As of August 26, 2026, the escalating US-Canada trade dispute is threatening to disrupt electricity trade between the two countries and could raise power prices in parts of the US. [1] Canada is expected to announce retaliatory tariffs on US goods after President Donald Trump’s 50% tariffs on about $20 billion ($27.6 billion CAD) of Canadian goods took effect. [2] Ontario Premier Doug Ford and Canadian Prime Minister Mark Carney have discussed a potential 25% tariff on electricity exports to the US, while Ontario has also considered restricting electricity exports in response. In 2025, Canada exported 32.7 TWh of electricity to the U.S., compared with 22.1 TWh of imports from the US, underscoring the importance of the cross-border relationship. While grid operators do not expect reduced Canadian imports to cause major reliability problems under normal conditions, losing Canadian power could increase reliance on more expensive generation and put upward pressure on electricity prices, particularly during periods of extreme weather.
