REGINA, Sask. — Gas prices in Regina jumped more than 20 cents a litre over the past week, with the average price reaching 176.87 cents per litre on Sept. 13, according to GasBuddy.
GasBuddy's daily survey of 82 gas stations in Regina found average retail gasoline prices increased 20.1 cents per litre over the past week.
The national average increased 3.3 cents per litre during the same period to 179.10 cents per litre.

GasBuddy historical data shows Regina gas prices on Sept. 14 have varied considerably over the past five years.
The average was 137.65 cents per litre in 2025, 147.08 cents per litre in 2024, 162.15 cents per litre in 2023, 150.91 cents per litre in 2022 and 130.74 cents per litre in 2021.
Prices have also risen sharply in nearby markets.
Saskatoon averaged 176.28 cents per litre, up 20.6 cents from 155.68 cents per litre a week earlier.
The Saskatchewan average stood at 171.43 cents per litre, up 11.8 cents from 159.65 cents per litre the previous week.
"Average gasoline and diesel prices rose across every province over the last week as geopolitical tensions escalated on multiple fronts, with friction between the U.S. and Iran, new hostilities in the Red Sea, and the shutdown of Saudi Arabia's East-West pipeline all combining to jolt prices sharply higher," said Patrick De Haan, head of petroleum analysis at GasBuddy.
"Canada's national average diesel price hit a new all-time record, crossing 250 cents per litre as of Sunday night according to GasBuddy, as new weekend attacks knocked two additional Russian refineries offline and further strained global refined product supplies. While the transition to winter-blend gasoline may offer some modest relief at the gas pump in the weeks ahead, the scale of ongoing geopolitical escalations makes meaningful price relief for diesel unlikely in the near term. Canadians should brace for continued volatility ahead."
