Its bilingual mandate and focus on the liberal arts continue to shape Glendon's special status within York University. The new Keele Campus was regarded as somewhat isolated, in a generally industrialized part of the city. Petrol storage facilities are still across the street. Some of the early architecture was unpopular with many, not only for the brutalist designs, but the vast expanses between buildings, which was not viewed as suitable for the climate. In the last two decades, the campus has been intensified with new buildings, including a dedicated student centre and new fine arts, computer science and business administration buildings, a small shopping mall, and a hockey arena. The Aviva Centre tennis stadium, built in 2004, is a perennial host of the Canada Masters tennis tournament. As Toronto has spread further out, York has found itself in a relatively central location within the built-up Greater Toronto Area (GTA), and in particular, near the Jane and Finch neighbourhood. Its master plan envisages a denser on-campus environment commensurate with that location. Students occupied the university's administration offices in March 1997, protesting escalating tuition hikes.
