Masks/Face Coverings

The Ontario Government currently mandates the use of masks/face coverings in the indoor premises of all businesses and organizations (including a business vehicle), as well as in certain outdoor situations, with some exceptions. TBDHU’s Instruction Letter to Employers, Business Owners and Operators for mandatory masks/face coverings also remains in effect. Where there are differences between the regulation and TBDHU’s instruction letter, whichever is the stricter expectation will be required.

For details, visit the Mandatory Masks Directive for Businesses and Organizations page.


Across Ontario, it is mandatory that the general public and employees wear a mask or other form of face covering in indoor spaces of all businesses and organization, including business vehicles, as well as in certain outdoor situations (unless exemptions apply). Masks are also recommended in any setting where it is difficult or not possible to keep 2 metres from others, including outdoors. It is important to know that mask wearing alone will not prevent the spread of COVID-19. 

Wearing a mask is part of a comprehensive COVID-19 prevention strategy that includes physical distancing, keeping hands clean, cleaning commonly-touched surfaces often, staying home when sick and getting tested if symptoms develop.

A mask can help stop the spread of respiratory droplets from a person’s mouth or nose (e.g. from a cough, sneeze, breathing or speaking moistly). Some evidence suggests that COVID-19 can be spread by people who aren't showing symptoms (asymptomatic) or have mild symptoms. Wearing a mask can be an added layer of protection.

*NOTE: Being fully vaccinated DOES NOT exempt an individual from mask requirements. Everyone, regardless of their vaccination status, must continue to wear a mask where required, unless they are entitled to an allowable exemption.
