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

February 20, 2026

As part of its plan to protect Ontario workers and their long-term health, the Ontario government is launching Canada’s first-ever 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 such as asbestos, lead, mercury and silica in the workplace. The portal builds on the 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.
