The golden years are not all golden in the growing number of Canadian communities with high concentrations of older people, many of whom struggle with health, transportation and dementia care challenges.

There are now 111 urban centres where at least a quarter of residents are 65 or older, according to a new analysis by the Local News Data Hub at Toronto Metropolitan University (TMU). The analysis, which ranked communities based on the percentage of older residents, focused on places with at least 10,000 people because that loosely aligns with what Statistics Canada considers the minimum population for an urban centre.
