Canadian Longitudinal Study on Aging (CLSA)

Canada is experiencing an unprecedented change in the make-up of its population. By 2036, nearly one in four Canadians will be age 65 or older. With rapid demographic change now underway, there is a critical need for high-quality research on aging as well as strong evidence to support the enhancement of programs, services, policies and care.

The Canadian Longitudinal Study on Aging (CLSA) was established to enable research that moves beyond a snapshot of the adult population to understand and observe the complex interplay between physical, social and psychological determinants of health over time.

The overall aims of the CLSA are:

  • To examine aging as a dynamic process
  • To investigate the inter-relationship among intrinsic and extrinsic factors from midlife to older age
  • To capture the transitions, trajectories and profiles of aging: successful aging
  • To provide infrastructure and build capacity for sustained high quality research on aging in Canada
