College is getting a second exit and elevators which should help.We're at the point where King and College seriously need a full on strip it to the guts renovation and expansion too. It's no good to increase capacity in to downtown with trains passing through faster and more frequently at Yonge and Bloor going south when they get to those stations and there's literally no space on the platform left for people to exit from the train.
King is getting elevators, but they are being shoehorned into the existing Commerce Court exit.
Both need additional space within and to/from their principal mezzanines.
FWIW, I can tell you that is on the radar, as is an addtional entrance/exit for St. Andrew, and north exit for Dundas. But those projects are not yet in design and much further off.
