The OPP said in a news release that a body was found on Thursday morning in Short Hills Provincial Park, south of St. Catharines, and that the death is being treated as suspicious.
OPP investigators said in a news release there is "no evidence" to connect this death to the ongoing search for Shawn Kapadia, the 22-year-old Mississauga man who Toronto police believe was killed at a townhouse in the city then moved to the St. Catharines-Welland area.
In that case, police are concerned Kapadia's body may be encased in concrete because a backhoe was seen carrying a slab of concrete away from a rural home where Kapadia's car was found.
Police haven't identified the latest body found, nor determined the cause of death.
A post-mortem is scheduled for Friday in Hamilton.
Police have closed Short Hills park while the investigation is ongoing.
Anyone with information is asked to contact Det. Const. Derrick Robinson at 416-453-9804 or contact Crime Stoppers anonymously.
