When a rental agreement is assigned in Ontario, unpaid electricity, water, gas, or other utility charges can create confusion for the outgoing tenant, incoming tenant, landlord, and utility provider. Responsibility usually depends on the lease, the assignment agreement, the date possession changed, and whose name was on the utility account. A renter should not assume that an assignment automatically erases every earlier debt or makes them responsible for charges incurred by someone else. This guide explains how utility liability may be assessed, what records to gather, how Ontario tenants can respond to a demand or notice, and where to get help with a residential tenancy dispute.
How an assignment affects utility responsibility
An assignment transfers a tenant's interest in the rental unit to another person, who generally takes over the tenancy on the agreed effective date. The written assignment should identify that date, the parties, the rent, and how utilities will be handled. It is also important to ask the landlord and utility provider to confirm the account transfer or final meter reading.
The outgoing tenant may remain exposed to charges that arose before the assignment, especially if the utility account stayed in that tenant's name or the lease makes the tenant responsible for the account. The incoming tenant is generally responsible for charges connected with their own occupancy and agreement, but the exact result depends on the contract, account records, and proof of when responsibility changed.
Ontario's Residential Tenancies Act, 2006 governs residential tenancies, while the utility provider's contract and billing records may determine who was billed directly. The Landlord and Tenant Board can decide disputes between landlords and tenants, but it may not resolve every contract dispute between a renter and an independent utility company.
When an outgoing tenant may still owe money
An outgoing tenant may face a claim for unpaid utilities when the charges relate to their occupancy, the lease clearly assigned those costs to them, or they failed to close or transfer an account as required. A landlord may also claim an amount through the tenancy process if the utility charge is treated as rent or as a charge permitted by the agreement and law. A demand alone does not prove that the amount is correct.
- Check whether the lease identifies utilities as rent, a separate charge, or the tenant's direct account.
- Compare invoices, meter readings, payment receipts, and the assignment date.
- Ask for an itemized statement showing the billing period, amount, and basis for the claim.
Do not withhold ordinary rent simply because a utility balance is disputed. A tenant who receives a notice alleging rent arrears should read it carefully and obtain advice promptly.

When an incoming tenant may be responsible
The incoming tenant should usually be responsible for utilities beginning on the assignment or possession date if the agreement places those costs on that tenant. They should not normally be charged for the outgoing tenant's earlier consumption merely because the account was not transferred promptly. A tenant can ask the landlord for a move-in meter reading and request that the utility provider separate the billing periods.
If the assignment agreement says the incoming tenant will reimburse a prior balance, that term should be reviewed carefully before signing. A private agreement between tenants may not bind a utility provider or change the landlord's rights under the tenancy agreement. The safest approach is to record the exact amount accepted, the period covered, and whether the payment is a final settlement.
What to do if you receive a utility claim or notice
- Read the lease, assignment agreement, and any notice to identify the legal basis and response deadline.
- Collect utility bills, account-transfer confirmations, meter photos, emails, payment records, and possession evidence.
- Contact the landlord or utility provider in writing and request an itemized calculation limited to the relevant billing period.
- Respond to any Landlord and Tenant Board application or notice using the required process rather than ignoring it.
- Meet every deadline and obtain legal or community assistance promptly if you cannot resolve the account.
Ontario forms and dispute options
The Landlord and Tenant Board's official forms page provides current forms and filing instructions. A tenant may use Form A2, Application about a Sublet or an Assignment, when asking the Board to determine an issue involving an assignment or an unreasonable refusal. For example, a tenant who requested an assignment and was refused without a lawful reason may use A2 to ask for a remedy; it is not a general form for every utility bill dispute.
If a landlord serves Form N4, Notice to End your Tenancy Early for Non-payment of Rent, the tenant should check whether the claimed utility amount is legally part of rent under the agreement and respond before the notice deadline. For example, a renter disputing a charge for electricity used after the assignment date should gather the transfer confirmation and raise that issue through the appropriate response or application process.

Protecting yourself before and after an assignment
- Keep a signed copy of the assignment and written confirmation of the effective date.
- Take dated meter or utility-device photos when possession changes.
- Request written confirmation that your utility account was closed or transferred.
- Keep receipts and do not agree to a balance without checking the billing period.

- Who pays a utility bill covering both sides of an assignment?
- The parties should ask the provider to divide the bill using actual readings or a reasonable documented allocation based on the assignment date and occupancy.
- Can a landlord include unpaid utilities in an Ontario rent-arrears notice?
- Sometimes, depending on the tenancy agreement and how the charge is treated under Ontario law, but a tenant should review the claim and respond promptly rather than assume it is valid.

- Form A2 is an application about a sublet or assignment, including certain disputes about an assignment or a landlord's refusal, and is filed with the Landlord and Tenant Board.
