Gas prices jump 8 cents Wednesday, biggest spike since May

Ottawa drivers will pay 177.9 cents per litre for gas starting Wednesday — an eight-cent jump that marks the largest single-day increase since early May. The spike reverses a week of steady declines that had brought relief at the pumps after prices climbed earlier in the month. Analysts say volatility is likely to continue through June as summer travel ramps up and global markets react to shifting supply signals. The eight-cent surge pushes prices back near levels seen in early May, when the region briefly approached the 180-cent mark.
