The western border is Kipling Avenue, though the part of the neighbourhood west of Islington is sometimes considered a separate area named Beaumonde Heights.
The area remained largely agricultural until after World War II, joining Metropolitan Toronto in 1953.
Presently the corners of Albion and Islington in Thistletown has a large presence of East Indian stores and services.
The village of Thistletown (originally called St Andrew's) was planned for John Grubb (1783-1850) in 1847 around the intersection of Albion Road and Islington Avenue.
Grubb was a promoter of the Albion and the Weston plank toll road companies, an elected member of the Home District Council and a magistrate.
