High Quality Content by WIKIPEDIA articles! Toronto Harbour or Toronto Bay is a bay on the north shore of Lake Ontario, in Toronto, Ontario, Canada. It is a natural harbour, protected from Lake Ontario waves by the Toronto Islands. It is a commercial port on the Great Lakes as well as a recreational harbour. Waterfront uses include shipping, residential, recreational and cultural. Toronto Harbour is both a commercial port and a recreation area. Commercial activities are confined mainly to the harbour's eastern side, while the western side was developed into Harbourfront, a conversion from industrial land to recreational and cultural uses. Harbourfront has parks, hotels, an amphitheatre, and many other facilities. The Toronto Islands are also mostly recreational, although they do also contain a small community and an airport.
