Founded in 1984, the Regroupement économique et social du Sud-Ouest (RESO) is a non-profit community economic development corporation that works for the economic and social revitalization of Montréal's Sud-Ouest neighbourhoods. Its mission is to help citizens aged 18 and over in the process of returning to work or training. The counsellors assist with educational and professional information, resumé writing, job search, return to secondary school or vocational training, or finding and completing an internship.

RESO is responsible for the Carrefour jeunesse-emploi du Sud-Ouest de Montréal (CJESO). It offers young adults personalized support to help them through various personal endeavours.
