Ontario has launched what it describes as Canada’s first Occupational Exposure Registry (OER), a digital portal designed to let workers document exposure to hazardous substances over the course of their careers and support efforts to prevent occupational disease.
Announced by the Ministry of Labour, Immigration, Training and Skills Development, the secure online system includes a self-tracking tool that allows workers to record and track exposure to one of 11 designated hazardous substances, such as asbestos, lead, mercury and silica. Workers can enter details about how their exposure occurred and note what protective measures were in place, including ventilation, training or personal protective equipment. Each submission generates a confirmation email and a downloadable record for workers to keep.
Government says new portal will support prevention and earlier detection
“Ontario’s future depends on our workforce, and this tool represents an important step in protecting workers’ health on the job,” said Labour Minister David Piccini.
“This first-in Canada Occupational Exposure Registry will give workers the ability to securely track and better understand their exposure risks, helping inform prevention efforts and stop occupational disease before it starts.”
The province says occupational illnesses are frequently underreported and can be difficult to diagnose because of long latency periods between exposure and the onset of symptoms. By giving workers a way to build a personal exposure history that can follow them across jobs and worksites, officials say the registry can support medical assessments if symptoms arise years later.
According to the ministry, workers can begin using the online self-tracker immediately and can submit information securely and anonymously in just a few minutes. Participation in the registry is voluntary and worker-driven; individuals decide whether to register and are responsible for updating their own exposure information over time.
A ministry description of the tool says information entered into the Self‑Tracker will be used by Ontario’s Chief Prevention Officer to support prevention efforts aimed at reducing occupational diseases and improving worker health and safety, including program development and training. The information will remain within the Government of Ontario and, according to the description, will not be used for enforcement purposes. Aggregated and de‑identified data may be used to improve the functionality and user experience of the Self‑Tracker and may also be shared with health and safety partners to help inform prevention strategies.
The registry was first promised in the Working for Workers Act, 2023, and is being presented as part of a broader strategy to strengthen workplace health and safety. It also responds to recommendations from Ontario’s 2023 Occupational Disease Landscape Review, including calls for improved data collection and better tracking of exposure trends over time, as well as more accessible digital tools for workers, health-care providers and disease prevention partners.
“Our government is taking bold and innovative action to make it easier for Ontarians to stay safe and healthy in the workplace and beyond,” said Deputy Premier and Health Minister Sylvia Jones. “The launch of Canada’s first Occupational Exposure Registry is one more way we are protecting Ontario workers and communities for years to come.”
