The Canadian Longitudinal Study on Aging (CLSA) is a large, national, long-term study. The aim of the CLSA is to find ways to help us live long and live well, and understand why some people age in healthy fashion while others do not.

Between 2010 and 2015, the CLSA recruited and collected information from more than 50,000 individuals. The CLSA is a longitudinal design, meaning that it will follow people over a long period of time. However, researchers will not wait years before results are generated.
