Supplemental data: Perceived training gaps of newly licensed veterinarians and impact of single-instance peer mentorship participation in Ontario, Canada - Interviews with mentors

A total of 11 veterinarians met our inclusion criteria as active peer advisors. Interviews were conducted with 10 participants from, with three (30%) participants identifying as men and seven (70%) as women. The average age of participants was 58 years (median = 59, range = 46 to 68) and average time in veterinary practice was 33 years (median = 33, range = 20 to 43). Among our participants, eight (80%) were companion-animal veterinarians, one (10%) was a mixed-animal veterinarian, and one (10%) was a veterinary specialist. Four of our participants (40%) had a graduate degree (e.g., MSc, PhD, MBA). Interviews were held from January 14 to March 20, 2025. Data collection was stopped once additional insights were unlikely to result from further interviews (i.e., data saturation). Interviews lasted an average of 52 minutes (median = 52, range = 33 to 74).
