2017 Rogers Cup – Women's singles

Elina Svitolina defeated Caroline Wozniacki in the final, 6–4, 6–0 to win the women's singles tennis title at the 2017 Canadian Open. It was her third consecutive Premier 5 title, making her the first woman to win the first three Premier 5 tournaments in a season, as well as the first to win three consecutive Premier 5 tournaments since Wozniacki won Montreal and Tokyo in 2010 and Dubai in 2011. This was also Wozniacki's sixth consecutive loss in a final in 2017, making her the first to lose that many finals in a row in one season, as well as the first woman to lose six finals in a single season since Maria Sharapova in 2012.

Simona Halep was the defending champion, but lost in the semifinals to Svitolina.
