Route 31 was created in 2007 along with the cancellation of the 206 - Burnhamthorpe Express, the introduction of the 110 - University Express, and the redesign of the 26 - Burnhamthorpe and 13 - Glen Erin. Specifically, the 31 took over parts of what the 13 and 26B used to serve. In 2011, Sunday service on the 31 was cancelled and partially replaced by a rerouted 29 - Park Royal, which serves Homelands but not Folkway. The same happened in 2015 on Saturdays and in 2016 on weekdays, spelling the end of this route and of service to Folkway in general.
