The Grand Slam of Curling (formerly branded as the Pinty's Grand Slam of Curling for sponsorship reasons) 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 (with the 2006 Players' Championship also considered a Slam), but some of the Grand Slam events have longer histories as bonspiels.
The Grand Slam season consists of six men's and women's events. The original four events (Masters, Open, National, and Players' Championship) are considered to be "majors". The other two slams (Tour Challenge and Champions Cup) have unique formats that set them apart from other events on the World Curling Tour.
History
In 2001, many curlers were upset with the Canadian Curling Association (CCA). Their complaints included the long curling season, not getting any prize money at the Brier, the national men's curling championship, which generated millions for the CCA, and the inability to have sponsors at the Brier. Eighteen of the top twenty curling teams, known as the "Original 18", agreed to boycott the Brier from 2001 to 2003 and created the Grand Slam of Curling. The original 18 skips were Dave Boehmer, Kerry Burtnyk, Pierre Charette, Glen Despins, Dale Duguid, Bert Gretzinger, Glenn Howard, Bruce Korte, Allan Lyburn, William Lyburn, Kevin Martin, Greg McAulay, Wayne Middaugh, Kevin Park, Brent Pierce, Vic Peters, Peter Steski and Jeff Stoughton.
The Grand Slam of Curling began in the 2001–02 curling season with four events: the Canadian Open, Masters, National, and Players' Championship, the four "majors".
After the merger of the Women's Tour and the WCT, the 2006 Players' Championship featured a women's event for the first time, and was considered a Slam for the women too. In the 2006–07 curling season, several existing women's events were designated as Grand Slams, but were not operated by the Grand Slam of Curling. Grand Slam games also got reduced to eight ends that season.
In 2012, Sportsnet purchased the Grand Slam of Curling. As such, television rights to the series have also defaulted to Sportsnet, though certain events may still air championship rounds on CBC.
In 2017, Yare TV began broadcasting online streams of the Grand Slams, opening up access to fans outside of Canada.
Under this new ownership, the separate women's Grand Slams were phased out, with women's divisions added to existing men's Grand Slams. New Grand Slam events were also added: the Elite 10 in the 2014–15 curling season and the Tour Challenge and Champions Cup in the 2015–16 curling season. A women's division was added to the Elite 10 in the 2018–19 curling season, achieving for the first time equal number of events, prize money, and television time for men and women. The Elite 10 was dropped the next season, bringing the number of events to six.
The COVID-19 pandemic cancelled the remaining two slams of the 2019-20 curling season and all but the remaining two slams of the 2020–21 curling season. The 2020–21 season was supposed to include the first international Grand Slam, the Canadian Open (renamed to the Open) to be held in Las Vegas, Nevada, United States.
