The east block was the most active area of military usage and retains the only military building left on the site, the Stanley Barracks Officers' Quarters, dating to the 1840s. The area is a mix of buildings, including the older Coliseum, Horse Palace and newer buildings. The section is dominated by the exhibition complex of the Enercare Centre, Coliseum and the Industry Building. The Horse Palace (which adjoins the Coliseum and is used for equine shows and quartering), the Automotive Building (which was once used for car shows and is now a conference centre) and the General Services Building are all older exhibition buildings dating from the 1920s. The new "Hotel X" project includes a display of foundations of New Fort York which once occupied part of the site.
