The price of gas shot up overnight.

With prices in Ottawa surpassing $1.20 per litre, prices in west Quebec are also up by about two cents.

The cost to fill up your tank was cheaper at one gas station near Richmond Road and Churchill Friday morning. According to ottawagasprices.com, that gas station was still selling gas for $1.11 per litre.

Liberal MP Dan McTeague predicted the price change on Thursday and is accusing refiners of taking advantage of consumers.

McTeague told The Canadian Press that market fundamentals do not support the rising prices.

"There is no rhyme or reason for what is driving this price. We have to finger the refinery, the oil industry, the major four oil companies in Eastern Canada, who are producing the product and who are simply taking advantage of a very, very difficult situation, no doubt compounding problems for the economy,'' he said.

Still, Edward Jones analyst Lanny Pendill said Thursday that pump prices have not even come close to catching up with refiners' soaring costs.

"The net impact has been the profitability at the refineries has declined significantly from last year's levels,'' he said.

"The refiner, in essence, is absorbing some of that cost increase of oil.''

BNN's Linda Sims reported an ease in crude oil prices Friday. Still, she said prices remained above US$114 a barrel. Oil prices hit an all-time high above US$115 a barrel on Thursday.
