Maritime energy giant Irving Oil is facing charges related to gas price fixing in Quebec, Canada’s Competition Bureau announced Friday.

Serge Parent, Irving Oil’s Quebec manager, has also been charged, the bureau said in a statement.

The bureau says the charges relate to allegations of price-fixing in three Quebec towns: Sherbrooke, Thetford Mines and Victoriaville.

The charges come weeks after a Quebec court certified a class-action lawsuit against a number of gas retailers, including Irving, that seeks $100 million in damages over price-fixing in Quebec.

That suit involves many of the same Quebec towns.

The Competition Bureau says 39 people and 15 companies have already been charged in the Quebec gas price fixing case. Six people have pleaded guilty, garnering 54 months of jail time between them, and companies have paid a total of $3 million in fines.

Allegations of gas price-fixing are not limited to Quebec. Canadian Tire and Pioneer Gas pleaded guilty in March to price-fxing charges involving gas stations in Kingston and Brockville, Ontario.

A class action lawsuit launched this spring in Ontario alleges Canadian Tire, Mr. Gas and Pioneer colluded to fix gas prices in Kingston and Brockville.

This is not the first piece of bad news for Irving Oil this week. One of its employees was injured earlier this week when an explosion rocked the oil company's refinery in Saint John, New Brunswick.

    It starts with crude oil. Although Canada may produce more oil than it consumes, the country is at the mercy of global markets for the commodity. Increased Middle East instability, sparked by popular uprisings, has lead to concerns about supply. Better-than-expected economic growth, especially in developing nations such as China and India, has also increased demand. (AP Photo/Hasan Jamali)

  • 2. Refining Oil into Gas

    The next link in the supply chain is refining. In order to turn thick, black crude oil into useful products such as gasoline, diesel, heating oil and jet fuel, it must be sent through a mind-boggling array of pipes and tanks, heaters and condensers to sort the components of the substance from lightest to heaviest. This is a complex and costly process, and is paid for by what is known as the "crack spread," or refining margin. This represents the difference between prices fetched for the products produced, and the cost of crude oil inputs.. (AP File Photo)

  • 3. Transportation to Retailers

    Once the oil has been refined into gasoline, it must be transported to retail outlets across the country. This is accomplished through a network of 23 terminals - from St. John's to Nanaimo, B.C. -- forming the backbone of the distribution network. (AP Photo/Jessica Hill)

    The retail mark-up averaged 7.6 cents per litre in April. This national average masks wide variation, from lows of 4.6 cents in Calgary up to highs of 25.8 cents in Whitehorse, according to Kent Marketing Services, an industry consulting group. (AP Photo/Orlin Wagner)
