From what I led to believe, a number of culprits entered the site and smashed all the vending machines. They also did $100k worth of damage to the machinery. One of the excavators was damaged while the culprits were joy riding it, and as previously reported the dump truck ended up in the hole which happened to be full of water.
I've reached out to Brookfield Multiplex for an official statement and they haven't responded.
Here's a video from a long time contributor Bernard that shows the incident happening on Sunday.
