'Richview' district (and Richview Sideroad) originated in Westmount at Scarlett Road (at the now Eglinton Avenue intersection) and its elevation in the scenic neighbourhood gave birth to the name 'rich'-'view'.

Richview Sideroad was changed to Eglinton Avenue in 1970 when a 4-lane bridge was built from the east side of the Humber River to Scarlett Road in Etobicoke.

A very large amount of land comprising the majority of farms lots on both banks of the Humber River between Lambton and Weston were first purchased by the Scarlett family in the 19th century.

Much low-density residential was built on former farmland as many immigrants from Italy and some eastern-European countries, settled in the rapidly urbanising Etobicoke during the 1960s.

A large collection of early photographs of Humbervale became one of the largest components of Etobicoke's 'History Room' when it was established in 1985 at Richview Library.
