Gagnon Group

Gagnon, it’s not recent history!

The Gagnon brothers were born in a small village on the borders of the Beauce and the Asbestos region. From an early age, they were called to work on their father's farm, an experience they all consider to have been the principles that still guide them to this day. 

In 1953, Roland Gagnon founded a small business in the Villeray district of Montreal to recondition batteries and resell them.

In 1960, the two youngest members of the family, André and Claude, joined their older brother's business.

In 1969, all five brothers came together to manage Gagnon. 

In 1971, the company relocated to its current location on Metropolitan Boulevard in Saint-Léonard and opened the service centre for car and truck repairs.

In 1988, Claude and André bought out their brothers' shares and became the sole shareholders of Gagnon. A few years later, a major expansion of the repair centre has allowed for better customer service. 

Claude and André are still in business together, and have been for more than 60 years now! January 1, 2020 saw the arrival of Jean-Michel Bibeau, who joins the group as a partner and, as such, takes over
