marijuana-growing operation. It could be the largest indoor growing operation we've uncovered in Grey County to date," said Grey County OPP Cst. Steve Starr. "This certainly, if not the largest, would rival the largest."

More than 5,300 cannabis marijuana plants in various stages of growth were seized. At maturity, they would have a street value exceeding $5 million. Police also seized about 100 pounds of cannabis marijuana bud and 300 pounds of marijuana leaves and stems worth close to $1 million.
