Cities with the oldest median ages in Ontario often serve as popular retirement destinations or established communities with stable, long-term residents. Parry Sound has a median age of 61.2 years.

Communities with older populations face unique planning challenges including healthcare capacity, accessibility, transportation for non-drivers, and maintaining a tax base as the workforce ages. Many are adapting their infrastructure and services to meet these evolving needs.
