Founded in 1994, Lanthier Construction was born from a clear vision: to provide construction services that are rigorous, human-centered, and sustainable. From the very beginning, the company stood out for the quality of its work, the strength of its relationships, and its keen understanding of clients’ needs.
Over the years, Lanthier Construction has experienced steady growth, expanding its expertise and strengthening its presence in the industrial, commercial, and institutional sectors. This evolution is built on a structured approach, a dedicated team, and a constant ability to adapt to the realities and demands of each project.
Today, with over 30 years of experience, the company continues to grow with the same ambition: delivering high-performing, safe projects that meet the highest industry standards. True to its founding values, Lanthier Construction continues to build lasting relationships based on trust, collaboration, and excellence.
