Prime Minister Mark Carney announced a national electricity strategy in May, amid worsening trade tensions with Washington. The strategy aims to double Canada's grid by 2050 to accommodate projected growth in electricity demand, with priority given to east-west connections. The government identified five priority transmission connections between provinces in June. Canada's east-west transmission projects remain in planning. Carney and the provincial premiers agreed in July to complete pre-development by July 2027 and begin the first projects by the end of 2027.
Trade negotiations broke down in August. The United States imposed a 50% tariff covering about $20 billion of goods from Canada, with energy excluded. Ontario Premier Doug Ford said days later that Ontario would halt electricity exports to New York, Michigan and Minnesota if the dispute worsened. Canadian officials present the grid initiative as supporting affordability and reliability, while also describing the initiative as a national security issue.
Dozens of electricity lines connect Canada and the United States, and Canada's provinces have exported electricity south for more than a century. Each province manages a separate grid. Exporting south was easier and more profitable because of demand from the United States, whose population is almost ten times Canada's population. Transmission capacity between Canada and the United States totals roughly 28 gigawatts. Connections between Canada's provinces total only about 17 gigawatts.
North America's electricity network comprises four systems: the Eastern and Western Interconnections, both crossing the international border, ERCOT in Texas, and Quebec's grid. Ontario and New York power plants operate together within a synchronized system. British Columbia and Washington state likewise operate within a synchronized system. Both countries use reliability standards established by the North American Electric Reliability Corporation.
Additional east-west connections should improve Canada's grid reliability and would give Canada the option to retain electricity domestically. However, reduced integration would weaken reliability in both countries, with unequal effects. Canada's electricity supplies are critical to the US Northwest during periods when available power is tightest. Transmission from Ontario and Quebec can supply about 4,600 megawatts, equivalent to roughly 15% of New York's peak summer demand. Imports from Canada supplied 9% of New York's demand during a July 3 heat wave. A recent Cornell study found that imports from Canada supplied about 45% of New York's demand during some five-minute intervals.
Electricity supply must match demand every second. Losing such a large supply during a stressed period can activate protective systems and cause cascading regional disruptions. Dependence also extends northward. The Canada Energy Regulator said British Columbia's net electricity imports from the United States equaled 18% of British Columbia's generation in 2023, when reservoirs were low.
Canada generally produces more electricity than Canada consumes, making connections between provinces the principal gap if the countries' grids separate. However, the US Northeast would require additional generation. New York's grid operator warned this year that existing plants are retiring faster than replacement supplies become available. Hydropower supplies more than half of Canada's electricity and faces increasing disruption from drought. Large reservoirs help protect supply during dry years. The Canadian Climate Institute projects that climate change will increase drought risk across much of central Canada, potentially making dependence on hydropower a long-term liability.
Canada can distribute abundant energy resources across a population much smaller than the US population. New east-west connections could let provinces with surplus hydropower support neighboring provinces during droughts rather than requiring imports from the United States. However, the United States faces tighter supply conditions. The North American Electric Reliability Corporation warned in January that new supply will lag rapidly growing demand from electrification and data centers. The next few years will determine whether the countries preserve an integrated system or gradually separate, with the higher-demand United States potentially experiencing the effects first.
Canada Expands Grid Strategy Amid Trade Tensions with U.S.

Summary
Canada unveiled a spot grid strategy in May to double its electricity capacity by 2050, focusing on east-west links. The futures grid strategy aims to boost reliability and affordability while managing security risks amid U.S. trade disputes. The U.S. hit $20 billion of Canadian goods with a 50% tariff in August, excluding energy. Ontario’s leader warned of halting U.S. electricity exports if tensions rise. Current exports to the U.S. remain steady, but domestic connections are weak. A Cornell study found Canadian power covers up to 45% of New York’s peak demand. Hydropower, a key source, faces climate and drought threats. The next few years will decide if the two countries maintain an integrated grid or drift apart.
