Equity, diversity, inclusion, and Indigenization (EDII) are essential components of fostering excellence and innovation in research environments. The McDonald Institute, Canada’s national research network for astroparticle physics, has developed a suite of EDII initiatives aimed at addressing systemic barriers and promoting equity within the field. This presentation will critically examine the Institute’s strategic approach to EDII, highlighting programs such as the Cross-Disciplinary Internship (CDI), which integrates students from diverse academic backgrounds into astroparticle physics research, and initiatives supporting Indigenous student participation and gender equity, including the Women+ in Physics Canada (WIPC+2025) conference. Drawing on annual reporting data and collaborative frameworks, the McDonald Institute’s efforts exemplify how embedding EDII principles within organizational structures can lead to transformative cultural change. The discussion will explore key achievements, ongoing challenges, and the broader implications for integrating EDII into research institutions.
