For whatever reason the TTC uses slippery surfaces at all of their stations to help people fall down the stairs and break a bunch of bones. And I even after rebuilding them decides to use the same slippery tiles.
No logic to it whatsoever.
I'm with
@T3G for this being a rather tangential thought to the topic at hand; but I would then add, its also nonsense.
The TTC is rebuilding their staircases with anti-slip granite edging. It doesn't provide unlimited traction, particularly when wet, but its pretty good; for those not comfortable enough there are railings and soon, every station will have elevators.
The idea that the TTC is engaged in negligent staircase design is bizarre; any such contention should be supported by evidence, citations please.

The stairs will be finished with granite tile in a dark grey colour contrasting the non-slip tread edges in a light grey colour to aid visual
differentiation. Tactile tile will be added at the top landings as per TTC standards
