Toronto Adult Student Association (TASA) is a non-profit organization created to promote and embrace the principles and values of life-long learning for the adult student sector. TASA was founded to develop and implement appropriate student support services, and to provide students with a platform to collectively express their concerns. TASA identified a void in both the service offerings and program funding for adult learners. In recent years, the educational environment has substantially reduced two- thirds of its funding to adult learners, which has created a current reduction of enrollment figures by 70%.
