The
North American Ice Storm of 1998 (also known as
Great Ice Storm of 1998) was a massive combination of five smaller successive
ice storms which combined to strike a relatively narrow swath of land from
eastern Ontario to southern
Quebec to
Nova Scotia in Canada, and bordering areas from northern
New York to central
Maine in the United States, in January 1998. It caused massive damage to trees and electrical infrastructure all over the area, leading to widespread long-term power outages. Millions were left in the dark for periods varying from days to weeks, and in some instances, months. It led to 35 fatalities, a shutdown of activities in large cities like
Montreal and
Ottawa, and an unprecedented effort in reconstruction of the power grid. The ice storm led to the largest deployment of Canadian military personnel since the Korean War, with over 16,000
Canadian Forces personnel deployed, 12,000 in Quebec and 4,000 in Ontario at the height of the crisis.
