Dozens of people have been charged in Ontario and Manitoba as part of a drug trafficking investigation targeting a distribution network between Kenora and Winnipeg.

Ten search warrants were executed in Kenora, Wauzhushk Onigum (Rat Portage) First Nation, and Winnipeg this week, leading authorities to charge 38 individuals with 174 drug-related and criminal code offences.

The charges stem from a lengthy covert investigation conducted by the Ontario Provincial Police, RCMP, Treaty 3 Police Service, Dryden Police Service and Anishinabek Police Service.

Authorities say they seized or purchased $236,563 worth of cocaine, marijuana, morphine pills and heroin over the course of the investigation.

They also seized  $18,385 in Canadian currency and property, including four motor vehicles.

Police say an undercover component of their investigation centred on drug trafficking operations in Kenora. It focused on disrupting a drug distribution network that was being operated from Winnipeg and was supplying Kenora with illegal drugs.

OPP Detective Inspector Chris Harkins says the investigation is not yet complete. He told CBC News "We've identified other criminal organizations that will lead to further investigations into Manitoba with our policing partners."
