Employers may need to update workplace policies

There may be different or specific advice related to higher risk workplaces or if an outbreak occurs. It is up to the employer to determine whether and how to update their own workplace policies.

Employers are also reminded to consider basic elements of infection control that should be present in all workplaces, such as encouraging proper hand hygiene, respiratory etiquette, reminding workers about the signs and symptoms of respiratory diseases commonly seen in the fall/winter months and advising workers not to come into the workplace if they feel unwell.

Having a safety plan and taking a layered approach to controls will protect against COVID-19 transmission in the workplace and help all businesses across Ontario to stay open and safe.
