The Grand Slam of Curling (currently known as the Pinty's Grand Slam of Curling is a series of curling bonspiels that are a part of the annual World Curling Tour. Grand Slam events offer a purse of at least CAD$100,000, and feature the best teams from across Canada and around the World. The Grand Slam was instituted during the 2001-02 season for men and 2006-07 for women, but some of the Grand Slam events have longer histories as bonspiels.
Grand Slam games are played in eight ends, instead of the standard 10 ends seen in other major international tournaments. This came into effect for the 2006-07 season.
The Grand Slam of Curling was previously operated by the sports media company Insight Sports. In August 2012, Rogers Media, through its Sportsnet division, acquired the series. As such, television rights to the series have also defaulted to Sportsnet, though certain events may still air championship rounds on CBC.
The Grand Slam season consists of seven men's and six women's events. The original four events (the Masters, Canadian Open, the National and the Players' Championship) are considered to be "majors".
The GSOC Tour Challenge was introduced in the 2015–16 curling season.
The Masters of Curling has been held 16 times, the most recent being in Okotoks, Alberta. The event was known as the World Cup of Curling between 2009 and 2011.
The National has been held 16 times, the most recent being in Sault Ste. Marie, Ontario.
1 There was no National in the 2004-2005 season, but the BDO Curling Classic was held. It returned to its original name in the 2005-2006 season. The words "BDO Classic" were added to the name of the Canadian Open.
The Canadian Open of Curling has been held 16 times, the most recent being in North Battleford, Saskatchewan.
The Elite 10 was started in 2015, and was last held in Port Hawkesbury, Nova Scotia.
