Sable Island is a small Canadian island situated 300 km (190 mi) southeast of Halifax, Nova Scotia, and about 175 km (109 mi) southeast of the closest point of mainland Nova Scotia in the North Atlantic Ocean. The island is staffed year round by three federal government staff, rising during summer months when research projects and tourism increase. 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.

Halifax is the capital and most populous municipality of the Canadian province of Nova Scotia, and the most populous municipality in Atlantic Canada. As of 2022, it is estimated that the population of the Halifax CMA was 480,582, with 348,634 people in its urban area. The regional municipality consists of four former municipalities that were amalgamated in 1996: Halifax, Dartmouth, Bedford, and Halifax County.
