The Addiction Crisis in Saint-Jean-sur-Richelieu

Saint-Jean-sur-Richelieu, a mid-sized city of roughly 100,000 in the Montérégie region south of Montreal, has been identified as one of the hardest-hit communities in Quebec for opioid-related hospitalizations. A 2018 Canadian Institute for Health Information (CIHI) report — the most granular city-level data publicly available — found the city had a rate of 26.2 opioid-related hospitalizations per 100,000 inhabitants, compared to 6.9 per 100,000 in Montreal: roughly four times higher. This placed Saint-Jean-sur-Richelieu among the worst-affected medium-sized Canadian cities, alongside Kelowna, BC. Researchers attribute this elevated rate to the social determinants common in smaller industrial cities: lower employment rates, higher poverty concentration, and reduced access to harm-reduction and treatment services compared to large urban centres. Local addiction services exist — the Centre de réadaptation en dépendance de la Montérégie-Ouest (CRD) operates at 202 rue Saint-Louis — but no city-specific overdose death data has been published at the municipal level. Law enforcement in the region has seen active drug-trafficking prosecutions in 2025–2026, including a network linked to organized crime.

Nationally, Canada recorded approximately 7,560 apparent opioid toxicity deaths in 2023 (PHAC) and approximately 7,150 in 2024 — a 17% year-over-year decline driven by improvements in British Columbia, Alberta, and Ontario. Quebec is a critical outlier: while the rest of Canada trends downward, Quebec's deaths hit a record high of 645 in 2024. The national rate of opioid hospitalization in small cities (population 50,000–99,999) is 2.5 times higher than in large urban centres, a pattern Saint-Jean-sur-Richelieu exemplifies at an even more extreme ratio versus Montreal. Fentanyl contamination of the unregulated drug supply is the primary driver of deaths across all provinces.

02. A crisis that did not start this month

Quebec is bucking the national trend on drug overdose deaths. While apparent opioid-related deaths dropped 17% across Canada in 2024 (to approximately 7,150 nationally), Quebec recorded 645 confirmed or suspected drug overdose deaths in 2024 — the highest annual total ever recorded in the province and roughly double the 2022 figure. The province is on pace for a second consecutive year near or above 600 deaths in 2025. Fentanyl or its analogues are now detected in nearly two-thirds of overdose deaths, up from 33% in 2017. Quebec's per-capita death rate rose from 5.1 per 100,000 in 2018 to 7.3 per 100,000 in 2024. The INSPQ tracks this data continuously; carfentanil has also been detected in Montreal's fentanyl supply. Quebec introduced a universal free naloxone program in November 2017 (available at pharmacies to anyone aged 14+), but experts warn the province needs to do substantially more — particularly as English-language addiction services contract (the MUHC Addiction Psychiatry Program in Montreal closed in 2024).

03. Why is it getting worse?

Several factors converge to make Saint-Jean-sur-Richelieu and similar mid-sized Quebec cities disproportionately affected. (1) Social determinants: lower employment rates and higher poverty concentration relative to Montreal create elevated vulnerability to substance use disorder. (2) Supply-side contamination: fentanyl and its analogues — including carfentanil — now appear in nearly two-thirds of Quebec overdose deaths, making any opioid use far more lethal than a decade ago. (3) Treatment access gaps: harm-reduction and addiction-medicine services are denser in large cities; mid-sized cities like Saint-Jean-sur-Richelieu have fewer supervised consumption sites and fewer opioid agonist therapy prescribers per capita. (4) Organized crime supply networks: law enforcement operations in 2025–2026 confirmed active drug trafficking networks linked to organized crime operating in the Saint-Jean-sur-Richelieu area. (5) Quebec-specific lag: Quebec entered the fentanyl era later than western provinces, so the overdose death curve is still climbing while B.C., Alberta, and Ontario have begun to plateau or decline nationally.

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.
