Drivers across Durham Region and Ontario are seeing fuel prices climb again after a brief drop earlier this week.
According to GasWizard.ca, the latest Ontario gas prices May 2026 increased by approximately three cents per litre over the weekend, pushing regular gasoline prices to around 183.9 cents per litre across much of southern Ontario.
The increase follows several days of lower fuel prices earlier in the week when motorists briefly saw some relief at the pumps.
Premium gasoline prices have also risen, climbing three cents to approximately 213.9 cents per litre, while diesel fuel increased by two cents to around 202.9 cents per litre.
Industry reports suggest the current Ontario gas prices May 2026 could remain relatively stable through at least May 27 unless major market changes occur.
Earlier this week, fuel analysts reported that gas prices across southern Ontario had dropped significantly for a short period. On May 22, fuel market tracking from En-Pro indicated regular gasoline prices had fallen by eight cents, with an additional four-cent decrease expected the following day.
Those temporary declines brought average prices across much of the Greater Toronto Area and southern Ontario closer to 179.9 cents per litre before prices began climbing again over the weekend.
Despite the recent fluctuations, fuel costs remain lower than the sharp spike experienced earlier this month.
On May 6, regular fuel prices across southern Ontario surged by approximately seven cents in a single day, reaching nearly 195.9 cents per litre in many communities including Durham Region and the GTA.
At the same time, premium fuel prices climbed to approximately 225.9 cents per litre.
Fuel market experts say several international and economic factors continue influencing the changing Ontario gas prices May 2026.
Dan McTeague, president of Canadians for Affordable Energy, previously stated that lower global oil prices could eventually provide some relief for consumers. However, he also warned that fuel prices may remain elevated due to ongoing concerns surrounding oil supply stability and international market uncertainty.
Analysts say gasoline prices are currently being affected by multiple global factors including refinery production levels, international conflicts impacting oil supplies, seasonal fuel demand, and broader commodity market fluctuations.
Spring and summer months often bring increased gasoline demand across Ontario as travel activity rises and more residents take road trips throughout the province.
Drivers across Durham Region, Toronto, Hamilton, Mississauga, Niagara, Halton, and other Ontario communities continue monitoring daily fuel changes as prices remain unpredictable from week to week.
Financial experts recommend motorists compare fuel prices locally, limit unnecessary travel where possible, and monitor market updates during periods of significant volatility.
As global oil markets continue responding to geopolitical developments and changing supply conditions, Ontario residents are expected to see continued fluctuations in fuel costs throughout the coming weeks.
