A troubling trend in the data
A new CBC analysis has found that calls to paramedics for non-fatal opioid overdoses are climbing in several Ontario cities, painting a worrying picture of the province's ongoing drug crisis. The most dramatic jump was recorded in Hamilton, where non-fatal overdose calls nearly tripled in just the first five months of 2026 compared to the same period a year earlier.
While Hamilton's numbers stand out, the CBC review found the upward trend wasn't isolated to one city — several other Ontario municipalities logged similar increases in paramedic callouts for overdoses that didn't result in death. Taken together, the data suggests a broader shift is underway in how the toxic drug supply is affecting communities across the province, not just in one region.
What's driving the increase
Researchers and frontline social workers cited in the analysis point to two major factors behind the rise. First is the ongoing volatility of the illicit drug supply, which has grown increasingly unpredictable and dangerous in recent years as unregulated substances are cut with stronger and more unstable compounds. Second, and perhaps more significant from a policy standpoint, is the closure of supervised consumption sites across Ontario over the past two years.
Those sites, which allowed people to use drugs under medical supervision with staff on hand to respond to overdoses immediately, had long been credited by harm-reduction advocates with preventing deaths and connecting people to health and social services. Their closure has left a gap that some experts argue is now showing up in the paramedic call data — as fewer overdoses are being caught and managed on-site, more are becoming emergency calls requiring a full ambulance response.
Why this matters beyond the numbers
Each non-fatal overdose call represents not just a statistic but a person in crisis, and a system increasingly stretched to respond. Paramedic services already under pressure from rising call volumes across the board are now absorbing more of this specific type of emergency, a burden that ripples outward to hospital emergency rooms and community health resources as well.
The data also raises fresh questions for provincial policymakers about the trade-offs involved in closing supervised consumption sites, a move that was framed by the Ontario government as part of a broader shift toward treatment and recovery-focused approaches to addiction. Critics of that shift have long warned that removing supervised sites without equivalent replacement services could push overdose risk back into public spaces and put more pressure on emergency responders.
The bigger picture
Ontario's experience is part of a larger, ongoing national conversation about how best to respond to the opioid crisis — balancing harm reduction, enforcement, and treatment approaches. As paramedic data continues to show rising call volumes in cities like Hamilton, pressure may grow on provincial officials to reassess how the closures of consumption sites are affecting frontline health outcomes.
For now, the numbers serve as a stark reminder that the crisis remains far from resolved, and that its effects are being felt unevenly but persistently across Ontario's cities.
