The original National Tennis Centre in Toronto was located in the north end of York University's Keele campus next to the Metro Toronto Track and Field Centre. Originally the courts were clay, they were later changed to Har-Tru. The site was too small for the growing tournament, as pressure from the ATP + WTA Tours collectively forced the building of a new site on the west end of York University. The site had 6 courts for play, and 4 practice courts (used for housing player facilities). The structure was an open air stadium with wooden seats and was not suitable for a first class tennis tour. The stadium held roughly 10,000 fans, and a second show court held roughly 2,000. In 2003 the stadium was torn down and replaced by the Rexall Centre, located to the west of this site. The current site is not vacant, with only centre court being demolished. 8 of the outer courts are still present.
