Opioid- and Stimulant-related Harms in Canada Published:
(December 2023)
: Health Infobase

Context

Canada has seen substantially elevated numbers of opioid-related deaths and other harms since surveillance began in 2016 by the Public Health Agency of Canada. This public health crisis is having a tragic impact on people who use substances, their families, and communities across the country, and is shaped by a wide range of factors. The COVID-19 pandemic may have exacerbated the crisis, as several jurisdictions reported higher rates of fatal overdoses and other harms following the onset of the pandemic.

Presented here are the most recent available data on overdoses and deaths involving opioids and/or stimulants from January 2016 to June 2023 in Canada, where available. Recognizing that harms related to opioids, stimulants, and other substances extend beyond overdoses (poisonings) and deaths, we continue to work with federal, provincial and territorial partners to build a broad understanding of harms and substances involved to better respond to this public health crisis. For more details on additional studies and other products related to the overdose crisis, including a statement from the co-chairs of the Special Advisory Committee (SAC) on the Epidemic of Opioid Overdoses, refer to the Data, surveillance and research page.

Deaths Download mortality report in .pdf format

What: There was a total of 40,642 apparent opioid toxicity deaths between January 2016 and June 2023Footnote 1Footnote 2

  • A total of 3,970 apparent opioid toxicity deaths occurred so far in 2023 (January-June). This is an average of 22 deaths per day.
  • The number of total apparent opioid toxicity deaths in Canada reported so far in 2023 (January-June) was 5% higher compared to the same period in 2022. This is based on preliminary data subject to change as death investigations are completed and reported.

Where: The majority of deaths occurred in British Columbia, Alberta, and Ontario; high rates were also observed within other regions

  • So far in 2023 (January-June), most (89%) of the accidental apparent opioid toxicity deaths in Canada occurred in British Columbia, Alberta, and Ontario.
  • Elevated mortality rates have also been observed in other areas with smaller population sizes.

Who: Most apparent opioid toxicity deaths occurred among young- to middle-aged males

  • Males accounted for the majority of accidental apparent opioid toxicity deaths (72%) so far in 2023 (January-June).
  • For males and for females, the majority of accidental apparent opioid toxicity deaths were among individuals aged 20 to 59 years.

Why: Among other reasons, the toxicity of supply continues to be a major driver of the overdose crisis

  • Of all accidental apparent opioid toxicity deaths so far in 2023 (January-June), 84% involved fentanyl. This percentage has increased by 47% since 2016 when national surveillance began but appears to have stabilized in recent years.
  • Of all accidental apparent opioid toxicity deaths so far in 2023 (January-June), 80% involved opioids that were only non-pharmaceuticalFootnote 3Footnote 4. This percentage has increased by 21% since 2018 when national surveillance began but appears to have stabilized in recent years.

Multi-drug toxicity is a contributing factor to the crisis

  • Available information from eight provinces and territories indicates that almost all (98%) apparent stimulant toxicity deaths so far in 2023 (January-June) were accidental.
  • Just over half (54%) of accidental apparent opioid toxicity deaths so far in 2023 (January-June) also involved a stimulant.
  • Of the accidental apparent stimulant toxicity deaths so far in 2023 (January-June), 81% involved an opioid, 65% involved cocaine, and 55% involved methamphetamines.

Data on apparent opioid and stimulant toxicity deaths are not mutually exclusive. A high proportion of deaths involving a stimulant also involved an opioid. Adding up those values would result in an overestimation of the burden of opioids and stimulants.

Hospitalizations Download hospitalizations report in .pdf format

What: There was a total of 39,435 opioid-related and 16,863 stimulant-related poisoning hospitalizations from January 2016 to June 2023 in Canada (excluding Quebec)

  • A total of 3,036 opioid-related poisoning hospitalizations occurred so far in 2023 (January-June). This is an average of 17 hospitalizations per day.
  • A total of 1,107 stimulant-related poisoning hospitalizations occurred so far in 2023 (January-June). This is an average of six hospitalizations per day.
  • The median total length of hospital stay was three days for both opioid- and stimulant-related poisoning hospitalizations so far in 2023 (January-June).
  • The number of opioid-related poisoning hospitalizations in Canada reported so far in 2023 (January-June) was 11% higher compared to the same period in 2022. This is based on provisional data subject to change and should be interpreted with caution.

Data on opioid- and stimulant-related poisoning hospitalizations are not mutually exclusive. A high proportion of poisoning hospitalizations involving a stimulant also involved an opioid. Adding up those values would result in an overestimation of the burden of opioids and stimulants.

Where: A majority of accidental poisoning hospitalizations occurred in Ontario, British Columbia, and Alberta

  • So far in 2023 (January-June), most of the accidental opioid-related poisoning hospitalizations (90%) and accidental stimulant-related poisoning hospitalizations (91%) in Canada occurred in Ontario, British Columbia, and Alberta.
  • So far in 2023 (January-June), rates of accidental opioid-related hospitalizations in Canada were highest in British Columbia, Alberta, and Saskatchewan, while rates of accidental stimulant-related hospitalizations in Canada were highest in British Columbia, Saskatchewan, and Alberta.

Who: Most accidental poisoning hospitalizations were among males, with varying age distributions

  • So far in 2023 (January-June), males accounted for a higher proportion of accidental opioid-related poisoning hospitalizations (63%) and accidental stimulant-related poisoning hospitalizations (69%) than females.
  • So far in 2023 (January-June), the highest proportion of accidental opioid-related poisoning hospitalizations were among individuals aged 30 to 39 years (24%), followed by those aged 60 years or more (23%). The highest proportion of accidental stimulant-related poisoning hospitalizations were among individuals aged 30 to 39 years (28%), followed by those aged 40 to 49 years (23%).

Why: Toxicity of supply is contributing to the crisis

  • For opioid-related poisoning hospitalizations, fentanyl and its analogues were involved in 35% of accidental opioid-related poisoning hospitalizations, compared to 19% of intentional opioid-related poisoning hospitalizations so far in 2023 (January-June). The percentage of all opioid-related poisoning hospitalizations that involved fentanyl and its analogues has increased 100% since 2018 when national surveillance began, but appears to have stabilized in recent years.
  • For stimulant-related poisoning hospitalizations, fentanyl and its analogues were involved in 38% of accidental stimulant-related poisoning hospitalizations, compared to 8% of intentional stimulant-related poisoning hospitalizations so far in 2023 (January-June). The percentage of all stimulant-related poisoning hospitalizations that involved fentanyl and its analogues has increased 154% since 2018 when national surveillance began, but appears to have stabilized in recent years.

Multi-drug toxicity is a contributing factor to the crisis

  • Among accidental opioid-related poisoning hospitalizations so far in 2023 (January-June), 18% involved co-poisoning with a stimulant.
  • Among accidental stimulant-related poisoning hospitalizations so far in 2023 (January-June), 59% involved co-poisoning with an opioid.

Emergency Medical Services Download EMS report in .pdf format

What: There were more than 20,000 Emergency Medical Services (EMS) responses to suspected opioid-related overdoses so far in 2023 (January – June)

  • A total of 20,758 EMS responses to suspected opioid-related overdoses occurred so far in 2023 (January – June), based on available data from nine provinces and territories.

Who: Young- to middle-aged males continue to be the most affected

  • Of the EMS responses for suspected opioid-related overdoses so far in 2023 (January – June), 71% were among males.
  • The majority of EMS responses for suspected opioid-related overdoses so far in 2023 (January – June) were among those aged 20 to 49 years; however, variations are apparent between provinces and territories.
