Cancel Hydro One: The Right Way

How to cancel Hydro One and reclaim your deposit in ontario

Understanding Hydro One and your right to cancel

Hydro One Networks Inc. is Ontario's largest electricity transmission and distribution utility, serving millions of residential and business customers across the province. You depend on Hydro One to deliver power to your home or business, manage your meter readings, process your monthly bills under the Ontario Energy Board's Regulated Price Plan, and hold your security deposit. When you move outside Hydro One's service territory, change providers, or simply decide to close your account, you have clear legal rights that protect you from hidden fees and ensure you recover what you are owed.

At Tocancel, we help thousands of consumers navigate utility cancellations with confidence and clarity. Whether you are relocating across Canada, switching to a competitive energy provider, or transferring service to a new account holder, this guide walks you through every step-from written notification to final refund-so you avoid costly delays and recover your full deposit plus accrued interest.

Why you might cancel Hydro One

You may cancel your Hydro One account for several legitimate reasons. Moving out of Hydro One's service territory is the most common trigger; Ontario's regulated utilities serve specific geographic zones, and leaving that zone means you must end service. You might also cancel if a household member moves out and you need to transfer service to a new account holder. Some customers cancel Budget Billing plans when their spending patterns change. Others switch to a competitive energy retailer within Ontario's deregulated market. Tocancel has guided thousands of consumers through these transitions, ensuring no deposit is lost in the process.

Your consumer rights under ontario law

Your cancellation rights are protected under Ontario's Consumer Protection Act and the Regulated Energy Network Code enforced by the Ontario Energy Board (OEB). You have the unconditional right to cancel residential 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. You are entitled to a refund of your full security deposit plus accrued interest within several weeks of account closure. Hydro One cannot impose early termination fees, penalties, or contract-break charges on residential customers cancelling due to relocation.

Your legal position: If Hydro One refuses to refund your deposit or charges you a cancellation fee, you can file a complaint with the Ontario Energy Board at no cost. Business customers may face different contractual terms, so always request a copy of your service agreement before submitting cancellation.

Hydro One pricing and rate plans explained

Understanding your current rate plan helps you anticipate any final bill adjustments and confirm which option you are cancelling.

If you are on Budget Billing, your final bill will reconcile any overpayment or underpayment against your actual usage through the cancellation date. This means you may receive a credit or owe an adjustment when you close your account. Tocancel recommends requesting a detailed usage summary from Hydro One at least 10 days before your intended cancellation date so you can anticipate the final bill amount.

Cancellation methods and step-by-step instructions

Hydro One accepts cancellation notices by registered mail to its billing department. This is the most reliable method because it creates a documented record of your request and proof of delivery.

How to cancel by registered mail

Registered mail (with return receipt) ensures Hydro One receives your cancellation request and you have proof of delivery. This protects you if there are later disputes about when you submitted your notice.

1. Gather your account information.
   • Locate your Hydro One account number (printed on your most recent bill).
   • Write down your full address as it appears on the account.
   • Note your preferred cancellation date (typically 10 to 21 days in the future to allow for meter reading).
2. Draft a cancellation letter.
   • Address it to Hydro One, Billing Department, P.O. Box 5700, Toronto, Ontario, M5K 2M6.
   • Include your account number, full name, service address, and phone number.
   • State your cancellation date clearly: "I request that my Hydro One account be cancelled effective [date]."
   • Request a final meter reading and a confirmation of your security deposit refund.
   • Ask for a final bill to be mailed to your new address.
   • Print and sign the letter in black or blue ink.
3. Send via Canada Post registered mail.
   • Visit your local Canada Post office with the signed letter and your account details.
   • Request Registered Mail service with a return receipt (Signature on Delivery).
   • Keep the tracking number and return receipt for your records.
   • Expect delivery confirmation within 5 to 10 business days.
4. Confirm receipt with Hydro One.
   • Once the return receipt arrives, call Hydro One Customer Service at 1-888-664-9376 to confirm they received your cancellation request.
   • Provide your account number and the date you mailed the letter.
   • Ask them to confirm the cancellation date and provide a reference number.
5. Schedule your final meter reading.
   • Hydro One will contact you within 5 business days to schedule a final meter reading at your home.
   • Ensure someone is present or provide alternative access instructions.
   • Ask the meter reader for a final reading confirmation and any notes about the account.

What to include in your cancellation letter

A clear, complete cancellation letter prevents misunderstandings and delays. Your letter should state your account number, full service address, desired cancellation date, request for a final meter reading, and confirmation that your security deposit will be refunded. Tocancel recommends keeping a photocopy of your signed letter before mailing and attaching it to your return receipt tracking confirmation. This documentation protects you if Hydro One later claims they never received your request.

Timeline and what to expect after cancellation

Knowing the typical timeline helps you plan your move and avoid service interruptions or missed refunds.

Typical cancellation timeline

From the moment Hydro One receives your registered letter, the process unfolds in predictable stages. They will acknowledge receipt within 2 to 3 business days and contact you to schedule a final meter reading within 5 to 10 business days. The meter reading itself occurs within 10 to 21 days of your cancellation request. After the final reading, Hydro One reconciles your account, calculates any refund or adjustment, and mails your final bill within 10 to 15 business days. Your security deposit refund, plus accrued interest, typically arrives within 30 days of account closure. In total, expect the full cancellation process to take 6 to 8 weeks from the moment you send your registered letter.

After your account closes

Many people feel uncertain in the weeks after cancelling, especially if they have not yet received their refund. This is normal-utilities process thousands of closures monthly, and delays do happen. However, you have clear remedies if Hydro One falls short. Once your account is officially closed, Hydro One must send you a final bill statement showing your security deposit balance, any accrued interest, and the refund amount owed. If you do not receive your final bill within 30 days of your last meter reading, contact Hydro One again with your reference number and tracking details. Tocancel recommends checking your mail regularly and setting a calendar reminder to follow up 45 days after your meter reading if the refund has not arrived.

Security deposit refunds and final bill adjustments

Your security deposit is your money, and Ontario law requires Hydro One to return it with interest.

How your refund is calculated

When you cancel, Hydro One calculates your security deposit refund as follows: they return your original deposit amount plus accrued interest at the rate set by the Ontario Energy Board (currently around 2.4% annually). They also reconcile your final bill based on actual usage through the cancellation date. If you overpaid during your last billing cycle, that credit is added to your refund cheque. If you underpaid, the shortfall is deducted. Budget Billing accounts often see larger adjustments because the 12-month estimated payment may differ significantly from actual usage.

Example: You paid a $300 security deposit 18 months ago. You are owed $300 plus interest of approximately $9 (18 months at 2.4% annually). Your final bill shows a $45 overpayment credit. Your refund cheque will be approximately $354.

Disputing a refund or final bill

If you believe your refund is incorrect or your final bill contains errors, you have the right to dispute it. Contact Hydro One in writing within 30 days of receiving your final bill. Reference your account number, the specific line items you dispute, and your evidence (such as meter readings or previous bills showing usage patterns). If Hydro One refuses to adjust the amount, you can file a formal complaint with the Ontario Energy Board at no cost. The OEB will investigate and issue a binding decision. Tocancel has helped many consumers recover lost deposits by providing clear documentation and escalating disputes to the OEB when necessary.

Common cancellation mistakes and how to avoid them

Cancelling a utility account feels stressful, especially when you are already managing a house move. The mistakes most people make are avoidable with a little planning.

Not cancelling early enough

If you cancel just days before moving, Hydro One may not complete your final meter reading before you lose access to your property. This creates a billing dispute and delays your refund. Always cancel at least 14 days before your planned move date. If you are selling or renting out your property, coordinate cancellation timing with the new owner or tenant to ensure meter access.

Failing to document your cancellation request

Phone calls to Hydro One are not documented proof of cancellation. Always send your request by registered mail so you have a return receipt. If you call, ask for a confirmation number and the date you called, then follow up with a registered letter within 48 hours. Tocancel strongly advises against email or online chat cancellations for utility accounts because Ontario utilities require formal written notice, and digital records are easier to dispute.

Not requesting a final meter reading confirmation

Without a meter reading, Hydro One may estimate your final bill, which can lead to overcharges or underpayments that delay your refund. Always ask the meter reader to provide a written confirmation of the reading, and request a copy from Hydro One in writing after the reading is complete.

Ignoring your final bill

Some people assume their refund is automatic and do not review their final bill carefully. Always open your final bill, check the security deposit amount, verify the interest calculation, and confirm the refund total. If any line item is unclear, ask Hydro One to explain it in writing. Tocancel recommends keeping your final bill for at least 3 years in case you need to reference it for tax or dispute purposes.

Your cancellation checklist and next steps

Use this checklist to ensure you complete every step of the cancellation process and recover your full deposit.

Comparing your cancellation options and alternatives

While registered mail is the most secure method, you should understand your full range of options.

Registered mail is the clear winner because it provides legally defensible proof that you sent your cancellation request on a specific date. If Hydro One later claims they never received it, your return receipt proves otherwise. Tocancel advises against phone-only cancellations for utility accounts because call centre agents may not log your request properly, and there is no written record if a dispute arises later.

Your contact information and mailing address for Hydro One

To cancel your Hydro One account, send your registered letter to this address. Include your account number, full name, service address, and preferred cancellation date.

Hydro One Billing Department
P.O. Box 5700

For customer service inquiries or to confirm receipt of your cancellation request, you may also call Hydro One Customer Service at 1-888-664-9376. However, do not rely solely on a phone call; always send your cancellation request via registered mail to create a formal record.

When to escalate to the ontario energy board

If Hydro One refuses to cancel your account, denies your refund, or fails to process your request within 60 days, you have the right to file a complaint with the Ontario Energy Board at no cost.

Filing a complaint with the OEB

The Ontario Energy Board is the independent regulator responsible for protecting consumer rights in Ontario's electricity sector. You can file a complaint online at the OEB website (ontarioenergyboard.ca) or by mail. Your complaint should include your account number, a summary of the issue, copies of your cancellation letter and return receipt, Hydro One's responses (if any), and the resolution you are seeking. The OEB will investigate at no cost to you and issue a binding decision within 30 to 45 days. Tocancel has seen the OEB order refunds, account cancellations, and interest adjustments when utilities fail to follow proper procedures.
