Aecon Group 

Founded in 1877 and headquartered in Toronto, Canada, Aecon Group Inc. offers comprehensive construction and infrastructure development services. Operating through its subsidiaries, the company caters to both public and private sector clients across Canada, the United States, and international markets. Aecon's activities are structured into two core segments: Construction and Concessions. The Construction segment primarily focuses on critical areas such as civil infrastructure, urban transportation systems, nuclear power facilities, utility networks, and conventional industrial projects. In contrast, the Concessions segment specializes in the entire project lifecycle, from development and building to financing and ongoing operation, frequently utilizing public-private partnership (PPP) models. The organization was formerly known as Prefac Concrete Co. Ltd., officially changing to Aecon Group Inc. in June 2001.
