Tribute to one
of our founders

A cornerstone of Consultants en Gestion de Construction (CGC), Léandre Mercier was at the heart of the company’s creation in 2000.

A renowned civil engineer, throughout his distinguished career Mr. Mercier was recognized for his rigour and impartiality, which made him a well-known expert in the province.

He greatly contributed to shaping the Quebec we know today through his involvement in many major projects.

The entire team of Consultants en Gestion de Construction will always remember the precious moments and great achievements we experienced working with Mr. Mercier, a colleague who was deeply appreciated by his peers throughout his time with CGC!
