Seeded players§

The after are the seeded players. Seedings are based on WTA rankings as of 27 July 2026. Rankings and points before are as of 3 August 2026. Even though the tournament takes place one week later this year, players will still defend their points from the 2025 tournament held in Montreal during this year's tournament, as the 2025 results were postdated and will drop on 10 August 2026. This method of calculating ranking points for the tournament is different from the ATP's method.

∆ The player is defending points from her 18th best result or her sixth best combined WTA 1000 tournament result. Ω The player is keeping her sixth best combined WTA 1000 tournament result as it is higher than the Toronto result, which does not need to be counted in her ranking points. § The player is defending points from a WTA 125 tournament (Warsaw).

Withdrawn seeded players§

The after players would have been seeded, but withdrew before the tournament started.
