Canadian Longitudinal Study on Aging (CLSA)
The CLSA is a national longitudinal study of over 50,000 midlife and older adults living across Canada's 10 provinces. The cohort is comprised of 2 complementary cohorts. Firstly, the Tracking cohort randomly selected from the 10 Canadian provinces, and secondly, the Comprehensive cohort randomly selected due to close proximity to one of the 11 CLSA data collection sites. Various recruitment strategies were utilised, such as from health care registries and landline telephone calls.
