This study aimed to understand the relationship between intergenerational learning (as a type of active learning) and active aging in an online intergenerational learning program as an effective way to foster online intergenerational learning for senior immigrants. It examined how senior Chinese immigrants learned intergenerationally in a project initiated by the Chinese Senior Association for Chinese immigrants in Canada during the pandemic. Intergenerational learning is argued to be an effective pathway for active aging (WHO, 2002) to enhance senior immigrants' civic engagement, social security, health, and well-being. Using active aging as an analytical framework, interview data from 15 senior Chinese immigrants and two project organisers were examined. The results showed that online intergenerational learning, as a practice of active learning, promoted (a) knowledge sharing, (b) social and cultural communication, and (c) health and well-being.
