2023 Stu Sells Oakville Tankard

The 2023 Stu Sells Oakville Tankard was held from September 7 to 10 at the Oakville Curling Club in Oakville, Ontario. The event was held in a round robin format with a purse of $30,000 on both the men's and women's sides. It was the first Stu Sells sponsored event held as part of the 2023–24 season.

The 2023 event was dominated by the three Scottish teams in the field who all reached the final. The men's championship saw the reigning world champions Bruce Mouat rink, with Grant Hardie, Bobby Lammie and Hammy McMillan Jr. from Edinburgh defeat the Ross Whyte rink 6–2. Both teams entered the final with six straight wins in the event after going through the round robin undefeated. After Mouat got out to an early three-point lead, Whyte stole a single in the seventh to make the score 3–2 coming home where Bruce Mouat sealed the victory for his team. In the semifinals, Mouat won 5–1 over John Shuster while Whyte bested John Epping 7–2. It was the second final Mouat had won over Whyte to begin the 2023–24 season as he also won the 2023 Euro Super Series three weeks prior.

The lone Scottish women's team Rebecca Morrison also reached the final game where they fell 5–4 to South Korea's Ha Seung-youn rink from Chuncheon. Ha, with Kim Hye-rin, Yang Tae-i and Kim Su-jin took a single in an extra end to claim their first championship of the season. After winning the 2022 Korean Curling Championships to become the national team for the 2022–23 season, Chuncheon City Hall finished third at the 2023 championship, losing their title to Gyeonggi Province's Gim Eun-ji rink. The Ha rink advanced to the final after routing Delaney Strouse 7–0 while Morrison breezed past Tabitha Peterson 8–3 in the other semifinal game.
