They may have decided against it because of what befell the Nordheimer exit at St. Clair West:The secondary entrance on the southwest corner seems like such a missed opportunity. To come out the front door you will be walking up the stairs past the level of the Kay Gardiner Beltline, and then once at the top there will be stairs on the outside to go down to the Kay Gardiner Beltline. They could have put in another door on the Beltline and made the path a quick walkway from the apartments on the north side of Eglinton without crossing the street, and with appropriate lighting a walkway into the neighbourhood.
