We present the development of a regional dementia strategy in Southwestern Ontario, Canada. We worked with stakeholders in a regional health authority to develop a dementia strategy. We conducted interviews with persons with dementia and their care partners (n = 26) and health care administrators and policy makers (n = 33); and administered a priority-setting survey (n = 64). Both participant groups identified provider compassion, professionalism, and care in the early stages of dementia as system strengths. Both groups also highlighted a need for more integration and coordination, a need for more person-centred care, support for care partners, and more flexibility in the provision and receipt of services. The highest-ranked priorities were improving care partner support, improving access to care, and improving system-wide quality. We integrate these strengths, needs, and priorities in a strategic framework, “Whole Person, Whole Journey”. Organizations developing a dementia strategy may use this framework as a springboard for their own work.
