The yards was called for by Lieutenant GovernorJohn Graves Simcoe in 1793 and operated from 1798 long before the town of York was populated and up to the War of 1812. The yard was on the western edge of the town and located south of Front Street on the shores of Lake Ontario west of Bay Street. Ships were built along the sand shores using the trees from the forests inland and launched into Toronto Bay. While shipbuilding resumed in York, the naval yards did not build any other navy ships after 1813 and abandoned and likely moved to a safer and more protected location in Kingston Royal Naval Dockyard. The yard built a few ships:
Toronto – schooner 1813 and wrecked 1817
– schooner launched 1812 and renamed HMS Beresford in 1813, as HMS Netley 1814 and finally base ship HMS Niagara; broken up 1843
– incomplete frigate 1813
