The COVID-19 pandemic exacerbated gender-based violence (GBV) rates in Canada, especially affecting young women and gender-diverse youth. Trauma- and violence-informed physical activity and sport for development (SFD) are recognized strategies for supporting survivors of violence, preventing GBV, and challenging gender norms. This paper explores the potential of trauma- and violence-informed approaches with a Canadian SFD organization, focusing on programs aimed to promote gender diversity and address GBV. Grounded in intersectional feminism and queer theory, findings from interviews with SFD staff and participants (n = 15) revealed challenges in maintaining a trauma- and violence-informed approach in a heteronormative sporting space. In conclusion, further research on trauma-informed SFD is crucial due to increasing GBV rates in sport.
