Stantec promotes Arliss Szysky to North American head of infrastructure

Stantec, an Edmonton-headquartered engineering consultancy, has promoted Arliss Szysky to EVP of its infrastructure business in North America.

Based in Calgary, Szysky has more than 25 years of AEC sector experience, including more than two decades with Stantec.

She succeeds Susan Walter, who led the infrastructure business for the last six years. Walter will transition to a role focusing on major projects, client relationships, and mentoring.

The infrastructure practice is Stantec’s largest in North America, comprising approximately 4,800 professionals and accounting for a quarter of regional revenues in 2025. The practice spans projects in ports and marine, roadways and bridges, transit and rail, airports, residential and commercial development, and landscape architecture.

“It’s an incredibly exciting time for our Infrastructure business,” said Szysky. “We have powerful opportunities to collaborate across the Company, expand our transportation business, strengthen our community development work, and build on our experience delivering projects in some of the world’s most challenging environments, including the Arctic.”

Szysky most recently spent five years as SVP and operations leader of the North American buildings practice – playing a key role in the acquisition and integration of Page. Before that, she was head of Stantec’s south Alberta region.

Prior to joining the firm in 2004, Szysky spent five years as a transportation engineer at Watt Consulting Group.

She has a bachelor’s degree in transportation from the Schulich School of Engineering at the University of Calgary and is a professional engineer.

“Arliss brings a rare combination of operational rigor, strategic vision, and genuine care for people,” said Susan Reisbord, chief operating officer for North America. “She champions continuous improvement while creating the conditions for teams to do their best work.”

Stantec has 34,000 employees across 450+ offices globally delivering services in engineering, architecture, and environmental consulting.
