Employers are expected to follow OHSR5.2 and OHSR5.59 in relation to COVID-19 exposure in their workplace.
People who public health has determined are infected with COVID-19 will be monitored by their local public health office, which will conduct contact tracing and provide them with advice as to treatment, self-isolation, and eventual return to work.
Being considered to be infected with COVID-19 is a medical diagnosis, which is personal information. The employer will need to follow directions provided by public health, if a public health officer advises them that a person who is or has been present at the workplace is an infected person and requests that the employer report the contact information, if known, of each person who may have been exposed to the infected person, and consider their privacy law obligations.
