The 2023 Princess Auto Players' Championship was held from April 11 to 16 at the Mattamy Athletic Centre in Toronto, Ontario.

In the women's final, Sweden's Isabella Wranå won her first Slam title, defeating the World Champion Silvana Tirinzoni rink from Switzerland 6–5.

Up 1–0 after the first, Koe missed a long raise takeout in the second, allowing Schwaller's last rock thrower Benoît Schwarz to draw for two.

Koe made a hit and stick for one in the fifth, and Schwarz replied with a draw to the button in the sixth to go up 4–2.

Koe was in a similar situation in the semifinal, where he had to make a slash double against the Brad Gushue rink with only seconds on remaining on his clock.
