I did look but wasn't sure about it. There was a flattened out spot of dirt though. In fact, I was thinking maybe they were only going to use one crane for both towers.
I'll swing by again this weekend and have a better look.
The crane was going in today. I walked by on Bloor but didn't get too good a look. It's big and white. Yonge and Bloor is going to look really strange in a month or two....
