Ontario drivers are set to receive an unexpected break at the pumps just ahead of the busy U.S. Memorial Day long weekend, despite ongoing tensions in the Middle East and growing concerns over global oil supplies that would normally push fuel prices higher.
According to Dan McTeague, gasoline prices across Ontario are expected to remain unchanged on Thursday before dropping by nine cents per litre on Friday. Diesel prices, meanwhile, are forecast to rise by four cents per litre on Thursday before falling sharply by nine cents on Friday.
The surprising decline comes at a time when many analysts expected the exact opposite. Rising summer travel demand in the United States, shrinking American crude oil reserves, and continuing instability in the Middle East have all traditionally been indicators of higher fuel prices. Yet global oil markets moved lower on Wednesday, leaving industry experts puzzled.
McTeague described the current market movement as being completely out of sync with normal economic fundamentals. He noted that in more than three decades of forecasting fuel prices, he has rarely witnessed such a dramatic contradiction between supply-demand realities and actual market behaviour.
Recent data released by the U.S. Energy Information Administration showed a significant decline in American crude oil inventories, while millions of Americans are preparing to hit the roads for the unofficial start of summer during the Memorial Day weekend. At the same time, uncertainty continues to surround the conflict involving Iran, Israel, and the United States.
Although U.S. President Donald Trump has repeatedly suggested that negotiations are moving closer to a resolution, investors remain cautious as no permanent breakthrough has yet been achieved.
McTeague believes speculative trading and market manipulation may be contributing to the unusual drop in prices. He warned that while motorists may welcome short-term savings now, the longer-term impact could result in much higher fuel costs in the months ahead as markets eventually correct themselves.
Fuel prices in Canada have been climbing since military tensions escalated earlier this year following attacks involving Iran, the United States, and Israel. One of the major concerns has been instability around the Strait of Hormuz — a critical global shipping route through which roughly one-quarter of the world’s seaborne oil passes.
Any disruption in that region immediately affects international energy markets, including prices paid by Canadian consumers at local gas stations.
For drivers looking to save additional money at the pumps, McTeague recommends filling up in the evening, particularly after 6 p.m. in the Greater Toronto Area, when stations often lower their profit margins to remain competitive. He also noted that gas prices are usually cheaper outside major urban centres, making it worthwhile for travelers to fuel up before heading into the city.
