Due to an injury to regular starter Clint Irwin in July 2016, Bono was selected to be the number one keeper for the first team by manager Greg Vanney; he went on to make 16 MLS appearances for the club that year, and also started in the second leg of the 2016 Canadian Championship final against Vancouver Whitecaps on June 29, which Toronto won on away goals, but Irwin later regained the starting spot for the remainder of the regular season and the Playoffs, as Toronto went on to reach the 2016 MLS Cup Final, only to be defeated at home by the Seattle Sounders 5–4 on penalties, following a 0–0 draw after extra time.
