The Ontario Provincial Police are putting out another call for assistance as they continue the investigation into the disappearance of a Toronto woman in the Rainbow Falls Provincial Park, located between Schreiber and Rossport, 16 years ago.

Christina Calayca was last seen on the morning of August 6th 2007 while camping at the park just off of Highway 17 when she went for a run and was never seen again.

Searches were carried out but no trace of Calayca, who was 20 at the time, was ever found.

While it is not known if she was the victim of foul play, police are not ruling it out.

At the time of her disappearance she was wearing a blue hoodie, a maroon/purple striped shirt, black pants and blue and white running shoes which fastened with Velcro.

Campers in the park are asked to report any signs of human remains, articles or pieces of clothing which match what she was wearing that day.
