Opioid toxicity
We use this information to alert partners and stakeholders and help inform effective responses and service delivery to residents.
We are also working with partners to develop an Opioid Strategy for Peel. The goal is to ensure we are collaborating on initiatives to prevent and reduce harms related to opioid use in the region.
The information reported on this page is updated quarterly.
