If the times and alignments are still up for debate, I think that Etobicoke would be pretty well served with the Eglinton subway, B-D extension to Sherway, and Jane and Finch LRTs. I'm just worried about duplicating service along the Georgetown corridor that probably won't require two lines. A single, more regional service would probably be all that's needed.
But a DRL to Dundas West would probably be needed in the 15-year timeline. It'd give a good service to CityPlace, and would provide general relief to the King Streetcar. DRL North on Don Mills should be in the 25 year plan just because it's an obvious and very easy extension.
Actually, I used a Wellington alignment for the DRL, and terminated at Spadina (City Place) instead of Union as has been initially proposed. My reasoning for this is 2-fold:
1) It services City Place, as well as the Rogers Centre.
2) It saves from digging up downtown streets twice (after City Place it can use the rail corridor, and thus not require ripping up streets).
And as for the naming thing, I tried to use as much of 'secondary names' as I could (like on the University line, St. Patrick instead of Dundas West, etc).
And I wasn't too sure about the stops for Sheppard West, I didn't know a study existed for it.
