Canada is expecting rapid population aging over the coming decades, a fact that has led many observersto question the sustainability of its pension systems. The effects of population aging, however, could
be mitigated by an extension of the working life. This article presents the results of a critical review of
Canadian knowledge about the determinants of retirement age and labour-market participation of older
workers. The determinants are grouped under ten ‘‘domains’’ covering micro, meso, and macro levels:
labour market, legislation, financial factors, social position, domestic domain, human resource management,
work-related factors, health, work ability, and motivation.
