Sable Island is a small, remote island off the coast of Nova Scotia, Canada. Sable Island is located in the North Atlantic Ocean, about 300 kilometres southeast of Halifax, and about 175 kilometres (95 nmi) southeast of the closest point of mainland Nova Scotia. The island is staffed year-round by employees of Canada's National Parks agency, Parks Canada. The number of people on Sable Island at a given time fluctuates throughout the year, with this number rising during the summer months when the island is frequented by researchers and an increased staff complement. Notable for its role in early Canadian history and the Sable Island horse, the island is protected and managed by Parks Canada, which must grant permission prior to any visit. Sable Island is part of District 7 of the Halifax Regional Municipality in Nova Scotia. The island is also a protected National Park Reserve and an Important Bird Area.
