, made up the shorelines of
Lake Iroquois, a glacial lake that preceded
Lake Ontario. Lake Ontario is a recent lake. As the last
glaciation, the
Laurentian glaciation receded, a number of
proglacial lakes filled in basins adjacent to the glacier. One of those
proglacial lakes was
Lake Iroquois. Lake Iroquois was considerably deeper than Lake Ontario, as a lobe of the
Laurentian glacier still filled the valley of what is now the
St. Lawrence River. The southern boundary of Lake Iroquois was the Niagara escarpment. The lake flowed over the
Niagara Escarpment east of Rochester, and flowed to the
Atlantic Ocean down what is now the
Mohawk River, to the
Hudson River. The shoreline of Lake Iroquois can be observed in steep hills, such as that on the north side of
Davenport Road.
Casa Loma has a view of the harbour, four kilometres away, as it is on the height of the old shoreline. When the glacier retreated from the St. Lawrence Valley, the shoreline receded to a much shallower level than today's lake, as it takes time for land that had been under a heavy glacier to rebound. This lake was called
Admiralty Lake. Some sources suggest the drainage of the lake triggered the
Upper Dryas climatic change. Some sources suggest the lake drained all the way to
sea level and the lake became
brackish. Since the last
ice age, silt deposits, borne mostly from the erosion of the
Scarborough Bluffs and the
eluvial rivers to the east were swept by strong, natural Lake Ontario currents creating prominent fingers of land away from the lakeshore in the current central waterfront area, including the
Toronto Islands. The shore of Lake Ontario (at least within present-day
Toronto Harbour) is mostly landfill, extending a kilometre or more from the natural shoreline. , located close to where Toronto's original shoreline was. Due to
land reclamation projects in the late-19th to early-20th century, the original shoreline is now located inland. Adding to the existing silt deposits,
Ashbridges Bay was filled in and the
Port Lands area (Cherry Street to Leslie Street) was created in the early 1900s. The bay was filled in partly due to concerns about public health – locals had disposed of sewage, farm animal carcasses and household waste in the bay for years. During this period, the
Don River, which used to flow into the bay to the south-west, was diverted (straightened) toward the harbour, first directly southward and later westward through the current configuration of the
Keating Channel. Currently, there are proposals to restore the original natural watercourse of the Don, which would bring it closer to the downtown core. The modern harbour area was mostly formed through landfill in the years around the
First World War, to allow for deeper container vessel wharf access. The central waterfront functioned as an important industrial area for many years, providing shipping access to communities from
Port Union in the east to
Mimico in the west. Toronto expanded along the waterfront with new residential suburbs. West of the
Humber River, outside the city limits, the waterfront has been mainly private lands fronting on the lake. East of the Humber River, within the city limits, the waterfront is under the control of the government. The
Sunnyside lakefront from the Humber east to Jameson was filled in, creating new lands for recreational and park land uses. To the east of Sunnyside, the lands were originally military grounds, centred on
Fort York. The Garrison lands became the Exhibition grounds and have been public ever since. To the east of the harbour area, parklands were built along the waterfront from
Ashbridges Bay east to the eastern city border at Victoria Park. Further east, the Scarborough lands have been dominated by the
Scarborough Bluffs and development could not proceed to the waterfront. in the 1963. The highway substantially changed the western portion of the waterfront. In the 1950s, the
Gardiner Expressway project, connecting suburbs to the west, substantially changed the western waterfront. As the Toronto area prospered and the downtown lands became more developed, industry began to move out of the central area seeking cheaper land in the suburbs. This left behind many heavily polluted sites (some of the main uses of the waterfront were oil and coal storage, waste disposal and incineration, and heavy manufacturing especially in Toronto harbour). The railway lands just to the north of the waterfront now became too valuable to keep industrial and have been converted to other uses, starting with the
CN Tower in the 1970s. The railway lands became the site of the SkyDome (now
Rogers Centre), the
Toronto Convention Centre, office buildings and numerous condominium residential buildings. Tonnage to the Toronto Port has declined over the past 50 years, replaced by increases in other modes of transportation. The Toronto Harbour Commission was eventually dissolved, its lands transferred to the City except for those specifically to be controlled by the successor
Toronto Port Authority, which retained authority over transportation uses in the Port, including the
Island Airport. The federal government created the authority along with others around Canada to manage ports in a more business-like fashion. Following its mandate, the Port Authority has made attempts to increase usage of the Port, initiating a Ship Terminal and Ferry Service to
Rochester, a container facility in the Port lands and plans to expand the usage of the Island Airport, although expanded use of the Island Airport is opposed by local residents and organizations, and puts it at odds with the current City of Toronto council. The
1972 Canadian election saw a further step in the conversion of the central waterfront away from industrial uses. The
Federal Liberals promised to improve Toronto's waterfront, expropriating the area from
Bathurst Street to York Street along the waterfront for the "Harbourfront" project. Some buildings, such as
Queen's Quay Terminal and
Harbourfront Centre were remodeled, and others such as
Maple Leaf Mills Silos demolished and replaced by new structures. The areas south of Queens Quay have been changed mainly to cultural and recreational uses and the area north of
Queens Quay has been redeveloped into condominium residential towers. West of Bathurst Street, the lands have been converted into a new residential area. The area between York Street and
Jarvis Street along the water has remained in private ownership except for the
Jack Layton Ferry Terminal. Residential condominiums and the large Harbour Castle hotel were built along the water and the
Toronto Star built a new headquarters office building at Yonge Street. The Redpath Sugar Factory remains, and several industrial buildings have been converted into other uses. The area along the water has been primarily owned by the Toronto Harbour Commission, and eventually transferred to the City's Economic Commission. In 1988, Prime Minister
Brian Mulroney called another Royal Commission into the waterfront that was headed by former mayor
David Crombie. It was reported in 1992 with a detailed, but expensive plan of environmentally sound development following on the heels of his 1982–86 Toronto Waterfront Regeneration Trust Commission report. Few, if any of the recommendations were carried out, as had been the case during the previous 60 years. Toronto's bids for the 1996 and 2008
Summer Olympics saw plans for much of the new facilities to be located along the waterfront, with all three levels of government committed to spending a great deal of money if the games were won, but on both attempts Toronto lost its bid due to the lack of diversity in facilities either planned or in situ and, except for further commercial condominium development at
Harbourfront offering grandiose views of the water, the waterfront was unchanged. The recent bid by Toronto for the
World's Fair 2015 also planned to use waterfront sites to accommodate the fair, but this bid also failed. As of 2008, most of the lands to the east of Yonge Street, around and east of the Don River are slated for redevelopment directed by the Toronto Waterfront Revitalization Corporation. Plans are to build predominantly low-rise developments, with a waterfront opened up to public uses, including recreation. The Don River, diverted into a channel is slated to become 'naturalized' with more natural river banks and a more natural appearance.
