“Once asked to leave the shelter a victim of trafficking can live on her own. In doing so she will face significant challenges, including, but not limited to, stigma, isolation, financial hardship and uncertainty, a sense of physical insecurity and the subjective fear of being found either by their families or former traffickers. Some women have the capacity to negotiate these challenges without undue hardship. There will however be victims of trafficking with characteristics, such as mental illness or psychological scarring for whom living alone in these circumstances would not be reasonable. Whether a particular appellant falls into that category will call for a careful assessment of all the circumstances.”
