Medical students only access neurosurgical knowledge via brief stints in clerkships/electives and often lack mentorship and early exposure. This study sought to investigate the varying expectations about neurosurgical training held by Canadian medical students, with the goal of determining the impact of early exposure through educational opportunities and mentorship in developing interest and familiarity in the field.</p><p><strong>Methods: </strong>A cross-sectional study across Canada was conducted where students were provided with a 35-point questionnaire pertaining to mentorship, educational opportunities and interests regarding neurosurgery through REDcap. Questions were open-ended, closed-ended (single choice) or five-point Likert scale (matrix format). Interest in pursuing neurosurgery was selected as the primary outcome of this study and was dichotomized into high or low interest. Predictors of interest were determined using multivariable logistic regressions.</p><p><strong>Results: </strong>A total of 136 students from 14 accredited Canadian medical schools responded to the study.
