Southlake Regional Health Centre (formerly York County Hospital) is a hospital located in Newmarket, Ontario, Canada.
A private hospital was founded in 1932 and on August 22 the province granted a Charter of Incorporation for the York County Hospital Corporation. In 1924, it became a public hospital. In 1946, the Margaret Johnson Davis Wing opened with 55 beds. In 1956, the South Wing opened and a six storey tower opened in 1964. Capacity was increased to 420 beds with the opening of the East Wing in 1976. In 1999, a project to further expand the hospital was started. In 1999, the name of the hospital was changed from York County Hospital to Southlake Regional Health Centre. In 2006, a new parking lot was added to across the street from the hospital and a walkway is currently being constructed from this parking lot to the hospital.
