Sticker shock: Here are the highest, lowest gas prices around northeastern Ont.

CTV QP: The carbon tax hike debate Robert Fife, Nojoud Al Mallees and Robert Benzie on which party is winning the debate over the controversial carbon tax hike.

Unfortunately, the gas prices in Ontario are not a bad April Fool's Day joke, the increase is due to the rise in the consumer carbon levy, also known as the 'carbon tax.'

While the average price for a litre of gasoline in Ontario on April 1 is $1.583, according to Gas Buddy, most of the stations in the northeast are much higher.

These are the prices for regular gas available on the Gas Buddy website as of 10:30 a.m. Monday for the four major cities in the region:

Greater Sudbury

The highest price per litre in the Sudbury area is $1.599 posted by several Esso stations around town as well as Pioneer on the Kingsway.

Costco on the Kingsway has the lowest price at $1.539/L, as of 11 a.m.. CTVNewsNorthernOntario.ca confirmed.

Those travelling south on Highway 69, might want to wait to gas up at one of the First Nations stations.

Shawanaga Gas & Variety has regular gasoline for $1.418/L as of 10:50 a.m.

North Bay

Eagle's Nest, located just outside the city, has the lowest in the North Bay area with a price of $1.457 as of 9:45 a.m.

In town, Necessities on Couchie Industrial Roade has gas for $1.469/L as of Monday morning.
