were transferred to the Commission to administer. In 1912, the commission delivered its first plan for the harbour and the waterfront from the Humber River in the west, to Woodbine Avenue to the east. The Commission dredged the harbour to a depth of to match the new Welland Canal. As the city of Toronto grew the northern shore of the bay was further altered by landfill, and has been moved approximately south. After the Esplanade landfill, the second landfill project in 1910 filled the water lots, which extended the shoreline south of today's Lake Shore Boulevard, providing room for the Terminal Warehouse, the Toronto Harbour Commission Building and other facilities along the new Queen's Quay. The final infill on the north shore was in the 1950s, from Yonge Street east to the Don River, providing room for the Redpath Sugar Refinery, the Victory Soy Mills and several marine terminals. In the 1920s, most of the low-lying marsh of Ashbridge's Bay was filled in to create Toronto's inner harbour area (with the small section to the east and the shipping channel the only reminder of the body of water). In the 1930s, the waters of Hanlan's Bay on the western point of the islands were infilled to create the Toronto Island Airport. By the time that the plans to build the St. Lawrence Seaway were announced, commercial usage of the harbour was already in decline. The previous infill on the eastern side created in the 1920s was used to build modern port facilities. In the 1970s, the northern shore was in decline and there was a new political initiative to rebuild the waterfront without industry in a manner seen in other cities. The Harbourfront project expropriated the lands west of York Street. Several facilities were renovated, such as the Terminal Warehouse, and others were demolished, creating space for recreational and cultural uses. The area around Yonge Street remained in private possession and a hotel and condominiums were built on the shoreline. The area east of Yonge Street remained in light industrial use under public possession. On the north side of the harbour, there are a few buildings left from the industrial period. Some are in use, such as the Redpath Sugar Refinery. Others have been demolished or are slated for demolition, including grain storage elevators at the east and west end of the inner harbour. Starting in 1972, the Government of
