Sheppard west extension would help alleviate some of the pressure on the Yonge line. Passengers travelling to the west side of the city will have the option to transfer at Sheppard instead of Bloor.
Sheppard West will be useful for some trips, for example from the north-east to York U, or to places in the west along Lawrence, Wilson, Sheppard etc.
But it will not be of much help for the Yonge line where it matters most: Eglinton to Union. The Spadina branch is 4 km from Yonge at Sheppard, but just about 1 km at University. It does not make sense to go a big detour just to take the Spadina branch into downtown.
Furthermore, the Spadina branch gets very busy south of St George.
