Market Snapshot: Canada’s nuclear energy output ranked 6th in the world

Release date: 2017-06-07

In 2016, Canada produced 3.9% of the world’s total nuclear energy output. This ranked Canada 6th in the world behind the United States, France, China, Russia, and South Korea. The vast majority of Canadian nuclear energy is produced in Ontario, which alone accounted for more than 3.7% of global nuclear output and ranked higher than entire countries such as Germany and the United Kingdom.

Description: This bar chart shows the percentage output of the world’s top ten nuclear generating countries from highest to lowest. The top 10 countries are: USA (32.5% share), France (15.6%), China (8.0%), Russia (7.4%), South Korea (6.2%), Canada (3.9%), Germany (3.2%), Ukraine (3.1%), UK (2.6%) and Sweden (2.4%). The bar for Canada is split to show how much output came from Ontario and New Brunswick, respectively. Ontario contributed 3.7% of global output, while New Brunswick contributed 0.2%.

Nuclear is Ontario’s primary source of electricity. Currently, 56% of Ontario’s electricity generation is sourced from Ontario’s nuclear facilities, which are home to three of Canada’s four nuclear power plants and 18 of Canada’s 19 commercial nuclear reactors. Bruce Power’s 6400-megawatt facility in Kincardine, Ontario, is the largest operating facility in the world and has a total generating capacity greater than India’s 22 nuclear power reactors combined.

Due to this large base in Ontario, nuclear power currently comprises 15% of Canada’s total electricity generation. The only other Canadian nuclear plant and commercial power reactor outside of Ontario is New Brunswick’s Point Lepreau Generating Station. Quebec’s Gentilly-2 nuclear facility was shut down in 2012 in the face of high refurbishment costs, and there are currently no new nuclear energy projects underway in CanadaFootnote 1. As other types of energy gain capacity and nuclear capacity remains relatively constant, nuclear power’s share of Canadian electricity generation is expected to fall in the coming decades.
