B.C. has no provincewide mandate for mask-wearing, but many businesses and organizations have policies of their own.
Here is a list of prominent locations and organizations that have made masks mandatory.
As the coronavirus pandemic develops and changes in British Columbia, so too have policies on face coverings. As a result, this list is likely to change over time and may not be exhaustive.
In most cases, these policies have exemptions for people with certain medical conditions and for young children. There may also be exemptions for some workers who are behind Plexiglas barriers or taking other precautions.
The B.C. Centre for Disease Control advises masks can help protect others from catching the coronavirus, which causes COVID-19, especially in situations where physical distancing is not possible.
"Any mask, no matter how good it is at catching droplets or how well it seals, will have minimal effect if it is not used together with other preventive measures, such as frequent hand washing and physical distancing," the centre adds.
BC Transit: Anyone on BC Transit buses must wear a face covering. There are exemptions for certain passengers and employees.
TransLink: Anyone on a TransLink vehicle must wear a non-medical mask or face covering, with some exemptions. TransLink says branded cards are available for people with underlying medical conditions who cannot wear masks.
