What is electricity?
Electricity is the flow of electrons from a negatively charged body to a positively charged body. Electricity is a secondary energy source with a large number of applications that include heating, lighting, and powering electric motors.
- 67% of Canada’s electricity comes from renewable sources and 82% from non-GHG emitting sources
- Canada is the world’s second largest producer of hydroelectricity
- Canada exports nearly 9% of the electricity it generates to the United States. There are 34 active major international transmission lines connecting Canada to the U.S.

The electricity industry performs three main activities:
- Generating electricity by using various energy sources and technologies
- High-voltage transmission of electricity, usually over long distances, from power plants to end-use markets
- Distributing electricity to end-users, usually through low-voltage, local power distribution lines
In some provinces, electricity is provided by vertically integrated electric utilities that are often structured as provincial Crown corporations. Vertically integrated electric utilities dominate every part of the supply chain and are the primary Generator, Retailer and System Operator in the electricity market.

In 2018, Canada exported 61.4 TWh of electricity to the U.S and imported 13.2 TWh.
Exports of electricity under purchased contracts, excluding electricity transferred under non-financial agreements, such as treaty obligations, have been generally increasing since 2010 whereas imports have been declining. In 2018, Canadian exports were 61 terawatt hours and imports were 13 terawatt hours.
Since the means of producing electricity as well as the infrastructure to get it to its users varies across provinces, so do the prices of electricity for Canadian residents and industries.
Average residential and large industrial electricity prices, including taxes, for one city per province in cents per kilowatt-hour for April 2018.
|City||Industrial Price (cents/kWh)||Residential Price (cents/kWh)|
The total electricity energy use in Canada in 2016 was 1,785 petajoules (PJ). The residential, commercial, industrial, transportation and agricultural sectors all share in the intensive demand for Canadian electricity.

*Secondary energy use
Electricity energy use varies greatly from province to province. Provinces with plentiful and cheap electricity from large scale electricity projects like British Columbia and Quebec, tend to use more electricity per person than those provinces who rely on other energy means to do things like heat their homes and water.
Total electricity energy use in Canada in 2016 was 1,785 petajoules. Québec has the largest share of consumption at 35%, followed by Ontario at 27%, Alberta at 11%, British Columbia and the Territories at 12%, the Atlantic provinces at 7%, Saskatchewan and Manitoba both at 4%.
