Advance care planning (ACP) is commonly recommended for persons living with dementia. Increasing age and uncertain disease trajectory add complexity to this process. A scoping review of the Canadian literature was completed to assess the feasibility and acceptability of ACP for seniors (≥ 65 years of age) diagnosed with dementia and to provide practice, policy, and research recommendations towards ACP as a critical aspect of care. Twenty-nine articles were grouped into five themes: (1) feasibility of patient engagement in ACP; (2) opinions regarding medical assistance in dying (MAiD) for incompetent patients; (3) knowledge translation to support persons living with dementia, professionals, and caregivers; (4) barriers to and facilitators of the delivery of holistic dementia care; and (5) Indigenous health considerations. Additional research should consider socio-demographic and social/cultural factors associated with older persons living with dementia's engagement in ACP. Future policies warrant a multidisciplinary approach when reviewing legalities. Finally, ACP knowledge translation should become a routine aspect of dementia care.
