Hardball Doubles Squash was invented in Philadelphia, PA in 1907 and was standardized in the early 1920s. Today, there are four major doubles organizations overseeing more than 15,000 players in North America: Squash Canada, U.S. Squash, the Squash Doubles Association (SDA) and Women’s Doubles Squash Association (WDSA). These four groups manage all aspects of doubles play, from beginner to elite professional, and work together to grow and promote the game.
Hardball doubles has been a fixture of Canadian Squash since the early 1930s. Five Canadian provinces (British Columbia, Alberta, Manitoba, Ontario and Quebec) house all 36 courts in the country. The Canadian Doubles National Championships were first played in 1934 and, with the exception of 1938, have been played every year since then. Provincial Championships are held in four of the five provinces and over 1,100 players participate in Doubles Squash leagues across the country. It is estimated that there are over 4,000 hardball doubles players in Canada.
