Aging and Chronic Diseases: A Profile of Canadian Seniors. This report was developed before the current pandemic and focuses on the health and chronic disease patterns of Canadian seniors. It provides the data and scientific context we need to make evidence-based decisions to address chronic diseases, some of which increase the risk of severe COVID-19, and other challenges to the health of seniors. Going forward, we will monitor the impacts related to the comorbidity of COVID-19 and chronic diseases and other long-term consequences.
