Partridge Island Quarantine Station

The Partridge Island quarantine station was designated a national historic site of Canada in 1974 because of the significant role it played in immigration to Canada, and more specifically to the Maritime Provinces, in the 19th century.


The heritage value of Partridge Island Quarantine Station National Historic Site of Canada lies in its historic role as a 19th-century quarantine station as illustrated by the site, setting and landscape of the island and the quarantine-related remains it contains. Partridge Island was one of two major quarantine stations in 19th-century Canada. 

Established in 1830 to protect Canadian citizens from contagious diseases carried by in-coming ships, the station provided treatment for immigrants and crew members who were ill, as well as purification facilities for the healthy passengers aboard the ships. This station was active during a particularly early and busy period of Canadian immigration. During 1847, 2000 Irish immigrants fleeing from the potato famine were quarantined here during a typhus epidemic. 601 of them are buried in a mass grave on the island. Passengers quarantined on this island eventually settled in New Brunswick, Upper Canada and the United States.


Partridge Island continued to be used as a quarantine station until 1941. It was occupied for the military defence of Saint John during both World Wars, and also used as a light station. All buildings on the island were demolished in 1955 and 1998-1999. Today the site contains remnants of buildings and structures associated with its important role as a 19th-century quarantine station, including those of the doctor’s residence (built ca. 1872), the 2nd class immigrants, marine officers’ and smallpox hospitals (1899-1901), a low water wharf, and a cemetery containing graves from the 1847 typhus epidemic.
