Suspect Drug-Related and Drug Toxicity Deaths in Ontario

The Office of the Chief Coroner (OCC) for Ontario provides death investigations and inquests to ensure that no death will be overlooked, concealed or ignored. This includes updated summaries of suspect-drug related deaths by public health unit (PHU) region and provincially to provide an early signal of potential trends in suspect drug-related deaths and preliminary data on opioid-related deaths at provincial and public health unit levels.

There were 272 suspect drug-related deaths reported in January 2024 in Ontario. Over the past three months (November 2023 – January 2024), there were 860 suspect-drug related deaths. This represents:

  • A 2% increase from the three months prior (August 2023 – October 2023)
  • A 15% decrease from the same time period two years ago (November 2021 – January 2022)
  • A 31% increase from the same time period four years ago (November 2019 – January 2020)

This information can be used to generate recommendations to help improve public safety and prevent deaths in similar circumstances, and can be shared as needed to support coordination and response activities.
