In the geopolitical chessboard of North America, a new tension is brewing as Canada contemplates a bold move in response to President-elect Donald Trump's proposed tariffs. The threat, issued by Ontario Premier Doug Ford, is not of military might or diplomatic sanctions, but of an energy embargo, a strategic withdrawal of a vital resource that binds the economies of the United States and Canada in a delicate embrace.

"We are prepared to take the drastic step of ceasing energy shipments to Michigan, New York State, and Wisconsin," warned Ford, his words echoing across the border with the weight of a gauntlet thrown. This is not merely a spat between neighbors; it is a potential economic siege, with the threat of cutting off the lifeblood of energy to regions that have long relied on Canada's generosity in the form of electricity and oil.

Ford's threat, though seemingly directed at the electricity that the U.S. imports from Canada, carries a deeper undercurrent. It is a shot across the bow, a warning that if Trump follows through with his promise of a 25% tariff on Canadian goods, Canada will not stand idly by. "While Canadians will suffer, I can assure you that Americans will also experience the repercussions, which is regrettable," Ford stated, his tone a somber acknowledgment of the mutually assured economic pain that could result.

The potential tariffs could precipitate a severe recession in Canada, a country whose economy is deeply intertwined with that of its southern neighbor. Ford's comments indicate a push within Canada for a robust response that might temporarily disrupt power and fuel supplies to some Americans, a move that would resonate far beyond the immediate impact on energy grids and gas prices.

The threat of a full-scale trade conflict between the U.S. and Canada looms like a dark cloud over the horizon, threatening to rain down economic hardship on both sides of the border. "This threat should not be dismissed. Canada is not willing to remain passive," said Patrick De Haan, GasBuddy's head of petroleum analysis, his words a clarion call to the seriousness of the situation.

Experts note that any Canadian retaliation, including from provinces, would require approval from the federal government in Ottawa. The U.S. regularly imports hydropower from Ontario, Quebec, and British Columbia, with Canada being the leading supplier of imported electricity to the U.S., albeit accounting for a relatively small portion of total consumption. Yet, this energy trade is crucial for grid balancing and bolstering electricity supply, especially during peak periods or when supply is weak.

The U.S. purchased approximately $3.2 billion of power from Canada last year, a decrease of nearly 30% from 2022. Power transmission lines connecting the U.S. and Canada are part of a complex and highly interconnected power system, with connections stretching from New England to the Pacific Northwest. A sudden change in this close relationship could cause difficulties for U.S. states bordering Canada that sometimes rely on electricity imports.

However, these issues would likely be temporary, according to RJ Johnston, research director at Columbia University's Center on Global Energy Policy. "I don't see significant vulnerability for the U.S.," Johnston said, pointing to the U.S.'s abundant electricity resources and the option to redirect power to areas in need. "Even in the event of an extended outage, the U.S. has the capacity to increase generation capacity in a relatively short period," Johnston said.

Instead of electricity, Johnston suggested that Canada could have more influence over the U.S. in areas that are more challenging for U.S. officials to compensate for, such as aluminum and nickel. Canada is also the top source of foreign oil for the U.S., with the U.S. importing 1.4 million barrels of Canadian crude daily, constituting over half of the total 2.4 million barrels of U.S. oil imports.

De Haan, the GasBuddy analyst, cautioned that some refineries in the Midwest and Great Lakes regions depend on Canadian crude to produce gasoline, diesel, and jet fuel. He said the loss of Canadian oil could temporarily increase prices and make it difficult for some gas stations to secure fuel. "I would be more concerned about supply than price," he said.

However, analysts are skeptical that Canada would use this tactic in a trade war because its economy heavily relies on oil production and the U.S. as a buyer of that crude. Blocking the flow of oil to its largest customer—the U.S.—would be detrimental to Canada's own economy. "Do I think that would ever happen? No, because it would affect everyone involved," said Robert Yawger, vice president of energy futures at Mizuho Securities.

Nevertheless, the opening of the Trans Mountain Pipeline from Alberta to the Pacific Ocean does leave open the possibility that Canada could eventually sell significant amounts of oil to Japan, South Korea, China, and other Asian nations. "That's why they built that pipeline: To have a plan B," said Yawger.

It is unclear how much the U.S. would be affected by the loss of Canadian oil. U.S. oil production has surged over the past two decades due to the shale revolution. Domestic oil output is so high that the U.S. is now a leading exporter of oil. Analysts say that some of the oil currently shipped overseas could be redirected to stay in the U.S. if there was a loss of Canadian barrels.

While Ontario's premier has proposed cutting off electricity exports to the U.S., it is uncertain whether the major oil-producing provinces would be willing to do the same regarding the crucial resource of oil. "Wake me up when the mayor of Calgary or the premier of Alberta starts making threats like this," said Yawger.

Danielle Smith, the premier of Alberta, made it clear on Thursday that there is little appetite for such a move, stating that she prefers a diplomatic approach. "Under no circumstances will Alberta agree to cease oil and gas exports," Smith said.

In this delicate dance of economic interdependence, both the U.S. and Canada must tread carefully. The threat of energy embargoes and trade wars looms large, a reminder that in the complex web of global trade, there are no clear winners, only the potential for shared pain and the hope for mutual understanding and cooperation. The future of this relationship hangs in the balance, a testament to the fragility of economic partnerships and the need for diplomacy in times of uncertainty.
