The pilot for Toronto’s Drug Checking Service, which checked and publicly reported on more than 10,000 samples between October 10, 2019, and June 30, 2023, was coordinated by the CDPE. While Toronto’s Drug Checking Service now operates from its own unit within MAP Centre for Urban Health Solutions at St. Michael’s Hospital, a site of Unity Health Toronto, the CDPE continues to work collaboratively with and conduct scientific research on the program.
