In a press release on Wednesday, Durham Region said those who attended the September 19 event at the Caribbean Cultural Center, located near Colonel Sam Drive and Farewell Street, may have been exposed to the disease.
About 50 guests were at the wedding, officials said, along with eight to ten staff and an unspecified number of volunteers.
“The Department of Health has been made aware of eight cases of COVID-19 associated with this event and is struggling to obtain a full list of participants and their contact details,” the statement said.
“Following the eight positive cases of COVID-19, an epidemic was declared during this wedding which took place at the Caribbean Cultural Center.”
Officials say they are also in contact with two local workplaces that have been affected by the outbreak.
Although collection limits in Ontario have been reduced to 10 people indoors and 25 people outdoors, there is currently an exception for staffed businesses.
Large centers and venues can still organize weddings with a maximum of 50 people indoors and 100 outdoors.
Durham Region urges all who attended the wedding in Oshawa to call the Department of Health at 905-668-4113, ext. 2680.
