well i called for 10 but 12 way to many..https://www.thestar.com/news/gta/2018/10/20/digging-deep-a-look-at-the-well-and-the-massive-hole-at-spadina-and-front.html
Up to 12 cranes, according to this article
In some of the previous pages in this thread have the dirt going to a few places. The Lower Donlands lake filling is one and one I believe is up north outside the city. You will have to go back maybe to page 80 or earlier to find the exact places other members have said.Anyone know where all the dirt from that massive hole went to? That’s enough earth to build a small island in the lake.
As was also previously mentioned, mildly contaminated earth excavated the site went to the GFL soil remediation facility in the Portlands for processing (not for lake filling) while the most severely contaminated soil, from the north-west corner of the site was trucked to Montreal for remediation.I believe the exact locations mentioned were the Portlands lake filling and the Greenbank Airport north of Port Perry - but there are apparently also other sites that haven't been named.
