The price of gasoline in Southern Ontario is set to rise to its highest level since last fall tomorrow, Wednesday.

Drivers in the Greater Toronto Area should expect nearly a 10-cent increase at the pumps when they fill up tomorrow, according to Dan McTeague, president of Canadians for Affordable Energy.

Prices in the GTA and much of Southern Ontario have been hovering around 156.5 cents per liter, but will jump to 164.9 overnight — a figure unseen since November 15.

Also, according to McTeague, prices could rise further in the coming months. He told CTV News Toronto: "Sooner or later, markets will have to realize that the fundamentals support higher prices, not lower prices. This is really just the beginning of what could be a bit of a gas price or energy price cycle that could push us back — not what we saw last year when it hit 215.9 on June 8 here in the GTA and across much of Ontario — but more consistently."

McTeague also added that he will be closely watching south of the border to see if their federal government decides to halt raising interest rates, which would have a direct effect on pump prices.

The next Federal Reserve interest rate announcement is scheduled for May 3.

Until then, and as Ontarians look for solutions, there is one way to save on gasoline according to McTeague: buying outside the city.
