Headquartered in Montreal, Canada, and publicly listed on the Toronto Stock Exchange, we combine future-focused thinking with technical expertise to power local impact while leveraging our global scale.

We plan, advise, design, manage and engineer long-lasting solutions that benefit generations to come. Our work spans property and buildings, transportation and infrastructure, earth and environment, water, energy, and federal programs. We provide services to transform the built environment and restore the natural environment, with expertise ranging from environmental remediation to urban planning, from engineering iconic buildings to designing sustainable transport networks, and from developing the energy sources of the future to enabling new ways of extracting essential resources.

Our commitment to sustainability is demonstrated through our science-based emissions reduction targets and our position in the top 5% of global companies for ESG performance, earning us EcoVadis Gold recognition.

Sustainability is at the core of our strategy. We have committed to achieving net zero emissions across our value chain by 2040, with science-based targets approved by the Science-Based Targets initiative. We have reduced our Scope 1, 2 and 3 GHG emissions by over 58% compared to our 2018 baseline. Our biggest impact comes from the projects and services we deliver—approximately 51.5% of our global revenues come from services that have a positive environmental impact and support the UN Sustainable Development Goals. We have been recognized as one of Corporate Knights' 2025 Global 100 most sustainable corporations, included in the Dow Jones Best-in-Class North America Index, and ranked in the top 5% of companies by EcoVadis for environment, labour and human rights, ethics, and sustainable procurement. We are also recognized as a climate change consulting leader, helping clients develop strategies to mitigate emissions, enhance sustainability, and identify climate-related risks and opportunities.

We give back to the communities where we live and work with time and resources through our philanthropic program, Thrive, which is linked to our contribution to the United Nations' Sustainable Development Goals. Our efforts take the form of investments, partnerships and pro-bono expertise, all guided by the passion of our people. Our employees are committed to giving back, and we generally employ a regional approach to supporting communities so that our contributions are meaningful and locally relevant. We partner with organizations like Water For People, uniting over 6,500 WSP water professionals in a global effort to ensure clean water and sanitation for all.

Our commitment to Inclusion and Belonging is a central pillar of our culture and values. We stand at the forefront of efforts to foster inclusive working environments in which everyone can thrive. We promote a culture in which inclusion is expected and valued—our goal is to create trusting, collaborative and psychologically safe work environments where every single person feels they belong and everyone is empowered to speak up and be their authentic selves. We measure our employees' sense of belonging regularly through our engagement survey and report on our progress annually. We are proud of our dynamic employee groups around the world, including Women of WSP, LGBTQ+, and Indigenous groups, all supported by a global network. These groups play a key role in promoting STEM fields to inspire the next generation and contribute to a more diverse industry. We believe that by supporting and promoting an inclusive and diverse workplace, our employees can tap into their full potential, unleashing innovation, ingenuity, and adaptability.
