The 2015 Pan American Games, officially the XVII Pan American Games and commonly known as the Toronto 2015 Pan-Am Games (French: Jeux panaméricains de 2015 à Toronto), were a major international multi-sport event celebrated in the tradition of the Pan American Games, as governed by Pan American Sports Organization (PASO). The games were held from July 10 to 26, 2015 in Toronto, Ontario, Canada; preliminary rounds in certain events began on July 7, 2015. These were the third Pan American games hosted by Canada, and the first in the province of Ontario. The Games were held at venues in Toronto and seventeen other Golden Horseshoe communities. The Pan American Games and 2015 Parapan American Games were organized by the Toronto Organizing Committee for the 2015 Pan and Parapan American Games (TO2015).
The Games hosted 6,132 athletes representing 41 National Olympic Committees (NOCs) in the Americas, marking the largest multi-sport event hosted in Canada, in terms of athletes competing. A record of 45% of competitors were women, the most ever for any multi-sport event. 364 events were contested in 36 sports, which included the 28 sports contested at the 2016 Summer Olympics; certain sports also served as qualification paths for these Olympics. Canoe slalom and golf made their Pan American Games debut, as well as women's competitions in baseball, C-1 canoe and rugby sevens.
The Canadian Olympic Committee chose Toronto and the surrounding region as the Canadian candidate. No other Canadian city was given a chance to bid in a domestic race, and thus Toronto was selected without a vote. Toronto's interest in bidding came after failing to land the 1996 Summer Olympics and the 2008 Summer Olympics, which were held in Atlanta and Beijing respectively.
On February 23, 2009, Toronto City Council and Hamilton City Council approved the bid and confirmed their intentions to support the successful hosting of the event. The official bid book document was submitted to the Pan American Sports Organization (PASO) on May 27, 2009.
PASO made an evaluation visit to Toronto between August 30 and 31, 2009. The team analysed the candidate city features and provided its feedback back to voting members of PASO. The evaluation committee was headed by Julio Maglione, a member of the IOC representing Uruguay and the head of Fédération Internationale de Natation (FINA), the international swimming federation. After the visit Maglione said, "Toronto has all the conditions to play host to the Pan American Games."
Toronto won the bidding process to host the Pan and Parapan American Games by a vote of the Pan American Sports Organization on November 6, 2009, at the PASO Session held in Guadalajara, Mexico. The result was announced by PASO President Mario Vázquez Raña. Toronto faced two other finalists shortlisted Lima, Peru, and Bogotá, Colombia. Toronto earned 33 votes, while contesting candidate cities Lima and Bogotá received 11 and 7 votes, respectively. Then-Mayor of Toronto Rob Ford and Canadian Minister for Sport Bal Gosal received the Pan American Sports Organization flag during the closing ceremony of the 2011 Pan American Games in Guadalajara, Mexico.
