Four years after the adoption of the first Governmental Action Plan to Counter Elder Abuse, older adult bullying in Quebec has emerged as a new government priority. This article is in response to our paper on older adult bullying published in the framework of a public consultation on the subject. It aims to deepen the theoretical and conceptual reflection that was then initiated between the concepts of mistreatment and older adult bullying in order to clearly distinguish them. This reflective process proposes a definition of older adult bullying, as well as a conceptual mapping of the dynamics of these situations.
