Park staff found the foot, inside a women’s running shoe, on the north shore of Gull Island in Lake Ontario.
The shoe is a size 11 Mizuno brand for a left foot and is grey, black and pink.
Provincial police were called in to investigate on Wednesday. After working with the Ontario Coroner’s office, they confirmed Friday that the remains were human.
Anyone with information that could help with the investigation is asked to contact provincial police at the Brighton detachment.
