In 1991, the Toronto Transit Commission came under pressure as the result of a sharp recession pushing down provincial and municipal budgets as well as ridership, and the Commission experimented with a number of routes designed to maintain particular services while saving resources. With ridership too low to justify Monday-to-Friday evening and Saturday daytime service on the 122 GRAYDON HALL route, the TTC established the 166 SILVER HILLS - GRAYDON HALL route to maintain service in the Duncanmill, Graydon Hall area while sacrificing the direct connection to the YONGE SUBWAY at York Mills station. In addition, Monday-to-Friday evening and Saturday daytime service was added to the portion of the 115 SILVER HILLS that was not duplicated by service on 95 YORK MILLS.

A similar approach was taken in the Calvington area with 164 CALVINGTON-RUSTIC ROAD. As the recession progressed and budget cuts increased, however, both experiments proved unsuccessful.

Service initially provided during Monday-Friday evenings and Saturdays at thirty minute intervals. The route operates from Eglinton Garage.
