Gas prices in the greater Montreal region are now hovering around $1.17 a litre.
"We were expecting that there was going to be an increase because we know that when the retail margins are really small in Montreal [a low price] doesn't last very long — but this time, for us, the spike in the price is way too high," said CAA-Québec spokeswoman Anne-Sophie Hamel.
She said Montrealers pay the highest sales taxes on gas in North America — about 36 per cent. Drivers here also pay a three-cent-a-litre carbon tax.
CAA-Québec recently released its report into 2014 gas prices.
Hamel said that report showed that gas prices went up on 18 Fridays in 2014. She said one-third of the price spikes were not justified.
She said gas distributors enjoyed a nine per cent increase in retail margins between 2013 and 2014.
"That is not acceptable," Hamel said. "Things need to change in this area."
