William Allan, JP (c.1770 – July 11, 1853), was a Scottish Canadian banker, businessman and politician.
Allan served as an associated judge at the 1818 trial of several members of the North West Company charged with the murder of Governor Robert Semple after the Battle of Seven Oaks.
During the Types Riot Allan watched from his property immediately east of the printing press, speaking with Stephen Heward.
[3] Allan also served as a director of the Canada Company, which was formed to develop and sell property within the province.
Allan was a friend of the Reverend John Strachan, and his close connections to the Family Compact led to an appointment on the Legislative Council in 1825.
