Bluewater Health is a hospital in Sarnia, Ontario. It was opened October 3, 1896 as Sarnia General Hospital and was the community's first public hospital. In 2010, with extensive renovations to the two existing buildings and construction of a third, it was renamed Bluewater Health. With construction and redevelopment completed at a cost of $319 million, the hospital now encompasses about 600,000 square feet (56,000 m2). It employs almost 1,800 staff and physicians, along with over 700 volunteers, and is Sarnia—Lambton's largest public sector employer. It is funded primarily by the Ministry of Health and Long-Term Care, with additional fundraising by Bluewater Health Foundation and Charlotte Eleanor Englehart Hospital foundation. It has 326 beds, 8 operating rooms, an emergency department, and a full spectrum of programs to serve the approximately 125,000 people in the Sarnia-Lambton area.
