Customer Service is an important part of the way we do business. It's our aim to meet and exceed your expectations on every phone call or at every home or business visit.

Important: Toronto Hydro is warning its customers of a telephone scam from people claiming to be from our collection and billing department.

The calls are being made from a 1-800 number and customers are being threatened with a disconnection of electricity if they do not immediately provide payment in the form of a pre-paid debit card or wire transfer. Toronto Hydro does not ask for a pre-paid credit card payment or wire transfer in overdue account situations, nor does our Customer Care department have a 1-800 number.

Report any suspicious calls to Canadian Anti-Fraud Centre immediately, at 1-888-495-8501 and quote file number 844396.
