when a tenant’s DIY project goes wrong, and how a tenant can save their tenancy by making things right. If the damage is catastrophic, reaching out to a paralegal from our directory is essential.

Step-by-Step Process for Eviction Due to Property Damage

Evicting a tenant for property damage is a strict, structured process. Landlords cannot simply throw a tenant out the moment they spot a leak. Following these steps ensures compliance with the Landlord and Tenant Board (LTB).

Step 1: Stop the Leak and Assess the Damage

The immediate priority is mitigating the loss. The landlord or their emergency plumber must enter the unit (which is permitted without 24 hours notice in the event of an active flood) to turn off the water supply. 💧 Take clear photographs and videos of the bidet, the disconnected water lines, and all resulting damage to the floors, baseboards, and any units underneath.

Step 2: Obtain Professional Repair Quotes

Before issuing any legal notices, the landlord must know exactly how much the tenant owes. Have a licensed contractor assess the water damage and provide a detailed, written estimate for the repairs. You will need this exact dollar figure for the legal forms.

Step 3: Serve the Form N5 Notice

The landlord must serve a Form N5 (Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding). 📝 On this form, the landlord must clearly detail the unauthorized bidet installation, the extent of the damage, and the exact amount of money the tenant must pay to cover the contractor’s repair quote.

Step 4: The 7-Day Void Period

This is critical: the tenant has exactly seven days to “void” the N5 notice. If the tenant pays the full repair amount listed on the form to the landlord within these 7 days, the eviction notice becomes legally void. The tenant gets to stay, provided they also remove the unauthorized bidet.

Step 5: File the L2 Application if Unresolved

If the tenant refuses to pay for the damage within the 7-day window, the landlord can proceed to file an L2 Application to End a Tenancy and Evict a Tenant with the LTB. ⚔️ At the hearing, the adjudicator will review the plumbing evidence and decide whether the eviction should be enforced or if the tenant should be given a final payment plan.

How Much Does it Cost in Ontario?

Water damage is notoriously expensive, and DIY plumbing mistakes can quickly escalate into major financial liabilities for both parties.

  • LTB Filing Fee: To file the L2 Application, the landlord must pay $201 CAD.
  • Water Damage Repairs: Fixing ruined laminate flooring, drywall, and ceilings in lower units easily ranges from $1,500 to $10,000+ CAD, depending on the severity of the leak.
  • Legal Representation: Hiring a paralegal to manage the N5 and L2 hearing typically costs $800 to $2,000 CAD.
Potential ExpenseEstimated Cost (CAD)Who Pays?
Contractor Repair Bill$1,500 – $10,000+Tenant (or Landlord’s insurance if tenant defaults).
L2 Filing Fee$201Landlord upfront (Tenant may be ordered to reimburse).
Professional Plumber$150 – $400Tenant (To fix the toilet connection properly).

How Long Does the Process Take?

Evictions for damage require patience from landlords, as the LTB system is heavily backlogged.

  • Voiding Period: The tenant is legally granted 7 days to pay for the damages to void the N5 notice.
  • Notice Termination Date: The termination date on the N5 notice must be at least 20 days after it is served.
  • Hearing Wait Time: Getting an L2 hearing date for property damage typically takes 5 to 8 months in Ontario.

Frequently Asked Questions (FAQ)

Am I allowed to install a bidet if it doesn’t leak?

Generally, modifying plumbing without the landlord’s written consent is a breach of the standard lease agreement. Even if it does not leak immediately, a landlord can serve an N5 requiring you to remove the unauthorized alteration and restore the toilet to its original state.

Can the landlord’s insurance cover the damage?

Yes, the landlord can claim the damage through their property insurance. However, the insurance company may then subrogate (sue) the tenant directly to recover the payout because the tenant’s negligence caused the loss.

Do I need tenant insurance for this?

Absolutely. This is exactly why landlords require tenant liability insurance. If your DIY bidet leaks and destroys the unit below, your tenant liability insurance will cover the massive repair bills, saving you from personal bankruptcy and eviction.

What happens if I get a second N5 notice?

If you void the first N5 by paying for the damage, but cause more damage and receive a second N5 within 6 months, the second notice is non-voidable. You cannot simply pay to cancel it, and the landlord can proceed straight to an eviction hearing.
