'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.
