Abstract Purpose Most Canadian hospitals face significant reductions in operating room access during the summer. We sought to assess the impact of longer wait times on the oncological outcomes of localized prostate cancer patients following roboticassisted radical prostatectomy (RARP). Methods We conducted a retrospective review of a prospectively maintained RARP database in two high-volume academic centers, between 2010 and 2019. Assessed outcomes included the difference between post-biopsy UCSF-CAPRA and postsurgical CAPRA-S scores, Gleason score upgrade and biochemical recurrence rates (BCR). Multivariable regression analyses (MVA) were used to evaluate the effect of wait times. Results A total of 1057 men were included for analysis. Consistent over a 10 year period, summer months had the lowest surgical volumes despite above average booking volumes. The lowest surgical volume occurred during the month of July (7.1 cases on average), which was 35% less than the cohort average. The longest average wait times occurred for patients booked in June (93 ± 69 days, p
