Toronto Public Health is collaborating with the Toronto Overdose Early Warning and Alert Partnership to provide timely information on overdose activity, with a current focus on opioids. Additional data and indicators may be added to this site as they become available.

Last Updated: December 5, 2018

Toronto Paramedic Services is collaborating with Toronto Public Health to share information on calls for suspected opioid overdoses received by paramedics in Toronto. This includes the number and location of cases where the responding paramedic suspects an opioid overdose. This may differ from the patient’s final diagnosis in hospital or cause of death determined by the coroner. These findings are preliminary and subject to change. Please see the Data Notes tab for more information on these indicators.

New Report: Detailed analysis from the first complete year of data on suspected opioid overdose calls to Toronto Paramedic Services (TPaS) is complete. Trends in Paramedic-Attended Opioid Overdoses: A Review of Suspected Opioid Overdoses in Toronto Paramedic Services Data, 2017/18 contains information on demographics of cases, trends by month, day, and time, and Toronto neighbourhood comparisons.

Since August 7, 2017, Toronto Paramedic Service attended 61 non-fatal and 3 fatal suspected opioid overdoses per week on average. Fatal cases include those where the patient died on scene and the coroner was notified.

Over this period, an average of 13 non-fatal cases per week had naloxone administered by a community member before paramedic arrival. Paramedics administered naloxone in an average of 8 non-fatal cases per week.

Substance-related emergency department visits at Toronto hospitals fluctuated between July 2018 and November 2018. The number of suspected overdose cases also fluctuated slightly, but otherwise remained fairly stable. Note that neither of these indicators are specific to opioids. Substance-related emergency department visits may be due to intoxication, addiction, overdose, or withdrawal. Suspected overdose cases are a subset of substance-related visits that specifically mention overdose in the chief complaint and meet a set of inclusion criteria. Please see the Data Notes tab for more information on these indicators.

The number emergency department visits has fluctuated over the past two years with a general upward trend. The largest increase was seen between June and September 2017 followed by a decrease in the fall of 2017. Hospitalizations for opioid poisoning remained relatively stable over the period. Note that changes to hospital reporting for opioid overdoses at the start of May 2017 may account for some of the increase in this indicator. Please see the Data Notes tab for more information on this indicator.

On August 21, 2017, Toronto Public Health opened the interim site for supervised injection services at The Works. Services moved to the permanent site on October 30, 2017.

Supervised injection services are health services that provide a hygienic environment for people to inject pre-obtained drugs under the supervision of a trained health care professional. In addition to supervised injection, individuals are provided with sterile injection supplies, education on safer injection, overdose prevention and intervention, medical and counselling services, and referrals to drug treatment, housing, income support and other services. Please see the Data Notes tab for more information on these indicators.

As of December 2, 2018, there were 28,154 visits to the supervised injection service. There were 469 visits where an overdose occurred, including 169 visits where the client required naloxone.

15/01/2018: Survey on Opioid Awareness (2017) Results
Statistics Canada has released results from the Survey on Opioid Awareness. The survey found that 29% of Canadians aged 18 years and older reported using some form of opioids in the past five years. It also found that 78% of Ontarians were ‘very aware’ or ‘somewhat aware’ of the opioid issue. For more information see the full results and infographicPlease note that Toronto-specific statistics are not available

29/05/2017: Interactive tool on opioid-related harms data
Public Health Ontario recently released an interactive tool that explores trends in opioid-related emergency department visits, hospitalizations and deaths from 2003 to 2015 in Ontario. Toronto Public Health has created a summary document that reviews the key findings for Toronto.

Please note that the interactive tool and summary document capture outcomes occurring among Toronto residents only and as such, will include fewer occurrences than those included on this website (which capture all overdose outcomes occurring in Toronto, regardless of where an individual resides).

28/03/2017: Toronto Overdose Action Plan

Toronto Public Health worked with community partners to develop the Toronto Overdose Action Plan: Prevention & Response, which was endorsed by the Board of Health on March 20, 2017. The Plan includes a comprehensive set of actions for all orders of government to prevent and respond to drug overdoses.

28/03/2017: Naloxone information

The Province of Ontario has launched a new website with information on where to get free naloxone kits in your area.

Paramedic Response

Weekly number of suspected opioid overdose calls received by Toronto Paramedic Services, Toronto

Source: Toronto Paramedic Services. Paramedic Electronic Patient Care Record.

Data Notes:

  • This indicator is preliminary and subject to change pending further review of the data source.
  • This indicator includes cases where the responding paramedic suspects an opioid overdose. This may differ from the final diagnosis in hospital or cause of death determined by the coroner.
  • Fatal cases includes those where the patient died on scene and the coroner was notified. Patients who die after being transported to hospital may be miscategorized here as ‘non-fatal’ cases.
  • This indicator includes only instances where 911 is called and underestimates the true number of overdoses in the community.

Data Notes:

  • This indicator is preliminary and subject to change pending further review of the data source.
  • The map shows the locations where paramedics made contact with patients, which may or may not be the same location from which 911 was called.
  • The colours of the heat map indicate the relative density, defined as the number of cases per unit area. As a stretch legend is used to visualize the density, this map should not be interpreted in absolute terms when compared to heat maps from other time periods.
  • Suspected opioid overdoses occurring slightly outside the City of Toronto boundaries were excluded from the map.
  • This indicator includes cases where the responding paramedic suspects an opioid overdose. This may differ from the final diagnosis in hospital or cause of death determined by the coroner.
  • This indicator includes only instances where 911 is called and underestimates the true number of overdoses in the community.

Hospital Visits

Data Notes:

  • This data source only captures substance-related visits that result in an individual seeking care in a hospital setting. This is likely an underestimation of the true burden of overdose in the population.
  • ACES is a syndromic surveillance system that classifies visits and admissions into ‘syndromes’ using algorithms to assess and classify open text from the chief compliant recorded at triage or registration. This process allows ACES to provide daily counts of visits and admissions.
  • This data sources captures visits to acute care facilities in Toronto. However, it does not currently capture visits to Sunnybrook hospital. Moreover specialty hospitals, such as the Women’s College Hospital are not captured. Visits to the Centre for Addiction and Mental Health are included in ACES as of November 23, 2017.
  • ‘Substance-related visits’ include instances of intoxication, addiction, overdose, or withdrawal.
  • ‘Substance-related visits’ include those caused by opioids or non-opioid related drugs (OPI and TOX syndromes, combined). It excludes those related to alcohol.
  • This indicator includes all visits to Toronto hospitals, regardless of whether or not the individual resides in Toronto.
  • Monday to Sunday week units are used here as the unit of analysis, with the starting date of each week labeled on the x-axis of the graph.

Data Notes:

  • This indicator is only available from May 2017 onwards, due to availability of data.
  • This data source only captures suspected overdoses that result in an individual seeking care in a hospital setting. This is likely an underestimation of the true burden of overdose in the population.
  • ACES is a syndromic surveillance system that classifies visits and admissions into ‘syndromes’ using algorithms to assess and classify open text from the chief compliant recorded at triage or registration. This process allows ACES to provide daily counts of visits.
  • ‘Suspected overdoses’ refer to a subset of substance-related visits that specifically reference ‘overdose’ in the chief complaint. It excludes overdoses that specify a substance of non-interest (e.g. alcohol, over-the-counter medication, prescription drugs of non-interest such as blood pressure medication, and toxic products such as cleaning products).
  • ‘Suspected overdoses’ include only visits with a Canadian Triage Acuity Score of 1 (Resuscitation), 2 (Emergency), or missing.
  • ‘Suspected overdoses’ excludes visits to children less than 10 years of age.
  • For the majority of visits, the substance causing overdoses is not specified. It is important to note that this indicator measures overdoses from all types of substances, not just opioids.
  • ‘Suspected overdoses’ also excludes intentional overdoses or those related to self-harm.
  • This data sources captures visits to acute care facilities in Toronto. However, it does not currently capture visits to Sunnybrook hospital. Moreover specialty hospitals, such as Women’s College Hospital are not captured. Visits to the Centre for Addiction and Mental Health are included in ACES as of November 23, 2017.

Data Notes:

  • This indicator captures new admissions to treatment centres in Toronto only.
  • Individuals who access addiction treatment services through primary care, hospitals, private clinics and federally-funded First Nations health service providers are not included in this indicator.
  • Presenting problem substances are self-reported by clients. Individuals can list up to 5 substances upon admission.
  • Individuals who specify multiple presenting problem substances are counted as a new admission for each type of substance. For instance, if an individuals specifies heroin and prescription opioids as presenting problem substances, they will be counted as a new admission for both heroin and prescription opioids.
  • Completeness of this indicator is limited by timeliness of what is submitted by health service providers. This can vary from provider to provider. Counts for recent weeks may be subject to change, as more service providers complete their reporting.
