The identity of the body of a man found in Lake Ontario on Aug. 5 by someone fishing near Niagara-on-the-Lake might not be known for weeks, police say.

The body was sent to the Centre of Forensic Sciences in Toronto for an autopsy and identification, Niagara Regional Police said in a news release.

“The cause of death remains under investigation,” Const. Jesse Vujasic told The Lake Report in an email.

“Positive identification of the deceased may take weeks as it is going to be done by DNA testing,” she said.

A man and a woman from Toronto drowned in the Niagara Gorge on Aug. 2. The body of the man has yet to be recovered. Police have made no connection between those drownings and the body found in Lake Ontario.

“The male who is missing in the Niagara River remains missing,” Vujasic said.
