The Sergaz brand originates from a former Canadian oil group created in 1971.

During the 70s and 80s, Sergaz has developed an important network of franchisees throughout Quebec. In fiscal year 1984, Sergaz realized sales of $ 110 million.

The banner was sold to Ultramar in 1994 and was then gradually integrated into its existing network.

There are still a few surviving Sergaz stations, like one in Frelighsburg, Montérégie.

According to some sources, a banner revival has been seriously considered recently. But since the sale of CST to Couche-Tard and Parkland, this idea has probably been abandoned.
