Schooners and fishing boats were also built for the inshore and banks fishery by firms such as the noted boatbuilder H.W. Embree and Sons. The port further developed in the 19th century when railway connections arrived. The construction of the Canso Causeway increased the shelter capacity of the deepwater port leading to further growth in shipping of bulk commodities and the establishment of several heavy industries such as the pulp mill.
