2018 Elite 10 (September)

The 2018 Princess Auto Elite 10 was held from September 26 to 30 at St. Clair Campus Arena in Chatham, Ontario. It was the first Grand Slam of Curling event held in the 2018-19 curling season, and the first time the Elite 10 had a women's division. It was also the last time the event was held, as it was removed from the Grand Slam lineup for the 2019-20 curling season.

On the men's side, defending champions Brad Gushue won the event, their eleventh grand slam, beating out the new Reid Carruthers rink 1 UP in the final.

On the women's side, Olympic champion team Anna Hasselborg won their first grand slam event. They defeated team Silvana Tirinzoni 4-and-2, who were looking for their second ever grand slam victory.

Format
Instead of normal curling scoring rules, the Elite 10 uses a match play system in which scoring is based on ends won, rather than rocks scored. An end is won by stealing or scoring two with the hammer, similar to skins curling. Unlike skins, however, there are no carry-overs. In the event of a tie, a draw to the button competition is held to determine the winner. In the standings, wins are worth three points, draw to the button wins are worth two points, and draw to the button losses are worth one point. At the end of the round robin, the top six teams (regardless of pool) advance to the playoffs, with the top two advancing to the semifinals automatically.

Qualification
