This article presents an interactionist analysis of the social profiling experienced by homeless people. The data collected during an ongoing community research on social profiling in Gatineau (Quebec) were gathered from local professional agents (frontline workers and managers of community organizations) and will be analyzed in light of Howard Becker’s labeling theory (1985). By identifying the context, the profiling agents and the underlying factors, it will be possible to identify how the labeling process manifests itself in the social profiling of homeless people.
