Oil Supply Crunch Hits North America: Canadians Brace for Steeper Gas and Grocery Bills

Economists are warning Ottawa residents to prepare for higher costs at the pump and the grocery store as crude oil prices surge due to a major supply contraction—a trend that could signal broader inflationary pressures across North America.

Gasoline prices in Ottawa have already climbed steadily in recent months, reaching a high of $1.54 CAD per liter on March 2, 2026, up from $1.40 in late December 2025. The volatility reflects mounting pressure on global oil markets that economists say will soon ripple through the broader economy.

“There’s been a major contraction in the supply of crude oil. Crude oil is a major input in the production of jet fuel and gasoline, and so the prices of any product that uses crude oil as an input is going to rise.”

— Gray, Economist

The spike isn’t confined to Ontario. Across Canada’s Maritime provinces, consumers saw a third round of price increases on March 6, with Nova Scotia gas hitting a minimum of $1.50 CAD per liter, Prince Edward Island reaching $1.60, and New Brunswick climbing to $1.50. The London, Ontario region also reported pump prices of $1.44 per liter on March 4.

But economists Gray and Bernard warn that rising fuel costs won’t stop at gasoline stations. The impact is expected to cascade through the entire supply chain, affecting everything from produce aisles to online shopping deliveries.

Grocery prices are particularly vulnerable because Canada relies heavily on imported fruits, vegetables, and grains from California, Florida, and Mexico. Those imports require trucking or air freight—both of which depend on fossil fuels. Even domestically produced meat, produce, and grains must be transported across Canada’s vast geography to reach supermarket shelves.

For American consumers, Canada’s experience serves as a potential preview of what could unfold in U.S. markets. The interconnected nature of North American supply chains means transportation cost increases in Canada often mirror or foreshadow similar pressures stateside, particularly for regions that share cross-border trade corridors.

The effects also extend to consumer goods beyond food. Miscellaneous retail purchases—including Amazon deliveries and clothing from shopping malls—will likely see price adjustments as retailers pass along higher logistics costs to customers.

With the average Ottawa gasoline price hovering around $1.45 CAD per liter over the past three months, consumers are already feeling the pinch. Economists suggest budget-conscious households may need to prepare for sustained higher prices across multiple spending categories if the crude oil supply situation doesn’t improve.

The broader implications for inflation-wary central bankers on both sides of the border remain to be seen, but the supply-driven nature of these price increases presents a familiar challenge: how to contain cost-of-living pressures when the root cause lies beyond domestic policy control.
