Using oil to retaliate against U.S. would be exceedingly stupid

By the Editorial Team · Friday, August 28, 2026

Canadian political leaders have proposed using the country’s energy exports as leverage in response to stalled trade talks with the U.S., though government officials and experts warn this could harm both economies and disrupt critical supply chains. Given Canada’s heavy reliance on U.S. pipelines and the high costs of alternative transport or new markets, such measures risk reducing oil output, damaging domestic economies, and prompting the U.S. to seek other suppliers long-term.

In the wake of recent trade negotiations between Canada and the United States breaking down, some Canadian political figures have floated the idea of leveraging the country’s energy resources as a means of economic retaliation against the U.S. Prominent voices advocating for this approach include Ontario Premier Doug Ford and former Alberta Premier Jason Kenney. Notably, NDP Leader Avi Lewis also expressed support, while his party successor Danielle Smith and Saskatchewan Premier Scott Moe have cautioned against such measures.

Prime Minister Mark Carney has stopped short of endorsing the concept of using energy as a weapon, but he acknowledged Canada’s significant role in fueling U.S. economic growth. This acknowledgement suggests the idea remains under governmental consideration.

Experts and policymakers alike warn that restricting Canada’s energy exports to the U.S. would be a profoundly unwise move. Canada currently sends approximately 85 percent of its oil production south of the border, predominantly through pipeline networks designed specifically for this trade. The absence of excess pipeline capacity to reroute exports to other international markets means any attempt to curtail shipments would likely force Canadian producers to reduce output. This would have severe implications for the domestic economy, particularly in Alberta, where oil extraction makes up about 20 percent of the province’s GDP.

Some have proposed an export tax as a less harmful alternative that would increase costs for U.S. buyers without drastically reducing oil volumes. However, this too carries significant risks. The U.S. could respond by limiting flows of refined products from its refineries, which themselves depend heavily on Canadian oil supplied via American-operated pipeline infrastructure. Ontario’s refineries, for example, rely predominantly on Canadian crude delivered through U.S. pipelines, while half of Quebec’s refined oil supply originates from American sources. Any Canadian export restrictions or tariffs would thus disrupt energy supplies within these regions, potentially triggering economic downturns.

Attempting to move crude oil via rail to circumvent U.S. pipelines poses additional challenges. Rail transport is more expensive, less efficient, and could strain Canada’s rail network, which is critical to various industries beyond energy.

Long-term consequences also loom large. Increased Canadian energy costs prompted by tariffs or export limits would incentivize the U.S. to seek alternative suppliers. While such a transition would not be immediate, once established, these new supply chains could become permanent, reducing future Canadian market access. Developing new export routes and customers for Canada’s roughly 4.5 million barrels per day of oil exports would require substantial infrastructure investment and years to complete. For context, a proposed West Coast pipeline expected to carry around one million barrels daily would cost nearly $40 billion, indicating the scale of the challenge.

Smith and Moe have underscored that weaponizing Canadian energy would inflict damage on both the Canadian and U.S. economies over the short and long term. Many analysts suggest that the current trade conflict represents a temporary setback and caution that retaliatory measures could undermine Canada’s own economic interests. Instead, they advocate focusing on strengthening Canada’s economy and competitiveness rather than engaging in actions that might exacerbate tensions and economic harm.

As one expert put it, sometimes the most effective response to external pressure is not direct confrontation but rather resilience and self-improvement.
