There are multiple agencies with signage within Union, Metrolinx being a major one in their areas. And TTC in their subway area, VIA in their Departure Hall.

MX only has control over signage on the platforms. Signage in the concourses and elsewhere in the rail station are controlled by the City. City-owned signage is designed by Entro. VIA does not manage any permanent signage.

Clarifying wayfinding signage to redirect passengers from the TTC moat would be under the City's jurisdiction. MX does not own that area, and therefore, cannot place signage there.

Thanks for clarifying Redesign. I'd heard from others some incorrect info...
