A Durham Regional Police Service (DRPS) operation in downtown Oshawa dubbed Project Atlantis has resulted in over 250 arrests over the course of four months, along with seizures of cocaine, fentanyl, and cash. The probe, which DRPS officers described as “a proactive enforcement and community engagement initiative,” began in April and will continue to operate until the end of 2026. The key focus of the investigation was the sale and distribution of illegal drugs in downtown Oshawa, the release explained. Between April and July DRPS officers made 267 arrests and say they seized around 45 grams of fentanyl, 674 grams of cocaine, 12 grams of crack cocaine, and more than $10,000 in proceeds of crime. Project Atlantis, a proactive enforcement and community engagement initiative, has led to hundreds of arrests, significant drug seizures, and increased police visibility in Downtown Oshawa.
