Hypertension is a common and serious health problem among Canadians, and tracking hypertension leads to understanding how the condition can be prevented and treated. The Report from the Canadian Chronic Disease Surveillance System: Hypertension in Canada, 2010 provides a current and comprehensive picture of hypertension in Canada. Written in collaboration with the provincial and territorial governments, it is the Public Health Agency of Canada's first national surveillance report on hypertension from the Canadian Chronic Disease Surveillance System (CCDSS), which was initially used to track diabetes.
