It's an option, but as you said an expensive one.
The entry/exit grades would have to start just west of Kennedy and east of Fletcher's creek so it would be close to twice as long as the 1.5km long, $214 million dollar Weston 'Tunnel'(more accurately a trench). But there's absolutely no space to do a cut and cover here as with the Weston 'Tunnel'. They'd have to use TBM's and they'd have to go pretty very deep to get under Etobicoke creek and all the other underpasses along the corridor not to mention maintaining the structural integrity of the rail line above it. It may have to take a slightly different route than the corridor itself and who knows how many other physical barriers(utilities, sewage) that might have to be rerouted. The tunnel section would be at least 1.5km long and including the trench section it would be about 2.5km long overall. The other major cost would be underground station itself. A more suitable comparison for such a project would probably be the Eglinton LRT or the YUS extension rather than the Weston grade separation considering the underground station required, a station that will be much larger than those on the metro's. Also this project would be in a much more disruptive location, below a very active passenger & freight rail corridor.
And so the cost for such a project would be more akin to the costs of a subway then the Weston trench. The YUS extension is 2.63 billion for 8.6 km or about $300 million per km. So we're looking at about $500+ for the 1.5km tunnel & the large underground station. Add to that another $100+ or so for the trenches. In all I'd say this thing will run us upwards of $650 million. If I'm in the ballpark with that estimate, I just don't see saving Kitchener folks (the ones heading to Brampton/Mississauga) the inconvenience of transferring being worth 650 mil.

Every other line?
Not even close...
