"PASAN is a community-based network of prisoners, ex-prisoners, organizations, activists and individuals working together to provide advocacy, education, and support to prisoners on HIV/AIDS, HCV and related issues.
PASAN formed in 1991 as a grassroots response to the AIDS crisis in the Canadian prison system.
Today, we are the only organization in Canada exclusively providing HIV/AIDS education, support and advocacy to prisoners, ex-prisoners, young offenders and their families."
