“They are also devastating and disappointing to the many SRCHC staff who work professionally and compassionately every day to deliver a range of essential health and well-being services to patients and clients in the area.”
The SRCHC says it continues to co-operate with Toronto police’s investigation.
A 32-year-old man, Damian Hudson, was also arrested last month and charged with second-degree murder in the case.
None of the charges announced in the investigation so far have been proven in court.
Toronto police say they are still looking for a third suspect involved in the shooting and anyone with information should contact them.
