But the death is unrelated to the Landmark Village retirement home where six people died, health officials said.
Two other patients recovered from the disease, bringing the total to 50.
Six of the deaths and 34 of the confirmed cases – eight employees and 26 residents – are due to an epidemic in Landmark. These numbers have increased since the weekend, as all residents and staff are currently being tested.
A second institutional outbreak was recently reported at the Lambton Meadowview Villa long-term care home near Petrolia, where an employee was reportedly tested positive on Wednesday.
Normally, an employee with a positive disease test would not trigger an epidemic in a long-term care home, but the guidelines changed with COVID-19, health officials said.
There were 984 local tests for COVID-19 – up from 865 on Sunday – with 15% of these positive, said public health officials. Saturday the percentage was 16% and Friday 17%.
The priority COVID-19 test was expanded on Thursday in Ontario and now includes essential workers, residents and staff of homeless shelters and group homes, as well as people living with health care workers.
Bluewater Health Sunday reported 16 patients hospitalized with COVID-19, and another 21 suspected of having the disease and awaiting test results.
A local taxi driver tested positive for COVID-19 and Lambton Public Health wants people who recently used the service to call the health service.
Anyone who has used Greg’s taxi service on April 1, 3, 6, 7, 8 or 10 is encouraged to call 519-383-8331, public health said in a statement.
