MS Windoc was a lake freighter or laker, initially constructed as an ocean-going bulk carrier in West Germany in 1959. Entering service that year as Rhine Ore, the ship was renamed Steelcliffe Hall in 1977 and reconstructed as a laker. In 1988 the laker was renamed Windoc and in 2001, was involved in a collision with a bridge on the Welland Canal which caused the ship to catch fire. The ship was declared a constructive total loss. While undergoing repairs in Ontario, the ship broke free of its moorings and grounded. Later pulled free, the vessel was eventually converted into a barge.
