The concept of knowledge mobilization (KMb) is prominent in governance frameworks of tri-council funding in Canada. Yet there are a number of conceptual and practical challenges when such ideas are proposed for adoption across large multidisciplinary contexts. This research note introduces the concept of
critical knowledge mobilizationas a way to understand KMb in large multidisciplinary teams and social gerontology. It begins with a high-level sketch of the historic changes in knowledge production and knowledge sharing, followed by a definition of critical knowledge mobilization and examples of historical ideas and everyday tensions in practice. Building on these, we propose the need to advance and shift the culture of KMb, and to embark on engaged research as a means of innovation. We suggest that a reflexive process of critical KMb can facilitate innovation and promote a culture of knowledge mobilization in Canadian social gerontology.
