High Number Of Opioid Overdoses

Windsor-Essex County

Date/Time/Approximate Location

December 15th to December 21st of 2022 


Event Description (What is Happening? Who is Affected?)

The Windsor-Essex County Health Unit’s Opioid and Substance Use Notification System has identified an increase in the number of overdoses and substance-use related Emergency Department (ED) visits and Emergency Medical Service (EMS) calls inclusively between December 15th and December 21st of 2022.

Over this seven-day consecutive period, the system flagged a total of eight (8) opioid overdose ED visits, six (6) of which involved FENTANYL. These values exceed our five-year historical average for the current seven-day period in question between one and two standard deviations above the mean. Alongside the ED visits, the system also flagged thirteen (13) substance-use related EMS calls between December 15th and December 21st, with at least one EMS call per day.

Together, the eight (8) opioid overdoses combined with the thirteen (13) substance-use related EMS calls are values that warrant a public alert.

Partners involved in the WECOSS, including the WECHU, Windsor Regional Hospital, Essex Windsor-EMS, Erie Shores Healthcare, and Police Services, continue to monitor this increase and are working to understand more about these reported cases.
