In the past decade, the Somali Canadian community has experienced a heightened rate of youth violence. Since 2005 several dozen young Somali men have lost their lives. Most of the incidents occurred in Edmonton and Toronto, with sporadic incidents in Ottawa as well. The violence, mostly concentrated in northern Alberta, attracted sustained media attention which, in turn, led to public and private discussions within the Somali community. This study explores the determinants of youth involvement in violence and related criminal activities, as well as the impact of that violence on the families of its victims and perpetrators, and the larger Somali community. The study’s design consisted of in-depth interviews with Somali Canadians and non-Somali key informants, in the three cities where the majority of the Somali population resides, to elicit their explanations of the violence, and their perceptions of its impact. Results indicate that the proximal determinant of the violence was the young men’s participation in the drug trade in northern Alberta. Distally, determinants of the violence link three intersecting themes: poverty, racialization and gender. Poverty and racism marked the early lives of the male youth and their families in Ontario. The resettlement barriers experienced by first generation Somali refugees, the racism that this community and its youth encountered in public institutions such as schools, the criminal justice system and the media, and the anti-poor posture of neoliberalism, combined to create vulnerabilities to risky behaviour in male youth. My analysis suggests that young men entered the drug trade and/or participated in criminal activities in order to fill material needs and enhance their self-esteem. The inequities that underpin the determinants of violence require remedy at multiple levels. I propose an evidence-based population health framework for the prevention of youth violence, and identify interactive levels (individual, community, institutional, societal) at which to target prevention and intervention efforts.
