Ontario Launches Canada’s First Occupational Exposure Registry to Protect Workers

February 20, 2026

New digital portal will help track workers’ exposure, prevent occupational disease and build a healthier, more resilient workforce

As part of its plan to protect Ontario workers and their long-term health, the Ontario government is launching Canada’s first Occupational Exposure Registry (OER). This new secure digital portal includes an easy-to-use self-tracker that allows workers to record and track exposure to hazardous substances in the workplace. The portal builds on the government’s work to strengthen workplace health and safety by taking action to increase awareness and reduce harmful exposures, while giving workers a secure record they can reference throughout their careers.

“Ontario’s future depends on our workforce, and this tool represents an important step in protecting workers’ health on the job,” said David Piccini, Minister of Labour, Immigration, Training and Skills Development. “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.”

Starting today, workers can securely and anonymously submit exposure information through the online self-tracker in just a few minutes for one of 11 designated hazardous substances, such as asbestos, lead, mercury and silica. Workers can record details such as how their exposure occurred and what protective measures were in place, such as ventilation, training or personal protective equipment. Each submission generates a confirmation email and a record that can be downloaded. Having better information about harmful workplace exposures will help increase awareness and empower workers to better understand hazards and take steps to protect themselves.
