Launched at Collingwood in 1909, the Hamonic  became part of the Northern Navigation Division of Canada Steamship Lines in 1913.  The Hamonic  was a well-appointed passenger ship with many facilities, including a barbershop, music room, ballroom and dining salon with large windows for viewing the passing scenes.  Canada Steamship Lines ran 7-day passenger cruises on the Hamonic, from Detroit to Duluth, including a stop at Sarnia.

On July 17, 1945, while docked at Point Edward, the Hamonic caught fire when flames spread from a nearby work shed.  A quick-thinking crane operator lifted 50 passengers to safety.  Of the 400 passengers and crew the Hamonic carried, one life was lost to the fire.
