Organizational Description

The Health Unit officially opened on July 1, 1947 to serve the municipalities of Leeds and Grenville. In 1967, Lanark District joined the organization, which then became the Leeds, Grenville and Lanark District Health Unit (LGLDHU). Learn more about the history of the Health Unit.

The Health Unit covers a 6,329 square km area in Eastern Ontario, with a population density of 25.7 people per km. The southern part of our area borders the St. Lawrence River between Kingston and Cornwall, extending north into the Ottawa Valley. The population of Leeds, Grenville and Lanark is 170,205 people, the majority of whom live in a rural environment (58%).

Our total budget is approximately 12 million dollars, received mainly from the provincial government and local municipalities on a 75:25 cost-shared ratio. We also receive some 100% provincial funding and revenue from other sources, which adds to the base budget. Visit our Map of Municipalities page to view a listing of our local municipalities.

Since we are a service delivery organization, approximately 85% of our budget is for staffing requirements. We have approximately 144 full-time equivalents, filled by highly skilled public health professionals working in a wide range of roles. Visit our Staff section of our website for more information about them.

Staff is distributed throughout 6 sites in the tri-county area; the largest office is located in Brockville and other sites are in Smiths Falls, Kemptville, Almonte, Perth and Gananoque.

The Health Unit is governed by a Board of Health, consisting of 13 members (i.e. 7 municipal representatives and 6 provincial representatives). Visit the Board of Health section of our website.


Public health is focused on the whole population and our work is part of the daily lives of the people we serve in Leeds, Grenville and Lanark. Public health programs and services have made the cars we drive and the food we eat safer; they have protected us from infectious diseases and environmental threats to health. Public health interventions have created healthier environments to support and inform choices about risks, including those related to tobacco, alcohol and other substances. Public health also impacts communities, by developing healthier built environments, responding to public health emergencies, and promoting social conditions that improve health.

Public health priorities are established by the provincial government for all local public health organizations in Ontario, whose legislative mandate comes from the Health Protection and Promotion Act (HPPA). The purpose of the HPPA is to “provide for the organization and delivery of public health programs and services, the prevention of the spread of disease and the promotion and protection of the health of the people of Ontario.”

The Minister of Health and Long-Term Care, under the authority of the HPPA, publishes Standards for Public Health Programs and Services. These standards are the minimum programs and services that all Boards of Health in Ontario must deliver.
