"Is it a super-tall?" It has been mentioned a couple of times in this thread and someone referenced the lowest entrance to the building.

The Council on Tall Buildings and Urban Habitat (CTBUH) does indeed measure total height from "the level of the lowest, significant, open-air, pedestrian entrance to.... (the Architectural Top).

So if the south end of the tower has a pedestrian entrance (presumably not just a fire door lol)... this would explain why @Koops65 has the 300.6 metres height listed on his SSP diagram despite UT's official height of 299m. If there is no door on the south end of the tower .... height fanboy dreams are crushed. 🙃

Toronto may actually have 3 super-talls under construction. 2 are looking fine, 1 tba ...and bound to cause some serious hand-ringing for the next few years.... but does that entrance exist??

The building elevations show a primary entrance well below the measured grade from the architectural drawings:

Grade appears to be measured from the northeast corner of the site. Looking at the survey, grade is about 95.4m ASL:

The southernmost primary door into the building along Yonge Street is conveniently in a retained heritage facade, which means that we can expect the grade of the door to not change over existing conditions. The door according to the survey will be at an elevation of 93.9 ASL:

95.4-93.9 = 1.5m.

The elevations put the building as 299m from grade. The southernmost door is generally 1.5m below measured grade, which makes this 300.5m tall according to CTBUH definitions.
 
Duh... don't know why I didn't just search the CTBUH heights for Toronto. They list Concord Sky at 300.2 metres which still cracks the super-tall barrier.

So whether it's 300.5 metres (@innsertnamehere ), 300.6 metres (@Koops65 ) or 300.2 metres (CTBUH)... Toronto has 3 super-talls under construction.

Height fanboys unite. 🙃

...I think it's pointless exercise trying to squeeze more height from the top by defining what the bottom does, lol. But since we're going there, let's see what the UT jury (ie. @interchange42 , @Paclo ) says about that. <3

Based on the latest architectural plans available (December 2023), the height to the top of the mechanical room is still 299.00 metres. This is measured from the geodetic grade established for the entire site and corresponding to the front doors of the ground floor (95.42m ASL).
