The Ontario Ministry of Labour requires the medical monitoring of employees who are potentially exposed to harmful substances in the workplace. The Occupational Health and Safety Act (RSO 1990) was designed, in part, to protect employees from work related illness and injury. Employees and employers must comply with health and safety regulations pertaining to these "designated substances" which have the potential to pose a health risk to the worker. MCI Medical Clinics conducts all Designated Substance Surveillance programs in accordance with the Occupational Health and Safety Act and the Ontario Ministry of Labour Regulations.

The surveillance program includes a pre-placement medical and periodic medicals, and specific medical testing that is specific to the designated substance used by your company.
