Drivers lined up at the pumps in Toronto Tuesday evening in anticipation of a 3.4-cent gas price hike overnight.

The latest jump is part of a steady increase in gas prices over the week, with prices raising seven cents since Thursday.

Prices are expected to hit $1.36 per litre by midnight Wednesday.

At the Costco gas bar on Warden Avenue, near Ellesmere Road, lineups were at least 30 cars long, as drivers waited for their turn to fill up.

Speaking to CTV Toronto, gas price expert Dan McTeague said he couldn’t see a reason for the increase, other than a money grab.

The Associated Press, however, said an oil price hike comes ahead of a U.S. Federal Reserve meeting later in the week.

Drivers at the pumps were feeling the pinch.

“It’s pathetic, it’s absolutely pathetic,” said one Toronto driver. “And, you know what, we have to drive. We have to go to work. If they charge us $3, we’re still going to have to go to work.”

While Toronto drivers were complaining, Montreal residents had an even bigger shock as prices shot up to $1.53 per litre, a 15-cent jump from earlier Tuesday.
