Y'a QuelQu'un l'aut'bord du mur (YAM) is a green-hearted organization with a mission to have a positive impact on the environment by engaging the community. Founded in 2003 in response to the issue of incivility in the Hochelaga-Maisonneuve neighborhood, YAM focuses on urban revitalization and socio-professional integration of young individuals in need. The organization offers comprehensive graffiti removal services, implementing alternatives like murals and green walls throughout the Greater Montreal area.

Partnering with the Mercier-Hochelaga-Maisonneuve Borough, YAM has expanded its expertise to include eco-district programs. In 2009, YAM launched the Solidarity Landscape project, promoting urban agriculture and supporting food security initiatives through the establishment of community gardens and seasonal markets. The organization's commitment to environmental interventions has earned them the management of the Eco-District program in Mercier-Hochelaga-Maisonneuve.

Through their recognized expertise, YAM continues to develop new social and environmental projects aimed at improving the well-being of citizens in collaboration with over 100 partners
