The Keele alignment really does offer the most benefit.
- Avoids service redundancy between Queen and St Clair, by not routing through the Georgetown corridor
- Opens up a gateway to Swansea and southern Etobicoke via what I'd envision would be a massive intermodal station (bus, streetcar, subway, commuter GO train) at Roncesvalles, which also connects to the hospital
- Easiest path to get from Queen to Bloor via High Park versus disrupting streetcar service along Roncy
- Shallow interchange at Bloor that could easily integrate with the mezzanine level of the existing station, western end of the station could be fitted with dual high-speed elevators per platform for easily transferring between lines.
- Best location to service the Junction with a stop. If Dupont/Dundas is chosen, it's a very pedestrian unsafe area by contrast.
- Massive TOD potential at Keele and St Clair (some of this is already occurring)
To illustrate what could be the end game for the DRL, I present the following:
The Trethewey Stn would help alleviate the Jane bus in a big way whisking passengers downtown way before hitting Bloor, or even the Crosstown. And whatever is built along Highway 27 likely has to be grade-separated anyway, so why not an elevated subway via the Weston-Galt and Hwy 27 to meet the Finch West LRT at Humber College? The run time from Humber College to City Centre would likely be only 25 minutes versus the 1 hour time frame it takes today. Just a thought.
