Canada Was a Net Electricity Importer for Three Consecutive Months. December 2025 Imports from the US Rose 79% Year-Over-Year.

Statistics Canada's March 2026 release of December 2025 energy statistics confirmed that Canada was a net electricity importer for three consecutive months — October, November, and December 2025. Imports from the United States in December reached 3.1 million MWh, up 79.3% versus December 2024, against exports of 2.3 million MWh, down 34.5%. The same three-month pattern occurred earlier in 2024 (March 2024 alone reached 3.3 million MWh in imports, the highest single month in the series). Drivers are provincial and physical: drought-reduced hydroelectric output in British Columbia and Quebec, paired with scheduled nuclear-plant refurbishments in Ontario that pushed Ontario's combustible-fuel generation up 56.8% to 4.2 million MWh. British Columbia accounts for roughly 57% of Canadian electricity imports from the United States. Electricity generation, transmission, and trade are constitutionally provincial jurisdiction; the federal government regulates the international crossing only.
