It was hosted by Ryerson University at the Mattamy Athletic Centre at the Gardens, marking the first time Ryerson had hosted, and the first time the tournament had been played in Toronto in its 53-year history. The 2015 tournament saw gold, silver and bronze medals awarded, respectively, to Carleton, Ottawa, and Ryerson. Carleton accepted the W. P. McGee Trophy, awarded to the national champions.
