How to cancel Hydro One and recover your deposit in ontario

Why you might cancel Hydro One

Hydro One Networks Inc. is Ontario's largest electricity distribution utility, serving over 1.4 million residential and business customers across the province. When you move outside Hydro One's service territory, downsize your household, or simply want to close an account, you need a clear, legally-backed process to avoid delays and ensure you recover your security deposit plus accrued interest.

This guide walks you through every step of cancelling Hydro One in Ontario, grounded in the Consumer Protection Act and the Ontario Energy Board's Regulated Price Plan (RPP) framework. Yafee has helped thousands of consumers navigate utility cancellations with confidence, ensuring no deposits are lost and final bills are accurate. Whether you are relocating, transferring service to a new account holder, or ending Budget Billing, you will find the procedural steps, timeline, and your legal position clearly laid out below.

Common reasons for cancellation

You may cancel your Hydro One account for several lawful reasons. Moving to another province or region outside Hydro One's licensed territory is the most common trigger. You might also close an account if a household member relocates and you need to transfer service to a new account holder. Some customers cancel Budget Billing plans when their usage patterns change, or they switch to a time-of-use plan that better suits their schedule. Understanding your cancellation reason helps you provide the correct notice to Hydro One and speeds up the final meter reading and refund process.

Your consumer rights under ontario law

Your cancellation rights are protected under Ontario's Consumer Protection Act and the Regulated Energy Network Code administered by the Ontario Energy Board. You have the right to cancel service at any time by providing written notice to Hydro One. The utility must schedule a final meter reading within a reasonable timeframe (typically 10 to 14 business days) and issue a final bill. You are entitled to a full refund of your security deposit plus accrued interest within 4 to 6 weeks of account closure. Hydro One cannot impose early termination fees, disconnect penalties, or administrative charges for cancelling as a residential customer.

Your legal position: Under section 29 of Ontario's Consumer Protection Act, you may cancel any consumer agreement by written notice at any time. The Ontario Energy Board enforces residential utility standards, and Hydro One must comply with the Regulatory Framework for Price-Controlled Utilities. If Hydro One refuses to refund your deposit or charges an unlawful fee, you may escalate your complaint to the Ontario Energy Board's Consumer Relations office or seek remedies through Small Claims Court.

Hydro One rate plans and billing options

Understand your current plan to confirm what you are cancelling and whether a final bill adjustment is coming.

Budget billing and final reconciliation

If you are enrolled in Budget Billing, your monthly payment is fixed based on a 12-month usage forecast. When you cancel, Hydro One reconciles your account: if you have overpaid, you receive a credit on your final bill or a refund cheque. If you have underpaid, you owe the difference on your final invoice. This reconciliation happens automatically when your account closes, so review your final bill carefully to confirm the calculation is correct.

How to cancel your Hydro One account

Follow these steps to cancel your account in writing, ensuring Hydro One processes your request promptly and schedules a final meter reading.

Step 1: gather your account details

Locate your Hydro One bill and note your account number (a 12-digit identifier printed in the top-right corner). You will also need the service address, the date you want cancellation to take effect, and your forwarding address for the final bill and deposit refund cheque. Keep a copy of your current bill handy; it contains all the information Hydro One needs to close your account accurately.

Step 2: write and send your cancellation notice

Submit your cancellation request in writing via registered mail to Hydro One's billing and service address. Use clear, direct language in your letter. Include your account number, the service address, your cancellation effective date, and your forwarding address. Request a final meter reading and confirmation of your security deposit refund amount and timeline.

Mail your signed cancellation letter to:

Hydro One
P.O. Box 5700
Toronto, Ontario M5G 2N5
Canada

Send your letter via Canada Post Registered Mail with a Return Receipt (this provides proof of delivery if Hydro One disputes whether they received your cancellation request). Keep the tracking number and receipt confirmation.

Step 3: confirm receipt and follow up

Within 10 business days of mailing your cancellation letter, contact Hydro One's customer service at 1-888-664-9376 (or 1-416-345-5700 in Toronto) to confirm Hydro One has received your written request and to schedule the final meter reading. Provide your account number and the date you mailed your cancellation notice. Ask for a reference number or confirmation email, and request a specific meter-reading appointment date. Do not rely on a single phone call; written confirmation is your legal protection if a dispute arises.

Step 4: prepare for the final meter reading

Hydro One will contact you to schedule a final meter reading appointment, typically within 14 business days of receiving your cancellation notice. Ensure someone is present at the service address on the scheduled date, or arrange for Hydro One to access the meter if it is outside your home. The meter reader will photograph or record the final reading, and Hydro One will use this reading to calculate your final bill. If you are not present and Hydro One cannot access the meter, they may issue an estimated final bill, which you can dispute if you provide a photo of your meter on the cancellation date.

Step 5: receive and review your final bill

Hydro One will issue your final bill within 2 to 4 weeks after the meter reading. This bill includes charges for electricity consumed up to the final reading date, plus any applicable taxes and fees, minus your security deposit refund plus accrued interest. Review the final bill carefully: check that the meter reading is correct, that you are not charged any early termination or disconnection fee (which would be unlawful for residential customers), and that your deposit is credited in full. If you are on Budget Billing, confirm that the account has been reconciled and any overpayment is shown as a credit.

Step 6: verify your deposit refund

Your security deposit refund will be mailed separately as a cheque or credited to your final bill, depending on Hydro One's process. The refund must include interest accrued on your deposit at the rate set by the Ontario Energy Board (currently around 1.75% annually, but check your final bill documentation). The full refund and interest must arrive within 6 weeks of account closure. If you do not receive your refund cheque within this timeframe, contact Hydro One's billing department immediately and request a refund status. Keep a copy of your final bill and all correspondence for your records.

Timeline for cancellation and refund

Understanding the timeline helps you plan your move and manage your finances during the transition.

This timeline assumes Hydro One receives your notice promptly and schedules the meter reading without delay. If you face unexpected delays, escalate to Hydro One's customer service or file a complaint with the Ontario Energy Board.

Common mistakes to avoid when cancelling

Cancellation is straightforward, but a few common missteps can delay your refund or leave you with unexpected charges. Here is how to avoid them.

Not sending written notice

Calling Hydro One verbally to cancel is not sufficient. Ontario's Consumer Protection Act requires written notice, and Hydro One's service terms require written cancellation requests. Always send your cancellation letter via registered mail to create a paper trail. If you call first, follow up with a mailed letter within 48 hours. Yafee recommends treating your cancellation as a formal legal notice, not a casual conversation.

Sending to the wrong address

Hydro One's head office is located at 483 Bay Street in Toronto, but this address is not monitored for cancellation requests. Always mail your cancellation notice to P.O. Box 5700, Toronto, Ontario M5G 2N5. Sending to the head office may delay processing by weeks. Use registered mail to confirm delivery.

Failing to provide a forwarding address

If you do not include your forwarding address in your cancellation letter, Hydro One may not know where to send your final bill and deposit refund cheque. Use a clear, complete forwarding address (including postal code) and provide an email address or phone number where Hydro One can contact you if clarification is needed.

Not following up on the meter reading

If you miss the meter reading appointment or Hydro One cannot access the meter, they will issue an estimated final bill. Disputes over estimated readings can delay your refund by several weeks. Confirm your appointment, ensure access to the meter, and consider providing a photo of the meter on your cancellation date as backup evidence.

Accepting an inaccurate final bill without objection

Review your final bill line by line. If you see an early termination fee, a reconnection charge, or a metre reading that seems incorrect, contact Hydro One in writing (not by phone) within 10 days and request a correction. Yafee advises keeping scans of your final bill and all correspondence in case you need to file a dispute later.

After your account closes

Once your account is cancelled and your meter reading is complete, a few administrative steps remain to ensure a clean exit.

Confirm your new provider is activated

If you are moving to another utility company's service territory, confirm that your new provider's account is activated before your Hydro One account closes. There should be no gap in service; electricity must flow continuously. Contact your new provider at least 14 days before your cancellation date to schedule activation. Hydro One will disconnect your account only after the final meter reading; your new provider will energize your service on the same or the next business day.

Monitor your forwarding address

Your final bill and deposit refund cheque will arrive at the forwarding address you provided. If you are moving to a temporary address during your relocation, update your address with Canada Post or provide Hydro One with contact information for a trusted friend or family member who can forward documents to you. Do not assume the cheque will arrive within 6 weeks; monitor your mail carefully.

Dispute or verify the refund amount

Once you receive your deposit refund cheque, verify that it matches the deposit amount shown on your final bill plus accrued interest. If the refund is less than expected, contact Hydro One's billing department and request an itemized explanation. Ask for documentation of the interest calculation. If Hydro One refuses to refund the full amount, you may file a complaint with the Ontario Energy Board's Consumer Relations office or pursue a claim in Small Claims Court.

If Hydro One refuses to process your cancellation

Rarely, Hydro One may dispute a cancellation request or delay processing without cause. Here is how to escalate.

Contact customer service in writing

If Hydro One does not acknowledge your cancellation notice or schedule a meter reading within 14 days, send a follow-up letter (again via registered mail) to the same P.O. Box address. Reference your original cancellation date, account number, and tracking number from your first mailing. Request a written response confirming receipt and a scheduled meter reading appointment within 5 business days.

File a complaint with the ontario energy board

If Hydro One continues to delay or refuses cancellation, file a formal complaint with the Ontario Energy Board's Consumer Relations office. You can submit a complaint online via the Ontario Energy Board's website (oeb.ca) or by mail. Provide copies of your cancellation notice, registered mail receipts, phone records, and any correspondence from Hydro One. The Ontario Energy Board will investigate whether Hydro One has violated the Regulated Energy Network Code or Ontario's Consumer Protection Act, and may order Hydro One to process your cancellation immediately and refund any unlawfully withheld deposits.

Pursue legal remedies

If the Ontario Energy Board's complaint does not resolve the matter, you may file a claim in Small Claims Court for the amount of your security deposit plus interest, plus damages for any costs you incurred (such as duplicate electricity bills or moving expenses due to delayed service disconnection). Small Claims Court handles disputes up to $35,000, making it an accessible option for deposit refunds. Consult a paralegal or contract lawyer if the amount is substantial or the facts are complex.
