One employee and nine clients at the Irene and Leslie Dubé Centre for Mental Health quickly got sick on New Year’s Day.
The centre has since been closed to admissions and visitors.
The earliest the facility could reopen is Wednesday.
The outbreak comes after St. Paul’s Hospital faced an outbreak in December.
It affected 35 people and forced the 20th Street hospital to shut down two units and visitations.
Meanwhile, in Prince Albert, a long-term care home has closed its doors to visitors due to an outbreak of a respiratory illness.
The Prince Albert Parkland Health Region says five residents at Parkland Terrace are showing symptoms.
Laboratory testing is being done to determine the organism involved in the outbreak.
Visitors are asked to reschedule their visits, if possible, until the outbreak is declared over.
However, for urgent or compassionate reasons, visitors can report to the nursing station where they will receive instruction on how to limit exposure and the risk of transmission.
