Peel Regional Police say a man was found dead in an apartment unit in Mississauga on Saturday.
Police said they were called to the area of Hurontario Street and Glenn Hawthorne Boulevard just after midnight.
Officers said a man in his late 20s was located dead in a unit of an apartment building.
Police said the coroner attended the scene and deemed the death suspicious, prompting the homicide bureau to take charge of the investigation.
The results of a post-mortem, however, later led police to deem the death non-suspicious, officials said.
