Grand Slam of Curling

2006–07 (Women's) MB Kerri Einarson (Women's)

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 were formerly 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 five men's and women's events. The original four events (Masters, Open, National, and Players' Championship) are considered to be "majors". The other slam (Tour Challenge) has a unique format that sets it apart from other events in the series.

History

In 2001, many male curlers were upset with the Canadian Curling Association (CCA). Their complaints included the long length of the 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 men's teams in the country, 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, the Grand Slam of Curling was acquired by Rogers Media via its Sportsnet subsidiary. As such, Sportsnet became the main media rightsholder of the series, although CBC Sports would still carry championship rounds of selected events.

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, but that too was cancelled along with the Tour Challenge that season. The Slam tour was back to normal for the 2022–23 season with six events, however it would be the last season for the Champions Cup which was discontinued.

In April 2024, it was announced that a consortium known as The Curling Group had acquired the Grand Slam of Curling. The group includes Jennifer Jones, John Morris and former American football player-turned curler Jared Allen, and Marc Bulger. Sportsnet will remain the Canadian broadcaster of the tour under a multi-year agreement of unspecified length.

In 2026, the Grand Slam of Curling will introduce the Rock League, which will consist of six franchised teams consisting of both males and females who will compete against each other in a league format.

It was originally called the "Capital One Cup", with the winning team awarded $50,000. It became the "Rogers Grand Slam Cup" in 2012 with the winning team given $75,000, then it became the "Bonus Cup" for the 2017–18 season, and then the "Pinty's Cup" in 2018–19, and had that name until 2022. Teams accumulate points based on their performance in each of the slams except for the Champions Cup and Tour Challenge Tier 2. Prior to 2012, the women's champions also factored in the results from the Tour Slams that were not owned by the Grand Slam of Curling.
