operated as a ferry and excursion boat out of Kingston where most of its staterooms on the promenade deck had been removed to make room for sightseers and dancing. With the loss of her cabins, the Hibou was best suited for day use such as the ferry route it shared with the M.S. Normac. On November 16, 1936, the Hibou made her last run on the ferry crossing and returned to Owen Sound, from where it was to take a few more trips to Killarney and Manitoulin Island. It was dangerously late in the navigation season and the only ships of the pool service still in operation were the Hibou and Normac, S.S. Manitou, S.S. Caribou and S.S. Manitoulin having already gone into winter quarters at Owen Sound. Captain Norman McKay took command of the Hibou while her regular captain, James Agnew, moved back to the position of first officer. On its second trip to Killarney on Saturday, November 21, the cargo on board Hibou shifted while she was operating in relatively calm waters, causing her to founder and sink only 10 minutes out of Owen Sound. It is thought that while testing the accuracy of a new compass, Captain McKay had made a sharp turn to the port side, causing the cargo to shift to starboard. The ship listed to starboard, and did not recover. In the ensuing tragedy, not only the Hibou, but seven of the 17-member crew, and Captain McKay himself, were lost. New management The pool agreement between the two navigation companies continued through the 1930s and into the 1940s. The S.S. Manitou served on the Tobermory ferry route from 1937 until 1941 when it was retired, being replaced by Dominion Transportation Company's S.S. Caribou. The S.S. Manitoulin carried on its regular scheduled route from Owen Sound along the "Turkey Trail" of the North Channel; but instead of terminating at Mackinac Island, she continued through the Soo Locks and proceeded to Gargatua Harbour, and Michipicoten. The 1936 pool arrangement between the two companies had been suggested by Ivor Wagner, a director of Booth Fisheries Corporation in Chicago. Wagner purchased the Dominion Transportation Company Limited in 1937 and moved to Owen Sound the following year. In 1944 the outstanding shares of the Owen Sound Transportation Company Limited were acquired by Dominion Transportation Company. Ivor Wagner had managed both firms since 1937, although absent from the area while
