TORONTO -- A long-time cleaner at Brampton’s Civic Hospital has died of COVID-19, marking the first known death of a health-care worker in the province due to the virus.

Peel Region Public Health said that early on Thursday, a man in his 50s who worked as an environmental services associate at the hospital for many years died of the virus.

“He had been in intensive care at Brampton Civic. An investigation revealed he likely acquired the virus in the community and not at work,” officials said.

Peel Region had 786 confirmed COVID-19 cases as of Thursday, and 10 deaths.

“Every loss of life to COVID-19 is tragic. On behalf of the Region of Peel, I extend our deepest condolences to his family both at home and at work,” Dr. Lawrence Loh, Peel’s Interim Medical Officer of Health said. “He played an important role in keeping the health care system working, and we mourn his loss.”

Loh told CP24 health officials believed the man acquired the virus in the community.

“We conducted thorough exposure assessment. As far as we could tell, there was no specific link to the hospital or any healthcare setting,” Loh said.

He said the hospital is implementing enhanced measures to protect its staff from the virus. It includes enhanced screening measures, increased personal protective measures for staff and limiting the number of visitors.

It is also important that the community continue to stay at home and follow physical distancing rules to keep frontline workers from getting COVID-19, Loh said.

Brampton Mayor Patrick Brown said the man’s death is “heartbreaking.”

“This is a healthy 58-year-old individual who is a dedicated employee of Brampton Civic. It hits home. It shows you how dangerous COVID-19 is.

“This pandemic is affecting people in our own backyard.”

As of Thursday, the case fatality rate for people aged 40 to 59 has been 0.7 per cent, with 13 people in the age group succumbing to the disease.

Several healthcare workers in the Medicine Unit 4B at Trillium Health Partners-Mississauga Hospital have contracted the virus, hospital officials said Thursday.
