Although your map is a bit off (your line ends @ Albion and Martin Grove instead of Humber College) if a subway line like that went up Albion then followed Finch down to Humber College, you have solved literally all of North Etobicoke's transit problems!
Suddenly intersecting buses along Islington, Kipling, and Martin Grove can dump passengers onto this line rather than continuing down to Bloor or Eglinton...
Also since the road network connectivity sucks because of the Humber River, the subway would actually provide better speeds than driving for people to go from Etobicoke into North York. Also the portion between Weston and Albion can be an outdoor bridge to cross the large valley
If you build this line, then there will never ever be a need for a Finch LRT period. Because it would serve the western end of Finch quite well...
I think it is worth doing a serious study on at least to see what kind of ridership levels this would bring in...
In additon....I can't see the point in building a subway that got that close to Pearson without completing the job! Of course it would mean that after it crossed the valley it would have to route SW instead of NW
