all of Canada in total tonnage shipped.
- Statistics Canada ranks the port 15th in shipping activity in Ontario.
The makeup of the soil between the mainland and the island varies:
- Stone near the Western Gap
- Mud near the north shore, mouth of the Don River
- Sand near the airport and western parts of the island's north shore
- Clay near the centre of the harbour
Gaasyendietha is Toronto's legendary Loch Ness Monster and it is sometimes spotted in Lake Ontario and even within the Toronto Harbour. The story of Gaasyendietha is a Native Canadian myth from the Seneca tribe.
The original shoreline of the northern shore were low sandy bluffs, just south of today's Front Street. The mouth of the harbour pointed west. Fort York, on the north shore of the bay, near the mouth of Garrison Creek, guarded the harbour's mouth. It was briefly captured by American forces during the War of 1812.
The islands were originally a low sandy peninsula forming the southern limit of the bay. The Scarborough Bluffs are much larger bluffs that lie approximately ten kilometres east of the harbour. Strong lake currents over time washed the sand eroded from the bluffs westwards to form the peninsula surrounding the bay.
The peninsula became the Toronto Islands through the result of two storms and man-made activity. In 1852, a storm created a channel through the eastern edge of the peninsula that formed the south edge of the bay. The storm washed through excavations made for sand for local construction. In 1858, another storm widened the channel and made it permanent.
The eastern shore of the bay, approximately six kilometres east, was a marsh around the mouth of the Don River. In addition to the Don River a number of smaller creeks flowed into the bay. The original site of the town of York had half a dozen short creeks that flowed through it. As the town developed they all became polluted, and were buried. As the city grew the larger creeks, including Russell Creek, Taddle Creek and Garrison Creek, were also filled in.
The town of York was established in 1793 in a ten-block rectangle bounded by the present Front Street, Berkeley, Duke(now Adelaide) and George Street. A government wharf was built to handle the transfer of ships' cargoes. A garrison at the entrance to the harbour, at the mouth of Garrison Creek, was established to guard the harbour along with a blockhouse on the island. In 1801, York became an official port-of-entry for immigrants and cargo. In 1808, the Gibraltar Point lighthouse was built on the island to guide ships.
In the early 19th century, cargoes destined for York would be transferred at Montreal to smaller boats such as Durham boats and batteaux to traverse the rapids of the St. Lawrence River. In 1825, the Lachine Canal was built to bypass the Lachine Rapids. Some of the boats used for cargo were now being built at Toronto Bay. Although not fully established by the War of 1812, the British colonial army was determined to set up boat-building for defense at York. An armed schooner was under construction, when the Americans attacked and the British burned the hull rather than surrender it. The invaders looted the town and destroyed military facilities.
By the time of the establishment of the Town of Toronto, three large wharves existed for shipping, King's Wharf at Peter Street, Cooper's Wharf at Church Street and Merchant's Wharf at Caroline Street (today's Sherbourne Street). The new Queen's Wharf, at the foot of Bathurst Street was constructed in two stages, eventually reaching 244 feet (74 m) in length. Commissioned by the Province of Upper Canada, it cost £4,500. The first harbourmaster of Toronto, Hugh Richardson, was named in 1833. Richardson held the position until 1870. While the Queen's Wharf no longer exists, the Queen's Wharf Lighthouse still exists, eventually moved to a location off today's Lake Shore Boulevard in 1929. In 1849, the Harbour Trust was formed to manage the port and the Queen's Wharf.
In 1832, the Gooderham and Worts Distillery went into operation, using a windmill on the waterfront, near the Don R
