Canada Threatens to Cut Uranium and Power Supplies to US Amid Trade Tensions

Key Facts

1Ontario Premier Doug Ford stated Canada should be ready to cut off U.S. access to electricity and critical minerals, including uranium.

2Cameco owns 100% of the Blind River refinery in Ontario, which is the world's largest commercial uranium refinery.

Amid escalating rhetoric regarding critical mineral security and energy interdependence, new tensions have emerged between Canada and the United States. According to reports, Ontario Premier Doug Ford stated that Canada should be prepared to cut off U.S. access to electricity and strategic minerals, including uranium. These comments place the Blind River refinery in Ontario, 100% owned by Cameco, at the center of potential trade friction as it remains the world's largest commercial uranium refinery.

These threats arrive during a period of structural deficit in the global uranium market, which supports a bullish outlook for prices and sector-linked equities. Cameco (CCJ) is a pivotal player in this landscape due to its control over strategic refining assets. Per market data, CCJ shares closed at $107.84 on August 26, 2026, after reaching a day high of $111.54, while 0R35.L stood at 141.63 as of the August 24, 2026 close.

Traders should watch CCJ support levels near the recent low of $106.91 (close August 26, 2026) to gauge market reaction to these geopolitical pressures. Looking at the economic calendar, there are no immediate upcoming catalysts specifically for the Canadian energy sector in the next seven days, but continued political rhetoric may drive volatility in uranium spot prices and related mining stocks.
