Construction and trades workers faced the highest opioid death rates in Ontario
A new report from the Ontario Drug Policy Research Network says workers in construction and trades accounted for about one-third of opioid toxicity deaths in Ontario cases where occupation was known between 2018 and 2024. The analysis points to a sharp occupational imbalance inside a wider public-health crisis, showing that opioid-related harm was not spread evenly across the workforce.
The report examined opioid toxicity deaths in Ontario from Jan. 1, 2018, through Dec. 31, 2024, using population-based health-care data from ICES, the nonprofit research institute that uses health data to study major health issues. Researchers linked that data with coroner information to assess how opioid toxicity deaths varied across employment sectors, including differences in death rates, how those rates changed over time, and the circumstances surrounding the deaths.
Across the full period, Ontario recorded nearly 16,000 deaths from opioid toxicity. About 3,500 of those cases included occupation information in the coroner’s report and were used in the occupational analysis. Within that subset, construction and trades stood out not only for having the highest death rates, but also for showing increases over the course of the study period.
A workforce pattern inside a broader overdose crisis
The report’s central finding is not that opioid toxicity is confined to a single type of job. Instead, it argues the opposite: people across many kinds of work are affected, but not in the same way and not with the same intensity. That matters because prevention strategies built for the general population may miss the specific risks and pressures present in different workplaces.
Lead author Shaleesa Ledlie, a senior research associate at the Ontario Drug Policy Research Network based at St. Michael’s Hospital and Unity Health Toronto, said the goal is to understand which groups are most affected so responses can be tailored to the realities of different workers and settings. In practice, that means sector-specific interventions may be necessary rather than a one-size-fits-all response.
The study found the construction and trades sector was particularly hard hit. It posted the highest death rates among the occupational groups analyzed, and those rates increased substantially during the COVID-19 pandemic before remaining elevated. That pattern suggests the pandemic was not a temporary spike that fully reversed after the most acute disruptions passed. Instead, elevated mortality persisted.
Why occupational detail matters
Occupation is not just a demographic label. It can signal differences in injury exposure, physical strain, job insecurity, worksite culture, access to benefits, shift patterns, and the ease or difficulty of reaching support services. The report does not present a single explanation for the disparity, but its findings support the idea that the conditions surrounding opioid toxicity deaths are nuanced and may differ significantly from one sector to another.
That is important for policy and workplace health planning. If one group is overrepresented in opioid toxicity deaths, employers, unions, public-health agencies, and provincial policymakers may need to consider more targeted harm-reduction and support measures. Those could include workplace education, improved access to treatment and health services, or approaches designed for workers whose schedules and job sites make standard care pathways harder to use. The report itself emphasizes the need for responses shaped around the needs of specific people and workplaces.
The Ontario data also highlights a basic challenge in overdose surveillance: occupation was known in only a portion of the total deaths. Out of nearly 16,000 opioid toxicity deaths during the study window, around 3,500 had occupation recorded in the coroner’s report and could be included in this analysis. That means the occupational picture is informative but incomplete, and better data collection could improve future prevention efforts.
Construction, trades and mining remain areas of concern
In addition to construction and trades, the report notes especially high opioid-related death rates in industries such as construction, trades, and mining. The inclusion of these sectors points to a broader cluster of higher-risk occupations rather than an isolated problem affecting only one job category. What ties them together in the report is not identical work, but elevated mortality and a trend that worsened considerably during the pandemic.
For employers and policymakers, that finding shifts the conversation from general awareness to sector-level accountability. A province-wide overdose emergency can still contain concentrated points of vulnerability, and those concentrations may require focused interventions where workers actually spend their time. In industries with dispersed job sites, contract work, and physically demanding conditions, conventional health messaging may not be enough.
The report arrives as opioid toxicity continues to shape health policy debates in Canada. By isolating workplace patterns, it adds a layer of specificity that can influence how resources are directed. Rather than treating all workers as equally exposed, the data suggests some industries should be considered priority settings for prevention and support.
What the findings change
The most significant contribution of the report is practical: it reframes opioid toxicity deaths as a workplace-linked public-health issue as well as a general population crisis. That does not mean work alone explains the deaths. It means occupational setting may influence risk, access to support, and how prevention measures should be delivered.
For Ontario, the immediate implication is that construction and trades workers should be central to any targeted response shaped by occupational evidence. More broadly, the findings strengthen the case for designing interventions that recognize the realities of specific sectors instead of assuming every worker encounters the crisis in the same way.
With death rates in construction and trades rising over the study period and staying high after the pandemic surge, the report’s warning is straightforward. The overdose crisis is touching every part of society, but some groups are carrying more of the burden. Understanding that distribution is likely to be a prerequisite for reducing it.
