Metering Specifications

The safety and reliability of your electricity is our main priority.  We have guidelines and requirements for metering equipment that must be followed before we will energize your project. Customers and their electricians or contractors are responsible for understanding these requirements and following them prior to having their project energized.

We have the right to refuse to energize any part of a project that does not follow these requirements. When you do not follow the requirements, we are not responsible for the cost of repairs, or delays in energizing the system. Please refer to the Meter Specifications document for more information on metering requirements.

Conditions of Service

Every Electricity Distribution Company in Ontario must have a Conditions of Service document . The purpose of this document is to provide information on the types and level of service available to customers. The Conditions of Service contains all the information you need whether you're building a home or office or simply adding to an existing structure.

Suite Metering

Are you developing a multi-unit building or condominium? Is so, we recommend you consider utility suite metering. 

Utility Suite Metering is a simple, cost effective program offered to condominium and rental buildings, where each unit gets its own meter.  This means that customers pay only for the electricity used in their unit and can benefit from their individual conservation efforts.
