There’s a prediction that gas prices will be on the rise again tomorrow.

The Consumer Group for Fair Gas Prices expects that it will cost an extra 2.3 cents a litre to pump gas in the tank come midnight tonight.

Gas guru George Murphy is also predicting an increase in heating, stove oil and diesel of 1.8 cents per litre.

The US summer driving season is in full swing with consumers south of the border taking to the roads in droves, creating higher demand for gasoline.
