An autopsy will be be performed on human remains found in a wooded area in Springwater Township.
OPP say a person out walking their dog in Simcoe County Forest made the gruesome discovery just before noon on Wednesday.
The remains are expected to be removed on Thursday but authorities say this may be difficult because of a great deal of snow and ice on the ground.
The remains have not yet been identified and police are not saying whether foul play is involved.
A post-mortem examination is scheduled for Friday in Toronto.
