On Friday, the OPP says its street crime unit seized more than 11,000 cannabis plants from three illegal growing operations.
Two were uncovered in Rideau Lakes and another in Elizabethtown-Kitley, police say.
In all cases, plants were being grown both indoors and outdoors and search warrants were executed, according to police.
Several people are now facing a number of charges.
