Gas prices in Victoria are expected to bump up again this week as refineries make the switch to summer gasoline, according to GasBuddy.

Victorians, along with motorists living in Vancouver, Calgary, Edmonton, Regina, and Saskatoon will likely see an increase of 2 cents per litre in the next few days.

Meanwhile, cities in Eastern Canada are expected to see a more significant jump, with prices increasing by 4 to 5 cents per litre.

According to GasBuddy, a federally mandated switch to a more robust summer gasoline is the reason why gas prices will be rising.

With temperatures growing hotter in the spring and summer, refiners in Canada are required to produce a more expensive gasoline that will not evaporate in warmer weather.

“For decades, the April change-over may have flown under the radar of many drivers but indeed, federal laws require refiners to produce and sell gasoline that is less susceptible to evapouration given higher ambient temperatures in the early spring, summer and early fall driving season,” said Dan McTeague, senior petroleum analyst at GasBuddy in a release.

“The change means refiners must add more expensive components as part of their fuel processing, a cost that is inevitably passed onto motorists.”

Drivers hoping to save a few bucks at the pumps may want to fill up soon.
