The National Bank Open has been severely affected by adverse weather conditions, leading to the cancellation of an entire day's schedule. Persistent rain in Montreal made it impossible to play the four men's quarterfinal matches that were planned. Unfortunately, without a roof available on any of the courts, tournament organizers had no contingency plan to accommodate the weather, resulting in the decision to postpone all matches until Tuesday. This disruption highlights the challenges faced by outdoor tournaments and the impact of weather on scheduling in professional tennis.
