Health officials are now suggesting the province's second death linked to COVID-19 likely came through community spread.
Halton Region Public Health officials say a man in his 50s with an underlying condition, died after receiving treatment at Oakville Trafalgar Memorial Hospital and Milton District Hospital.
The man did not travel outside of Canada and does not have a known link to another confirmed coronavirus case.
Ontario's chief medical officer of health Dr. David Williams calls the death unfortunate and says investigators are tying to understand more about the transmission.
Ontario reported its first COVID-19-related death earlier in the week — a 77-year-old man in the Muskoka region.
The province reported 43 new COVID-19 cases today -- bringing the total to 257.
