Protecting Worker Health and Supporting Employer Compliance

Medical surveillance is the ongoing process of conducting health testing and analyzing employee health information to monitor the effects of workplace exposures. These programs play a vital role in maintaining worker health, preventing occupational disease, and ensuring compliance with Ontario’s occupational health and safety legislation.

Regulatory Requirements in Ontario

Under Ontario’s Occupational Health & Safety Act (OHSA) and its Designated Substance Regulations, certain employers are legally required to implement medical surveillance programs. These requirements apply to workplaces where employees may be exposed to designated substances or other regulated hazards. Medical surveillance ensures that exposure levels remain within safe limits and that workers receive appropriate health monitoring and follow-up.

Mobile Medical Testing

Occu-Med Health Services Inc. provides mobile medical surveillance programs across Ontario. Using mobile testing units and experienced occupational health nurses, Occu-Med delivers all required health testing directly at the worksite. This approach minimizes downtime, reduces travel time for employees, and allows employers to maintain productivity while meeting their regulatory responsibilities.

Monitoring Workplace Exposures

Regular monitoring of exposure to workplace hazards—such as chemicals, noise, and ergonomic risks—is an essential part of any occupational health program. Occu-Med’s surveillance services may include:

• Environmental Monitoring: Measuring the concentration of hazardous substances in the air or workplace environment.
• Biological Monitoring: Testing biological samples (e.g., blood or urine) to assess internal exposure levels and identify potential health effects.

This combined approach provides a comprehensive understanding of both environmental and individual exposure, allowing for early identification of potential health risks.

Clear and Compliant Reporting

Employers receive detailed reports that include summaries of test findings and required “Fit Letters” as outlined by the OHSA and related regulations. All reports and health information are managed in full compliance with the Ontario Personal Health Information Protection Act (PHIPA), ensuring confidentiality and proper handling of employee data.
