The Addiction Crisis in Blainville

Blainville is a municipality of approximately 60,000 people located in the Thérèse-De Blainville Regional County Municipality, about 35 km north of Montreal on the Laurentians North Shore. No city-specific overdose data for Blainville was found in available public health datasets. The municipality falls under the jurisdiction of the CISSS des Laurentides, which operates a service point in Thérèse-De Blainville and provides addiction and substance use services to residents. The broader provincial crisis is acutely felt in suburban and peri-urban communities across Quebec, including those in the greater Montreal periphery such as Blainville.

Canada recorded approximately 7,150 apparent opioid-related deaths in 2024 and 5,630 in 2025 — a 23% national decline attributed to changes in the illegal drug supply and expanded naloxone access. However, this improvement was not uniform: Quebec, Newfoundland and Labrador, and the Northwest Territories all saw increases from 2023 to 2024 while most other provinces declined. Since 2016, more than 56,000 Canadians have died from apparent opioid toxicity. Fentanyl and its analogues remain the dominant driver of fatal overdoses nationwide. The national baseline of approximately 7,560 apparent opioid toxicity deaths was recorded in 2023 (PHAC).

02. A crisis that did not start this month

Quebec is bucking a national trend of declining opioid deaths and is instead experiencing a worsening crisis. The INSPQ recorded 645 confirmed or suspected drug overdose deaths in 2024 — the highest annual total ever recorded in the province, up from 536 in 2023 and more than double the 2022 figure. As of late 2025, Quebec was on pace for approximately 604 deaths, meaning back-to-back years above 600. This stands in sharp contrast to most of Canada: nationally, opioid deaths dropped 23% in 2025 to 5,630. Fentanyl or its analogues were detected in approximately 65% of Quebec opioid deaths by late 2024, up from 33% in 2017. Emergency department visits for suspected opioid intoxication rose 38% in the first nine months of 2024 compared to the same period in 2023. Researchers at Université de Montréal concluded in a 2024 peer-reviewed study that Quebec has entered a new era of drug-related deaths driven by synthetic opioid contamination of the drug supply.

03. Why is it getting worse?

Quebec's worsening overdose crisis is driven by several converging factors: (1) Rapid fentanyl contamination of the drug supply — the proportion of overdose deaths involving fentanyl or analogues rose from 33% in 2017 to 65% by 2024, a trend that arrived later in Quebec than in western Canada but is now accelerating; (2) Toxic drug supply unpredictability — street drugs are increasingly adulterated with ultra-potent synthetic opioids, making any use potentially fatal regardless of tolerance; (3) Declining English-language addiction services — the MUHC Addiction Psychiatry Program in Montreal closed in 2024, while demand for remaining English residential treatment increased 16% in both 2024 and 2025; (4) Socioeconomic and geographic isolation — suburban communities like Blainville face barriers to harm reduction access that are more acute than in urban centres; (5) Stigma and under-treatment — Quebec's historically lower rates of opioid agonist therapy (methadone/buprenorphine) prescribing compared to other provinces leave more people without evidence-based treatment; (6) Post-pandemic social disruption — increased social isolation, mental health deterioration, and economic precarity have driven substance use initiation and relapse across age groups.

04. Where hope still lives

Communities across Quebec are responding with naloxone distribution, harm reduction programs, and peer support networks. Every person trained in naloxone use is a potential life saved.
