All matches at the National Bank Open in Montreal were postponed due to heavy rain from the remnants of tropical storm Debby, affecting 13 scheduled contests, including three second-round men's singles matches. Top seed Jannik Sinner, who began his title defense with a victory earlier in the tournament, is now required to play twice on Saturday to stay in the competition. Tournament officials are working on a revised schedule to accommodate the delays, as the event is set to conclude with the men's singles final on Monday. The adverse weather conditions have raised concerns about the tournament's ability to finish on time. No Canadian players remain in the draw, adding to the challenges faced by organizers. The situation has created uncertainty regarding the scheduling of the remaining matches.
