Expect to see gas prices increase.
Producers will be switching over from winter blends to summer blends in the next 10 days.The annual switch usually means about a four cent a litre increase at the pumps.
Summer blends have different components than winter blends and are more expensive to produce.
"So there's a real changeover that takes place. And there is a real cost impact for refiners which they pass onto motorists," said Dan McTeague, a petroleum analyst with Gas Buddy.
Area prices right now are about 13-15 cents a liter higher than this time last year. That number could widen with the nationally mandated transition to the summer blends.
McTeague predicts summer prices will remain high.
"We could see prices perhaps scratching $1.30 at sometimes, but I think this is probably as high as it's going to get at least between now and the May 24 weekend. After that, it's anyone's guess."
Other factors McTeague says affect gas prices include the carbon tax and a weaker Canadian dollar.
