Irving Shipbuilding has secured two new work contracts for its repair yard in Shelburne. The company says it will rehire many of the workers who were temporarily laid-off in November. A National Defence firefighting tug and a Canadian Coast Guard vessel will arrive in the ship yard for repairs next week. The two projects will provide enough work for roughly 15 weeks. Irving says 16 employees have already been recalled while dozens more will return to work in the coming weeks. The company was forced to temporarily lay off 48 workers last month due to a lack of work.
