Service begins on a new route combining the old 144 PREMIUM EXPRESS VIA UNDERHILL and 136 PREMIUM EXPRESS VIA WYNFORD routes. Morning southbound trips depart from York Mills and Wynford as two separate branches, just as they did on the old 136 and 144 routes. In the afternoon, however, trips depart from the downtown and run via Wynford to the north end of Concorde Place cul-de-sac, then back south along Concorde Place, west on Concorde Gate, north on the Don Valley Parkway, east on Lawrence and north on Underhill over the old 144 route to York Mills. This route is operated from Wilson garage, and a premium fare continues to be charged.
