Canada is the largest foreign supplier of crude oil to the U.S., exporting over 3.7 million barrels per day, which is more than half of total U.S. oil imports. If that supply suddenly disappeared, it wouldn’t just be a problem for North America; the implications of this would be prominent throughout the global energy market.
Rising fuel prices, supply shortages, and shifts in trade relationships could force governments and businesses to rethink their energy strategies. Although it seems unlikely, growing political tensions, environmental policies, and new trade priorities could push Canada to reconsider where its energy goes. If that happens, we will see the impacts worldwide.
Canada is one of the world’s largest energy producers, ranking among the top five global oil suppliers. A massive portion of its crude oil, natural gas, and refined petroleum products are exported, with the U.S. as its primary customer. In 2023, Canada sent over 3.7 million barrels of crude oil every day to the U.S., making up more than half of total U.S. crude imports. This trade relationship is built on an extensive pipeline network, including Keystone XL, Enbridge Line 5, and the Trans Mountain Pipeline, which ensures a steady flow of Canadian oil to U.S. refineries.
Canada is also a major exporter of natural gas and electricity, particularly to states like Michigan, New York, and California. The U.S. and Canada are interlinked in energy trade, and any disruption can seriously affect both economies. With energy security becoming a growing concern, the possibility of Canada cutting or shifting its exports raises concerns about how the energy market will change.
While a full halt on Canadian energy exports isn’t likely, there are a few reasons why Canada might consider limiting or shifting where its energy goes. One of the biggest factors is environmental and climate policies. Canada has set net-zero emissions goals by 2050, which means ramping up investment in renewable energy and cutting back on fossil fuel reliance. Stricter regulations on oil production or the gradual phaseout of pipelines could naturally lead to a drop in exports.
Trade tensions with the U.S. could also play a role. Disputes over pipelines, tariffs, and energy regulations have caused issues between the two countries before, and if new restrictions are implemented, Canada could start looking into other regions. China, India, and Europe are all growing energy markets that could become priority buyers. Canada also might want to diversify its energy partnerships to avoid relying too heavily on U.S. demand. As the global energy market changes, Canada could focus its exports on regions offering better long-term trade relationships.
If Canada were to cut its energy exports, the U.S. would feel the impact immediately. A sudden drop in Canadian oil supply would drive up gasoline and diesel prices, hitting both consumers and businesses across multiple industries. To offset this, the U.S. would have to ramp up domestic production or turn to alternative suppliers like OPEC, Venezuela, or other oil-producing nations. Beyond price hikes, U.S. refineries would have to make adjustments. Many are designed specifically for Canadian heavy crude, so losing that supply would mean expensive modifications and potential reductions in overall fuel output.
Natural gas and electricity exports from Canada are also a key part of the energy trade between the two countries. Regional power grids in northern U.S. states, especially those that rely on Canadian hydroelectricity, would be negatively impacted.
