Last summer there was an excellent music/arts festival here in Toronto (called The Manifesto) featuring some great artists, it had a strong youth/social message and it collaborated with the Urban Arts Forum.

Urban Arts Forums
The Urban Arts Forums were launched to illustrate how young artists from all backgrounds are using urban arts (hip hop, graffiti, spoken word, break dancing, etc.) to combat social exclusion and crime, and to bring about change in their communities. Forums have taken place from one end of Canada to the other, as well as in Brazil and South Africa. Featuring artists, decision makers, members of the Order of Canada and civic leaders, the forums have resulted in new community initiatives, which, on more than one occasion, have encouraged entire communities to work together.
