Summary based on the NamUs case record (can2014006229) and
1 other sourceIn the winter of 1981, a 26-year-old man named Cyril Willard Thistle, also known as "Sonny," vanished from Brampton, Ontario. Family members last saw him in the vicinity of McLaughlin Road and Queen Street East. At the time of his disappearance, Cyril was described as a man with a fair complexion, light brown hair, and a thick moustache. A particularly distinct feature was a noticeable gap between his two front teeth.
Cyril, who identifies as Indigenous, was living a transient lifestyle at the time, frequently moving between Toronto and the Region of Peel. His disappearance left his family with questions that would linger for decades.
Before he was last seen in 1981, Cyril had a history of moving around and had previously resided in both Saskatchewan and Sudbury before 1980. The period following his last sighting is marked by uncertainty. One of the few clues from that time is a handwritten letter connected to Cyril that is dated April 1981. Despite being last seen in 1981, a formal missing person report was not filed with the police until August of 2013, more than thirty years after his family last had contact with him. This significant passage of time created immense challenges for the subsequent investigation into what happened to him.
For years, Cyril's family, including his son, author Jesse Thistle, has been searching for answers. The official investigation, led by Peel Regional Police, has been described as exhaustive, yet the trail has grown cold over the many years. In an effort to bring new life to the case and generate new leads, investigators released a composite sketch in September 2022, showing an age-progressed image of what Cyril might look like in his later years. The case represents the painful and enduring mystery of a man who disappeared without a trace, leaving behind a family searching for closure and a police force still seeking information from the public. The investigation into the disappearance of Cyril "Sonny" Thistle remains open.Last Seen: Jan 1, 1981
