According to UrbanToronto, the plans have changed.
1 Yonge will consist of
6 buildings (not 5 buildings) with the
tallest at 88 stories (no longer 98 stories).
The Toronto Star building would see additional floors added, while a
new 40 storey office building would be built on site.
A new 70 storey tower with hotel component has been added as the 6th building.
The remainder of the towers heights are as follows: 75, 80, 80, and 88 storeys.
So we have
88s, 2x80s, 75s, 70s and 40s.
