Disputing Hydro Bills with the OEB: Ontario Tenant Guide

Utilities & Services Ontario 3 min read · published March 29, 2026 Flag of Ontario

Many renters in Ontario receive hydro bills that feel incorrect or that include charges they believe are the landlords responsibility. If you are a tenant worried about meter readings, billing errors, estimated consumption, or third-party collection for utilities, you can raise the issue with your supplier and, if unresolved, ask the Ontario Energy Board (OEB) to review the matter. This guide explains what tenants should document, how to file a complaint, which official forms and deadlines apply, and what to expect from the review process. It also clarifies where tenancy laws intersect with utility obligations so you can protect your rights and avoid paying for charges that are not yours.

Who handles hydro billing disputes in Ontario?

The Ontario Energy Board is the regulator for electricity suppliers and handles complaints about billing and customer service[1]. If a bill relates to meter reads, estimated consumption, or incorrect rates, contact your hydro utility first and ask for an investigation. If the utility does not resolve it, you may file a formal complaint with the OEB using its complaint form[2]. For disputes that overlap with tenancy issues—like who pays for common-area or unit-supplied electricity—your Landlord and Tenant Board handles tenancy disputes and the Residential Tenancies Act, 2006 explains obligations under Ontario law[3][4].

In most regions, tenants are entitled to basic habitability standards.

When to dispute a hydro bill

  • Bill amount seems unusually high compared to your normal usage.
  • Charges include an amount you believe your landlord should pay under the lease.
  • Estimated reads were used and you can provide actual meter reads to show the billed amount is wrong.
  • There are duplicate charges, unexplained adjustments, or late fees appearing after billing disputes.
Respond to billing notices promptly to protect your rights.

How to prepare your complaint

Gather the documents and records that will show the utility where an error or misallocation occurred.

  • Keep dated meter readings, photos of the meter display, and comparison logs showing normal usage.
  • Save all billing statements, receipts for payments, and any correspondence with the utility or landlord.
  • Note dates and summaries of phone calls, names of representatives, and any reference or file numbers the utility gives you.
  • Collect the relevant lease clauses that mention utilities; see What Tenants Need to Know After Signing the Rental Agreement for common clauses tenants should check.
Detailed documentation increases your chances of success in disputes.

Step-by-step: Filing with the OEB

  1. Contact your hydro utility first and request a billing investigation; ask for a reference number and timeline.
  2. Complete the OEB complaint form online or in writing and attach copies of your evidence to support the claim[2].
  3. Keep a record of OEB correspondence and meet any deadlines the board sets while it reviews your file.
  4. If the issue also involves who is contractually responsible for utilities, consult the Landlord and Tenant Board about tenancy remedies under the Residential Tenancies Act[3][4].
  5. Attend any meetings or hearings and be prepared to present your records; keep copies of outcomes and next-step instructions.
