 The first proposal would see Route 512 extended west along St. Clair Avenue West to Runnymede Road, and south underneath the Canadian Pacific Railway Galt Subdivision line to a bus loop at Runnymede Road and Dundas Street West, replacing a portion of route 71A Runnymede.Streetcar tracks would then be extended southeast along Dundas Street West to Dundas West Station where the 504 King and 505 Dundas streetcar routes currently terminate.The tracks on Dundas would be served by a new route replacing the current 40 Junction bus route.
