opticianry, information and communications technology, and liberal arts. The campus, initially known as Finch Campus, was renamed in 1984 after founding president
William Thomson Newnham, and is also the site of continuing education activity during the evenings and weekends. The campus includes a 1,113-bed residence, sports centre, and daycare centre. It is located west of the intersection of
Highway 404 and
Finch Avenue East . The campus's first building was opened in 1969 and has involved various architects (William H.D. Hurst (Phase 1);
John B. Parkin (Phase 2 with Searle, Wilbee and Rowland); Abram, Nowski, and McLaughlin (arena)). In 1973 a domed
planetarium was added to the Phase 3 section of the campus, but it has since closed. In fall 2011, a expansion, designed for
energy efficiency and environmental
sustainability, was officially opened at the campus. The new building, designed by Craig Applegath of Dialog, features three 80-seat classrooms; twenty-three 40-seat classrooms; fourteen 40-seat computer labs; a multi-purpose auditorium for 240 students that can be turned into a conference room or two 120-seat lecture halls; increased computing commons and library space; several new areas of collaborative student study and work space; a new "front door" for the campus; and improved campus access for people with disabilities. The
atrium in the new space was named after Frederick Minkler, Seneca's first chair of the board of governors. In 2019, Seneca's Centre for Innovation, Technology and Entrepreneurship (CITE) opened at Newnham Campus. CITE includes Seneca's innovation centre known HELIX, technology labs for
