2025 Masters (September)
The 2025 AMJ Masters was held from September 23 to 28 at the Western Fair Sports Centre in London, Ontario. It was the first Grand Slam event and first major of the 2025–26 curling season.
The field included sixty-four teams from thirteen different nations. Of note, all fourteen teams confirmed to compete in the 2026 Winter Olympics qualified. It was also the first time since the 2017–18 season that both the Chinese men's and women's teams competed in a Slam.
For the first time since [2012 The Masters Grand Slam of Curling|Grand Slam of Curling|2012], the event featured a Tier 2 bracket, hosted at the St. Thomas Curling Club in St. Thomas, Ontario. The event also held the inaugural GSOC Wheelchair Curling Invitational at the KW Granite Club in Waterloo.
New rules
For this event, a number of new rules were implemented:- Games tied after eight ends go to a draw-to-the-button shootout rather than extra ends. This does not apply to playoff games.
- Games will be worth three points in the standings, with three points being awarded to "regulation wins", two points for a shootout win, and one point for a shootout loss.
- "Thinking time" will be reduced from 33 to 31 minutes.
Qualification
The Masters consists of two tiers of 16 teams. For Tier 1, the top 16 men's and top 16 women's teams from the World Curling Federation's world rankings based on the final standings of the 2024–25 curling season were invited to participate. In the event that a team declined their invitation, the next-ranked team on the world team ranking was invited until the field was complete. Once the Tier 1 field was confirmed, Tier 2 invites were sent out to the next thirteen ranked teams. The final three spots in the Tier 2 event were regional invites sent out to Ontario based teams. The Grand Slam of Curling reserves the right to implement two sponsor's exemption in the Tier 1 men's and women's events in which one spot can be filled at their discretion.Men
