Parry Sound, located on the eastern shore of beautiful Georgian Bay, is the world’s deepest natural freshwater port. It is located on the traditional land of the Anishinaabek (Ojibwe, Pottowattami, and Odawa) people. The town was named by “Captain Henry Bayfield” after Sir William Edward Parry, the Arctic Explorer.
The pristine, open water, known locally as the Big Sound, and renowned worldwide is more than 5 by 6 nautical miles in area, and more than 90 m deep. Parry Sound is a sailing paradise in a spectacular Northern Ontario locale, designated as a UNESCO Biosphere Reserve.
Parry Sound deepwater harbor on landlocked Parry Sound and its position on two transcontinental railroads and the Trans-Canada Highway have fostered the town’s development as a merchandising, distributing, and shipping center for the surrounding lumbering and mining region. A gateway to the Thirty Thousand Islands of Georgian Bay, Parry Sound is a also popular summer resort.
