The L.P. Fisher Memorial Hospital opened in 1911, replacing the Carleton County Hospital in Woodstock, New Brunswick. When the hospital’s benefactor, Lewis Peter Fisher, died in 1905, he left a building, $10, 000 for capital changes, and a $20, 000 trust fund to cover maintenance costs of a hospital. All these bequests were to be made after his wife Mary’s death. When she died in 1910, the directors of the Carleton County Hospital inherited the Fisher family house. The governing board of the L.P. Fisher Memorial Hospital was formed and consisted of four trustees and three other individuals determined by the directors, the warden of Carleton County, and the mayor of Woodstock.

The L.P. Fisher Memorial Hospital allowed free admittance of all deserving poor. Renovations were made to the structure including the wiring and plumbing. The first floor contained the business office, men's and women’s wards, kitchen, operating room, and labor and case rooms. The second floor held eleven beds for patients and the third floor was the matron's and nurses’ quarters. In 1913, the hospital purchased its first x-ray equipment and, in 1915, purchased the first wheelchair. In 1926, the hospital purchased the residence of Mrs. T. I. Duncan to use as a nurses’ home. As the years passed, the hospital became inadequate to meet the needs of the people and standards set by the New Brunswick Hospital Act, the Canadian Hospital Association, and other agencies. The L.P. Fisher Memorial Hospital was torn down in 1954 to allow for the construction of a new hospital in Carleton County.
