York University but that too failed. At the time of its demolition, Varsity Stadium was the second largest capacity stadium in Canada with a grass field, after Commonwealth Stadium in Edmonton, Alberta (however, that stadium has since switched to an artificial playing surface). The stadium opened in 2007. Facilities and features built in the first phase of the stadium's reconstruction include an IAAF Class II 400m eight-lane track, artificial field turf (FIFA 2 Star rated surface by Polytan), and a winter bubble enabling use during inclement weather. The multi-use capability was one of the main reasons that the plan was passed by the governing council, as opposed to the 25,000 seat stadium. Compared to the old Varsity Stadium, the seating is closer to Varsity Arena, almost making the two structures one conjoined complex. Part of the red brick wall along Bloor Street was maintained for historic purposes, but the new facility is much more open and visible from the streets overall. The new facilities are designed by Diamond and Schmitt Architects. Following the renovation, the Argonauts returned to the stadium, hosting their 2013 preseason game at their former home. Their 2014 and 2015 preseason home games were also scheduled for the stadium. For the 2015 Pan American Games the facility hosted archery between July 14 and 18. During the games, the facility was configured to hold roughly 2,000 spectators per session. The facility also hosted the archery events of the 2015 Parapan American Games Major events In addition to hosting several University of Toronto athletic programs, the stadium has also hosted several events including military, musical, and sporting games.
