Code Silver is the latest color code that is part of hospital emergency preparedness in Canada.
It was introduced by the Ontario Hospital Association in 2016, 25 years after a standardized system of color codes, including Code Orange for an external disaster and Code Red for a fire, was introduced, according to an article on the Ontario Citizen website.
The code is a sign of the times, with a steady increase in gun violence across the country.
The Ottawa Hospital, which held a Code Orange training exercise last week based on the scenario of a mass shooting in the community, is, like other hospitals, preparing for a possible shooting within one of its campuses.
