Walsh currently serves as the General Contractor for the University of Toronto Mississauga New Science Building project. The project involves the construction of a 165,000 square feet facility to support four academic constituencies: the Centre for Medicinal Chemistry, which will be headquartered in the facility; the Department of Biology and the Department of Chemical and Physical Sciences, which will make use of the new wet research lab cluster; and the Forensic Science Program. Notably, the Centre for Medicinal Chemistry includes an Animal Care Facility for housing laboratory animals, as well as an imaging suite. Also included in the program are a high-performance computation data center and spaces for Facilities Management and Planning, both of which will support activity within the building and around campus. The New Science Building project is on track for May 2023 completion.
