Due to its congestion, the TTC has had to expand the station. In 1992, it took advantage of building construction over the Yonge–University portion of the station to open it out and widen the platforms. This was the first stage of a plan, known as the Spanish solution, to enable trains to open their doors on both sides: the tracks would next have been slewed outwards within the widened station, and a central platform built between them. The TTC does not intend to proceed with that plan.
