Lambton’s overdose crisis is unfolding inside a wider affordability crisis

Lambton’s overdose crisis is unfolding alongside a wider affordability crisis. As opioid-poisoning EMS calls rise sharply, local housing, food insecurity and public-health reports show the same crisis is also tied to poverty, unstable housing, hunger and the conditions people are trying to survive.

Lambton’s rising overdose calls are not happening in isolation.

They are happening in a community where food insecurity has surged, rents have climbed, shelters are strained, and public reports repeatedly connect homelessness, mental health, substance use and poverty.

Lambton EMS responded to 149 opioid-poisoning calls in the first five months of 2026, compared with 62 during the same period last year. That increase is the emergency signal. But the conditions around that emergency are visible in other local numbers.

Sarnia’s Housing Needs Assessment says the city faces a persistent affordable housing crisis, including a need for supportive housing for people experiencing homelessness and people with mental-health issues. The report says a 2021 point-in-time count identified 236 people experiencing homelessness. Of those counted, 66 per cent were identified as having mental-health issues and 80 per cent reported substance use.

The same count also found Indigenous people were sharply overrepresented among those experiencing homelessness. Thirty-three per cent of people counted identified as Indigenous, compared with 4.4 per cent of the Sarnia census area.

That figure points to a deeper structural reality, not an individual one. Homelessness, poverty, colonial harm, mental health and substance use are often treated as separate issues, but local reports show they are overlapping in the lives of many people.

That does not mean homelessness causes addiction, or that addiction explains homelessness. It means Lambton’s overdose crisis is unfolding inside a wider system of instability, where housing, health, poverty and survival are already connected.

The housing assessment also says people receiving Ontario Works or ODSP cannot find housing they can afford on shelter allowances that are less than half of average market rents. It says the average rent for a one-bedroom apartment in Sarnia has increased 58 per cent over the last decade.

That matters in an overdose crisis because stability is difficult to build without stable housing.

A person who survives an overdose may still return to a shelter, encampment, unsafe room, motel, couch, or no housing at all. They may still lack transportation, a phone, regular food, primary care, clean clothing, income security or a safe place to recover. The emergency may have ended, but the conditions around the emergency remain.

Food insecurity adds another layer.

Lambton Public Health data presented to county council showed 25.4 per cent of Lambton households were food insecure in the most recent 2023–2024 data, up from 13.6 per cent in 2021–2022. The estimated cost to feed a family of four in Lambton was about $1,197 per month, or $275 per week.

That is more than a household-budget problem. Food insecurity is part of the same pressure system that makes health harder to maintain and recovery harder to sustain.

The Inn of the Good Shepherd is one of the agencies absorbing that pressure. Its food bank provides food packages with staples and fresh food, can be accessed every 21 days, and requires proof of income, rent or mortgage information, and identification for household members. The Inn says its food bank sees more than 2,400 people on average each month, including 940 children.

That work is often described as charity. In the context of the overdose crisis, it is also survival infrastructure.

Food banks, shelters, drop-ins and outreach services are where poverty becomes visible before other systems become involved. They are also where people often remain after the ambulance leaves, after a hospital visit ends, or after a short-term intervention fails to become long-term stability.

Lambton’s own Drug and Alcohol Strategy recognizes that substance use cannot be separated from the conditions around it. The strategy says a collaborative approach is needed to address root causes of problematic substance use, including socioeconomic status, housing availability, family supports, accessible mental-health care, regulated substance supply, and the legacies of colonization and discrimination.

That broader frame is important.

The overdose crisis is often measured at the point of emergency, when someone stops breathing or nearly stops breathing and 911 is called. EMS call numbers show when the crisis has reached its most urgent point.

But the pressures around that moment usually begin much earlier.

They can begin with unaffordable rent, an empty fridge, untreated pain, trauma, isolation, mental illness, poverty, or a life where stability is constantly out of reach. Substance use is complicated, and no single explanation fits everyone. But public-health and housing documents already show that the local crisis is tied to more than drugs alone.

That distinction matters for how Lambton understands the 2026 spike.

If the community treats overdose only as a medical emergency, it will see ambulances and naloxone. If it treats overdose only as a drug issue, it will see supply and enforcement. Both are part of the story.

But the local record points to a larger reality: overdose risk is unfolding alongside homelessness, food insecurity, unaffordable housing and poverty.

The rise in opioid-poisoning calls is therefore not only a warning about the drug supply.

It is also a warning about the conditions surrounding it.
