For what it’s worth (setting aside my strong belief that any text needs to be grouped together with the pictogram it’s describing), it’s not immediately obvious to me what the intended hierarchy here is. Assuming all the destinations are necessary to include at this point (I assume two separate roads are named because you can access other roads by heading in another direction, otherwise should just point to street level), grouping destinations together by type (ie transit modes, station amenities, external destinations) would increase the predictability of the sign content throughout the station such that you didn’t have to look for your destination on each subsequent sign, rather it would appear where you expect it from sign to sign. If what you’re looking for isn’t on the sign, you’ll have gone too far. So:
(6) Finch West Line
Buses
Washrooms
Passenger Pickup/Drop off
Parking
Finch Avenue
Four Winds Drive
Also not sure why two arrows are necessary unless this is trying to communicate that the destinations on the second line are a longer walk than the first, in which case the sign should say that/there should be some internal logic exercised, ie setting a threshold for when distance/walk times should be included or separating destinations that require vertical access versus those that do not. The use of the international symbol of access to indicate the accessible path doesn’t consider that someone who has a stroller, luggage, a temporary injury etc likely doesn’t associate themselves with wheelchair users and therefore it’s not immediately intuitive what is being indicated. Ideally it would just point to the elevator, and you can make an individual decision whether you need it or if you’re comfortable taking the stairs.
