Rides on the TTC will be free on Sunday as the service marks the official opening of the Line One subway extension to Vaughan. Transportation Minister Steven Del Duca made the announcement at Sheppard West Station on Saturday morning, saying it that it was only made possible through the ability of the province and the City to work together in a “rapid fashion.” The free service will be in effect from 5 a.m. Sunday until 5 a.m. Monday and will cover the entire TTC network, including buses, streetcars and subways.
