Canada is divided into ten provinces and three territories. The majority of Canada's population is concentrated in the areas close to the Canada -- US border. Its four largest provinces by area (Quebec, Ontario, British Columbia and Alberta) are also (with Quebec and Ontario switched in order) its most populous; together they account for 86% of the country's population. The territories (the Northwest Territories, Nunavut and Yukon) account for over a third of Canada's area but are home to only 0.3% of its population, which skews the national population density value.

The disaster began during a systems test on 26 April 1986 at reactor 4 of the Chernobyl plant near Pripyat and in proximity to the administrative border with Belarus and the Dnieper River. There was a sudden and unexpected power surge. When an emergency shutdown was attempted, a much larger spike in power output occurred. The second spike led to a reactor vessel rupture and a series of steam explosions. These events exposed the graphite moderator of the reactor to air, causing it to ignite. The resulting fire sent week long plumes of highly radioactive fallout into the atmosphere over an extensive geographical area, including Pripyat. The plumes drifted over large parts of the western Soviet Union and Europe. According to official post-Soviet data, about 60% of the fallout landed in Belarus.
