Aulds Cove is directly opposite the community of Port Hastings located on Cape Breton Island.
The community is thought to have derived its name from Alexander Auld, an early settler who had grist and saw mills at this location.
[2] In 1955, the Canso Causeway opened, connecting the southern part of Aulds Cove with Port Hastings by road and railway.
As part of this project, new alignments of Nova Scotia Trunk 4 and the Canadian National Railway (CNR) were built through the community.
Several motels, gas stations, and restaurants have opened in the last few decades and today Aulds Cove primarily serves as a service centre for motorists on Highway 104.
