Dispute Resolution Process 

Customer Service is an important part of the way Toronto Hydro-Electric System Limited does business. It's our goal to deliver superior service that meets your expectations on every phone call, email exchange, home or business visit.  Our Customer Service Representatives are trained to assist you with your inquiries and concerns.  If you have a concern or question, we encourage you to get in touch with us by telephone, email, mail or fax.

You may contact our Customer Care Department by telephone at 416.542.8000, Monday to Friday from 8 a.m.  8 p.m. ET or via our
CONTACT US online form. 

Please note that we are closed on all Statutory Holidays.

You may also send us a fax at 416.542.3429 or write us at:

Toronto Hydro
Attn: Customer Care
500 Commissioners Street
Toronto, ON M4M 3N7

It's our goal to ensure that our Customer Service Representatives have the answers you need on your first contact.  However, if you're not satisfied with the answers you have received, please review the following escalation process:


If you're not satisfied with the outcome of your initial contact with our Customer Care Department, you may request that your concern be escalated to a Supervisor.  If not immediately available, a Supervisor will contact you within two business days to work with you to resolve your concern.

Please Note: If your complaint requires further investigation, it will be referred to our Customer Management Service department. The Customer Management Service department will investigate your complaint and provide a response within two business days of receipt. If the investigation is expected to take longer, the Customer Management Service department will inform you within the two business day period and provide a date you can expect a response.

Most customer concerns are resolved before they reach this step; however, if you're still not satisfied with the outcome of your complaint after Step 1, please contact Customer Liaison, Office of the President.  The Office of the President reviews complaints only after they have been through Step 1. The Office of the President Customer Liaison will review the background of your complaint and work with the appropriate Toronto Hydro department to expedite a response typically within two business days.
