I wonder how much sense this actually makes. You're digging a new launch shaft deep underground (Don Mills is really deep), and spending a ton of money on new TBMs... just to dig a 2km long extension? It will be far more cost effective just to keep the TBMs running and get more value out of the extension.
Possibly.
But that is an additional 5.5km, and probably another 4 stations. That's not a small additional cost.
Suffice to say, I don't see that entire line going in all at once, in the next funding cycle.
