This report provides an overview of The Signal System™, a primary prevention approach designed to change social norms and behaviours that contribute to gender-based violence (GBV) in male-dominated workplaces. The Signal System™ was originally developed by Shift: The Project to End Domestic Violence at the University of Calgary, in collaboration with 13 government and community agencies via the Engaging Men Learning Collaborative.

The report articulates key features of The Signal System™ approach and takeaways for GBV professionals. It also demonstrates the impact of this approach, detailing evaluation findings that show strong engagement, and outlines next steps for implementing The Signal System™ worldwide.
