Organisers of the Montreal event have raised concerns after top players Jannik Sinner and Novak Djokovic withdrew from the tournament, which serves as a US Open tune-up. The tournament director of the Canadian Open, a Masters 1000 event, said changes need to be made to what he described as the 'demanding schedule' of players.

Both Sinner and Djokovic skipped the Montreal event. The director specifically pointed to the calendar's intensity as a contributing factor.
