Cannabis is legal to buy in Ontario, but there still is an illegal element that exists.
Provincial Police say they seized over $143 million in pot from 52 large-scale illegal operations around the province this summer.
More than 122,000 cannabis plants were seized, with 7,000 coming from one site alone.
Detective Inspector Jim Walker says some were found in rural parts, including agricultural land, former farms or greenhouse facilities.
Walker adds some of these operations are used to fund other illegal activity such as the production of harder illegal drugs and human trafficking.
He notes says those buying the illegal variety may be getting more than what they bargain for.
“We took a number of our seized products from operations previously and sent them away for independent testing and they are coming back with high levels of pesticides but there also coming back as lower THC’s.”
