About ICES

Population-based health research that makes a difference

The Institute for Clinical Evaluative Sciences (ICES) leads cutting-edge studies that evaluate health care delivery and outcomes. ICES researchers access a vast and secure array of Ontario’s health-related data, including population-based health surveys, anonymous patient records, as well as clinical and administrative databases. ICES goes to great lengths to protect privacy and is recognized as an international leader in maintaining the privacy and security of health information.

World-class research teams

ICES is a community of research, data and clinical experts. Many ICES scientists are internationally recognized and a number of them are practicing clinicians who understand the everyday challenges of health care delivery. They lead multidisciplinary teams that include expert statisticians and epidemiologists, as well as specialists in knowledge translation and information security, privacy and information technology. The diversity within these teams and their expertise at using ICES’ outstanding array of linked datasets is the foundation of the innovative approach to research at ICES.


ICES research results in an evidence base that is published as atlases, investigative reports and peer-reviewed papers, and is used to guide decision-making and inform changes in health care policy and delivery. Many ICES reports are undertaken to answer specific questions (known as Applied Health Research Questions) posed by health system stakeholders and policy-makers. ICES research and reports influence the design, implementation and evaluation of health policy and the delivery of health care. ICES studies and reports are highly regarded in Canada and abroad.


ICES is an independent not-for-profit corporation, and takes pride in its international reputation as a trusted, impartial and credible source of high quality health and health services research and evidence. ICES receives core funding from the Ontario Ministry of Health and Long-Term Care. ICES faculty and staff have highly successful track records competing for peer-reviewed grants from federal agencies, such as the Canadian Institutes of Health Research, and from provincial as well as international funding bodies.

A growing network across Ontario

ICES Central is located on the campus of Sunnybrook Health Sciences Centre in Toronto. It has physical satellite sites at Queen’s University in Kingston (ICES Queen’s), at the University of Ottawa (ICES uOttawa), at the University of Toronto (ICES UofT), at Western University in London (ICES Western) and at McMaster University (ICES McMaster) in Hamilton. An additional satellite site is in development in Sudbury at Health Sciences North Research Institute in partnership with Laurentian University and the Northern Ontario School of Medicine (ICES North).
