An innovative company since its inception

OSM Atlantic's roots are in the Magdalen Islands, in the early 2000s. Jacques Aucoin, the company's co-founder, was working as a machinist at Hydro-Québec's diesel power plant in Cap-aux-Meules. Noting that repairs were always accompanied by long delays and significant costs, he decided to develop a high-precision machine based on laser guidance technology. Named "the Bore", this technology soon proved its speed and efficiency.
The Bore continued to be improved and refined over the years, always with the contribution of Jacques Aucoin, who then founded OSM Atlantic in 2015 in partnership with the Coopérative de Transport Maritime et Aérien (CTMA, which has since sold its interest). Based in Cap-aux-Meules, the company relies on its proprietary technology to offer specialized repair and machining services to diesel-driven power plants and shipping companies.
In 2017, Jacques Aucoin passed the torch of OSM Atlantic’s management to his son Jean-Sébastien. Always looking ahead and aiming to offer the best to its customers, the company earned its ISO 9001:2015 certification in 2021. With its vast technological know-how and its proven capacity for innovation, the company is now growing rapidly and is proud to work in partnership with its clients on land and at sea.

A company committed

To its community

We are committed to the economic and social development of our local community. This is why we focus our management on innovation, on co-development and on resource-sharing between companies on the Magdalen Islands.

OSM Atlantic contributes financially to the Desjardins multi-sport center project, supports local economic development strategies and adapts its mechanical services to the needs of the community.

For the environment

Our commitment to sustainable development is reflected in our activities and daily actions.

Our services are designed to optimize the performance and energy-efficiency of diesel engines, in addition to extending their lifespan. In doing so, we strive to reduce the environmental cost of a malfunctioning engine or the purchase of a new engine.

A management team with vision

The management team surrounds itself with like-minded passionate people, who view customer relationships as partnerships. Together, they push OSM Atlantic's expertise even further.
