Challenges of seniors’ use of public transportation and efforts to minimize them call upon intersectoral action. A seniors’ community group partnered with a local health agency to develop an intergenerational workshop aiming to promote respectful sharing of public transportation among teenagers. This article describes the steps of an intersectoral and interdisciplinary co-construction process in which high schools, a local health agency, the transportation sector, academia and seniors’ community organizations collaborated. This led to the development of a workshop that was both feasible and appreciated by the main stakeholders. Lessons learned from this collaborative process for developing intersectoral community-based initiatives are discussed.
