King's Mill, Toronto, was a land lot (or land tract) with a 1,100 acres timber reserve established in 1793 by John Graves Simcoe to supply wood to build ships, material for government buildings in York (including Old Fort York).
[1] The reserve was bounded by Bloor Street, Humber River, The Queensway and Royal York Road.
Shipbuilding of vessels on the Humber was not profitable and soon the mill became derelict.
[2] Fisher retained rights to the Mill[3] until the government leased to miller William Gamble in 1834.
[1] The northeast corner of the reserve was operating as a waste dump (Upper and Lower Riverwood Landfills from 1959 to 1964)[6][7] today the site of the saw mill is home to King's Mill Park.,[1] as well some commercial and residential use.
