This tool is designed to support PSIs in proactive, positive, and productive ways to engage male-identified people (described in this toolkit as ‘men’) in GBV prevention work on university and college campuses. This resource is designed to be accessible to any sized institution in Canada. It provides readers with an environmental scan of what work has been or is currently underway in Canada, identifies some emerging promising practices to promote this work at an institutional level, and provides practical advice on engaging men in programming.
