The Toronto Islands are located in Lake Ontario just offshore from the city centre, and provide shelter for Toronto Harbour. The islands are a popular recreational destination, and are home to a small residential community and to the Billy Bishop Toronto City Airport. The islands comprise the largest urban car-free community in North America, though some service vehicles are permitted. Recreational bicyclists are accommodated on the ferries, and bicycles, quadracycles, and canoes can be rented on the islands as well.
