William Gamble (5 August 1805 – 20 March 1881) was a Canadian businessman and pioneer.
His business interests expanded to include a hotel, a distillery and shipping to transport his flour, as well as local crops, to Toronto.
Flood damage by the Humber River in 1850, and the repeal of the British Corn Laws in 1849 (bringing a dramatic fall in the price of his flour) caused his milling business to collapse, but his reputation as a business leader endured and he was active in the foundation of the Bank of Toronto in 1855.
The last remnants of his milling business fell out of his hands in 1862 when his mortgage was foreclosed, leaving him on the cusp of bankruptcy.
[1] He also donated land for the creation of an Anglican church in Islington, St. George's-on-the-Hill, where he served as warden[1] from 1846 to 1848 and from 1851 to 1852.
