Police in Cambridge say the unidentified remains of what could be a young woman will be examined by pathologists at the Centre for Forensic Sciences in Toronto.
The remains were discovered along the Galt waterfront in the Water Street South and Cedar Street area by someone fishing in the Grand River on Friday.
Mike Chappell was fishing at a spot nearby on Friday evening when the police investigation began. He noted the arrival of several police cruisers as well as officers taking notes and a police forensic identification vehicle.
"They started taking pictures of something in the water, which I assumed was a body and then [I] kind of got a chill when that happened," he said.
The Ontario Coroner's Office and a specialized dive team from the Niagara Regional Police was called in to aid in the investigation.
Police are asking anyone with information to call 519-650-8500 extension 8666.
