The Windsor-Essex County Health Unit’s Opioid and Substance Use Notification System has identified an elevated number of opioid-related Emergency Department (ED) visits and overdoses inclusively between September 5th and September 11th of 2022.

Over this seven-day consecutive period, there were a total of twelve (12) opioid overdoses reported by Windsor Regional Hospital, nine (9) of which involved fentanyl. In addition, there were three (3) opioid non-overdoses reported by Windsor Regional Hospital during this same time period, two (2) of which involved fentanyl. These values exceed both our two and five-year historical averages for the current week in question by more than three standard deviations. As such, based on the information available, a public alert is warranted.
