Electricity meters are installed by Toronto Hydro-Electric System to measure electrical usage. Electricity use is measured in kiloWatt-hours (kWh). One kWh is the amount of electricity 10 100-Watt bulbs will use in one hour.



Meter Performance

All electricity meters used by Toronto Hydro-Electric System bear a seal from the Legal Metrology Branch of Industry Canada (Measurement Canada). The seal indicates that your meter, or a meter manufactured in the same group, has been tested for performance, reliability and accuracy before installation.

Hydro Owned

Your electricity meter is owned, installed and maintained by Toronto Hydro-Electric System. It is an offence to tamper with an electricity meter.

Meter Checks

Toronto Hydro-Electric System technicians have extensive training in operation of meters and can perform an accuracy test on site.

Industry Canada also carries out random checks of installed meters. If a meter fails such a test, all meters manufactured in that group will be removed and individually tested.
