Hidden Harvest : The Rise and Fall of North America’s Biggest Cannabis Grow-Op by Mark Coakley

Mark Coakley lifts the veil in Hidden Harvest on the untold story of a group of criminals — Ontario police would call them “a gang with no name” — whose most famous exploit was turning an abandoned Molson beer factory north of Toronto into a giant indoor jungle of cannabis. The operation produced tens of millions of dollars in profits, and involved gun smuggling, slavery, violence, pornography, and running cocaine and other illegal chemicals. When the grow-op was raided by police in 2003, the massive scale of the operation drew international media attention. The true masterminds behind the operation were not arrested until 2011, and it was only then that the real story behind North America’s biggest grow-op came to light.
