The 2005 Canada Summer Games were held in Regina, Saskatchewan, during 6–20 August 2005. This was the 20th edition of the games and marked the province's centennial year. 3,511 athletes competed in 101 events across 16 sports, including the first appearance of women's wrestling at the games. The games also had the first appearance of diversity ambassadors and athletes competing in multiple sports. Attendance was estimated at 12,000 visitors.
Venues included the Centre for Kinesiology at the University of Regina and the Eventplex at Regina Exhibition Park (now part of the REAL District). The planning and execution of the games was overseen by the Project Management Institute, coordinating 6,000 volunteers on a 40-month project with a budget of $23.4 million. The games concluded with a financial surplus which benefited the Dreams and Champions legacy program, and more than $600,000 of sporting equipment was donated to organizations in the area. The upgrades to Regina's sports facilities led to the city bidding for the 2008, 2011 and 2014 North American Indigenous Games (NAIG), ultimately hosting in July 2014.
