The Toronto Islands — historically referred to as Mnisiing, meaning "on the islands," by the Michi Saagiig Anishinaabeg, and formerly referred to as Aiionwatha or Hiawatha's Island by early European settlers — are a chain of 15 small islands in Lake Ontario, south of mainland Toronto, Ontario, Canada. Comprising the only group of islands in the western part of Lake Ontario, the Toronto Islands are located just offshore from the city's downtown area, provide shelter for Toronto Harbour, and separate Toronto from the rest of Lake Ontario. The islands are home to the Toronto Island Park, the Billy Bishop Toronto City Airport, several yacht clubs, Centreville Amusement Park, a residential area, and several beaches. The island community is considered to be the largest urban car-free community in North America, although some service vehicles are permitted. Access to the Islands is by ferry, including the City of Toronto ferries operating from Jack Layton Ferry Terminal at the foot of Bay Street, or by water taxis.
The Toronto Islands are a popular recreation destination. Recreational bicyclists are accommodated on the ferries. Bicycles can be rented at Centre Island. Canoes, kayaks and paddle boats can also be rented on the island. A disc golf course exists on the island. The main beach is along the south shore and the beach on the west shore is clothing-optional. There is ample parkland suitable for picnicking, several playgrounds, water play areas and several gardens.
