Chronic diseases are the leading cause of death in Ontario. Ontario Health works in partnership with the public health system to use evidence-informed approaches to promote health, prevent diseases and improve the health of the entire population, including equity-deserving and Indigenous populations. This work includes coordinating programs and services that address modifiable risk factors and exposures, early detection and screening as well as publishing reports with evidence-based recommendations and actions to prevent chronic disease for a healthier Ontario.
