So was the goal of this building to simply prop up the value of the site before being swallowed up for the Ontario Line project?

Thanks all. The trees are all gone. I walk along the Don trail and it goes through these areas and couldn't figure out what they were working on, as no real estate signage whatsoever. I'll try to snag some pics next time I'm down there.

Can someone please let me know what is being constructed here? I can't for the life of me find any info anywhere. They started leveling the ground last fall/over the winter and now lots of machinery on site.
