The Canadian Chronic Disease Surveillance System (CCDSS) uses linked administrative data sources from every province and territory to estimate the incidence and prevalence of chronic conditions, and, use of health services and health outcomes. Its aim is to foster the collection of surveillance data in a consistent and comparable way across jurisdictions. Patient privacy is protected since only population-level summaries are shared by the provinces and territories. Tracking health conditions through this approach complements other surveillance data sources, such as surveys and registries, and allows for timely reporting to support the planning and evaluation of policies and programs. The Public Health Agency of Canada used provincial and territorial data to create the Pan-Canadian data, available on this website. Provincial and territorial specific data are accessible on the Agency’s Public Health Infobase: https://health-infobase.canada.ca/ccdss/data-tool/
