Mandatory Blood Testing

The Mandatory Blood Testing Act (2006) of Ontario allows blood samples to be taken from an individual or “source person” when emergency service workers, or victims of crime, have been exposed to that person’s bodily fluids such as saliva or blood. The sample is tested for HIV, hepatitis B and hepatitis C.

The law was put into place to make sure that those who are exposed can find out faster if they may be at risk of being infected with a disease. The law outlines specific procedures that must be followed to protect the rights of both the “source person” and the person who may have been exposed.

The Medical Officer of Health (MOH) for the Thunder Bay District Health Unit will receive and screen the application to make sure it meets the requirements of the Mandatory Blood Testing Act. The MOH will contact the source person to see if they are willing to voluntarily provide a sample. If the source person refuses, then the MOH may decide to forward the application to the Consent and Capacity Board for a final decision.


Designated Officers

Each service organization (police, fire, EMS, etc.) has a Designated Officer (DO). The DO receives reports from the Health Unit regarding possible exposures and reviews reports from workers from service organizations. The DO is also trained to provide counselling, guidance and support to exposed workers.
