Conestoga was an iron-clad wooden steam freighter constructed in 1878. In 1922, Conestoga caught fire at Cardinal, Ontario and sank

The freighter was built in Cleveland, Ohio by Quale & Son for the Anchor Line of Erie, Pennsylvania. The vessel was launched on July 6, 1878. On May 22, 1922, while awaiting passage through the Galop Canal Lock 28 (Old Galop Canal), a fire started in Conestoga's engine room. The ship was flushed away from the lock and drifted downstream, where it burned to its waterline and sank. There was no loss of life and its cargo of 30,000 bushels of wheat was salvaged.
