In March 2018, the Canadian Centre on Substance Use and Addiction (CCSA) hosted two back-to-back events on opioids to provide a comprehensive overview of the crisis and to discuss solutions. The first event, the Law Enforcement Roundtable on the Opioid Crisis, focused on the law enforcement efforts to combat the opioid crisis and will be discussed later in this summary. . . . With support from Public Safety Canada, the Law Enforcement Roundtable on the Opioid Crisis brought together representatives from the Royal Canadian Mounted Police (RCMP), Canada Border Services Agency, provincial and municipal police services, First Nations police, national organizations and academia, as well as senior government officials, to discuss responses to the opioid crisis.
