Dr. Bonnie Henry, B.C.'s top medical health officer, declared a public health emergency in the province Tuesday afternoon.
Henry also announced there are three new deaths and 83 new cases of coronavirus (COVID-19).
Two of the new deaths are residents in the Lynn Valley Care Centre in North Vancouver.
The third was a person in their 80s, who died in hospital.
Henry then revealed that all bars in the province must close, as they can't guarantee the kind of safe social distancing (two metres) needed to prevent spread of the disease.
She said declaring a public health emergency allows the government to act faster and to deploy the police to enforce the order if necessary.
As well as bars and clubs, police officers could be used to take action if people are not following a self-isolation order.
"This is a time for calm," Henry added.
She said some restaurants and cafes may be able to operate, if they can maintain social distances between customers and staff.
Henry further pleaded with employers to allow staff to work from home, if at all possible.
"We need to break the chain of transmission. The risk is changing rapidly," she directed at employers.
Five provinces across Canada have now declared a health emergency.
Henry said 116 of the reported cases of COVID-19 are in the Vancouver Coastal Health region, 47 in Fraser Health, 12 on Vancouver Island, seven in the Interior and four in Northern Health.
She further urged people to exercise proper hand, coughing habits, avoid touching your face and staying away from others.
Seven of the current cases, Henry said, are in hospital, four of whom are in intensive care.
