Ontario Tenant Guide: Natural Gas Billing Disputes

Utilities & Services Ontario 3 min read · published March 09, 2026 Flag of Ontario

As a tenant in Ontario, a surprising or high natural gas bill can be stressful and confusing. This guide walks renters through practical steps to check meter readings, compare billing periods, and gather documentation before contacting a gas utility or your landlord. You’ll learn when to request an explanation, which official forms and tribunals can help, and how to present evidence clearly if a dispute reaches the Landlord and Tenant Board or the Ontario Energy Board. The advice is written for non-experts and focuses on preserving your rights, meeting deadlines, and avoiding unnecessary payment while a legitimate dispute is investigated. Keep records of conversations, photos of meters, and copies of bills to strengthen your case.

How natural gas billing disputes arise

Gas billing disputes usually come from a few common issues. Sometimes meters are read incorrectly or providers use estimates. Other times landlords pass through charges incorrectly or there are billing-system errors. Understanding the likely causes helps you choose the right next step and the correct official body to contact.

  • Incorrect or estimated meter readings
  • Charges or passthroughs added by a landlord that don’t match usage
  • Billing period overlaps or duplicate charges
  • Errors from the utility or account misallocation
Detailed documentation increases your chances of success in disputes.

What tenants should do first

Follow a clear order: verify your meter, collect your bills, contact the utility, and inform your landlord in writing. If those steps do not resolve the issue, the Landlord and Tenant Board and the Ontario Energy Board provide formal complaint and application routes depending on whether the dispute is about a tenancy charge or a utility billing error.

  • Record the current meter reading and date (take a photo with a timestamp if possible).
  • Gather past bills, account statements and any emails or messages about charges.
  • Contact your gas utility to request an explanation or correction and note the date, agent name and reference number.
  • Notify your landlord in writing (email or letter) with the facts, copies of evidence and a clear request for correction or clarification.
Keep copies of bills and meter photos in one folder.

If communication with the utility does not fix the bill, you may need to use formal complaint routes. For utility billing problems contact the Ontario Energy Board and for tenancy-related billing (for example, where a landlord is charging tenants improperly) consider the Landlord and Tenant Board.[3][1]

FAQ

How long do I have to dispute a gas bill?
Timelines vary: contact your utility promptly and follow their complaint process; for tenancy-related billing disputes check deadlines under the Residential Tenancies Act, 2006 and apply to the Landlord and Tenant Board as needed.[3][2]
Should I pay the disputed amount while I investigate?
Paying the undisputed portion protects your account; if you withhold payment, document reasons and seek advice because non-payment for legitimate charges can affect tenancy or utility service.
What if my landlord refuses to correct an error they charged me for?
If the charge is part of your tenancy (for example, an itemized utility passthrough) you can apply to the Landlord and Tenant Board to dispute the charge and request repayment or adjustment.[1]

How-To

  1. Document the issue: copy bills, note meter readings and take dated photos.
  2. Contact the gas utility: request an itemized explanation and a formal review. Keep reference numbers and staff names.
  3. File a formal complaint or, if tenancy charges are involved, submit an application to the Landlord and Tenant Board with evidence.
  4. Prepare for a hearing: organize bills chronologically, include photos and a clear timeline; bring copies for the board and landlord or utility.

Key Takeaways

  • Document meter readings and keep dated photos and bills.
  • Contact your utility first, then notify your landlord in writing if charges relate to tenancy.
  • Use official complaint and tribunal routes if informal resolution fails.
