stadium had a large grandstand on one side of the field, with a small section curving around the end zone, and a separate grandstand on the opposite side of the field, with a capacity of just under 29,000. In 2011, plans were announced to renovate the stadium again in 2012, with a completion date in 2014, and the stadium would also be used for the then upcoming 2015 Pan American Games. On February 25, 2011, the Toronto 2015 Pan Am board of directors approved stadium plans which would see the south side stands demolished and rebuilt and the north side stands extensively renovated. However, that plan was not used. A new plan announced August 31, 2011, called for a brand-new $150 million stadium with a new north-south field alignment that would provide equal advantage for sports where prevailing wind direction and sun glares are equal for both teams. It would be a multi-function stadium, hosting concerts and football, soccer, and hockey games. During construction, the Tiger-Cats played at the University of Guelph's Alumni Stadium for the 2013 season, and proceeds from the temporary site agreement went to the Gryphon Athletics fundraising campaign as a part of the University of Guelph’s BetterPlanet Project.

The Bills, playing the entire game under Canadian rules, lost 38–21. The game marked the only CFL–AFL meeting where the CFL team won. Some concerts have occurred at Ivor Wynne. The biggest was Pink Floyd in 1975, during which a pyrotechnics display damaged the scoreboard. The last concert held at Ivor Wynne was Rush in 1979 until the Tragically Hip played on October 6, 2012 before departing for an American tour. In April 2005, Ivor Wynne hosted Our Game to Give, a charity hockey game instigated as a result of the 2004–05 NHL lockout. Nearly 20,000 spectators braved inclement weather to watch locked-out NHL players and a handful of former professionals lace up the skates at an outdoor charity hockey game. Hockey Hall of Famer Gordie Howe dropped the puck for the ceremonial faceoff. Team Gilmour rallied in the third period to defeat Team Staios 11-6. Proceeds of the Our Game To Give event went to the Tsunami Relief Fund of the Canadian Red Cross and Camp Trillium, the
