National Surveillance of Opioid-related Harms Published: ()
Canada continues to experience a serious and growing opioid crisis. Across the country, it is having devastating effects on families and communities. The Government of Canada works closely with the provinces and territories to collect and share data to monitor opioid-related harms, including mortality data.
Emergency Medical Services (EMS) Data
To obtain a more complete picture of the crisis, Emergency Medical Services (EMS) information is being presented at the national level to examine suspected opioid-related overdoses occurring in pre-hospital settings.
EMS data include information documented by EMS providers generally in the form of electronic or written reports. In this second quarterly release, EMS data on suspected opioid-related overdoses were available from seven jurisdictions across Canada: Yukon (Whitehorse), Northwest Territories (Yellowknife), British Columbia, Alberta (Edmonton and Calgary), Manitoba, New Brunswick, and Newfoundland and Labrador.
The Government of Canada in collaboration with provinces and territories will continue to coordinate efforts to present a more complete, national picture of suspected opioid-related overdoses involving EMS responses in subsequent reports.
Why are EMS data important?
EMS providers are typically the first health care workers who respond to opioid overdose emergencies occurring in pre-hospital settings. Having access to such timely data will help to identify populations who may be at risk and to inform the development of public health interventions and policies at all levels of government.
What did we learn from data on administration of naloxone by EMS?
Naloxone is a medication that can help reverse the effects of opioids. Based on data available among jurisdictionsFootnote 1 reporting data for naloxone administrations by EMS providers, main findings show that:
- 2 out of 3 suspected opioid-related overdoses occurred among males
- Suspected opioid related overdoses were most common among individuals between the ages of 20 and 29 years

Please note: As case definitions vary across jurisdictions, data should not be compared across jurisdictions. Cities have been enlarged for better data visualization and user interactivity. Suppressed: data has been suppressed due to small counts.
