From the National Bank Open's Tournament Policies:
The National Bank Open's Tournament Policies say to stay in your designated seat, where applicable, until the end of play. You may leave only during a player changeover. Avoid making noise during play and follow staff directions if prompted.
Under the 2026 WTA Rulebook, noise, "out" calls or similar distractions from spectators are not considered a hindrance, so the point stands as played. That is a rule for players and officials, not permission for fans to call out.
From the National Bank Open's Tournament Policies:
From the National Bank Open's Rain and Cancellation Policy (applies to tickets bought directly from Tennis Canada or Ticketmaster; the policy covers extreme heat, poor air quality, protests, authority alerts or directives and other events beyond the organizers' control):
Under the 2026 WTA Rulebook, all WTA 1000, WTA 500 and WTA 250 tournaments, on any surface, must use a WTA-approved live electronic line calling (Live ELC) system. It must be available on all match courts from the first day of qualifying until the end of the tournament.
The men's ATP rulebook could not be checked for this guide.
From the 2026 WTA Rulebook (the Rulebook does not name individual tournaments, so check the tournament for its exact draw size):
Main draw: made up of direct acceptances, qualifiers, wild cards and alternates.
Qualifiers: players who win through the qualifying competition. The number depends on the draw size, for example:
Wild cards: a WTA 1000 Mandatory 96-player main draw has 8 wild cards and a 48/56 draw has 4. A 48-player qualifying draw has 6 wild cards and a 24/32 draw has 4.
Lucky losers: players who lose in qualifying but are placed in the main draw to fill a vacancy, chosen by the round reached in qualifying and then WTA singles ranking.
Match format: qualifying singles are best of three tie-break sets.
Under the 2026 WTA Rulebook:
This is the WTA rule for women's events. The men's ATP rules were not checked for this guide.
Under the 2026 WTA Rulebook, every WTA 1000, WTA 500 and WTA 250 tournament must have electronic serve clocks, controlled by the chair umpire's tablet, on each match court from the first day of qualifying through the main draw finals. Each court needs at least two clocks visible to the players and chair umpire, placed on the back wall or corner on the far left and far right sides from the chair.
Time limits before a Time Violation:
A server gets a Time Violation warning for the first offence and a Time Violation fault for each later one. A receiver gets a warning, then loses a point for each later one.
Noise or "out" calls from spectators are not treated as a hindrance, so the point stands as played. Fans should stay quiet during points.
The 2026 WTA Rulebook allows off-court coaching during play, in a non-disruptive manner:
This applies to WTA tournaments. The men's ATP rules were not checked for this guide.
