From our local beginnings over 130 years ago to our vast international presence today, WSP has enjoyed continuous growth and enrichment of its service offering. Every milestone reached has enabled us to better fulfill our purpose of preparing our communities and environment for the future.


WSP Today

WSP is a globally-recognized professional services firm employing approximately 42,000 people.

We welcomed 2,500 experts from eight different acquisitions in 2016, adding to existing expertise in our Americas, EMEIA and Asia Pacific operating regions, as well as establishing our presence in three new countries: Chile, Peru and Mexico. The largest team to join us was Mouchel Consulting, a 2,000-employee engineering consulting firm operating mainly in the UK and Ireland, with a presence in the Middle East.

In 2016 Alexandre L’Heureux, our former Chief Financial Officer, transitioned to the role of President and Chief Executive Officer. Under his leadership, we made the important decision to bring together our different firms to unite under a single brand: WSP.

Always be the first choice for clients, partners and employees.
