Behind every project, a committed team
At the heart of Lanthier Construction’s success is a team of passionate professionals who share a common commitment to excellence. Estimators, project managers, superintendents, coordinators, and administrative experts work hand in hand to deliver projects that meet the highest standards of quality and collaboration.
Among them, Mathieu Gosselin, ing., Construction Director, and Sonia Pelletier, BAA, Director of Financial and Administrative Services, exemplify the company’s spirit of dedication and professionalism. Their complementary expertise — one grounded in technical precision, the other in organizational and financial stewardship — strengthens the cohesion and performance of a multidisciplinary team that reflects Lanthier’s culture of loyalty, trust, and mutual respect. With an average tenure of ten years, this experienced group anticipates challenges, finds creative solutions, and maintains a proactive approach from design to delivery.
More than colleagues, they form a cohesive team driven by shared values and purpose: one that embodies the rigor, collaboration, and integrity at the core of Lanthier Construction’s success.
Innovation also plays a crucial role in Lanthier Construction’s success. The company continually refines its processes, adopting digital collaboration tools that enhance coordination and accuracy, especially for complex industrial and pharmaceutical projects. Prefabrication and sequenced construction methods are also integrated to reduce schedules and improve quality.
Safety, a cornerstone of every construction operation, is treated at Lanthier with the same rigor as design and execution. Working in heavily regulated sectors requires constant vigilance and discipline. “Maintaining high health and safety standards is a constant challenge,” says Lanthier. “We address it through a deep-rooted prevention culture, ongoing training, and structured communication. Every team member plays an active role in ensuring safe worksites.”
As a multi-generational family business, Lanthier Construction draws strength from its continuity and values. “Being a family business brings a long-term vision and authentic culture,” Lanthier says. “Our principles of rigor, respect, and passion guide every decision and strengthen our relationships with clients and partners.” This culture of integrity has created a foundation for lasting success and repeat business across Quebec’s construction markets.
Sustainability has also become central to the company’s philosophy. Lanthier integrates environmental responsibility throughout every project, from material selection to energy system design. “We prioritize responsible material choices, waste reduction, and the integration of high-performance systems,” Lanthier notes. “Our goal is to deliver efficient, healthy, and environmentally conscious spaces that meet modern standards.”
The company’s adaptability and collaborative spirit were tested recently on an industrial project that revealed unforeseen structural issues during construction. Rather than delay progress, the Lanthier team, engineers, and the client quickly designed a safe technical solution. The experience reaffirmed the firm’s belief in flexibility and communication as essential tools for success.
Looking ahead, Lanthier Construction sees opportunity in Quebec’s evolving commercial and institutional markets. “There’s a growing focus on modernizing existing spaces, integrating smart technologies, and achieving higher environmental performance,” Lanthier explains. To stay ahead, the company is investing in digital project management tools and expanding its technical expertise to meet rising expectations.
After more than 30 years, Lanthier Construction continues to exemplify the qualities that built its reputation: precision, professionalism, and partnership. It has grown from a respected local builder into a trusted leader capable of delivering complex, high-performance projects across multiple sectors. Yet at its core, the company remains deeply human, driven by family values, respect for its craft, and an unwavering commitment to client success.
“Our team is our greatest asset,” says Lanthier. “Across all our projects, whether interior redevelopments or new builds, we bring the same rigor, creativity, and passion. That’s what makes Lanthier Construction a trusted partner for complex and ambitious projects.”
