William Robinson (November 5, 1823 – July 21, 1912) was an Ontario businessman and political figure. He represented Kingston in the Legislative Assembly of Ontario as a Conservative member from 1871 to 1879. Robinson was a Justice of Peace for over forty years, but when the Tories were brought into Toronto in 1905 they relieved him from the post. While in office, he was responsible for exposing the corruption of the City Chamberlain and the Tax Collectors by exposing that a sum reaching nearly $16 000.00 was missing from city accounts.
