Ronald Keith Hallam, 66, was last seen on his property on Prosperity Line in Ashfield-Colborne-Wawanosh, Huron County, Ontario, at about 11:00 a.m. on March 25, 2009. He is described as a white male, 5 feet 8 inches, about 200 pounds, with greying, partially bald hair. At last sighting he was believed to be wearing a red and black lumberjack-style jacket, a black ball cap over a checkered hat, a dark grey t-shirt, light-colored work pants, and beige work boots.

Authorities believe Hallam walked from his residence toward the nearby Saratoga Swamp. The Ontario Provincial Police conducted extensive searches that included the Emergency Response Team, Canine Unit, and helicopter support; large numbers of local volunteers also joined the effort. Despite those searches, no trace of Hallam was found and initial leads produced no resolution. The Huron County OPP has periodically reissued appeals for public assistance as the investigation remains open.

If anyone saw Ronald around Prosperity Line or Saratoga Swamp on or after March 25, 2009, or has information that could help locate him, please contact the Huron County OPP.
