HALIFAX -- An iconic lighthouse standing at the mouth of Nova Scotia’s Halifax Harbour is at risk of going silent forever. The Chebucto Head lighthouse has been sounding the alarm for sailors and fishermen for more than 100 years, but its foghorn went silent in February and has not yet been deemed necessary to repair. "At this time there are no plans to reactivate the fog signal," said Harvey Vardy, regional director of Atlantic Navigational Programs at the Canadian Coast Guard. The lighthouse was first lit in 1872 and, until February, its foghorn guided ships from their journey across the Atlantic Ocean. The lighthouse is also a well-known landmark among locals and visitors along the Duncans Cove hiking trail.
