For the record, my vote was other, so here goes.
I would suggest an LRT, underground from Jane to Brentcliffe, then side of the road until going back underground for the Don Mills terminall (fully grade separated all the way, but on surface or elevated when possible). In the west I would elevate the line in the Richview corridor, with airport access to be determined, but leaving room for a shared ROW. The eastern section past Don Mills would be left to a later phase, but likely centre of road ROW as proposed by Transit City, given the ROW available and proximity to Kennedy station or the grade separated part of the line.
While a subway could be elevated in the Richview corridor, this would be a significantly larger structure, and more importantly would make the rest of the suburban LRT network I support more awkward. While I would like to see the subways in Move Toronto (with the above modifications to Eglinton), I also strongly believe in suburban LRT. At a minimum I would have upgrading the Finch, Hwy 27 and Don Mills BRT (which I would reduce below the BRT light proposed to simple limited stop, frequent service buses) lines to LRT included in the 25 year timeline, and Eglinton provides a strong backbone for that network with no loss in service quality west of Don Mills.
