When the PSCR was taken over by Booth, the original intention was to have its terminus at Parry Sound. However, the high prices demanded by local landowners prompted him to choose a location on nearby Parry Island, which would become Depot Harbour. When completed, Depot Harbour became one of the most prominent ports on the Great Lakes, rivalling Collingwood, Midland and Owen Sound. It was the shortest route for shipping grain to the Atlantic, with trains arriving and departing every twenty minutes.
