Heavy rain forced the postponement of matches at the National Bank Open for two consecutive days, creating a significant scheduling backlog at Montreal's IGA Stadium. The inclement weather affected play on August 2 and August 3, 2026, extending the tournament timetable and delaying the completion of scheduled contests.

The National Bank Open organizers, in coordination with Tennis Canada, confirmed that the rain made the courts unplayable, necessitating the suspension of all matches for the duration of the storm. The interruption impacted both men's and women's draws, with the tournament officials working to reorganize the order of play once conditions improved.

Tournament officials indicated that the two-day delay will require adjustments to the remaining match schedule, though specific revisions to match times and court assignments were not detailed. Players and fans were advised to stay updated through official channels as the revised timetable is finalized.

In related news, Tennis Canada announced at the end of June that the IGA Stadium will undergo a renovation project that includes the installation of a retractable roof. The upgrade is intended to mitigate future weather disruptions, but the construction is projected to take several years before completion. Until the roof is operational, the tournament remains vulnerable to weather-related interruptions such as the recent heavy rain that caused the current delay.
