The west side of the DRL should at least reach as far west as Humber Loop or Roncesvalles and Queen to prevent future Waterfront West and Queensway routes from needing to enter the congested downtown core by providing a transfer to the subway. Since there is no space in the Georgetown corridor for a subway and the Georgetown corridor will provide stops at Bloor, Eglinton, and Weston while the Barrie corridor provides stops at St.Clair, Sheppard West, and near Steeles and both corridors are slated for all-day service I'm not entirely sure a subway in the corridor is required. Once the corridors are electrified there is no reason, especially since GO has designed the Georgetown South corridor for two tracks per route, that GO couldn't eventually provide a frequent urban service making the idea of laying subway tracks in this area completely redundant. For this reason, and planned fare integration, I don't see a need for the DRL to go near the Georgetown corridor. I would send the DRL west to Kipling station, a "Places to Grow" hub with a GO station, and along the way it would provide access to the Waterfront West LRT at Humber Loop, and a Queensway BRT. Queensway west of Kipling and into Mississauga is ideal for BRT because there is very little urbanization potential considering the bridge over the railway tracks, the 427 interchange, and the hydro towers in the middle of the road.
