Expertise that is recognized

With more than 45 years of experience and a national footprint, the company delivers reliable, efficient projects that meet the highest industry standards.

1981

Founded

The company was founded in 1981 by Pierre Lajeunesse. At the time, it worked in civil engineering and the construction of large concrete structures.

1995

Entering telecommunications

Eric Lajeunesse, the founder's son and a civil engineering graduate, takes an active role at Erivan. He steers the company toward telecommunications, where his expertise and broad multidisciplinary experience meet the sector's demanding standards.

1999

Entering the Ontario market

Adapting to a constantly changing industry, Erivan opens an office in Mississauga to raise its profile and establish itself in the Ontario market.

2022

National expansion

For more than 30 years now, Erivan has built and maintained a solid reputation in telecommunications and construction. Building on its success in Quebec, it opened branches in Calgary (Alberta), Salisbury (New Brunswick) and Oakbank (Manitoba) to meet growing client demand.

2026

Leadership transition

Erivan reaches a new milestone with a significant change in its ownership. After many years of commitment, Pierre Lajeunesse hands over to Olivier Lajeunesse, who becomes a key partner in the business. This family succession carries forward Erivan's values, expertise and vision.
