Gas prices in Ontario jump 10-cents per litre overnight

Drivers in Eastern Canada are going through sticker shock at the pumps, as prices jumped roughly 10-cents per litre overnight in regions such as Ontario, according to GasBuddy.Patrick De Haan, head of petroleum analysis at GasBuddy, says gasoline price increases during the spring season are quite normal as refineries switch their supply from winter to summer gas.Winter gas is cheaper than summer blends because it contains higher butane levels – an inexpensive but volatile element which lowers the cost of fuel, he adds.
