The ship was built in 1910/11 by the British shipyard Swan, Hunter & Wigham Richardson for its own account and offered as a toiler . After a successful maiden voyage , she arrived in Montreal on September 21, 1911 and was chartered there by the shipping company James Richardson and Company from Kingston. In 1912 Richardson bought the ship and had it managed by James Playfair from Midland. Since the diesel drive proved to be too weak, the Toiler was fitted with a compound steam engine built in 1882 for the freighter DC Whitney by Dry Dock Engine Works in Detroit at the Kingston Dry Dock Company shipyard as early as 1913 .
After several intermediate sales , the toiler came to Canada Steamship Lines (CSL) from Montreal. In 1919 the ship was renamed Mapleheath and was brought under the Canadian flag around this time. On December 8, 1920, the ship overran its own anchor in the St. Gabriel Lock of the Lachine Canal , tore the bottom open and sank in the lock. The ship was lifted, repaired and put back into motion. In 1929 new triple expansion steam engines were installed. It was not until thirty years later that CSL sold the ship to the McAllister-Pyke salvage company from Kingston, who cut off the forecastle and used the rest as a salvage pontoon with a crane installed.
