The original building measured 75 feet, 9 inches, by 114 feet, 2 inches, with a midway and baggage room built under the tracks that measured 156 feet, 8 inches, by 81 feet, 1 inch, and clock tower was 24 feet, 9 inches, square. The clock tower stands 140 feet tall and, estimating from the photographs, the main building is about 50 feet high. Once entered, the building only has one floor with the rails elevated by an embankment that allows passage underneath without having to change floors. Additions in 2003 added a triangular section to the north side of the building that includes more retail space and a loading dock, pushing the west façade tight to the side walk bordering Yonge Street, and also extending the eastern side of the building to include another loading dock. The scale is quite grand and is apparent by the 38 foot high ceiling as one enters into what once was the main waiting area. The public areas are at a large scale that tapers once one circulates to the midway under the tracks, and would have opened up again once one were to move up to the platform, because, at the time of construction the embankment built for the tracks would have been one of the higher points in the vicinity.
