The Sir Charles Tupper building is also on the Canadian Register of Historic Places.

The Edward Drake building (old CSEC building) is "classified federal heritage building"

The Sir Leonard Tilley Building is "classified federal heritage building"

Bus Shelter in Vincet massey park is "classified federal heritage building"

So there is that to deal with as well....and I know some here love to protect heritage buildings regardless of the context downtown.

That leaves:

1) The CRA building & its parking lots. Along with the parking lots of the RA building ~17 hectares

2) any space gained from re-aligning the interchanges and fixing there issues.

3) The canada post section (the area around the parking garage) of ~20 hectares

4) Random assortment of parking lots like that used for the Sir Charles tupper building.

Probably 30 to 50 hectares worth of space in the end without touching anything zoned EP, O1, or L1. Just keep the current Canada post office tower and rebuild the rest with no above ground parking .

Though hopefully this ends with Vincent massey and hogs back park being recognized as parkland by the city and included in there calcs. (AFAIK its currently not)
