SUDBURY -- Health officials in Sudbury, Ont. say the province's 37th confirmed case of COVID-19 is a man in his 50s, who didn't travel internationally before becoming ill.

During a Wednesday morning news conference, Dr. Penny Sutcliffe, medical officer of health with Public Health Sudbury and Districts, said the man went to the emergency department of Health Sciences North on March 7. He was discharged after testing and remains in self-isolation.

The patient attended the Prospectors & Developers Association of Canada convention in Toronto on March 2 and 3 as a delegate.

Dr. Sutcliffe says public health is still at the preliminary stages of the investigation, but it appears the man contracted the virus at the convention. Sudbury is working with Toronto Health to determine any other potential exposures.

Travelled down on March 1 in his personal vehicle

Travelled back March 4 in his personal vehicle

Went to work March 5 and 6

Dr. Sutcliffe says the individual did not travel abroad.
