There's a big one planned for 309 Adelaide Street West. Possibly 50 floors.
That one is referred to as 30 Widmer thread-wise here: http://urbantoronto.ca/forum/showthread.php/18511-30-Widmer-St-amp-313-Adelaide-St-W-(Plaza-51s-)
It is not through approvals yet, so it will be subject to new Ontario Building Code requirements that no more than 40% of the exterior be vision glass. The question with this next set of 40/60 buildings is how much of the exteriors will be spandrel glass. Here's hoping for more interesting and innovative claddings like the Okoskin that will be going up on Nest, the high-quality aluminum going up on Picasso, brick, pre-cast brick of the quality gracing The Florian, pre-cast of the quality gracing One St. Thomas, and other options. Here's hoping that developers can be convinced to do better than spandrel glass more often!
