Toronto’s Drug Checking Service has been awarded two years of support by Health Canada’s Substance Use and Addictions Program to extend and expand the delivery of drug checking services in Ontario. Phase 2 will be led by Karen McDonald – a leader in drug checking service provision and unregulated drug market monitoring, who was responsible for designing and overseeing the program throughout its pilot period – in collaboration with the program’s member organizations. The program will remain housed within MAP Centre for Urban Health Solutions at St. Michael’s Hospital, a site of Unity Health Toronto.

Drug checking is a public health service that aims to reduce the harms associated with substance use by uncovering the contents of the unregulated drug supply. While access has remained limited within Canada, drug checking services in Toronto, across British Columbia, and elsewhere, have had a positive and quantifiable impact on responding to Canada’s toxic drug supply crisis. For example, drug checking:

• Provides potentially life-saving information to those at highest risk of overdose
• Facilitates behaviour change that reduces the risk of overdose
• Provides a new gateway to accessing harm reduction services
• Provides the only source of real time monitoring and public dissemination of unregulated drug market trends
• Provides data that informs clinicians and care and improves health and social services
• Is valuable to people who use drugs, empowering them to advocate for themselves and help develop solutions that impact them.

The pilot program for Toronto’s Drug Checking Service launched in October 2019 within Dr. Dan Werb’s Centre on Drug Policy Evaluation. Over the course of the pilot period, more than 10,000 samples from the unregulated drug supply were checked and over 450 unique drugs were identified – many of which can be directly linked to overdose. Service users, who submitted substance or used equipment samples to be checked, were provided with detailed information on the composition of their drugs, along with tailored strategies to reduce harm and referrals to drug-related, health, and social services via integrated community health agencies (Moss Park Consumption and Treatment Service, Parkdale Queen West Community Health Centre and the TRIP! Project, South Riverdale Community Health Centre, The Works at Toronto Public Health). Samples were analyzed by the clinical laboratories at the Centre for Addiction and Mental Health and St. Michael’s Hospital. Beyond educating individual service users, results for all samples were collated and analyzed to perform unregulated drug market monitoring, then translated and
publicly disseminated every other week to communicate drug market trends to those who could not directly access the service, as well as to inform care for people who use drugs, advocacy, policy, and research.

Key objectives for phase 2 of the program are to:

• Improve access to drug checking in Toronto by increasing the number of sites that offer services
• Support the delivery of drug checking services in jurisdictions across Ontario by sharing tools, resources, and expertise to reduce the barriers associated with offering services while increasing health system efficiencies
• Conduct unregulated drug market monitoring for Ontario by bringing together data generated from checking samples using a variety of drug checking technologies
• Translate findings to advocate for services and safer alternatives for people who use drugs

Toronto’s Drug Checking Service has been without a long-term funding commitment since March 31, 2023. A special thank you to the St. Michael’s Hospital Foundation and Public Health Agency of Canada for their support during this period of uncertainty. Additionally, we thank the community of people who use drugs in Toronto who access our service and provide ongoing feedback to improve it, as well as our members, partners, and collaborators. We are grateful to continue to work with and serve you.
