The Saskatoon jail is the only centre where mass testing of staff and inmates has taken place. The province says it will only test people in other correctional centres who show COVID-19 symptoms. "Mass testing events were conducted at the Saskatoon Correctional Centre in late November as part of the overall outbreak management response after symptomatic staff and offenders in the general population tested positive for COVID-19," Ministry of Corrections and Policing spokesperson Noel Busse wrote in an email.
