Event Description

The Windsor-Essex County Health Unit’s surveillance and monitoring system has identified an increase in opioid-related Emergency Department (ED) visits and Emergency Medical Service (EMS) calls inclusively between September 27th and October 3rd of 2021.

Over this consecutive seven-day period, it has been identified that there were ten (10) fentanyl overdoses, nine (9) of which were reported by Windsor Regional Hospital and one (1) of which was reported by Erie Shores Healthcare. Historically, the number of overdoses reported during this period are significantly high when compared to our two-year and five-year averages. Based on the information available, a public alert is strongly warranted.

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.


Please share this information with clients and relevant partners. If you are aware of any linkages between these cases or other causes for these increases, please contact the Windsor-Essex County Health Unit.
